Nokia Bell Labs - Future Impossible Series Videos

Picture Source: Cnet

Bell Labs, which has played a significant role in telecoms history and has a very glorious list of achievements created a collection of short films highlighting the brilliant minds who created the invisible nervous system of our society. Some of you may be aware that Bell Labs is now a part of Nokia but was previously part of Alcatel-Lucent, Lucent and AT&T before that.

The playlist with 5 videos is embedded below and short details of the videos follows that.


Video 1: Introduction

Introducing 'Future Impossible', a collection of short films highlighting the brilliant minds who created the invisible nervous system of our society, a fantastic intelligent network of wires and cables undergirding and infiltrating every aspect of modern life.


Video 2: The Shannon Limit

In 1948, father of communications theory Claude Shannon developed the law that dictated just how much information could ever be communicated down any path, anywhere, using any technology. The maximum rate of this transmission would come to be known as the Shannon Limit.  Researchers have spent the following decades trying to achieve this limit and to try to go beyond it.


Video 3: The Many Lives of Copper

In the rush to find the next generation of optical communications, much of our attention has moved away from that old standby, copper cabling. But we already have miles and miles of the stuff under our feet and over our heads. What if instead of laying down new optical fiber cable everywhere, we could figure out a way to breathe new life into copper and drive the digital future that way?


Video 4: The Network of You

In the future, every human will be connected to every other human on the planet by a wireless network. But that’s just the beginning. 

Soon the stuff of modern life will all be part of the network, and it will unlock infinite opportunities for new ways of talking, making and being. The network will be our sixth sense, connecting us to our digital lives. In this film, we ponder that existence and how it is enabled by inventions and technologies developed over the past 30 years, and the innovations that still lie ahead of us.


Video 5: Story of Light

When Alexander Graham Bell discovered that sound could be carried by light, he never could have imagined the millions of written text and audio and video communications that would one day be transmitted around the world every second on a single strand of fiber with the dimensions of a human hair.

Follow the journey of a single text message zipping around the globe at the speed of light, then meet the researchers that have taken up Bell’s charge.


For anyone interested, Wikipedia has a good detailed info on Bell Labs history here.

Updates from the 3GPP RAN 5G Workshop - Part 3

Continuing with the updates from 5G RAN workshop, part 1 and part 2 here.

Dish network wants to have a satellite based 5G network. A recent article from Light Reading shows the following:

Dish states that there are misconceptions about what satellite technology can deliver for 5G networks. Essentially Dish says that satellites will be capable of delivering two-way communications to support 5G.

A hybrid ground and space 5G network would use small satellites that each use a "spot beam" to provide a dedicated area of two-way coverage on the ground. This is different than the old model of using one satellite with a single beam to provide a one-way service like a TV broadcast over a landmass.

Dish argues that newer, smaller satellites, equipped with the latest multi-antenna arrays (MIMO) would allow for "ubiquitous connectivity through hybrid satellite and terrestrial networks," the operator writes. In this model, satellites could connect areas that it would be hard to network otherwise like mountains and lakes.

The presentation from Dish is as follows:

Alcatel-Lucent provided a whitepaper along with the presentation. The paper provides an interesting view of 5G from their point of view. Its embedded below:

The presentation from Kyocera focused on TD-LTE which I think will play a prominent role in 5G. In case of wide channels, TD-LTE can help predict the channel accurately, which is a drawback for FDD at high frequencies. Their presentation is available here.

The presentation from NEC focussed on different technologies that will play a role in 5G. Their presentation is available here.

The final presentation we will look at this time is by the South Korean operator, KT. What is interesting to see is that in the part 1 we saw in the chairman's summary that 5G will come in two phases; Rel-15 will be phase 1 and Rel-16 will be phase 2. In the summary slide in KT's presentation, it looks like they are going to consider Rel-14 as 5G. Its not at all surprising considering that Verizon has said that they want to commercialise 5G by 2017, even though 5G will not be fully specified according to 3GPP by then. Anyway, here is the presentation by KT.

Using 8T8R Antennas for TD-LTE

People often ask at various conferences if TD-LTE is a fad or is it something that will continue to exist along with the FDD networks. TDD networks were a bit tricky to implement in the past due to the necessity for the whole network to be time synchronised to make sure there is no interference. Also, if there was another TDD network in an adjacent band, it would have to be time synchronised with the first network too. In the areas bordering another country where they might have had their own TDD network in this band, it would have to be time synchronised too. This complexity meant that most networks were happy to live with FDD networks.

In 5G networks, at higher frequencies it would also make much more sense to use TDD to estimate the channel accurately. This is because the same channel would be used in downlink and uplink so the downlink channel can be estimated accurately based on the uplink channel condition. Due to small transmit time intervals (TTI's), these channel condition estimation would be quite good. Another advantage of this is that the beam could be formed and directed exactly at the user and it would appear as a null to other users.

This is where 8T8R or 8 Transmit and 8 Receive antennas in the base station can help. The more the antennas, the better and narrower the beam they can create. This can help send more energy to users at the cell edge and hence provide better and more reliable coverage there.  



How do these antennas look like? 8T8R needs 8x Antennas at the Base Station Cell, and this is typically delivered using four X-Polar columns about half wavelength apart. I found the above picture on antenna specialist Quintel's page here, where the four column example is shown right. At spectrum bands such as 2.3GHz, 2.6GHz and 3.5GHz where TD-LTE networks are currently deployed, the antenna width is still practical. Quintel’s webpage also indicates how their technology allows 8T8R to be effectively emulated using only two X-Polar columns thus promising Slimline antenna solutions at lower frequency bands. China Mobile and Huawei have claimed to be the first ones to deploy these four X-Pol column 8T8R antennas. Sprint, USA is another network that has been actively deploying these 8T8R antennas.

There are couple of interesting tweets that show their kit below:

In fact Sprint has very ambitious plans. The following is from a report in Fierce Wireless:

Sprint's deployment of 8T8R (eight-branch transmit and eight-branch receive) radios in its 2.5 GHz TDD LTE spectrum is resulting in increased data throughput as well as coverage according to a new report from Signals Research. "Thanks to TM8 [transmission mode 8] and 8T8R, we observed meaningful increases in coverage and spectral efficiency, not to mention overall device throughput," Signals said in its executive summary of the report.

The firm said it extensively tested Sprint's network in the Chicago market using Band 41 (2.5 GHz) and Band 25 (1.9 GHz) in April using Accuver's drive test tools and two Galaxy Note Edge smartphones. Signals tested TM8 vs. non-TM8 performance, Band 41 and Band 25 coverage and performance as well as 8T8R receive vs. 2T2R coverage/performance and stand-alone carrier aggregation.

Sprint has been deploying 8T8R radios in its 2.5 GHz footprint, which the company has said will allow its cell sites to send multiple data streams, achieve better signal strength and increase data throughput and coverage without requiring more bandwidth.

The company also has said it will use carrier aggregation technology to combine TD-LTE and FDD-LTE transmission across all of its spectrum bands. In its fourth quarter 2014 earnings call with investors in February, Sprint CEO Marcelo Claure said implementing carrier aggregation across all Sprint spectrum bands means Sprint eventually will be able to deploy 1900 MHz FDD-LTE for uplink and 2.5 GHz TD-LTE for downlink, and ultimately improve the coverage of 2.5 GHz LTE to levels that its 1900 MHz spectrum currently achieves. Carrier aggregation, which is the most well-known and widely used technique of the LTE Advanced standard, bonds together disparate bands of spectrum to create wider channels and produce more capacity and faster speeds.

Alcatel-Lucent has a good article in their TECHzine, an extract from that below:

Field tests on base stations equipped with beamforming and 8T8R technologies confirm the sustainability of the solution. Operators can make the most of transmission (Tx) and receiving (Rx) diversity by adding in Tx and Rx paths at the eNodeB level, and beamforming delivers a direct impact on uplink and downlink performance at the cell edge.

By using 8 receiver paths instead of 2, cell range is increased by a factor of 1.5 – and this difference is emphasized by the fact that the number of sites needed is reduced by nearly 50 per cent. Furthermore, using the beamforming approach in transmission mode generates a specific beam per user which improves the quality of the signal received by the end-user’s device, or user equipment (UE). In fact, steering the radiated energy in a specific direction can reduce interference and improves the radio link, helping enable a better throughput. The orientation of the beam is decided by shifting the phases of the Tx paths based on signal feedback from the UE. This approach can deliver double the cell edge downlink throughput and can increase global average throughput by 65 per cent.

These types of deployments are made possible by using innovative radio heads and antenna solutions.  In traditional deployments, it would require the installation of multiple remote radio heads (RRH) and multiple antennas at the site to reach the same level of performance. The use of an 8T8R RRH and a smart antenna array, comprising 4 cross-polar antennas in a radome, means an 8T8R sector deployment can be done within the same footprint as traditional systems.



Anyone interested in seeing pictures of different 8T8R antennas like the one above, see here. While this page shows Samsung's antennas, you can navigate to equipment from other vendors.

Finally, if you can provide any additional info or feel there is something incorrect, please feel free to let me know via comments below.

LTE-Hetnet (LTE-H) a.k.a. LTE Wi-Fi Link Aggregation (LWA)

We have talked about the unlicensed LTE (LTE-U), re-branded as LTE-LAA many times on this blog and the 3G4G Small Cells blog. In fact some analysts have decided to call the current Rel-12 non-standardised Rel-12 version as LTE-U and the standardised version that would be available as part of Release-13 as LTE-LAA.

There is a lot of unease in the WiFi camp because LTE-LAA may hog the 5GHz spectrum that is available as license-exempt for use of Wi-Fi and other similar (future) technologies. Even though LAA may be more efficient as claimed by some vendors, it would reduce the usage for WiFi users in that particular spectrum.

As a result, some vendors have recently proposed LTE/WiFi Link Aggregation as a new feature in Release-13. Alcatel-Lucent, Ruckus Wireless and Qualcomm have all been promoting this. In fact Qualcomm has a pre-MWC teaser video on Youtube. The demo video is embedded as follows:



The Korean operator KT was also involved in demoing this in MWC along with Samsung and Qualcomm. They have termed this feature as LTE-Hetnet or LTE-H.

The Korean analyst firm Netmanias have more detailed technical info on this topic.

Link aggregation by LTE-H demonstrated at MWC 2015 (Source: Netmanias)

As can be seen the data is split/combined in PDCP layer. While this example above shows the practical implementation using C-RAN with Remote Radio Head (RRH) and BaseBand Unit (BBU) being used, the picture at the top shows LTE Anchor in eNodeB. There would be a need for an ideal backhaul to keep latency in the eNodeB to minimum when combining cellular and WiFi data.

Comparison of link level Carrier Aggregation technologies (Source: Netmanias)

The above table shows comparison between the 3 main techniques for increasing data rates through aggregation; CA, LTE-U/LAA and LTE-H/LWA. While CA has been part of 3GPP Release-10 and is available in more of less all new LTE devices, LTE-U and LTE-H is new and would need modifications in the network as well as in the devices. LTE-H would in the end provide similar benefits to LTE-U but is a safer option from devices and spectrum point of view and would be a more agreeable solution by everyone, including the WiFi community.

A final word; last year we wrote a whitepaper laying out our vision of what 4.5G is. I think we put it simply that in 4.5G, you can use WiFi and LTE at the same time. I think LTE-H fulfills that vision much better than other proposals.

5G: A 2020 Vision

I had the pleasure of speaking at the CW (Cambridge Wireless) event ‘5G: A Practical Approach’. It was a very interesting event with great speakers. Over the next few weeks, I will hopefully add the presentations from some of the other speakers too.

In fact before the presentation (below), I had a few discussions over the twitter to validate if people agree with my assumptions. For those who use twitter, maybe you may want to have a look at some of these below:

5G: A 2020 Vision from eXplanoTech

In-flight broadband connectivity service with speeds up to 75Mbps

Came across the following Inmarsat press release:

The new network represents two world-beating achievements for Inmarsat and its partners. It will be the world’s first truly hybrid aviation network, consisting of an S-band satellite (Europasat), constructed by Thales Alenia Space, and a Europe-wide S-band ground network. Over the integrated network, based on state-of-the-art LTE technology and access to sufficient spectrum resources, Inmarsat will be offering airlines the world’s fastest in-flight broadband connectivity service with speeds up to 75Mbps, far in excess of the limited capabilities of North American ATG systems.

Alcatel-Lucent and Inmarsat will work together to develop the ground infrastructure component of the new Europe-wide network. Alcatel-Lucent has proven expertise in the development of 4G LTE-based air-to-ground technology and was the world’s first company to field trial this technology in 2011. The initial contract awarded to Alcatel-Lucent will see the global telecommunications equipment company adapting their existing 4G LTE technology to support the S-band spectrum.

Recently Christophe WILHELM, Senior VP Strategy & Innovation, Thales Alenia Space gave a presentation in the Digiworld Summit 2014.

His presentation is above and the video is as follows. Please forward to 1:36:00 to watch his part

What is (pre-5G) 4.5G?

Before we look at what 4.5G is, lets look at what is not 4.5G. First and foremost, Carrier Aggregation is not 4.5G. Its the foundation for real 4G. I keep on showing this picture on Twitter

I am sure some people much be really bored by this picture of mine that I keep showing. LTE, rightly referred to as 3.9G or pre-4G by the South Korean and Japanese operators was the foundation of 'Real' 4G, a.k.a. LTE-Advanced. So who has been referring to LTE-A as 4.5G (and even 5G). Here you go:

Got 4G? Wake up, grandad. We're doing 4.5G LTE-A in London - EE chief: And get a load of our gleaming voice system! … http://t.co/78HSHlyPuA
— The Register (@TheRegister) March 5, 2014

Voda UK PR says: "The new technology, called Carrier Aggregation but also referred to as LTE Advanced or 4.5G" 4.5G?
— Keith Dyer (@keithdyer) October 15, 2014

5G wireless technology LTE-Advanced is now running in the Philippines' largest and strongest network. | http://t.co/g8u3lJ8sLV #Smart5G
— Smart Communications (@SMARTCares) August 14, 2014

So lets look at what 4.5G is.

Back in June, we published a whitepaper where we referred to 4.5G as LTE and WiFi working together. When we refer to LTE, it refers to LTE-A as well. The standards in Release-12 allow simultaneous use of LTE(-A) and WiFi with selected streams on WiFi and others on cellular.

Some people dont realise how much spectrum is available as part of 5GHz, hopefully the above picture will give an idea. This is exactly what has tempted the cellular community to come up with LTE-U (a.k.a LA-LTE, LAA)

In a recent event in London called 5G Huddle, Alcatel-Lucent presented their views on what 4.5G would mean. If you look at the slide above, it is quite a detailed view of what this intermediate step before 5G would be. Some tweets related to this discussion from 5G Huddle as follows:

Good points: 4.5G as necessary step: CA, VoLTE & WebRTC, CoMP & coordination, NFV & cloud. But that can do everything we need #5GHuddle
— Real Wireless (@real_wireless) September 23, 2014

So 5G will be evolution of 4.5G using DC & CA - but much better signalling, more energy efficient as new air interface for IoT
— Real Wireless (@real_wireless) September 23, 2014

Finally, in a recent GSMA event, Huawei used the term 4.5G to set out their vision and also propose a time-frame as follows:

While in Alcatel-Lucent slide, I could visualise 4.5G as our vision of LTE(-A) + WiFi + some more stuff, I am finding it difficult to visualise all the changes being proposed by Huawei. How are we going to see the peak rate of 10Gbps for example?

I have to mention that I have had companies that have told me that their vision of 5G is M2M and D2D so Huawei is is not very far from reality here.

We should keep in mind that this 4G, 4.5G and 5G are the terms we use to make the end users aware of what new cellular technology could do for them. Most of these people understand simple terms like speeds and latency. We may want to be careful what we tell them as we do not want to make things confusing, complicated and make false promises and not deliver on them.

Chinese vendor ZTE has said it plans to launch a ‘pre-5G’ testing base station in 2015, commercial use of which will be possible in 2016, following tests and adjustment. Here is what they think pre-5G means:

ANDSF: Evolution and Roaming with Hotspot 2.0

Access Network Discovery and Selection Function (ANDSF) is still evolving and with the introduction of Hotspot 2.0 (HS 2), there is a good possibility to provide seamless roaming from Cellular to Wi-Fi, Wi-Fi to Wi-Fi and Wi-Fi to Cellular.

There is a good paper (not very recent) by Alcatel-Lucent and BT that explains these roaming scenarios and other ANDSF policies related information very well. Its embedded below:

What is Network Function Virtualisation (NFV)?

Software Defined Networking (SDN) and Network Function Virtualization (NFV) are the two recent buzzwords taking the telecoms market by storm. Every network vendor now has some kind of strategy to use this NFV and SDN to help operators save money. So what exactly is NFV? I found a good simple video by Spirent that explains this well. Here it is:


To add a description to this, I would borrow an explanation and a very good example from Wendy Zajack, Director Product Communications, Alcatel-Lucent in ALU blog:

Let’s take this virtualization concept to a network environment. For me cloud means I can get my stuff where ever I am and on any device –  meaning I can pull out my smart phone, my iPad, my computer – and show my mom the  latest pictures of  her grand kids.  I am not limited to only having one type of photo album I put my photos in – and only that. I can also show her both photos and videos together – and am not just limited to showing her the kids in one format and on one device.

Today in a telecom network is a lot of equipment that can only do one thing.  These machines are focused on what they are do and they do it really well – this is why telecom providers are considered so ‘trusted.’ Back in the days of landline phones even when the power was out you could always make a call.  These machines run alone with dedicated resources.  These machines are made by various different vendors and speak various languages or ‘protocols’ to exchange information with each other when necessary. Some don’t even talk at all – they are just set-up and then left to run.  So, every day your operator is running a mini United Nations and corralling that to get you to access all of your stuff.  But it is a United Nations with a fixed number of seats, and with only a specific nation allowed to occupy a specific seat, with the seat left unused if there was a no-show. That is a lot of underutilized equipment that is tough and expensive to manage.  It also has a shelf life of 15 years… while your average store-bought computer is doubling in speed every 18 months.

Virtualizing the network means the ability to run a variety of applications (or functions) on a standard piece of computing equipment, rather than on dedicated, specialized processors and equipment, to drive lower costs (more value), more re-use of the equipment between applications (more sharing), and a greater ability to change what is using the equipment to meet the changing user needs (more responsiveness).  This has already started in enterprises as a way to control IT costs and improve the performance and of course way greener.

To give this a sports analogy – imagine if in American football instead of having specialists in all the different positions (QB, LB, RB, etc), you had a bunch of generalists who could play any position – you might only need a 22 or 33 man squad (2 or 3 players for every position) rather than the normal squad of  53.   The management of your team would be much simpler as ‘one player fits all’ positions.   It is easy to see how this would benefit a service provider – simplifying the procurement and management of the network elements (team) and giving them the ability to do more, with less.

Dimitris Mavrakis from Informa wrote an excellent summary from the IIR SDN and NFV conference in Informa blog here. Its worth reading his article but I want to highlight one section that shows how the operators think deployment would be done:

The speaker from BT provided a good roadmap for implementing SDN and NFV:

1. Start with a small part of the network, which may not be critical for the operation of the whole. Perhaps introduce incremental capacity upgrades or improvements in specific and isolated parts of the network.
2. Integrate with existing OSS/BSS and other parts of the network.
3. Plan a larger-scale rollout so that it fits with the longer-term network strategy.

Deutsche Telecom is now considered to be deploying in the first phase, with a small trial in Hrvatski Telecom, its Croatian subsidiary, called Project Terrastream. BT, Telefonica, NTT Communications and other operators are at a similar stage, although DT is considered the first to deploy SDN and NFV for commercial network services beyond the data center.

Stage 2 in the roadmap is a far more complicated task. Integrating with existing components that may perform the same function but are not virtualized requires east-west APIs that are not clearly defined, especially when a network is multivendor. This is a very active point of discussion, but it remains to be seen whether Tier-1 vendors will be willing to openly integrate with their peers and even smaller, specialist vendors. OSS/BSS is also a major challenge, where multivendor networks are controlled by multiple systems and introducing a new service may require risking several parameters in many of these OSS/BSS consoles. This is another area that is not likely to change rapidly but rather in small, incremental steps.

The final stage is perhaps the biggest barrier due to the financial commitment and resources required. Long-term strategy may translate to five or even 10 years ahead – when networks are fully virtualized – and the economic environment may not allow such bold investments. Moreover, it is not clear if SDN and NFV guarantee new services and revenues outside the data center or operator cloud. If they do not, both technologies – and similar IT concepts – are likely to be deployed incrementally and replace equipment that reaches end-of-life. Cost savings in the network currently do not justify forklift upgrades or the replacement of adequately functional network components.

There is also a growing realization that bare-metal platforms (i.e., the proprietary hardware-based platforms that power today’s networks) are here to stay for several years. This hardware has been customized and adapted for use in telecom networks, allowing high performance for radio, core, transport, fixed and optical networks. Replacing these high-capacity components with virtualized ones is likely to affect performance significantly and operators are certainly not willing to take the risk of disrupting the operation of their network.

A major theme at the conference was that proprietary platforms (particularly ATCA) will be replaced by common off-the-shelf (COTS) hardware. ATCA is a hardware platform designed specifically for telecoms, but several vendors have adapted the platform to their own cause, creating fragmentation, incompatibility and vendor lock-in. Although ATCA is in theory telecoms-specific COTS, proprietary extensions have forced operators to turn to COTS, which is now driven by IT vendors, including Intel, HP, IBM, Dell and others.

ETSI has just published first specifications on NFV. Their press release here says:

ETSI has published the first five specifications on Network Functions Virtualisation (NFV). This is a major milestone towards the use of NFV to simplify the roll-out of new network services, reduce deployment and operational costs and encourage innovation.

These documents clearly identify an agreed framework and terminology for NFV which will help the industry to channel its efforts towards fully interoperable NFV solutions. This in turn will make it easier for network operators and NFV solutions providers to work together and will facilitate global economies of scale.

The IT and Network industries are collaborating in ETSI's Industry Specification Group for Network Functions Virtualisation (NFV ISG) to achieve a consistent approach and common architecture for the hardware and software infrastructure needed to support virtualised network functions. Early NFV deployments are already underway and are expected to accelerate during 2014-15. These new specifications have been produced in less than 10 months to satisfy the high industry demand – NFV ISG only began work in January 2013.

NFV ISG was initiated by the world's leading telecoms network operators. The work has attracted broad industry support and participation has risen rapidly to over 150 companies of all sizes from all over the world, including network operators, telecommunication equipment vendors, IT vendors and technology providers. Like all ETSI standards, these NFV specifications have been agreed by a consensus of all those involved.

The five published documents (which are publicly available via www.etsi.org/nfv) include four ETSI Group Specifications (GSs) designed to align understanding about NFV across the industry. They cover NFV use cases, requirements, the architectural framework, and terminology. The fifth GS defines a framework for co-ordinating and promoting public demonstrations of Proof of Concept (PoC) platforms illustrating key aspects of NFV. Its objective is to encourage the development of an open ecosystem by integrating components from different players.

Work is continuing in NFV ISG to develop further guidance to industry, and more detailed specifications are scheduled for 2014. In addition, to avoid the duplication of effort and to minimise fragmentation amongst multiple standards development organisations, NFV ISG is undertaking a gap analysis to identify what additional work needs to be done, and which bodies are best placed to do it.

The ETSI specifications are available at: http://www.etsi.org/technologies-clusters/technologies/nfv

Extending 4G Communications with WebRTC IMS and WebRTC from Zahid Ghadialy

Dean Bubley from Disruptive Analysis has writted extensively on this topic and his recent post "Is the telephony "threat" from VoIP & WebRTC about competition or contextualisation?" is an interesting read.

Iain Sharp from Netovate recently pointed out that 3GPP have 'nearly' approved a work item for WebRTC access to IMS.

It would be interesting to see how operators will view WebRTC. As an opportunity or as a threat. Please feel free to air your opinions via comments.

@lesanto: SS "deploying more small cells decreases network interference if managed properly"

@lesanto: SS "it is very heartening to see operators today deploying Femtocells successfully, we're seeing a great deal of maturity"

@thinksmallcell: Operators are finding the cost savings, churn reduction of femtocells to be much better than originally forecast - Simon Saunders

@lesanto: SS "Key attributes of small cells include Scalability, Automated configuration and optimisation..."

@lesanto: SS "we see the need and opportunity to do even more with small cells"

@Ubiquisys: "Our work today is about differentiating the technology to fit different environments"

@lesanto: "60% of operators surveyed consider small cells will be more important to LTE deployments than macrocells"

@LisaGCisco: Chair Simon Saunders highlights the Small Cell Forum work areas that include home, enterprise, metro and rural small cells

@stewartbaines: Simon Saunders: i struggle to find an operator that does not have small cells on their roadmap

@lesanto: go to http://smallcellforum.org where you can download the Small Cells Market Status report (free)

@lesanto: Small Cells forum now has 76 technology providers as members

@lesanto: In 2007 commercial deployment of small cells = zero -- now we have 41 operators deploying them commercially, including 9 of top 10

@bmbarnowski: great retrospective on the evolution of the femtocell/smallcell forum by SS … 2007 was a lonely year indeed for femtos ..

@lesanto: small cell deployment was once solely focussed on domestic deployment, now deployment is much broader inc commercial

@lesanto: 3.8 million femtocells deployed commercially worldwide

@Alejandro_Avren: 3.8 million femtocells deployed globally, says simon saunders of the small cell forum 

@lesanto: several deployments have reached real scale, such as Sprint : over 600,000 units deployed

@lesanto: there will be more small cells deployed than macrocells by the end of 2012

@lesanto: to summarise : small cells have properly arrived ;0)

@Ubiquisys: By the end of 2012 there will be more Small Cells (6.4m) than Macro Cells

@thinksmallcell: forecast 6.4million small cells by end 2012 = more than all global macrocells all technologies

@lesanto: prediction: 91.9 million small cells will be deployed worldwide by end of 2016

@MarkBLHenry: Simon Saunders: "... The central magic of cellular is spectrum reuse..."

@lesanto: small cells offer a very substantial opportunity to increase capacity in a network

@stewartbaines: Simon Saunders: more small cells (6.4m) than macro (6m) by end of year. 80% all cells will be titchy by 2016 #SCWS2012. I got 2 of them :)

@lesanto: small cells can offer real positive change for the user experience on a 3g network

@lesanto: wi-fi and small cells need integration - they should be deployed in cooperation

@disruptivedean: Survey results at #SCWS2012 about coexistence & integration of Small Cells & WiFi point to wishful & unrealistic thinking about #HetNets

@lesanto: we see the opportunity for a deeper integration of small cells and wifi

@disruptivedean: Just had further evidence about slow/misguided focus of Carrier WiFi. WBA announced a trial of NGH WiFi starting Q4 #TooSlow

@lesanto: 2011 Small Cells Forum published small cell APIs

@Ubiquisys: The two overriding themes of @SmallCell_Forum's work are: a) Open and b) Multi-technology 

@disruptivedean: My summary of intro at #SCWS2012: Good move shifting from femto to broader small-cells. Looking bright for LTE. Unconvinced by WiFi pitch

@lesanto: "Vodafone's strategy is to drive Small Cells from a customer needs perspective"

@lesanto: products such a Vodafone's 'sure signal' need to be plug and play, easy to install and use

@SmallCell_Forum: 3.8 million femtocells deployed globally today #SCWS2012. Market status report now at: http://www.smallcellforum.org/resources-white-papers

@lesanto: Vodafone are now running a trial of commercial small cells in Germany with great feedback already

@thinksmallcell: Vodafone to launch enterprise femtocells in Germany 2013. Good feedback from trials so far

@lesanto: data is becoming continually more important to customers, and they also want less wires and network devices in their homes

@thinksmallcell: Vodafone showcasing new FemtoPlug - embedded femtocell into a small mains plug. 8 calls 21Mb/s. Sagemcom and ALU suppliers.

@lesanto: enterprise customers are a very important segment of Vodafone's femtocell proposition - they want easy integration into their IT

@danieldotfox: Wow. The new Sure Signal product from #Vodafone looks amazing. Well thought out consumer proposition. Nice!

@SmallCell_Forum: Vodafone announces femtoplug: tiny femtocell with ethernet over mains. To be launched in existing markets 'within weeks'. 

@disruptivedean: Liking the new "femtoplug" products announced by Vodafone. Very neat residential femto integrated into electric plug. 

@lesanto: Present speaker, Alan Law, Technical Lead for femtocells, Vodafone Group...

@lesanto: "where do you put small cells? How can we determine where the hot spots are? Fortunately there are tools available to help here"

@lesanto: "geolocation tools can also be exploited for network quality improvements"

@Ubiquisys: "Geolocation can be used to identify traffic hotspots"

@lesanto: "Vodafone have gained essential experience on how to address challenges with public access small cells for many environments"

@lesanto: "the availability of multi-technology small cells eases deployment"

@lesanto: "accelerate availability of multi-technology small cells to reduce the number of site boxes required to ease deployment"

@lesanto: "it not just about network cover and quality - it is also about driving new services and revenue growth"

@lesanto: Next speaker : Sebastien Pham Programme Manager New Products Vodafone New Zealand.

@LisaGCisco: Vodafone's Alan Law underscores importance of Iuh standard to accelerate small cell market adoption 

@lesanto: Vodafone NZ faces the challenge of a relatively large area with a relatively low number of users.

@lesanto: 4.8 million mobile subscribers in 2011 in New Zealand - 97% 3g coverage (vodafone) - rural broadband is very challenging

@lesanto: Vodafone deploying small cells in homes in NZ, but their Sure Signal will only work on Vodafone's own DSL network.

@lesanto: watching a video on how small cells can help you make better mobile calls at home : are you hanging out a window to get a single?

@stewartbaines: Femtos bring broadband to rural communities in NZ:http://www.vodafone.co.nz/suresignal

@lesanto: plug in a Sure Signal small cell box into your DSL and suddenly you can make mobile calls from anywhere in the house!#sorted!

@stewartbaines: No more driving testing: use geolocation tools to identify traffic not-spots. Vodafone at #SCWS2012 #smallcells

@lesanto: Next vid: a small business in NZ in a building known as the bunker - thick concrete and steel walls = poor mobile reception!

@disruptivedean: Ironic that Small Cell industry finally getting enterprise proposition right, at same time that #BYOD drives #BYOSP in businesses 

@lesanto: yep, you've guessed it : they plug in a Sure Signal small cell and their mobiles all work - even inside the bunker ;0)

@stewartbaines: @katebo Orange is doing a prez on it's enterprise femtocell strategy at#SCWS2012. Will grab a post for Connecting Technology blog

@danieldotfox: Small Cell feedback via Vodafone.nz, from customers: It's life changing! We all need and depend on mobiles... Food for thought!

@lesanto: small cells were deployed during the Feb 2011 Christchurch earthquake to replace broken macro cells in certain essential areas

@Ubiquisys: Femtocells have been used in disaster situations for emergency coverage, such as the Christchurch earthquake 

@vodafoneNZ: @Ubiquisys Our network team did incredible work for Chch #eqnz. Used creative tools including the Truck http://bit.ly/NGPzM7

@lesanto: new speaker : Emmanuel Adnot International Strategy Manager at Orange...

@lesanto: Orange Group had $45bn turnover in 2011

@lesanto: talking about : How Femtocells support Orange's B2B strategy...

@lesanto: "coverage needs in enterprise markets are niche" Emmanuel Adnot, Orange (EA)

@lesanto: "10% of B2B customers have indoor mobile reception issues that effect their business"

@lesanto: "10% is a niche but it still represents a significant market"

@lesanto: "45% of those connectivity issues are suffered in basement or storeroom situations" EA

@lesanto: "80% of customers suffering local connectivity issues are ready to move to an operator offering a solution to the problem"

@lesanto: "small cells are part of the B2B indoor coverage strategy" EA

@lesanto: "30% of B2B users are using smartphones - but that share is growing massively"

@lesanto: small b2b customers need both wi-fi and small cell solutions to answer their connectivity issues

@lesanto: "small cell installation reduced churn by almost 50% where connectivity had previously been an issue"

@lesanto: "B2B customers suffering indoor connectivity problems are ready to pay for small cell solutions"

@lesanto: "Orange will launch small cell solutions to the UK market in summer 2012"

@danieldotfox: In Portugal, #Orange cam charge over €1000 for a B2B femto. Wow.

@stewartbaines: Orange study: 80% of business customers ready to churn if their coverage issues are not addressed. #SCWS2012. Similar to Alcatel research...

@SmallCell_Forum: Orange: PT, FR, Romania B2B femtocells launched, 2 more countries to be launched (UK, Be) by end 2012 #scws2012 plus Poland next year

@stewartbaines: Small cells can be basis for location-based services. Stop the dumb pipe!

@lesanto: "what's next? Femtocell as a service for small operations..

@lesanto: "what's next: femtocell and other techs within a small cell - leverage indoor coverage solution for location based services"

@Ubiquisys: What's next for B2B femtocell solutions? Here's @orange's outlook

@lesanto: why are Orange concentrating on B2B for small cells? Could it be the cost? I can't see many consumers paying $1500 a pop!

@lesanto: but Orange haven't ruled out bringing small cells to the consumer...

@dmavrakis: Orange believes that SMBs that have coverage problems are willing to pay €1500 for an access point.

@stewartbaines: Orange France enterprise femtos cost 1500 euros. But you do get a visit from an engineer. I thought they were plug & play?

@lesanto: next speaker : Martin Guthrie - head of business development - NEC

@lesanto: MG "small cells are beautiful"

@lesanto: "the world is getting smaller, so are macro cells"

@lesanto: "smaller and smaller cell sizes are an inevitability along with the technical and cost benefits they bring"

@lesanto: " many small cells advantages : better coverage, greater capacity gain, higher density coverage"

@lesanto: "business case benefits of small cells are not fully understood"

@Ubiquisys: The elephant in the small cells room is dichotomy between vendors: "look at our tech" & operators: "how can we make money?" @NEC

@lesanto: "benefits: reduced customer churn : increased customer acquisition : reduced cost of new macro deployment : "

@lesanto: " more benefits: leverage presence of mobile operator in the home : Increased ARPU "

@Ubiquisys: "Integration with operators' existing network and system is key" @NEC

@lesanto: technical and marketing support is essential when deploying small cells - choose your vendor carefully!

@lesanto: "make sure that your small cell solutions use advanced & adaptive radio management technologies that won't interfere with macro"

@lesanto: Next speaker : Mark Gallagher Principle Engineer, Cisco

@lesanto: "mass adoption of the mobile internet is going on right now - scaling to meet this demand is the challenge"

@Ubiquisys: The next speaker is Mark Gallagher of @CiscoSystems "Defining the New Normal"

@small_cells: "usage patterns in mobile internet are as important as the size of use"

@disruptivedean: Watching Cisco at #SCWS2012 . Think that it's underestimating % of smartphone data that goes via WiFi, only small % of which is offload

@small_cells: "network densification is required : small cell development = highly dense topologies"

@Ubiquisys: "Network densification is required. Small cell deployment = highly dense topologies" @CiscoSystems

@small_cells: "you must use all the spectrum assets available to you"

@small_cells: globally available data sources can be incorporated into RF planning tools to give a clear picture of where to add small cells

@small_cells: "you need a simple, scaleable small cell solution that's properly managed"

@small_cells: "there is significant revenue potential in the small cell business model" -- think beyond simply making savings

@small_cells: "Small cells really are the new norm"

@Ubiquisys: London hotspots map shows usage, including tweets & Flickr photos, identifies small cell deployment locations.

@Ubiquisys: Small cells future built around growing penetration of mobile internet. Take learnings from adjacent markets.

@Lance_Hiley: #ciscosystems shows geolocation tool to identify potential #smallcellsdeployment locations using #flicker and #twitter uploads

@small_cells: "small cells are splitting into two categories : capacity and coverage"

@small_cells: "how can we cope with the data tsunami that's coming at us?"

@small_cells: "the cost difference between a small cell and a macro is large"

@Ubiquisys: Joe Madden of Mobile Experts on Small cell economics and time-to-market

@small_cells: "with data growth doubling every year you really need to plan ahead to cope"

@Ubiquisys: Data growth in US will not be uniform. Most data is consumed in downtown metro areas.

@small_cells: "imagine if it was your job to find sites for 28,000 new macro masts per year to cope with data demand!"

@Ubiquisys: Balanced solution = towers in the rural areas, picocells in urban areas.

@stewartbaines: Joe Madden: It worries me that operators are talking small cells only for LTE. You need a balance (small + macro)

@lesanto: "operators are not keeping up with the data curve, I don't see them spending enough capital to keep up with demand"

@lesanto: "I think we're going to fall behind data demand in a serious way in 2015/2016"

@Ubiquisys: Operators won't be able to keep up with data demand. Be ready to ship millions of picocells in next few years.

@lesanto: "when customers want to use more data than they can get we'll have unhappy customers and that means churn"

@disruptivedean: HIghly questionable supply/demand curve at #SCWS2012 that doesn't cover impact of pricing & policy management constraining "demand"

@lesanto: "those unhappy customers will force operators to make choices they hadn't previously wanted to make for economic reasons"

@stewartbaines: Joe Madden: be ready to ship millions of small cells, whether cheapest or not, by 2015

@lesanto: "we are projecting high numbers of small cells because of time-to-Market issues..."

@lesanto: The #London2012 olympics throws up a real challenge for mobile operators - small cells are already installed for the event.

@danieldotfox: #O2UK has 100 small cells within the London area.

@Ubiquisys: Currently on stage, Robert Joyce of Telefonica. Case study: delivering small cells into the heart of central London

@SmallCell_Forum: O2 says "small cells are the only way" for future capacity, even factoring on extra spectrum and LTE-A.

@lesanto: "2g hotspots aren't in the same place as 3g hotspots so replacing existing 2g small cells for 3g cells won't always bring results"

@danieldotfox: #O2UK really like 'open' femto cells. Interesting!

@lesanto: O2 bid on access to street furniture, street lamps etc, in order to use them to provide wi-fi and small cells

@lesanto: BUT, once O2 had the poles they discovered the councils wanted planning permission for each and every lamppost installation...

@stewartbaines: O2: 400 individual planning applications required to deploy metro wifi in Kensington and Westminster. Ouch!

@lesanto: O2 also had to considerer the form factor of the installations, London lampposts are not suitable for big set upis!

@lesanto: O2's London network is fed both 'over the street' and 'under it' - using a mix of masts, cells and fibre...

@lesanto: O2's mobile network plan for London aims to serve a Gig per Km2

@lesanto: O2 have 12 access points for mobile in Trafalgar Square alone

@lesanto: You lot should see just how complex serving mobile to the streets of London is. Remember this next time you complain about signal

@lesanto: Olympic village buildings are clad in aluminium for heat retention - this also locks out mobile signals!

@lesanto: the result is the Olympic village has become probably the densest installation of small cells anywhere...

@SmallCell_Forum: O2 have deployed 1200 femtos in a in an apartment block for some 'very healthy people' (!) in London for this summer

@lesanto: O2 want to use their Olympic experience to roll out small cells elsewhere - but say the price has to come down!

@joelpagot: @wendyzajack nice pic! #smallcells also come in "green" (low-power mobile devices)

@Ubiquisys: Here's a prototype solar powered small cell. Interesting concept.

@joelpagot: @Ubiquisys Good example for #GreenICT #smallcells big impact: more capacity for less

@SmallCell_Forum: After announcements by O2 and Orange today, is UK first market in world where all operators have publically announced femtocells?

@thinksmallcell: O2 deployed 1Gb/s per square kilometre capacity onstreet 3G/WiFi in London using Small Cells - believe will meet forecast demand

@Lance_Hiley: Telefonica's Rob Joyce forecasts 1Gb/s per km #backhaul requirement for London #smallcells by 2015.

@disruptivedean: @Lance_Hiley Quite astonishing to think that 1sq km use of mobile data in 2015 is only equivalent of a single FTTH broadband cnxn

@markc_reed: “@thinksmallcell: O2 deployed 1Gb/s per square kilometre capacity in London using Small demand #SCWS2012” what about install & bhaul cost?

@lesanto: Manish Singh CTO of Radisys is now on the stand

@Ubiquisys: @radisys: Over the next three years, which sources of disruption will have the greatest impact on mobile operators?

@disruptivedean: Radisys survey at #SCWS2012 shows operators still think "good user experience" = seamless WiFi authentication & handover. Very wrong indeed

@Ubiquisys: You need a portfolio of products to address different segments. Requirements are evolving, so flexibility is a must. @radisys

@thinksmallcell: 46% of operators surveyed said logistics and deployment model were barriers to rapid small cell rollout - Radisys survey

@danieldotfox: #O2UK state that 1Gbit per square kilometer is needed for sufficient outdoor data capacity within 2015 timeframe. Crikey.

@Ubiquisys: NGMN Alliance's Julius Robson is talking about small cell specific backhaul requirements

@lesanto: The relentless growth of data consumption - can we handle it? http://smallcells.posterous.com/the-relentless-growth-of-data-consumption-can via @small_cells

@Ubiquisys: Deployment prerequisites for small cell deployment: unserved demand, suitable site, backhaul connectivity #NGMN

@Ubiquisys: Small cell devices are more visible than macros and need to be small, light, touch safe and tamper proof

@stewartbaines: Wilson Street post from #SCWS2012: Orange or Vodafone taking best approach to femtos? - http://www.wilson-street.com/2012/06/scws2012-femtocells-pile-them-high-and-sell-them-cheap-or-keep-them-for-the-most-valuable-customers/

@lesanto: Somewhat technical this presso... not eminently tweetable see "security of LTE backhauling" white paper by ngmn - http://www.ngmn.org/uploads/media/NGMN_Whitepaper_Backhaul_Security.pdf

@Ubiquisys: Small cell backhaul connections are viewed as untrusted and may need IPsec encryption

@lesanto: "backhaul is a key enabler for small cells, but there is uncertainty around which solutions are suitable"

@Ubiquisys: Backhaul white paper is available at http://www.ngmn.org/fileadmin/user_upload/Downloads/Technical/NGMN_Whitepaper_Small_Cell_Backhaul_Requirements.pdf

@lesanto: The streets of London are paved with small cells #SCWS2012 http://smallcells.posterous.com/the-streets-of-london-are-paved-with-small-ce via @small_cells

@Lance_Hiley: Availability of #smallcells can be relaxed in hotspot deployment scenario says Julius Robson, editor of @ngmn_alliance Whitepaper

@lesanto: since the show started this morning we have seen 5% growth in the industry as two major mobile operators have adopted small cells

@SmallCell_Forum: France & UK first countries globally where all mobile operators have announced femtocells.

@lesanto: majority of South Koreans using LTE networks by 2014

@lesanto: South Korea enjoys one of the highest adoptions of high speed networks in the world

@lesanto: SK telecom launched the world's first LTE + wi-fi femtocell network in 2011

@lesanto: SK telecom is preparing for the PETA byte era - which is next year! 1 PETA = 10 to the power of 15 bytes.

@stewartbaines: @lesanto Key thing about the petabyte era, is SK Telecom will has 1 petabyte PER DAY on their mobile network.

@lesanto: Small cells can provide extended coverage at lower cost

@lesanto: "For interference mitigation in small cell deployment, a central interference management system is being developed"

@Ubiquisys: Nick Karter of @qualcomm will now talk about the convergence of 3G, 4G and wifi

@lesanto: "the growth in data traffic is outstripping the ability to put new spectrum on the market" (say it again)

@lesanto: "there is an increase in operator provided wi-fi"

@lesanto: "wi-fi is already a small cell but without all the features you expect from a mobile network"

@lesanto: "Hotspot 2.0 - converging the wi-fi and cellular networks"

@lesanto: "people use cellular primarily for email and facebook, while they use wi-fi for youtube"

@lesanto: "optimising power consumption is critical when combining so many functions into one box"

@lesanto: "you need a good application processor to manage the network efficiently"

@lesanto: providing mobile data is extremely complex - it's a typical swan swimming scenario, serene above the surface, mad action below it.

@Ubiquisys: Need for RF coordination with coexistence of Wi-Fi and LTE. Optimising power limitation is critical. @qualcomm

@lesanto: "security is obviously very critical to a mobile network"

@lesanto: "Hotspot 2.0 - the mission is to make wi-fi connectivity (of mobile devices) as seamless and easy as cellular"

@danieldotfox: The #Qualcomm approach to multiradio/multi spectrum type access points looks good. Mixed in with Hotspot 2.0. Smart thinking.

@Ubiquisys: Manish Gupta of Symmetricomm: Timing and synchronisation for small cells

@Ubiquisys: Small cells defined: Residential, Enterprise, Metro. What is the distinction?

@Ubiquisys: Panel discussion coming up at #SCWS2012: Backhaul challenges for small cell deployment

@Ubiquisys: Rural environment small cell deployments vary wildly. Any data connection is better than zero in many remote areas

@lesanto: rain can degrade mobile network performance. They call it 'rain fade' - #WhoKnew? see: http://searchmobilecomputing.techtarget.com/definition/rain-fade

@LisaGCisco: Multi-operator white label small cells might be a solution to the complexity and cost of multiple public small cell networks

@Ubiquisys: "GPS is great, but make sure you have a back up" #SCWS2012 panel

Day 1 Summaries:

• ABI Research: Small Cells World Summit 2012 - Day 1
• Ubiquisys: Small Cells World Summit 2012: What happened on day one?
• Official Blog: Small cells get smaller while the small cell world expands

DAY 2

@Ubiquisys: First speaker this morning : Matthew D Brown, Marketing Product Manager, Femtocell, Optus Australia

@lesanto: Matthew Brown Marketing Product Manager Femtocell, Optus Aus. "delivering femtocells to market isn't just about technical aspects"

@stewartbaines: Optus: coverage is still the massive factor in acquisition and retention in Australia

@small_cells: Matthew is treating us to a case study on marketing femtocells to the challenging Australian mobile market

@small_cells: "we decided to include the additional benefit of unlimited calls in a femtocell tariff"

@LisaGCisco: Optus 3G Home Zone provides a value add with unlimited calling according to Optus Product Manager Matthew Brown

@small_cells: Optus consumer marketing video promises 5 bars of mobile signal and unlimited calls - a dual message

@small_cells: Optus marketing strategy was to lead strongly with coverage message and value proposition of tariff

@SmallCell_Forum: Optus Australia: unlimited femtocell voice calls cheaper than a latte

@small_cells: "we managed to mitigate the negative effect of it seeming like they were paying for coverage, hence the unlimited calls package"

@small_cells: "our initial commercial pilots taught us about the big challenge of integrating the femtocell with a variety of different modems"

@small_cells: "this product needs a seamless deployment, it must just plug and play - the consumer is short of patience with set up"

@stewartbaines: Optus: key to residential femto success...5 bar coverage AND differentiated (free standard national) calling from home

@small_cells: Optus have a lot of useful experience with consumer femtocell deployment, it's well worth learning the lessons they've learned!

@stewartbaines: I never realized my femto should be 1m away from my WiFi. You learn something new everyday!

@small_cells: "customers really enjoy the benefit of the connectivity, they absolutely love it - the challenge is how to price that service"

@small_cells: Great presentation from Matthew, lots of useful practical information from the Optus femtocell experience

@stewartbaines: Optus: next steps is presence-based apps and further differentiated pricing.

@stewartbaines: Optus: we're looking for presence-based apps/services for femtos. Anyone got a case study?

@small_cells: next speaker : Xiaojia Liu, Deputy General, Manager of Technology, China Unicom

@small_cells: "wireless network evolution is ongoing"

@small_cells: "more than 40 launches of the LTE network and 200 more commitments"

@small_cells: "LTE-A requires a 1gbs downlink"

@small_cells: "limited coverage of macro sites will become a very big problem"

@small_cells: Service Development Trends: Phones once used for voice call and SMS - now various uses and services including HD TV.

@Ubiquisys: As smartphone use grows, user habits have changed. There are now billions of 'always-on' customers

@small_cells: "40 - 60% mobile calls taking place indoors" leading to connectivity and capacity issues

@small_cells: "densely populated areas lead to more interference between installed femtocells requiring better interference handling technology"

@small_cells: "two deployment scenarios: Hotspot scenario and rural scenario - both requiring different solutions"

@Ubiquisys: Dense scenario is more suited to #China. Need a flexible, intelligent interfence coordination method #Chinacom

@small_cells: "main objective scenario : coverage (for) holes and hotspots"

@small_cells: "one objective of small cells is to minimise CAPEX and OPEX"

@Ubiquisys: Broadband resource, cost per unit and construction complexity should be taken into account in deployment #Chinacom

@small_cells: "small cells seem more flexible and give more choices for operator deployment"

@small_cells: "small cells bring more: higher capacity, better micro-offload, enhanced user experience"

@small_cells: "with small cells we can do more"

@stewartbaines: Is China Unicom suggesting handover between individual HeNBs?

@MarcianoGilbert: China Unicom: 2 small cells rollout scénario: Hotspot (close, semiopen, open for M2M use) & rural; Wifi + Cellular in tandem.

@Ubiquisys: Operators could provided new types of revenue-generating services in small cell development

@SmallCell_Forum: China Unicom: Small Cell Forum has important role in standardisation, comms, cooperation and IoT testing for small cell evolution

@LisaGCisco: Xiao Han China Unicom underscores key role of Small Cell Forum in increasing industry adoption through standardization and IOT

@MarcianoGilbert: China Unicom 10 provinces for precommercial network in small cells #ALU @SmallCell_Forum @Alcatel_Lucent

@lesanto: *very* detailed presentation from China Unicom - hope the slides are available for careful study later...

@SmallCell_Forum: China Unicom: X2 interface is a key component for managing interference in LTE: welcomes news that SCF is working on X2 interop

@small_cells: Next speaker: Mike Schabel - VP LightRadio, Alcatel-Lucent "Metro Cell : Thinking outside the box"

@small_cells: MS "I'd like to share our experiences with introducing LightRadio"

@small_cells: "there is a lot to extract from spectral efficiency - 1x or 2x capacity improvement"

@small_cells: "operators continue to lobby for more spectrum, including adding wi-fi"

@small_cells: "but we really need to look at spatial efficiency - outdoor metro cells are a part of that efficiency"

@stewartbaines: ALU: spectral efficiency can get 1.5x more capacity. Spatial efficiency can get 10x more capacity

@small_cells: we'll have an expanded number of nodes, as many as tens of thousands - and they could be anywhere

@small_cells: "but the box is probably the smallest part of the picture that needs to be solved"

@small_cells: "we have recognised just how important the beyond the box solution is"

@small_cells: "there's a large number of deployment challenges that need to be solved"

@small_cells: "ecosystem partners are likely to change, the whole value chain is up for grabs again"

@small_cells: "we need to talk about the box, I can't escape talking about the box"

@small_cells: it's important that the box is modular to meet the challenges of multiple deployments

@small_cells: "the box is in the public eye so we focussed on the look of the box"

@small_cells: "everything but the kitchen sink has to go into this box"

@small_cells: "you have to be careful about the design of the box, pay attention to details like heat dissipation"

@thinksmallcell: ALU 70% data traffic offload is the tipping point for commercial viability of a dedicated small cell carrier.

@thinksmallcell: ALU recapping that spatial efficiency (small cells) essential to meet forecast capacity growth of 25x

@stewartbaines: No silver bullet for metrocell backhaul. "I can't keep up" says Schnabel, ALU. Need every possible option

@thinksmallcell: ALU forecast 10x growth in cellsites for metro cells. OPEX more significant than CAPEX

@thinksmallcell: ALU explaining MetroDock - pluggable radio cards for compact metrocell. Is this the "radio blade server" for city lampposts?

@small_cells: "Backhaul : No silver bullet - requires comprehensive options"

@stewartbaines: If you can hang a Christmas light, can you really hang a metrocell?

@small_cells: "Site selection: no longer about RF positioning. Need to balance site availability, power, and backhaul"

@thinksmallcell: ALU claim to have automated design tool balancing RF location, backhaul and power for commercially viable best fit for#metrocells

@Alejandro_Avren: ALUH site acquisition major challenge for metrocell deployment..scramble has already begun

@small_cells: "what's not practical is to find an ideal site with no backhaul, that won't solve the problem"

@small_cells: "installation & commissioning a massive challenge, must design the product to make it easy to install without high-skilled labour"

@small_cells: "we have been going through and learning a tremendous amount of lessons with LightRadio"

@thinksmallcell: ALU saying they fully support X2 interface which would facilitate multivendor #HetNets

@small_cells: Next speaker : Will Franks CTO and co-founder of Ubiquisys

@small_cells: "smart cells is a hot topic in the industry"

@small_cells: "small cells serve 4 locations : Home : Enterprise : Urban : Rural "

@small_cells: "data wasn't the original driving factor it was voice quality and capacity"

@small_cells: "Now we are in the post data revolution era"

@small_cells: "we talk about metro cells on lampposts but 70% of mobile data is consumed indoors"

@stewartbaines: Ubiquisys: enterprises femtos are 1/4 cost of picos and DAS. Good news as most enterprises don't have DAS or picos due to cost

@small_cells: "rural backhaul is very costly, femto based technology with satellite backhaul speeds up rural deployment"

@small_cells: "small cells - a 7.7billion dollar opportunity!"

@small_cells: "one of the great things about metro indoor is there are a lot of sites - the real hotspots are indoor"

@small_cells: "50,000 public access small cells deployed - 200,000 open access femtocells deployed"

@Ubiquisys: Will Franks: Ubiquisys has 50k metro indoor small cells deployed around the world, mostly in Asia

@small_cells: "example Metro indoor hotspots stats: 90% of phones are smartphones : data to voice ratio is 10:1 : 10,000 data session in 24 hrs

@small_cells: "data dominated by chatty smartphone apps - signalling procedures per UE in busy hour - up to 50 users"

@Ubiquisys: Will Franks: traffic is dominated by data/signalling. Data is dominated by chatty smartphone apps. Users are highly transient.

@small_cells: "transient users - ave 7 mins in cell - different profile to wi-fi users who tend to dwell longer"

@small_cells: "cafe hotspot : people get their coffee and immediately fire up their browser or social network"

@small_cells: 'Map' of cafe hotspot cell usage shows data data data - lots of chatter but very little talking!

@Ubiquisys: Will Franks: small cells cover specific areas where traffic is heavily correlated

@small_cells: "challenges are not data use but cell overload, camp-on attempts, data vs signalling"

@small_cells: "our aim is zero touch deployment, making it as simple and as hands off as possible"

@Ubiquisys: Will Franks: The challenge for public access hotspots is no longer about headline data rates or call capacity

@small_cells: "hotspot robustness : these cells are 100% utilised in busy times and have to be able to manage themselves"

@small_cells: "smart cells are about extending the cloud to the edge of the network"

@small_cells: "why smart cells : it's about user experience"

@small_cells: "smart cells provide high-speed, short-range signal with low contention"

@small_cells: "Ubiquisys teamed up with Intel to put a comms-tuned compute platform in a small cell to make a smart cell"

@small_cells: "there are no standards issues with smart cells at all"

@Ubiquisys: Will Franks: Smart cells = small cell + hi spec server + clever apps

@small_cells: "proactive and predictive cache used to cut backhaul traffic - improves user experience"

@theshipster: Ubiquisys Will Franks: In Japan, small cells, with satellite backhaul, take rural coverage deployment time from 1 yr to 1 day

@small_cells: "more smart cell applications: cellular - wi-fi policy management : video / ad server : CDN clients : "

@Ubiquisys: With proactive smart cell caching, first play of a video plays from cloud, subsequent of same file play from cache

@small_cells: "small cells come in many flavours : home femtocells, enterprise small cells, metro indoor, metro outdoor and rural"

@Ubiquisys: Smart cells: optimise end UX, optimise backhaul performance, offer new edge cloud apps for service products

@MarcianoGilbert: Colt on stage promoting new business model managed femto services or How MVNO can distribute femto as a service

@Ubiquisys: Femto as a Service (FaaS) from a fixed service provider can accelerate deployment in buildings. Len Schuch of Colt

@small_cells: "enterprises have to embrace BYOD and Colt certainly are"

@Ubiquisys: FaaS opens the door for more mobile operators to deploy small cells

@small_cells: "demand and supply - don't believe the data crunch is a myth"

@small_cells: "near-time data growth has exceeded the value of last years Cisco VNI analysis"

@small_cells: "it's not just background data and email it is about delivering QoS"

@small_cells: "by 2016, 70% of data will be video"

@small_cells: "it's not 75kbps per sub spread over 6h it's 10Mbps per sub in 30s bursts"

@small_cells: "you can deliver high quality with low throughput but as soon as throughput increases you loose QoS"

@small_cells: "it's generally the backhaul which is the limit to throughout..."

@MarcianoGilbert: New thermodynamic demo on stage . After PV=NRT you have macro + small cell * hetnet = high QoS*high throughput

@Ubiquisys: Here's a slide visualising that smart cell proactive caching capability

@thinksmallcell: ip.access say X.2 interface isn't sufficient for purpose today. It needs to be for true multi vendor #HetNets

@small_cells: Speaker now is Hiroyuki Hosono Radio Access Network Development Dept at NTT DoCoMo

@small_cells: NTT DoCoMo already rolling out LTE products

@small_cells: by last March 30% Japanese population could access LTE, that'll be up to 70% by end of 2012!

@Alejandro_Avren: By end of 2012, NTT will cover 70% of population with LTE coverage

@small_cells: Japan will have almost total LTE coverage by end 2014

@small_cells: NTT DeCoMo have already signed up 2.2 million LTE subscribers and expect to hit 10m by end of 1q 2013.

@small_cells: "NTT DeCoMo see two main advantages for LTE femtocells : expanded coverage and traffic offload"

@small_cells: "approx 12 x data growth expected between 2011 & 2015 - we need to satisfy that future traffic demand"

@small_cells: "we will develop femtocell networks to help meet future data demand" NTT DeCoMo

@thinksmallcell: NTT DoCoMo forecast 12x mobile data traffic growth between 2011-2015. LTE #femtocells essential

@small_cells: "we may limit data speed of heavy users" NTT DeCoMo

@Alejandro_Avren: BH Telecom: more smart phones sold last year than PCs

@small_cells: "in 2011 more smartphones than PCs were sold"

@Ubiquisys: The number of smartphones sold exceeded PCs last year. In a few years the no of smartphones will dwarf PCs. #BHTelecom

@Ubiquisys: We are watching Adnan Hatalasevic talking about business solutions and synergy design for small cells and Wi-Fi

@small_cells: Next speaker Steve Price, Gen Manager, Comms and Infrastructure division, Intel

@small_cells: "I'd like to talk about building intelligence into the overall network"

@small_cells: watching a 'what happens in one internet minute video' ....http://techbullets.blogspot.co.uk/2012/06/internet-in-one-minute-intel.html



@small_cells: "mix of social networking and mobile users has changed the way we work and socialise. Now think ahead to 2015"

@stewartbaines: Here is that Intel internet minute infographic:

@small_cells: "what kind of network do we need for 2015 when there will be twice as many connected mobile devices as today?

@small_cells: "if done correctly you can increase revenue and decrease operating expenses"

@small_cells: "small cell base stations redefine HetNet economics"

@small_cells: "what is a smart cell? All small cells have some intelligence but now we are taking Intel's datacentre skills to the operator"

@small_cells: "the consumer with a mobile intelligent device can upload as much as he downloads, networks have to be symmetrical"

@small_cells: "we believe smart cells need massive storage abilities and high performance CPUs"

@small_cells: "smart small cells allow you to take advantage of value added services and offer better user experience"

@small_cells: "putting intelligence in a device increases cost, so we wanted to determine the economic benefits of smart small cells"

@small_cells: "we found there was a reduction in network operating costs of 22% when using smart cells, mainly from backhaul savings"

@Ubiquisys: Smart cells are more expensive than standard small cells, but fewer are needed to accomplish the same results @intel

@small_cells: "Summary business case findings: Improvements are seen in OpEx savings, specifically, in network OpEx"

@small_cells: "smart cells help with operator bottom line, beyond capacity and coverage"

@small_cells: "local caching and filtering eliminates peak hours overload"

@Ubiquisys: Conclusion: Smart Cells help with operator bottom line, beyond capacity and coverage @intel

@small_cells: we are in the midsts of a very exciting time in mobile comms - and the smart small cell is a key aspect of this revolution

@small_cells: "even Moore's law can't keep up with where the networks are going"

@small_cells: "silicon alone can't solve the thirst for bandwidth"

@Ubiquisys: Doug Pulley of @mindspeed is now talking about small cell architecture for RAN evolution

@small_cells: Next speaker : Doug Pulley - CTO Wireless, Wireless Business Unit - MindSpeed

@small_cells: "Small Cell Networks - Taking the strain - how many small cells to cover London - or the world!"

@small_cells: "Cell Traffic Dimensioning - what does it really take to overwhelm a cell?"

@small_cells: "internet video will be driving much of future mobile data traffic"

@small_cells: "is there a busy hour? most reports show traffic usage is fairly constant from 8-8"

@small_cells: "people are consuming data via multiple devices, my kids use three simultaneously - I don't know how they do it!"

@small_cells: Mindspeed's study suggests a London wide small cell network with over 71,000 base stations --- and 19 million needed worldwide!

@thinksmallcell: Mindspeed research study estimates global need for 19,059,612 small cells globally to meet Cisco VNI data traffic forecast

@small_cells: "all this detail helps specify and build the best small cell SoC solutions"

@small_cells: Next speaker is Viraj Abhayawardhana Specialist Strategy at BT talking about backhaul...

@small_cells: "BT provides fixed backhaul to all major mobile operators in the UK"

@small_cells: "BT Openzone has the biggest WiFi footprint in the UK. 16 wireless cities in the UK. 4 million UK hotspots"

@small_cells: "BT investing £2.5b extending fibre infrastructure close to home"

@small_cells: "Small Cells: How to identify sites, how to acquire sites, how to manage sites cost effectively, how to manage teams & field force

@small_cells: "street lamps came out top for small cell location"

@small_cells: "to reduce backhaul we must reuse as much capability as possible so we must try to leverage the fibre roll out"

@small_cells: "backhaul isn't just about access it's all about integrating, building an end to end OSS is a significant cost"

@SmallCell_Forum: BT: "Comedy and small cells: it's all about the timing"

@small_cells: "small cells have challenges in sites, backhaul and power - and costs have to come down"

@small_cells: "to solve backhaul problems, end to end service delivery and maintenance should be considered"

@Ubiquisys: Now in the conference room: OMA and @SmallCell_Forum cooperation - new enablers for new enhanced apps, from @telecomitaliaTw

@Ubiquisys: Digital use case at home: The Home wakes up and is aware of owners' presence, and gets adaptive to them! @telecomitaliaTw

@Ubiquisys: Shopping mall use case: Device tells you "Your favourite green ties today discounted" @telecomitaliaTw

@Ubiquisys: Now up at #SCWS2012, Yoav Volloch from @Broadcom: 3G/4G/5G multi RAT small cells

@Ubiquisys: Licensed vs Unlicensed: LTE enjoys better frequency bands, while Wi-Fi supports carrier aggregation @broadcom

@Ubiquisys: Broadcom believes a small cell is a multi RAT access point that manages the entire spectrum over a given cell range

@Ubiquisys: The business model for open access femtocells can be the same as ‘selling power to the grid’ @Broadcom

@Ubiquisys: Small cell solutions were born due to the practical need to increase 3G license spectrum capacity @broadcom

@Ubiquisys: Small cells are not low cost Macro cells; they have their own personality@Broadcom

@Ubiquisys: The final session of the day - a panel on new technologies reshaping the business case for small cells

@Ubiquisys: We get very hung up on presence + location aspect, but a valuable app is getting flat-rated local calls in coverage area

@stewartbaines: should enterprises get free at-desk mobile calls if they have a femto? And what of PBX integration?

@stewartbaines: Operators should think of the commercial value of presence & location from small cells

@Ubiquisys: @SmallCell_Forum asked consumers 'what apps would you pay for?’ Many were excited about having a home phone network

Day 3


@small_cells: First Speaker - Andy Sutton, Principal Network Engineer at Everything, Everywhere.

@small_cells: "small cells could be interpreted as anything non-macrocell"

@small_cells: "two different scenarios : capacity or coverage?"

@small_cells: "Femto provides in-building coverage for voice services"

@small_cells: "Public Access external small cells for capacity"

@small_cells: "we anticipate supporting voice as well as data on our public access small and pico cells"

@small_cells: "we're likely to see an improvement in spectral efficiency"

@small_cells: "if we deploy a 3g solution today we want to see an evolution path to LTE"

@small_cells: "on average we look at small cells costing 1/10th the cost of a macro"

@small_cells: "key performance indicators should ideally be the same as the macro network"

@small_cells: "you could open a new area of coverage and this is a different scenario to simply adding capacity to an existing hotspot"

@small_cells: "small cells are a game changer in terms of how we architect networks"

@small_cells: "both LoS and NLoS have a part to play in small cell backhaul"

@small_cells: "backhaul could be fully integrated with macro network or completely decoupled with an overlay (underlay) solution"

@small_cells: "we will see small cells rolled out in volume to support mobile network evolution"

@small_cells: "small cell sites must have a very low TCO in the region of 10% of that associated with macro sites"

@small_cells: "several backhaul solutions will be required to meet all likely deployment scenarios"

@small_cells: "reducing latency could be a significant battleground in the LTE market"

@small_cells: Yoshihito Shimazaki Deputy Division Head, from Softbank

@small_cells: Yoshito will talk to us about the status of LTE small cells

@small_cells: "in Japan data usage is crazy"

@thinksmallcell: everything everywhere say 3G metro cells will gain real traction during 2013. Expects dual carrier 3G before LTE

@small_cells: "What is the key to mobile market up-growth -- Market share : ARPU improvement : Market Value Improvement "

@small_cells: "four competition elements to win: 1 Network 2 service 3 charge rate 4 customer service "

@small_cells: "number of Softbank base stations: 190,000 -- excluding home femtocells"

@small_cells: "by May 2012 Softbank had deployed 121,850 home femtocells, the figure continues to rise"

@small_cells: very dense deployment of small cells in metropolitan Tokyo

@small_cells: "outdoor cell sites cannot cover all indoor areas in downtown Tokyo"

@small_cells: "femto to macro handover is very important to indoor"

@thinksmallcell: SoftBank almost completed trial of handover from inbuilding Femto to macrocell. Improved abnormal call drop rate by 3.5%

@small_cells: "we got the number one tv commercial by deploying the white dog"

@small_cells: "smartphone data traffic is 10X more than a feature phone"

@small_cells: "mobile network traffic will grow 12X from FY2010 to FY2016"

@small_cells: "Tokyo data use is very crazy, I can't believe it"

@stewartbaines: SoftBank: mobile distribution in Japan. Check out the Tokyo spike

@small_cells: "we are deploying a multi-layer cell architecture"

@small_cells: "we need a very strong co-operative interface coordination"

@small_cells: current speaker : Jang Ahn Kwon Chief Marketing Officer & VP, Contela Inc.

@thinksmallcell: korea has >50% smartphones, 7M LTE subs today, 14M by end 2012. Competition is fierce

@thinksmallcell: LTE congestion in Korea came sooner than expected

@small_cells: "home small cell needs to be dual mode to support 3G and LTE for legacy handsets"

@thinksmallcell: Korea residential femtocells need to be dual mode 3G and LTE say Contela. Not everyone in a family will have LTE handsets

@thinksmallcell: Contela achieved 60Mbps downlink and 25Mbps uplink performance on their LTE femtocell field trials

@small_cells: Current speaker : Jie Zhang - Ranplan "small cell deployment in heterogeneous networks"

@small_cells: Fascinating coverage mapping slides from Jie Zhang - graphically illustrating coverage benefits of small cell deployment

@small_cells: "Intelligent Cell Optimisation (ICO) shows where small cells should be located"

@disruptivedean: After listening to comments at #SCWS2012 , I think that some forms of carrier WiFi will make sense outdoors. But indoor proposition trickier

@small_cells: it seems European homes are better at blocking mobile signals that US homes...

@small_cells: "providing better coverage throughout the entire home gets the whole family on the operator's plan"

@small_cells: "does it work? does it really offer long lasting value to the subscriber and operator"

@small_cells: current speaker is "Michiel Lotter, VP of Engineering Nextivity Inc.

@small_cells: "95% of customers who installed cel-fi remained with operator (as opposed to churning away)"

@small_cells: "50% of mobile users worldwide don't have access to broadband, meaning femtos are not an option"

@small_cells: Next speaker: Andy Germano Vice Chairman Small cell Forum

@small_cells: "why small cell service? 5 bar indoor coverage"

@small_cells: "small cells allow for application sweetspot"

@small_cells: "small cells can help deliver the intelligent home"

@small_cells: "small cell networks can help deliver location based services"

@small_cells: "small cells enable shopping 2.0"

@small_cells: "8 different demos of small cell enabled apps going on at recent small cell forum"

@small_cells: "consumers want small cell services and are willing to pay"

@Alejandro_Avren: Sunrise Switzerland now on the main stage, presenting their project status on their femtocell deployment

@small_cells: "Sunrise is under pressure to constantly add capacity, enhance the user experience, & keep a lid on total cost of ownership"

@Alejandro_Avren: Sunrise: 16 time data usage increase expected by 2017, doubling every year until 2014!!

@small_cells: "avoid problems- avoid low price users eating up too much capacity : maximise utilisation of spectrum : deploy smart wi-fi offload

@small_cells: "the congested 3g cell rate is increasing whereas the footprint of the congested cells remains the same"

@small_cells: "demanding environmental factors in Switzerland will favour the use of small cells"

@small_cells: "Sunrise will continue to use the femto and is ready for wide-spread deployment"

@small_cells: "main purpose: to deliver cost efficient object special coverage to compliment macro base station portfolio"

@small_cells: Sunrise will "continue to use femto as a retention and business enabler tool"

@small_cells: "fair use policies reduce levels of data use growth temporarily but they cannot reverse the skyrocketing demand for mobile data"

@small_cells: "small cells vendors need to support SON for HetNet as well as an effective small cells management"

@small_cells: next speaker: Jean-Christophe Nanan, RF systems engineer at Freescale - small cells call for scaleable architecture

@small_cells: Final speaker is Joseph Byre Analyst at the Linley Group

@small_cells: "Mobile bandwidth is increasing"

@small_cells: UK is depressingly blue on a map showing LTE enabled areas in red :0(

@small_cells: "funding for bandwidth increases and alternatives is decreasing, pressuring OEMs and Chip Cos."

@small_cells: "ARPU rising only 3%"

@small_cells: "Base station costs falling from $40K"

@small_cells: "Moore's Law enables cost reduction but heats up competition among chip companies"

@small_cells: "to defend or capture share, chip companies are rushing in to supply base station processors"

@small_cells: "the opportunity for system vendors is an opportunity for chip factors"

@small_cells: "markets tend to ramp later than expected but ramps tend to be bigger than forecast"

@small_cells: "market drivers for femtocells are problematical"

@small_cells: "shipment growth has only just begun - enough data to define a trend?"

@small_cells: "vague plans by major operators to deploy"

@small_cells: "causes for concern - technology dynamics: ..."

@thinksmallcell: NEC's outdoor metrocell. Looks pretty solid and durable to me. Believed to be Ubiquisys technology inside.
