Different Types of RAN Architectures - Distributed, Centralized & Cloud


I come across a question relating to the different type of RAN architectures once per month on an average. Even though we have covered the topic as part of some or the other tutorial, we decided to do a dedicated tutorial on this.

The video and slides are embedded below

As always, feedback and comments welcome.

From traditional RAN to Open RAN - O-RAN: Goals and Challenges


My Open RAN tutorial has recently gained popularity with recent announcements from Altiostar, Mavenir, Parallel Wireless, Telefonica and Vodafone. With TIP Summit in few weeks time, I am hoping for a lot more curious people to discover that blog post and video.

Olivier Simon, Director, Radio Innovation, Orange spoke about "O-RAN: Goals and Challenges" at Open Networking Summit Europe 2019. In his presentation, he explained how O-RAN will trigger more intelligence and openness in the RAN domain. He talked about which use cases will require this new architecture and why O-RAN is coming at the right time. Major architectural change are necessary in the next years in order to improve E2E latency and benefit from the flexibility of virtualized network functions. O-RAN will provide the right framework in order to perform this transformation in an open manner and keeping at the same time economies of scale thanks to a global adoption.


The presentation also touches on O-RAN Software Community. The O-RAN Alliance recently partnered with the Linux Foundation to establish the O-RAN-Software Community (O-RAN-SC), to provide that open source software application layer to the RAN. O-RAN-SC will foster development of an open source infrastructure platform for running 5G RAN solutions.

The key aspects of ORAN-SC are:
  • New Open Community focused on RAN Software in collaboration with O-RAN Alliance
  • Set up for collaboration across OPNFV, ONAP, Akraino and other Open Source projects

Here is the video of the conference embedded below:

When will 2G & 3G be switched off now that 5G is here?


I wrote this blog post '2G / 3G Switch Off: A Tale of Two Worlds' back in Oct 2017. Since then I have continued to see the same trend in 2G/3G shutdown announcements. Based on that post and also taking the GSMA Mobile Economy Report into account, we have created a short tutorial on 2G/3G switch off and how the trends are affected by the launch of KaiOS based Smart Feature phones. Presentation and video embedded below. Would love to hear your thoughts.

Drones at Mobile World Congress 2019 and my upcoming webinar on 5G at #MWC19


Mobile World Congress featured many different drones for many different purposes and applications. While I wouldn't claim to have seen all or even most of them, I managed to go to the GSMA seminar 'The Internet of the Skies – Connecting Drones'. Key topics of the seminar included:

  • The support of safe BVLOS (Beyond Visual Line Of Sight) and autonomous operation of unmanned aircraft (UA)
  • The use of mobile connectivity to enhance the efficiency and effectiveness of UA, by enabling BVLOS operation, supporting real-time data transmissions from on-board cameras and sensors
  • Mobile connectivity requirements for registration and identification, flight planning and approval, the transmission of meteorological information, geo-fencing, geo-caging and tracking

The best thing is that the presentations are available for anyone interested. Link at the bottom of this post. I have embedded some videos from the seminar in the playlist as well.


During the seminar, Telefônica talked about their fire fighting Antifire drones which are helping detect, survey and combat fires before, during and after a fire breaks out.


Turkcell talked about their Dronecell. The 5G connected drone can be used for many different purposes from inspection, photos and videos to providing temporary coverage in case of disasters. One of the interesting use cases was also surveillance (see video). They are also working with a local drone company, see here. For Dronecell they are testing with different vendors like Huawei, Airspan, etc. and also have their own hardware (see pic above).


The Latvian mobile operator Mans LMT talked about how Drones in combination with Sensors and AI can provide endless opportunities. In addition drones can also be used for delivering goods and rescue missions. Finally, LMT with Lufthansa Systems are working on a mobile, connected UTM platform for drone solutions and traffic management (see video below).



In addition enjoyed a virtual ride in Ooredoo’s 5G-enabled Aerial Taxi. Also happened to bump into Robert Joyce who used to work for Telefonica O2 UK and used to be very active in O2's small cells rollout during 2012 London Olympics. See here, here & here.

Huawei showed SkySite: A Drone with 5G base station & '5G Book' RRU. I blogged about it here.

Saudi Telecom Company (STC) had a drone flight simulator. I didn't see it but tweet below


There were 10 Catalonian companies showing smart drones. Tweet below



Finally, Samsung Electronics, Cisco and Orange unveiled "A Drone carrying a very low latency, high-quality video system is piloted from the Orange booth at the Fira de Barcelona. The drone, which is located outdoors at an Orange datacenter, carries a 5G router (CPE) that is used to transfer commands to the drone and transmit a high-quality video feed with low latency. At the Orange booth, the pilot can be seen controlling the drone by using a 5G tablet. Aeromedia, a leading drone operator, collaborated in this demo." Sadly, I didn't manage to find this and couldn't see any videos either.


Here is a video playlist of Drones from MWC.






I am also running a webinar next week looking at 5G @ MWC 2019 on behalf of Parallel Wireless (#PWTechTrain) . Along with drones, I plan to talk about lot more things. Register here.

LoRa is quietly marching on...


During the mobile world congress, I was pleasantly surprised to see how LoRa ecosystem keeps getting larger. There was also an upbeat mood within the LoRa vendor community as it keeps winning one battle after another. Here is my short take on the technology with an unbiased lens.


To start with, lets look at this short report by Tom Rebbeck from Analysys Mason. The PDF can be downloaded after registering from here.

As can be seen, all major IoT technologies (LoRa, NB-IoT, Sigfox & LTE-M) gained ground in 2017. Most of the LoRa and all of Sigfox networks are actually not deployed by the mobile operators. From the article:

These points lead to a final observation about network deployments – many operators are launching multiple technologies. Of the 26 operators with publicly-announced interest in LTE-M networks, 20 also have plans for other networks;
• 14 will combine it with NB-IoT
• four will offer LTE-M and LoRa and
• two, Softbank and Swisscom, are working with LoRa, LTE-M and NB-IoT.

We are not aware of operators also owning Sigfox networks, though some, such as Telefónica, are selling connectivity provided by a Sigfox network operator.

The incremental cost of upgrading from NB-IoT or LTE-M to both technologies is relatively small. Most estimates put the additional cost at less than an additional 20% – and sometimes considerably less. For many operators, the question will be which technology to prioritise, and when to launch, rather than which to choose.

The reasons for launching multiple networks appear to be tactical as much as strategic. Some operators firmly believe that the different technologies will match different use cases – for example, LoRa may be better suited to stationary, low bandwidth devices like smart meters, while LTE-M, could meet the needs of devices that need mobility, higher bandwidth and support for voice, for example a personal health monitor with an emergency call button.

But, a fundamental motive for offering multiple networks is to hedge investments. While they may not admit it publicly, operators do not know which technology will gain the most traction. They do not want to lose significant, lucrative contracts because they have backed the wrong technology. Deploying both LTE-M and NB-IoT – or LoRa – adds little cost and yet provides a hedge against this risk. For operators launching LoRa, there has been the added benefit of being early to market and gaining experience of what developers want and need from LPWA networks. This experience should help them when other technologies are deployed at scale.

The following is from MWC 2018 summary by ABI Research:

LPWA network technologies continue to gather momentum with adoption from a growing ecosystem of communications service providers (CSPs), original equipment manufacturers (OEMs) and IoT solution providers. LPWA networks are central to the connectivity offerings from telcos with support for NB-IoT, LTE-M, LoRaWAN, and SIGFOX. Telefonica highlighted SIGFOX as an important network technology along with NB-IoT and Cat M in its IoT connectivity platform. Similarly, Orange and SK Telecom emphasized on their continued support for LoRaWAN along with Cat M in France and South Korea. On the other hand, Vodafone and Deutsche Telekom, while aggressively pursuing deployment of NB-IoT networks, currently have mostly large scale POCs on their networks. 

...
Smart meters — Utilities are demanding that meter OEMs and technology solution providers deliver product design life of at least 15 years for battery operated smart water and gas meters. LPWA technologies, such as NB-IoT, LoRaWAN, SIGFOX and wireless M-bus, that are optimized for very low-power consumption and available at low cost are clearly emerging as the most favored LPWA solutions.

The following picture is from Ovum post MWC-2018 Webinar:

Here is a short video from MWC by yours truly looking at LoRa Gateways


There are also few announcements / news from LoRa world just to highlight how the ecosystem is thriving:


Source: SenRa

So someone recently asked me is LoRa is the new WiMax? The answer is obviously a big NO. Just look at the LoRa alliance members in the picture above. Its a whole ecosystem with different players having different interests, working on a different part of the ecosystem.

NB-IoT & LTE-M will gain ground in the coming years but there will always be a place for other LPWA technologies like LoRa.

Finally, here is a slide deck (embedded below) that I really like. The picture above very nicely illustrates that LoRaWAN and Cellular complement each other well. Maybe that is the reason that Orange is a big supporter of LoRa.



So for operators who are just starting their IoT journey or smaller operators who are unsure of the IoT potential, may want to start their journey with LoRa to play around and understand the business cases, etc. In the meantime LTE-M and NB-IoT ecosystem will mature with prices coming down further and battery time improving. That may be the right time to decide on the way forward.

Quick summary of Mobile World Congress 2018 (#MWC18)


This year at MWC, I took the time out to go and see as many companies as I can. My main focus was looking at connectivity solutions, infrastructure, devices, gadgets and anything else cool. I have to say that I wasn't too impressed. I found some of the things later on Twitter or YouTube but as it happens, one cannot see everything.

I will be writing a blog on Small Cells, Infrastructure, etc. later on but here are some cool videos that I have found. As its a playlist, if I find any more, it will be added to the same playlist below.



The big vendors did not open up their stands for everyone (even I couldn't get in 😉) but the good news is that most of their demos is available online. Below are the name of the companies that had official MWC 2018 websites. Will add more when I find them.

Operators

Network Equipment Vendors

3GPP Sidelink and its proposed extensions

In an earlier post I discussed briefly about the sidelink: V2V communications are based on D2D communications defined as part of ProSe services in Release 12 and Release 13 of the specification. As part of ProSe services, a new D2D interface (designated as PC5, also known as sidelink at the physical layer) was introduced and now as part of the V2V WI it has been enhanced for vehicular use cases, specifically addressing high speed (up to 250Kph) and high density (thousands of nodes).

Before going further, lets just quickly recap the different V2x abbreviations:

  • V2X = Vehicle-to-Everything
  • V2V = Vehicle-to-Vehicle
  • V2I = Vehicle-to-Infrastructure 
  • V2P = Vehicle-to-Pedestrian 
  • V2H = Vehicle-to-Home
  • eV2X = enhanced Vehicle-to-Everything

I came across this interesting presentation from ITRI that provides lot more details on sidelink and its proposed extension to other topics including eV2X and FeD2D (Further enhanced Device-to-Device).

There are quite a few references in the document that provides more details on sidelink and its operation and extension to other devices like wearables.


There are also details on synchronization and eV2X services.

There is also a very nice D2D overview presentation by Orange that I am embedding below (download from slideshare)

Variety of 3GPP IoT technologies and Market Status - May 2017



I have seen many people wondering if so many different types of IoT technologies are needed, 3GPP or otherwise. The story behind that is that for many years 3GPP did not focus too much on creating an IoT variant of the standards. Their hope was that users will make use of LTE Cat 1 for IoT and then later on they created LTE Cat 0 (see here and here).

The problem with this approach was that the market was ripe for a solution to a different types of IoT technologies that 3GPP could not satisfy. The table below is just an indication of the different types of technologies, but there are many others not listed in here.


The most popular IoT (or M2M) technology to date is the humble 2G GSM/GPRS. Couple of weeks back Vodafone announced that it has reached a milestone of 50 million IoT connections worldwide. They are also adding roughly 1 million new connections every month. The majority of these are GSM/GPRS.

Different operators have been assessing their strategy for IoT devices. Some operators have either switched off or are planning to switch off they 2G networks. Others have a long term plan for 2G networks and would rather switch off their 3G networks to refarm the spectrum to more efficient 4G. A small chunk of 2G on the other hand would be a good option for voice & existing IoT devices with small amount of data transfer.

In fact this is one of the reasons that in Release-13 GSM is being enhanced for IoT. This new version is known as Extended Coverage – GSM – Internet of Things (EC-GSM-IoT ). According to GSMA, "It is based on eGPRS and designed as a high capacity, long range, low energy and low complexity cellular system for IoT communications. The optimisations made in EC-GSM-IoT that need to be made to existing GSM networks can be made as a software upgrade, ensuring coverage and accelerated time to-market. Battery life of up to 10 years can be supported for a wide range use cases."

The most popular of the non-3GPP IoT technologies are Sigfox and LoRa. Both these technologies have gained significant ground and many backers in the market. This, along with the gap in the market and the need for low power IoT technologies that transfer just a little amount of data and has a long battery life motivated 3GPP to create new IoT technologies that were standardised as part of Rel-13 and are being further enhanced in Rel-14. A summary of these technologies can be seen below


If you look at the first picture on the top (modified from Qualcomm's original here), you will see that these different IoT technologies, 3GPP or otherwise address different needs. No wonder many operators are using the unlicensed LPWA IoT technologies as a starting point, hoping to complement them by 3GPP technologies when ready.

Finally, looks like there is a difference in understanding of standards between Ericsson and Huawei and as a result their implementation is incompatible. Hopefully this will be sorted out soon.


Market Status:

Telefonica has publicly said that Sigfox is the best way forward for the time being. No news about any 3GPP IoT technologies.

Orange has rolled out LoRa network but has said that when NB-IoT is ready, they will switch the customers on to that.

KPN deployed LoRa throughout the Netherlands thereby making it the first country across the world with complete coverage. Haven't ruled out NB-IoT when available.

SK Telecom completed nationwide LoRa IoT network deployment in South Korea last year. It sees LTE-M and LoRa as Its 'Two Main IoT Pillars'.

Deutsche Telekom has rolled out NarrowBand-IoT (NB-IoT) Network across eight countries in Europe (Germany, the Netherlands, Greece, Poland, Hungary, Austria, Slovakia, Croatia)

Vodafone is fully committed to NB-IoT. Their network is already operational in Spain and will be launching in Ireland and Netherlands later on this year.

Telecom Italia is in process of launching NB-IoT. Water meters in Turin are already sending their readings using NB-IoT.

China Telecom, in conjunction with Shenzhen Water and Huawei launched 'World's First' Commercial NB-IoT-based Smart Water Project on World Water Day.

SoftBank is deploying LTE-M (Cat-M1) and NB-IoT networks nationwide, powered by Ericsson.

Orange Belgium plans to roll-out nationwide NB-IoT & LTE-M IoT Networks in 2017

China Mobile is committed to 3GPP based IoT technologies. It has conducted outdoor trials of NB-IoT with Huawei and ZTE and is also trialing LTE-M with Ericsson and Qualcomm.

Verizon has launched Industry’s first LTE-M Nationwide IoT Network.

AT&T will be launching LTE-M network later on this year in US as well as Mexico.

Sprint said it plans to deploy LTE Cat 1 technology in support of the Internet of Things (IoT) across its network by the end of July.

Whats up with VoLTE Roaming?

I have been covering the LTE Voice Summit for last couple of years (see here: 2015 & 2014) but this year I wont be around unfortunately. Anyway, I am sure there will be many interesting discussions. From my point of view, the 2 topics that have been widely discussed is roaming and VoWiFi.

One of the criticisms of VoWiFi is that it does not the QoS aspect is missing, which makes VoLTE special. In a recent post, I looked at the QoS in VoWiFi issue. If you haven't seen it, see here.

Coming back to VoLTE roaming, I came across this recent presentation by Orange.
This suggests that S8HR is a bad idea, the focus should be on LBO. For anyone who is not aware of the details of S8HR & LBO, please see my earlier blog post here. What this presentation suggests is to use LBO with no MTR (Mobile Termination Rates) but instead use TAP (Transferred Account Procedures). The presentation is embedded below:



Another approach that is not discussed too much but seems to be the norm at the moment is the use of IP eXchange (IPX). I also came across this other panel discussion on the topic


IPX is already in use for data roaming today and acts as a hub between different operators helping to solve inter-operability issues and mediating between roaming models. It can work out based on the calling and callee party what kind of quality and approach to use.

Here is the summary of the panel discussion:



Hopefully the LTE Voice Summit next week will provide some more insights. I look forward to hearing them.

Updates from the 3GPP RAN 5G Workshop - Part 1

3GPP held a 5G Workshop in Phoenix last week. 550 delegates and over 70 presentations contributed to the discussion, which covered the full range of requirements that will feed TSG RAN work items for the next five years. I will eventually look at all the presentations and highlight the ones that I find interesting as a part of this blog. Due to the vast number of presentations, I will split them into a few blog posts.

Lets start with the chairman summary. The chair highlighted three high level use cases that 5G needs to address (This has been highlighted in many presentations, see here for example):
  • Enhanced Mobile Broadbandare 
  • Massive Machine Type Communications
  • Ultra-reliable and Low Latency Communications
As can be seen in the picture above, 3GPP is planning to split the 5G work into two phases. Phase 1 (Rel-15) will look at a subset of requirements that are important for the commercial needs of the day. Phase 2 (Rel-16) will look at more features, use cases, detailed requirements, etc.

Here is the chair summary of the workshop:




The presentation (RWS-150002) from Motorola/Lenovo highlighted the need to handle different spectrum. For sub-6GHz, the existing air interface could work with slight modifications. For spectrum between 6GHz and 30GHz, again a similar air interface like 4G may be good enough but for above 30GHz, there is a need for new one die to phase noise.

The presentation by CATT or China Academy of Telecommunication Technology (RWS-150003) is quite interesting and is embedded below. They also propose Pattern Division Multiple Access (PDMA).




Orange (RWS-150004) has definitely put a thought into what good 5G would be. Their presentation is embedded below too:




The presentation from Huawei (RWS-150006) introduced the concept of Unified Air Interface, UAI.



They presentation also explains the concept of Adaptive Frame structures and RAN slicing very well. For those who may be wondering, uMTC stands for ultra-reliable MTC and mMTC stands for massive MTC. RAN slicing enables the RAN to be partitioned such that a certain amount of carriers are always dedicated to a certain services independently of other services. This ensures that the service in the slice is always served reliably.

The final presentation is the vision and priorities by 5GPPP as follows:

Voice over WiFi (VoWiFi) technical details

VoWiFi is certainly a hot topic, thanks to the support of VoWiFi on iPhone 6. A presentation from LTE World Summit 2014 by Taqua on this topic has already crossed 13K views. In this post I intend to look at the different approaches for VoWiFi and throw in some technical details. I am by no means an expert so please feel free to add your input in the comments.

Anybody reading this post is not aware of S2a, S2b, Samog, TWAG, ePDG, etc. and what they are, please refer to our whitepaper on cellular and wi-fi integration here (section 3).

There are two approaches to VoWiFi, native client already in your device or an App that could be either downloaded from the app store or pre-installed. The UK operator '3' has an app known as ThreeInTouch. While on WiFi, this app can make and receive calls and texts. The only problem is that it does not handover an ongoing call from WiFi to cellular and and vice versa. Here are a few slides (slides 36-38) from them from a conference last year:



The other operators have a native client that can use Wi-Fi as the access network for voice calls as well as the data when the device is connected on the WLAN.

A simple architecture can be seen from the picture above. As can be seen, the device can connect to the network via a non-3GPP trusted wireless access network via the TWAG or via a non-3GPP untrusted wireless access network via ePDG. In the latter case, an IPSec tunnel would have to be established between the device and the ePDG. The SIM credentials would be used for authentication purposes so that an intruder cannot access ePDG and the core.

Now, I dont want to talk about VoLTE bearers establishment, etc. which I have already done here earlier. In order to establish S2a (trusted) and S2b (untrusted) connection, the AAA server selects an APN among those which are subscribed to in the HLR/HSS. The PDN-GW (generally referred to as PGW) dynamically assigns an IP address out of a pool of addresses which is associated with this APN. This UE IP address is used by the VoWiFi SIP UA (User Agent) as the contact information when registering to the SIP soft switch (which would typically be the operators IMS network).

If for any reason the SIP UA in the device is not able to use the SIM for authentication (needs ISIM?) then a username/password based authentication credentials can be used (SIP digest authentication).

Typically, there would be a seperate UA for VoLTE and VoWiFi. They would both be generally registering to the same IMS APN using different credentials and contact addresses. The IMS network can deal with multiple registrations from the same subscriber but from different IP addresses (see 3GPP TS 23.237 - 'IMS Service Continuity' for details).

Because of multiple UA's, a new element needs to be introduced in order to 'fork' the downstream media streams (RTP/RTCP packets) to different IP addresses over time.

3GPP has defined the Access Transfer Gateway (ATGW) which is controlled by the Access Transfer Control Function (ATCF); the ATCF interfaces to the IMS and Service Centralization and Continuity Application Server (SCC AS). All these are not shown in the picture above but is available in 3GPP TS 23.237. The IMS networks in use today as well as the one being deployed for VoLTE does not have ATGW/ATCF. As a result vendors have to come up with clever non-standardised solutions to solve the problem.

When there is a handover between 3GPP and non-3GPP networks, the UE IP address needs to be preserved. Solutions like MIP and IPSec have been used in the past but they are not flexible. The Release-12 solution of eSAMOG (see 3GPP TS 23.402) can be used but the solution requires changes in the UE. For the time being we will see proprietary solutions only but hopefully in future there would be standardised solutions available.

3GPP TS 23.234 describes more in detail the interworking of 3GPP based system and WLAN. Interested readers can refer to that for further insight.

UK: Spectrum, Operators, Vendors and LTE

So LTE (or '4G') is about to be launched in the UK as announced yesterday. Its going to be branded as 4GEE.

Here is a summary of the Spectrum in the UK that will be used for LTE and would be auctioned by Ofcom.


Here is the current allocation of Spectrum in the UK

The above pics are from a presentation by Ofcom in LTE World Summit 2012 in Barcelona, available here.



The last table is from an Ofcom document here. Its very interesting read. For example I didnt know that The L-band was the first major part of Ofcom spectrum awards programme relevant to mobile services. It consists of 40MHz between 1452MHz and 1492MHz. The auction took place in May 2008, in which Qualcomm won the entirety of the available spectrum.

Here is the summary of the operators working on LTE:


Everything Everywhere (EE = Orange + T-Mobile) - They are calling their '4G' service as EE, covering up to 70% of the UK by the end of 2013. Network kit provided by Huawei.

Three - Samsung will provide the Radio Access Network, and the core infrastructure, for Three's LTE (4G) network. That includes the base stations, and radio core. 3 UK has agreed to purchase 2 x 15 MHz of 1800 MHz spectrum from Everything everywhere, and plans commercial launch of LTE service in 2013.

Telefonica (O2) trial network - Equipment supplied by Nokia Siemens Networks (NSN) for both the Radio and Core network elements. Backhaul for the 4G trial network has been provided using Microwave Radio Equipment from Cambridge Broadband Networks Limited, NEC and Nokia Siemens Networks.

Updated 13/09/12 - 11:25

UK Broadband rolled out the first commercial TD-LTE network in London back in February (available to customers since May 2012). The equipment is provided by Huawei. They have 40MHz in Band 42 (3.5GHz) and 84MHz in band 43 (3.6GHz).

Vodafone - No news.

A quick summary of #SCWS2012 in tweets

Summary of the interesting announcements and things that happened in the Small Cells World Summit 2012

DAY 1

@lesanto: "small cells are seen as a viable option to meet the demands of exponentially growing networks". even Mongolia is getting into the small cells!

@lesanto: First keynote speaker is Simon Saunders chairman of the Small Cell forum (he's written a LOT of books on the subject...)





@lesanto: I will be quoting Simon Saunders in this style: SS "this is the premier Small Cells event in the world"

@lesanto: SS "the agenda over the next few days is effectively a guide to all the Small Cells issues - a well balanced program"

@lesanto: SS "people often ask which Small Cells event they should go to. I say this one, if you can only do one industry this is it"

@lesanto: Simon Saunders "why is it that Small Cells are a good idea in the first place?"

@lesanto: SS "the more we try to serve the unlimited demand for data with macro cells the more interference we have to deal with"

@lesanto: SS "Small Cell networks help us to serve those data demands without increasing interference"

@lesanto: SS "we founded the Femto Forum in 2007 to answer these challenges"

@lesanto: SS "through hard work we achieved an open architecture for the 3G Femtocells. We highlighted a business case for Femtocells"

@stewartbaines: Simon Saunders: Capacity at limits, pushing Shannon's Law. We need more cells, tighter interference control and cost control

@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:



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

@Ubiquisys: #SCWS2012 in pictures http://ubiquisys.com/small-cells-blog/small-cells-world-summit-2012-in-pictures/ - Is that you I see?

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.
