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.

MWC Summary from other Analysts:

LTE-Broadcast making a push while Terrestrial broadcast still popular as ever

"TV isn't dying, it's having babies." This quote made my day. I have argued a few times in the past that terrestrial broadcasting will continue working and will be probably the most popular approach for a long time to come. The way things work with it may change. Multi-screen is one possible approach but you may have more interactions like 'red button functionality', etc.
Anyway, in Europe 800MHz spectrum has been cleared for use by Mobile Broadband technologies (LTE mainly). 700MHz is planned to be cleared as well by 2020, as per the suggestion in Lamy report. The other UHF band from 470MHz to 694MHz would be left as it is until 2030, with a review planned in 2025.

This has forced even big players like BBC to start looking at other mechanisms to deliver TV. While BBC3 was moved to online only, BBC is also exploring how to use LTE-Multicast to deliver content. It has been working to have its very popular iPlayer work with eMBMS.

Embedded below is a presentation from Cambridge Wireless CWTEC 2015 conference.

eMBMS is gaining popularity with its presence in lot more chipsets and even more trials. GSA report has shown that there are quite a few trials going on worldwide but the question remains about the business models. Most operators would not like to become content providers and compete with the incumbents in their markets. Having someone like BBC in the UK is helpful but not sure how many such options are available worldwide. Embedded below is the GSA presentation

There were some nice pictures from MWC as can be seen above. Ericsson has a video as well (below) on how the app works.

D-Link is also working on M2M modules that could be used in billboards to dynamically update the ads at very regular intervals. There is a video here that explains this further.

Finally here is a Video from Visteon/Verizon that explains how LTE-Multicast can be used to deliver software updates in the connected car:

Finally, here are couple of presentations that may interest you too:

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.

Mobile World Congress 2014 (#MWC14) Roundups

The worlds largest technology event came to a conclusion just over a week back so here is a summary of reports and roundups written by different people. Feel free to add yours in the comments:

The best way is to start with this Video of different gadgets by Orange (excuse their adverts)

Maravedis-Rethink has an excellent summary from Network point of view:

Now all the carriers have the same devices, and the all-you-can-eat offers are largely gone. This has shifted the competitive race to innovation in pricing and bundling; to services, even over-the-top ones; but most importantly to the one area which is still unique to MNOs, their licensed-spectrum networks. The race to implement more and more advanced features from the 3GPP menu is not just a carrier game of ‘mine’s bigger than yours’, but a truly necessary attempt, at least in the developed mobile markets, to differentiate themselves with the most advanced network capacity and capabilities.

In the network, new battle lines are being drawn, and the players are placing big bets on unproven technologies and new architectures. This is taking place on two levels – the well-understood but highly complex advances in RAN platforms, from the LTE-Advanced standards to small cells to Cloud-RAN; and the shift towards software-driven, if not yet fully software-defined networking, and towards virtualization.

Complete summary here.

Chetan Sharma has written a brilliant summary and covers all different topics:

All the progress that has been on the mobile economy has been on the back of trillions of dollars of investment over the last couple of decades. With declining margins, how long do operators continue to invest and at what pace? What’s the margin profile they are willing to live with? What’s the role of government in building out the infrastructure when high-speed mobile networks are concerned? Japan, Korea, Israel have all based their competitiveness on connected broadband world. Can others follow? The impact of Whatsapp launching voice services and Netflix/Comcast deal were hotly debated in the hallways. It is one thing to put out national broadband plans and it is entirely another reality to have an execution path to deliver on the plan. The broadband investment has much far reaching implications than most people and governments realize.

Complete article here.

Ian Poole from Radio Electronics has done a good job too with the summary and video:

There was a considerable amount of talk about connected cities, connected cars and the like. Many exhibitors at Mobile World Congress were showing their ideas and developments. There is a huge amount of work going on in these areas and this is reflected in the work and products being exhibited.
Said Mike Short, VP Telefonica: “Mobile World Congress is more of a data World Congress . . . . . . . there are many software companies, many special network companies, other companies providing billing and customer care and there are solutions for the whole digital economy”
Talking to a variety of people across Mobile World Congress, it was obvious there is a large amount of work going on.
In terms of the auto mobile industry there is a lot of interest and development. While it is not expected all of the work will come to fruition in the short term, such as mesh networked cars where the networking elements can be used for crash avoidance, etc, there are other areas for in car connectivity that will be implemented in the shorter term.
Qualcomm were even demonstrating an electric racing car that not only used wireless communications technology, but also utilised wireless charging. In this way they were incorporating two developing technologies.
In addition to this, technologies like Weightless – the white space data cellular system have moved forwards. The original aim was for the technology to be used in the television white space to provide low powered data communications particularly for remote sensors and actuators. For these applications, cellular technology is too heavy. Dealing with complex waveforms like OFDM requires considerable processing and this is not conducive to long battery life – some devices ae expected to operate for months or even years from the same battery.
Neul has been working to develop the ideas further. They are now looking at using unlicensed spectrum instead of the TV white space. They have found that in urban areas, little white space often exists. Unfortunately it is often in urban environments where population levels are highest and there will be the greatest need for low power data communications.
In another move announced at Mobile World Congress Orange announced that it is helping start up companies who are developing products for the IoT. Orange states that it wants to help them accelerate development and assist with marketing. This move is possibly a long term move, because it can only be approached with 4G, but with 5G anticipated to be more capable of meeting IoT requirements it should be able to enter the market more strongly when it arrives. It is anticipated that the main areas where IoT will start to grow initially are personal services, healthcare, the connected home and smart cities.
Complete report and the video here.

Finally, an excellent summary on Small Cells and related by ThinkSmallCell:

The official Small Cell conference track was pretty tame - Vodafone have deployed 300K Small Cells in total, KT (Korea Telecom) and Radisys spoke of 18K LTE deployed in mostly indoor metropolitan areas. Vodafone said they continue to drive vendors to deliver multi-technology small cell and backhaul products with high operational efficiency and look for added value to help the business case. By contrast, the Small Cell Forum booth hosted extensive and popular presentations and is perhaps outgrowing its booth format.
A key network equipment vendor theme was SDN (Software Defined Network) and NFV (Network Function Virtualisation). We can expect next year to see this evolving to orchestration - better methods of managing and manipulating these virtualised software components, but in the short term it means slightly less or cheaper hardware. Frankly, I was more impressed to see Huawei now supporting any of 2G, 3G or LTE (FDD&TDD) on the same physical macrocell radio hardware modules - true software definable radio. We are beginning to see that capability for Small Cells too, but it's not quite as mature yet.
Most of the Small Cell activity is around 3G indoor (Enterprise) and LTE outdoor (Urban), with 3G still important indoors (for voice) and LTE HetNets seen as the longer term solution for capacity. At least four DAS vendors announced lower cost, simpler products intended to address larger buildings and stadia - highlighting the growing demand for in-building cellular solutions. Many new LTE Small Cell vendors are appearing on the scene. Residential femtocells still have a place in the market especially where integrated into a broadband modem or set-top box, driven by a different business case than before. There were some signs that the radical approach of Free France, who are shipping many 10Ks of femtocells a month, may be emulated by others.

What is WebRTC and where does it fit with LTE and IMS

This simple video from MWC should give an idea on what WebRTC is and can do:

So what exactly WebRTC is in technical terms. Here is a recent presentation from WebRTC Conference and Expo

And here is another presentation that explains where it fits in with the LTE Architecture.

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.

Interdigital's 'Fuzzy Cells' technology for cell edge performance improvement

Back in LTE World Summit 2010, I heard from Dr. Ariela Zeira, InterDigital's Vice-President of Advanced Air Interfaces about various things Interdigital have been working on.
One of the technologies that caught my attention was Fuzzy Cells technology to increase the cell edge rates. The following is from their press release for Mobile World Congress:
BARCELONA, Spain, Feb 15, 2010 (BUSINESS WIRE) -- InterDigital, Inc. today announced the demonstration of its "Fuzzy Cell" technology that improves cell-edge performance at the 2010 Mobile World Congress. The Fuzzy Cell technology is part of the company's comprehensive suite of "Next Generation Cellular" (NGC) innovations that combine advanced network topologies and spectrally-efficient air interface solutions for LTE-advanced and beyond.
"Many wireless operators and customers are experiencing a substantial degradation of service quality caused by the ever-growing demand for mobile data," said James J. Nolan, Executive Vice President, Research and Development, InterDigital. "We are at the forefront of developing solutions for more efficient wireless networks, a richer multimedia experience, and new mobile broadband capabilities that support operators to capture revenues from the boom in smartphones. The Fuzzy Cell fits nicely within our much broader efforts on spectrum optimization, cross-network connectivity and mobility, and intelligent data delivery techniques."
While cellular networks have become virtually ubiquitous, users continue to experience inconsistent and unpredictable performance when moving around. While this degradation is often the result of network congestion or an obstructed path of the radio waves, it is also inherent to traditional cellular deployments, whereby signals degrade towards the fringe of any given cell due to interference from neighboring cells. It is estimated that typical users experience this situation, known as being in the cell-edge, more than 50% of the time. Advancements in HSPA and LTE primarily increase peak data rates and only offer modest improvements in average performance throughout a cell.
Fuzzy Cells is a novel approach for leveraging existing resources to improve spectral efficiency and cell-edge performance. In a traditional deployment a device connects to one site at a time (even if multiple sub-bands are used at each site) and all sites use the same power levels and sector orientations for all sub-bands. In a Fuzzy Cell deployment, a device may connect to multiple sites at a time through the different sub-bands and continue to realize full system bandwidth. The power levels and sector orientations of the different sub-bands are optimized for best performance. In simpler terms, the device exploits the best combination of base station support regardless of its position, removing traditional limitations of cell or sector boundaries. Importantly, Fuzzy Cell technology can also allow gains indoors as it allows connection to more than one cell/sector at a time as available. The Fuzzy Cell technology provides additional improvement over Fractional Frequency Reuse (FFR) methods that are supported by current specifications.
The following shows the demonstration of Fuzzy cells:
I haven't heard any news recently on this technology but its an interesting concept, not sure if it would be adopted in the near term in the standards.

Practical innovation, Radical innovation and Incremental innovation at the Mobile World Congress

There has been a lot of coverage of mobile world congress. I have said before that the event was a success and also that we, as an industry are adding value when there is so much economic chaos around us. GSMA also validates this trend by their statistics and attendee numbers GSMA Releases Congress Visitor Stats

If there was an underlying theme for the event, then I think it was 'practical innovation' i.e. innovation designed to solve problems. This is a more interesting trend which I genuinely like. However, there is also space for radical innovation and also incremental innovation. Hence, I will discuss innovation in these themes below. By 'incremental innovation', I mean changes that take a few years to manifest but are significant. Most changes in the devices, networks and infrastructure will be in this space. The challenge for incremental innovation is: Customers may be overtaken by more nimble/sometimes imperfect. And then, there is radical innovation which may be a game changer

I will provide a series of links to announcements that caught my eye in the show (and afterwards). But first, a note of caution: Let's not forget what happened to Palm AFTER the MWC. Last year, Palm was an 'innovator' with much talk of its 'comeback'. Today, there is an overall doom and gloom around Palm. . Palm's products may be good .. But does it matter when the industry is moving so fast and customers have so much choice? Will developers continue to support a waning platform? Today, we see excellent new devices from Samsung, Microsoft, HTC and others which were not present a year ago. All this means that the rate of change has increased. This is a matter for optimism but also caution as the woes of Palm demonstrate.

Firstly, before we discuss further, some of the big announcements. Again, I provide links so that I don't duplicate much of what we have seen before.

BBC and Ubiquisys stream multiple videos over a femtocell at MWC 2010

Impressive. I suppose they are four simultaneous PS dedicated calls as all other approaches (Like Mobile TV Broadcast technology and MBMS) would not be applicable for Femtocells (atleast for now).

Femtocells for LTE

Picture Source: Continuous Computing

Going back to my old posts here and here, I mentioned that one of the ideas being floated is that to roll out LTE technology initially in Femtocells as that will give the device manufacturers and the operators an idea and a feel about the technology. All the gremlins can be ironed out before mass market take up.

As you may have heard (or know) that in UK, Vodafone rolled out Femtocells which have now been branded as 'Sure Signal' and the device now costs less than half the initial price. The falling prices is because of the fall in the Bill Of Materials (BOM) as well as operator getting more confidence and subsidising the femto's a bit more. Of course this fall in prices means increase in uptake and that is what is being expected by the industry.

At the same time, some small players are getting more interested in the small cells for LTE. The following is from an article in The Register:

Meanwhile, the femto players are looking ahead to LTE, where there are many indications from operators that tiny cells will play a big part in the strategy. The devices will be used from day one by some carriers - to offload data from the macrocell or to provide indoor coverage in high frequencies like 2.6GHz. They could also add capacity to deployments in low frequencies like 700MHz and even be used as a starting point for greenfield providers, which could then add macro networks later, explained Simon Saunders, chair of the Femto Forum.

Continuous Computing has been eyeing the femto market for several years from its heartlands in protocol stacks, core networking and traffic shaping. At MWC, it worked with picoChip and Cavium Networks to show the first complete LTE femtocell reference design. Available immediately, this includes the LTE modem, RF and packet processors, protocol software, intelligent router functionality and a complete Evolved Packet Core (EPC) simulator.

"The demand for LTE femtocells is unquestionable. We are already seeing operators asking for small cell access points to start testing in the second half of this year. Femtocells represent the key to avoiding the difficulties surrounding the first 3G deployments where roll-outs cost too much, took too long and did not meet user expectations," said Mike Dagenais, CEO of Continuous.

Ps: Also read the post on Metro Femtocells here.
