Looking to the horizon - 4G voice solutions
By Andrew Mitchell
Over 70 wireless operators from around the globe have now announced plans to and even begun to deploy 4G networks. For users the promises offered by 4G are most often viewed in the context of the mobile Internet - abundant and cost-effective bandwidth that enables compelling mobile applications and high quality multimedia experiences. Perhaps not always top of mind for users, the need for voice solutions has not diminished and meeting that need is something that a number of members of the 4G wireless ecosystem are aggressively pursuing.
4G Trends contacted Kevin Mitchell Director, Solutions Marketing - Mobile at Acme Packet to gain some insights and his opinions on this critical aspect of 4G wireless. Kevin obliged me with the following brief and informative interview.
Q: Data dongles and devices for LTE networks are with us today yet standards, let alone devices to deliver LTE voice have yet to emerge. What are the approaches currently being considered to deliver voice over an all-IP 4G network?
Until last year, the concern of how voice and messaging service parity would be achieved with LTE was overshadowed by a host of other issues in getting LTE to market. This is not a trivial topic as two-thirds to three-quarters of all mobile service revenue today comes from voice and messaging services. A standard is essential for LTE uptake, drawing from history where as a consistent approach to implementing voice services across service providers helped GSM take-off and become the most widely deployed mobile technology.
The good news is that a standard for voice does exist and it’s been around for a while: IP Multimedia Subsystem (IMS). Now on release 9, it’s a SIP-based next generation core service for not just voice, but multimedia communications as well. The GSM Association’s Voice over LTE (VoLTE) initiative is currently engaged in selecting a sub-set of the IMS standards to deliver end-to-end voice and SMS for LTE devices, including defining roaming and interconnect interfaces.
There are three other alternatives offered up by various industry players. Voice over LTE Generic Access (VoLGA) reuses legacy voice infrastructure and UMA/GAN technology. Today, T-Mobile remains the lone service provider supporter for VoLGA. Other service providers using UMA for FMC are noticeably absent. Circuit-switched fallback (CSFB), which uses some initial signaling over the LTE RAN and then actually “falls back” to the 2G/3G TDM RAN to establish calls, is another solution. The third option is a hybrid of SIP and legacy that leverages existing circuit MSCs, but uses SIP to deliver the voice to devices connected via LTE RANs or any fixed or mobile IP broadband access network.
But back to VoLTE, it’s not merely about service parity with legacy mobile telephony, but also about access convergence and multimedia communications that makes IMS compelling.
Also, a growing number of WiMAX operators offer residential or business voice today - it’s predominately a fixed offering, that is VoIP delivered over a broadband alternative to DSL, FTTx or cable.
Q: What about existing technology solutions such as Skype or Google Talk - are these viable alternatives?
Yes, sure they are alternatives, but with trade-offs, including best-effort “roll of the dice” service quality lacking emergency service support, lawful intercept and fully staffed customer support. Over-the-top communication providers are indeed a competitive threat and increasingly so with the bandwidth increases in 3G technologies and LTE. Today mobile service providers face a new challenge in avoiding becoming a dumb pipe to the richness of the Internet. This is the same challenge that fixed line operators have faced since the advent of broadband. However, I don’t think over-the-top is a mass market replacement for mobile service provider offered voice and messaging services.
As mobile service providers own access infrastructure and the EPC along with IMS/SIP-based services core, they can differentiate themselves from OTP ASPs with the likes of wideband voice codecs for HD voice, interactive video with QoS and Rich Communication Suite services such as integrated presence and diverse messaging.
There is room too for a federated model providing value and revenue all along the chain. The federation is between over-the-top providers and the mobile broadband providers where the strengths of each provider can be leveraged-innovation from the web and quality, security and billability from mobile service providers. There are tentative moves in this direction and peaks at this model with the likes of Verizon and Skype.
Q: With LTE networks already rolling out, what solutions can (or are) operators likely to employ until clear standards emerge?
As outlined earlier, there are 4 approaches available today or near future-VoLTE using IMS as defined by the GSMA IR.92 document is imminent. The limited geographic availability and form factor of LTE doesn’t demand voice at this moment (but soon). But LTE providers can offer voice softclients on laptops at the outset (and I think they should to minimize or prevent subscriber triple/quadruple play revenue loss from over-the-top). They can do this with MSC VoIP, VoLGA or VoLTE.
Q: What are the implications to 3G operators? Is there going to be a clear migration path to 4G voice and what would that look like?
Mobile service providers have not adopted much SIP or IMS today. However, nothing precludes them from doing so, and initiatives like Rich Communication Suite may incent adoption of SIP / IMS ahead prior to LTE deployment. The area with the largest SIP adoption is the core and IP interconnect borders, which does lay nice groundwork for migration to the 3G and 4G access networks. LTE is on the 5-year horizon for some 3G service providers, so they have time to roll-out IMS ahead of their 4G deployment.
VoLGA and VoLTE both offer migration, but only VoLTE offers services beyond voice and messaging of yesteryear. MSC VoIP is an interim step as well, where some investment is preserved for both voice-the MSCs at the outset-and the multimedia-SIP infrastructure for the years ahead.
Q: When can consumers expect to see the first 4G voice capable device?
For basic voice: today as a laptop with a LTE data card is a voice capable device. There will be LTE phones early 2011, but I suspect they will be dual-radio phones with voice from UMTS/CDMA and LTE being the primary data network (with 3G for non-LTE markets for data coverage). For a truly mobile LTE voice and multimedia communications device, I’d venture to say very likely in 2012. Although, once the LTE radio is available on a phone, anyone could make a call using over-the-top clients.
Tablets will come to Verizon LTE soon, and FiOS tablet could be ‘home-changer’
By Caroline Gabriel
While the iPad may be scoring consumer points by supporting almost every imaginable mobile behaviour, many other tablets will gain acceptance by enabling a specific function and delivering an optimized experience. Cisco has showed the way with its videoconferencing and home energy management tablets, and of course, Amazon with its Kindle e-reader. One of the most interesting examples of the trend emerged a couple of weeks ago when reports surfaced of a planned Motorola tablet, co-developed with Verizon to support its FiOS IPTV service, and more details have now come out.
A tablet for the TV could become something truly ‘home changing’. For Motorola the holy grail would have to be DLNA (Digital Living Network Alliance). This is a six-year old, highly labored industry grouping, begun by 18 of the largest constituents in the digital home and now swelled to 26 promoter members, from chipmakers to content producers to consumer electronics vendors to pay-TV operators.
This group has long established use cases for how content can move around a home. Those use cases are quite advanced and consumers are only now just beginning to see the fruits of fairly boring, but necessary, standards work and plugfests, which are the staple diet of this organization. In May, Nokia, Samsung, LG, Motorola and Sony Ericsson all obtained DLNA certification for some of their devices, though curiously this has hardly made it into the news pages at all - probably because those devices are mostly not launched.
Just last week the Alliance said that the number of DLNA certified Blu-ray players had nearly doubled to 105. And before phones, or tablets, can interact with TVs in the home, the core devices - Blu-ray players, TV sets and DVRs - have to make that leap themselves.
DLNA is all about accessing any content, mostly unprotected content, on any device in the home. We say mostly unprotected, because the DLNA has never really got to grips with DRM (digital rights management) and it has no strategy on interoperable DRM.
Until now it has been more interested in defining format types for, say, printers from mobile devices, or defining device classes, or adding support for H.264 video. But there are two ways it can deal with protected content. The first is if a content operator also offers a second device and supplies transparent DRM - this is something that Verizon could easily do, offering DRM keys to portable devices from FiOS, such as to this proposed Motorola tablet.
The other approach, and one we see very clearly on the roadmap of DLNA, is the idea of supporting streaming protocols such as RTP and offering link protection. That way streaming protection such as DCTP can prevent some level of piracy when the content is on the way to another device, and content can simply be streamed to a second device, with no copy being kept.
What DLNA makes possible is the ability to locate content anywhere in the DLNA universe in your home, so on a DVR, a camera, a PC, phone or home server, and shift it to be streamed on ANY of the other devices. This can also work with music and photos.
DLNA breaks all the devices into storage, controllers and rendering devices and makes them plug and play together. So you can watch a TV program on TV, decide to switch it to another portable device, and send the sound to the speakers on your laptop. What the DLNA had to deal with early on was the issue of control and giving control power to other devices. In this way your TV remote can increase the volume on the bedroom TV, where you just sent the rest of your TV program. Now it is embracing the streamed video world, not just one that relies on storing new copies of video files.
So what could a video tablet do? It could flip to the electronic programming guide of a pay-TV service, and then select a channel. It might send the program on that channel to a DVR or just pause it while you go upstairs to another room, and then let you trigger play. You might use the tablet to look up something on the internet, while watching another channel. It might deliver the sound to the channel you’re watching to your earbuds, or to your laptop, which has a better set of earbuds. It might let you control your Blu-ray player, and stream the video to your tablet, notebook or a TV.
All of that you get from DLNA certification. So that’s pretty much without reinventing anything, just putting tried and tested control features, and tried and tested stream and file types, on a new device. Every one of Nokia, Motorola, Samsung, LG and Sony Ericsson has already proved to the DLNA that they have code which can do all that, so it just needs porting to a new device, which will no doubt run Android, the same operating system that Motorola will have probably first delivered it on.
It’s the other features of the Motorola tablet device which are hardest to design. Well for sure it will play Android Market apps, so that’s games, streaming video services over Wi-Fi in your home and at work as well as some VoIP-style voice capabilities. Already this device is sounding cool to take out of the home, despite its core function being one that is attached to the pay-TV operator.
If you add a TV Everywhere service from FiOS, so that its pay-TV programming can be viewed anywhere over the internet for paying subscribers, including on this tablet, then it is a pretty neat device and probably capable of offering a better video serviced than Apple and iTunes. If that happens, Motorola will suddenly have improved leverage in the set-top world and also have a new product to ship to all of its existing IPTV operators. It might even be able to make it work with cable boxes too, though that comes with a different set of problems.
We have for some time talked about iTunes TV and Apple’s desire to offer TV channels on a monthly pay basis, to rival cable and other pay TV operations. Because it has not yet emerged, and potentially this is because Apple cannot get the kinds of content licenses that it needs, it may well put both Apple, as well as Google TV, at a huge disadvantage in home tablets. Tablets without content are just heavy Gameboys or MIDs.
But we know that Verizon FiOS has content galore if Motorola first targets the digital home at Verizon with tablet number one, and then frees up other tablets to work outside the home with cellular services, it could mount a viable challenge to the iPad outside of the AT&T cellular customer base - which is about two-thirds of the US. Of course people can buy an iPad without an AT&T data contract, either cellular or Wi-Fi, but the number that prefer to be sure that their data is paid for, before they start using a tablet is likely to be a lot higher than those who have their own Wi-Fi service.
The first Motorola tablet will be out during 2010, which is likely to make it one of the first that support Adobe Flash, and it will be thinner and lighter than the iPad, and offer two cameras, one to take pics and the other for video conferencing. All in all if Motorola has the same kind of success or better than it had with the Droid and Droid X, then it will seriously be in the tablet game through America’s second largest telco.
Whatever the future shape of the Motorola tablet, its reported plans highlight how important carrier support remains to the success of media devices - and also how intensely Verizon is relying on broadening its range of gadgets to boost its services and customer loyalty. This is true of FiOS, and also of its forthcoming LTE wireless data offerings. Much of the revenue growth on new networks will rely on non-traditional mobile devices, and the apps and content services for which they are optimized. So tablets, personal hotspots and media players could lure new users to 4G systems, rather than phones, a factor Clearwire has already embraced for its WiMAX offering. Now Verizon Wireless expects to launch tablets on its upcoming LTE network before it releases smartphones.
John Killian, CFO of co-parent Verizon Communications, said the cellco believes it will be able to charge a premium for the speed and quality of LTE services, especially when these are driving new applications or usage patterns. “Customers will pay for quality and premium service and premium speed,” he said. Verizon has previously hinted that it would use LTE as the trigger to introduce tiered data pricing, making it acceptable to consumers with improved quality of service and new content options.
He also said that Verizon would release tablets in the “not too distant future”, meaning early next year, while smartphones would arrive in mid-2011. The timeline, a reversal of the 3G pattern, will be partly down to the complexities of developing and testing phones, which will have to be multimode for CDMA roaming - not essential for data-only devices like tablets, dongles and hotspots, which will be usable just within areas of LTE coverage. It also demonstrates the importance of eye-catching gadgets supporting new services to encourage early 4G uptake.
On a webcast, Killian said Android would remain the centrepiece of its smartphone strategy, despite the rising expectation that Verizon will get its own iPhone. “I definitely think in terms of the Droid franchise we’re going to continue to be unique,” he said, adding, in response to a question about Apple: “All of our assumptions about our business is we’re going to have devices that act and perform just like the iPhone does. If the iPhone became available to us under the right terms, we would be interested in that.”
Russia shows how LTE build-out patterns will differ from those of 3G
By Caroline Gabriel
Over the past few years, the wireless vendors’ hopes have been firmly focused on the remaining major unbuilt 3G markets, notably China and India. But with Chinese roll-out slowing now, and India’s marred by delays, there is a new source of potential revenue in LTE. Thought this will be slow to gather steam, there are already signs that purchasing will follow a very different pattern to those of 3G.
One reason is that many governments and carriers will regard 4G as a fixed as well as mobile broadband platform. This means it will be deployed more quickly than 3G was, in many cases, in rural areas and emerging economies, because of the urgent need for high speed access. In this scenario, 4G - whether LTE or WiMAX - does not have to be a ‘network in search of an application’ as 3G often was.
The other reason is that some countries will aim to deploy 4G quickly in order to minimize investment in 3G, where this has been limited to date, and to kickstart mobile, broadband and web services expansion via the more cost efficient IP standards. In some countries, mainly in sub-Saharan Africa, 3G may be bypassed altogether, and in others, like Brazil, operators are discussing confining 3G to a few areas and using non-deployed spectrum elsewhere for 4G instead. This would be particularly practical where 3G investments have been fairly recent and used software upgradeable base stations, and where regulators are technology neutral.
One of the most interesting countries in terms of the 4G pattern will be Russia. In the top five growth markets for wireless, Russia’s 3G expansion has been slow and bureaucratic, but in 4G it is moving far more quickly as the momentum behind broadband and web services rises. It already has several WiMAX operators, one of which, Scartel/Yota, is also trialling LTE. The early WiMAX spectrum auction opened the door to some smaller players and now the three main cellcos - MTS, VimpelCom and Megafon - may face another wave of new competition as Russia gears up for its main tranche of 4G auctions.
Russia is facing a dilemma that has affected the spectrum policies of many economies - whether to let experienced operators expand wireless availability, or encourage new competition. The main cellcos are dismayed at president Dmitry Medvedev’s belief that new spectrum should be opened up to new entrants so that 4G services are spread more widely than 3G between different operators and business models. In particular, they are keeping a wary eye on the rising mobile ambitions of landline incumbent Rostelecom which gained licenses in the first tranche of 4G auctions. A second wave of auctions around 2.5GHz will be held later this year.
According to Russian business newspaper Vedomosti, Medvedev has told the minister of communications, Igor Shchegolev, to draw up plans to distribute ‘4G’ licenses on a broad basis. This could speed up development of new services in Russia, which is one of the world’s largest potential markets for wireless and broadband, but whose development has often been delayed by bureaucracy. In particular, localized carriers could be encouraged to bring access to rural areas, which are vast but sparsely populated in the highly urbanized country. Medvedev also hopes smaller players would introduce innovative web offerings and support government and industrial applications.
However, as the US and other countries have discovered in the past, new operators can be financially unstable and inexperienced, raising the risk that spectrum goes unused or new services fail.
Of course, Medvedev’s proposals are encountering fierce opposition from the big three. The newspaper reports that they have all written letters to Shchegolev and prime minister Vladimir Putin arguing that only they have the cash and expertise to handle the roll-out of LTE in Russia. This will not stop them lobbying for state support in the financing of LTE, though. Medvedev argues that national LTE will cost far more than 3G because he wants it deployed as much as 10 times faster than the sluggish pace of 3G, in order to support fixed as well as mobile broadband. This may require state financial support, which in turn will increase his negotiating power over the cellcos. Last week Vedomosti reported that Osnova Telekom, 25% owned by Russia’s Defense Ministry, is willing to help build the LTE system.
The Russian press says that potential new spectrum bidders are already making themselves known. They include Rusenergotelekom, a new firm formed last October and controlled by energy investor Grigory Berezkin, who also owns a blocking stake in national landline operator Rostelecom. This company is getting increasingly active in wireless services and has said it will increase its influence and revenue streams by supporting new mobile entrants in order to boost competition.
Rostelecom has also invested directly in spectrum. It was recently awarded 30MHz of spectrum in the 2.3GHz to 2.4GHz band, covering one-third of the country’s population, and plans to launch LTE test networks in Penza by the end of August. The carrier, an arm of state-owned conglomerate Svyazinvest, won licenses in 38 of the 40 Russian regions covered by the tender, while fellow Svyazinvest subsidiary Sibirtelecom got the license for the Tomsk area and local operator Vainakh Telecom won in Chechnya. The operators have 18 months to build and launch networks and must adopt Russian-made equipment. However, the largest cities, Moscow and St Petersburg, were excluded from the tender to give the big three cellcos - MTS, Vimpelcom and MegaFon - more time to get return on their recent investments in 3G.
Svyazinvest is currently undergoing a reorganization, combining Rostelecom with its local divisions nationwide to provide integrated fixed, broadband and mobile services, but the group has less power in the cellular than the fixed market. It has regional cellcos like Sibirtelecom, Uralsvyazinform and SkyLink, but has been rumored to be considering a bid for one of the big three, or even a start-up like Scartel/Yota, which has 2.3GHz spectrum in the main cities. Svyazinvest’s wins of new 4G spectrum make it the fourth largest cellco in terms of licensed area, overtaking Tele2. It plans an IPO in April 2011.
Another hallmark of Russian 4G is the way that its operators are using their subsidiaries in neighboring, former Soviet states to test LTE at a very early stage, with less cost and risk than building out in key Russian cities. So an unlikely nation, Uzbekistan in central Asia, has become the world’s first to gain LTE networks from two different operators - TeliaSonera’s UCell and Russian-based MTS. Both are primarily serving as testbeds for the cellcos’ larger owners, which can trial LTE in tough terrain but without the significant expense and risk of rolling out at such an early stage in their key territories. MTS recently switched on its LTE network in capital Tashkent and has plans for the main Russian cities once it validates the technology and acquires spectrum, probably later this year.
Meanwhile, UCell is a subsidiary of TeliaSonera, which was the world’s first operator to launch commercial LTE networks in Sweden and Norway, and is looking to expand the technology around its many bases in the Nordic, east European and central Asian regions. The two providers have a combined 78% market share in Uzbekistan.
UCell has turned to ZTE for its equipment, favouring the Chinese firm’s software defined base station architecture, while MTS is using kit from rival Huawei. ZTE now claims seven commercial or pre-commercial LTE networks and 50 trials while Huawei has been part of several high profile early awards, including Telia’s in Norway.
Uzbekistan may be a testing ground rather than a strategic market for its carriers, but it does illustrate a key trend - the squeezing of the upgrade cycle between 3G and 4G in emerging nations. In some areas, 3G may be largely bypassed altogether as operators chase the better economics and spectral efficiency of the new IP-based systems, and their superior ability to support fixed broadband and packet data services as well as mobile offerings.
My 51M Beats Your 100M
By Chris Nicoll
By Chris Nicoll, Distinguished Research Fellow, Yankee Group
We in the prognosticating industry (if there really is such a thing) like to forecast the beginning and end of things. And we are rarely correct. GSM didn’t commoditize mobile services to the point where there were not competing players offering differentiated services. Those of us in the North American market should probably have taken note. But we have several of our own examples to choose from too. The iPhone didn’t doom Verizon Wireless or Sprint or even T-Mobile into obscurity (nor did it kill off regional players like Metro PCS and Cellular South who are doing just fine, thank you) just as Verizon’s ability to offer a fixed/mobile bundle hasn’t doomed the other players. The question is not: Why didn’t it doom the other players; the question is: Why did we think it would?
So when the LTE networks show up later this year, is that the end of WiMAX in the US? I’m not a huge fan of how the Clearwire WiMAX network has been rolled out. I tend to think that when you are giving such a long runway to gain market advantage, you should probably sew up the major markets before competitors come to play. I don’t think there is much advantage to playing in the smaller markets but not in the major ones. Maybe I’m wrong. But I don’t think so.
But despite the Clear/Sprint 4G network currently covering only approximately 51M of the US population, when Verizon is expecting to cover over 100M by the end of this year, I don’t think we can sound the death knell for Clear either. Yes, I know, there are rumblings about Clear moving to LTE, but ahead of the Harbinger network Clear is starting to offer wholesale services (can you say Best Buy?) showing a bit of strategy flexibility. Good move. And I think the facts will show that in two or three year’s time, there are folks who just like the Clear service, brand and are loyal customers. Seriously, we can’t really take that for granted. Toyota knows this all too well. It took its lumps, but has bounced back handsomely. Clear may end up shifting technologies to LTE, but will there be a Clear in two or three years? Yeah I think so.
What is clear (no pun intended) is that there is not ONE market all of these operators are dipping into. There are MANY (and I’m not even going to try and spell them out right now) markets, with differing price points, service needs and even device requirements. Think not? I point again at the Sprint Pre-Paid services and those are masterfully aligned with different market requirements: Virgin Mobile for data heavy users, Boost for voice users, Assurance for low-income families and is supported by state programs, and Common Cents Mobile for the budget conscious. Not to mention Sprint’s Post-Paid users.
Just as there is no one killer app, there is not a golden technology bullet solving all problems and no one device to fit all users. There is also not one best network or one user to fit all markets. We should all stop talking like there is one.
The US race to 4G accelerates as Verizon launch looms
By Caroline Gabriel
The US mobile broadband market is becoming an Olympic-class race, in words as well as actions. Clearwire continues to expand its network and has an important new deal with Best Buy, but has to fight hard to maintain its headstart over Verizon’s LTE roll-out, as the cellco reportedly ups the ante itself. Meanwhile, Clearwire’s wholesale model will get a new competitor with the LightSquared LTE venture, assuming that delivers real results in its mobile satellite spectrum.
According to the IntoMobile blog, Verizon plans to cover more POPs with its LTE network this year than previously thought. Citing unnamed sources, the researchers said the carrier has been cautious about its public roll-out targets and actually aims to cover 115m to 120m POPs, rather than 100m, by year end, with commercial services planned around Atlanta and Dallas/Fort Worth as well as eastern Massachusetts, in addition to the announced launch bases of Seattle and Boston. Verizon did not comment, but has previously said it would cover 50-60 markets by early 2012 and fill out its 3G footprint by the end of 2013.
Meanwhile, Clearwire can be judged by real results rather than promises, and this month it announced the availability of its WiMAX services in five new cities, raising its coverage to 49 markets and 56m POPs. The new markets are mainly midrange ones already covered by Clearwire’s legacy broadband service - Jacksonville, Florida; Wilmington, Delaware; Stockton and Modesto, California; and Grand Rapids, Michigan. But 56m is less than half of the target of 120m by year end - a target that Verizon Wireless is chasing.
The real impact will depend on where those POPs are and how receptive they are to the new services. One analyst firm, TownHall Research, believes Clearwire has fallen behind in coverage terms but is getting higher than expected penetration and uptake in the markets where it does go live. Also, Clearwire may well light up some major metros in the last quarter of the year, adding significantly to its POPs total.
With mounting bills, Clearwire reported a widening second quarter loss. Uptake of its services is better than most predicted, but at this early stage, investment in network expansion is bound to outrun revenue growth. The loss was $126m or 61 cents per share, compared to last year’s $73m. The results included a loss of nine cents per share for inventory adjustments. Excluding that item, the loss would have been 52 cents per share, in line with analyst expectations. Revenue rose 93% to $122.5m, behind forecasts of $132m.
Clearwire added a net 722,000 subscribers in the quarter, to end at 1.7m. Its base received a significant boost from the launch of the HTC EVO, the US’ first WiMAX capable smartphone, by Sprint, which runs its ‘Sprint 4G’ WiMAX/CDMA service on Clearwire’s network (and holds the largest stake in the start-up). The success of the EVO is good for Sprint but has a more limited effect on Clearwire’s own financials because many subscribers have taken the HTC superphone even in areas with no WiMAX coverage. The company receives only a “nominal” fee for them, it said.
The WiMAX carrier also followed through on pledges to keep its technology options open, and is to start testing LTE, which it could potentially use in future for new markets, or alongside WiMAX. Any switch would be unlikely to happen until 2012 or later, once the TDD version of LTE has commercial equipment and an ecosystem. Clearwire has only TDD spectrum, although it said it would test an FDD implementation with paired 20MHz channels since it has so much spectrum capacity that it could deploy 40MHz per carrier in many markets.
Clearwire said it would test LTE in its 2.5GHz spectrum using Huawei and Samsung gear. CEO Bill Morrow said the firm was “by no means committing” to deploy commercial LTE in future but it aims to demonstrate to backers that it has flexibility. In particular, it wants to prove that the two technologies can coexist, so that an LTE strategy would not entail a full rip-out of current networks.
“As we have consistently stated we remain technology agnostic,” Morrow said on the Q2 earnings call. “If we elect to add LTE to our network at some point we could do so using existing core infrastructure and backhaul.”
LightSquared has an even tougher hill to climb to hit the targets for its LTE network in satellite bands. Philip Falcone, the billionaire head of LightSquared’s backer Harbinger Capital, is said to be in advanced talks to lease this spectrum to third parties, which would sweeten the business case (and an approach Clearwire may also adopt) and CEO Sanjiv Ahuja says it has already reached agreements with device makers.
“We are talking to most of the wireless players,” Ahuja said in an interview last week (though AT&T and Verizon are barred from using the new network by the FCC). “We want to serve every player in this industry, from the largest to the smallest.” Like Clearwire, the wholesale model will target wireless, wireline and cable providers, as well as device makers and game manufacturers. Leasing capacity to them before the network is built out would add a nearer term revenue stream, but many analysts expect LightSquared to sell out to a major carrier, or at least lure one into a joint venture like Sprint’s with Clearwire. RBC Capital Markets’ Jonathan Atkin commented to Bloomberg: “To start out from scratch and build out a network from the ground up is highly speculative. An established company has the resources and manpower to really make this work on a national scale.”
Initial trials of the actual wholesale network will take place in early 2011 in Baltimore, Phoenix, Las Vegas and Denver, Ahuja said. And LightSquared has signed its first public partner, though not a major operator, but a vendor focused on the burgeoning market for the smart grid.
Airspan Networks, which made its name in broadband wireless access and WiMAX infrastructure, has signed an exclusive deal to market spectrum to utilities on behalf of LightSquared. Airspan will market the 1.4GHz wireless backhaul solution, including spectrum, equipment and services for smart grid applications in the electric, gas and water utility sectors in the US. It will manage the frequencies and potentially the networks, and will help utilities to build optimized proprietary grid management networks.

Reliance Infotel to choose WiMAX in India after all
By Caroline Gabriel
When the Indian BWA spectrum auctions concluded earlier this year, it seemed that the 2.3 GHz TDD band - once considered a clear run for WiMAX - would actually be split between that technology and TD-LTE. While state-owned telcos BSNL and MTNL are already deploying WiMAX in their 2.3 GHz spectrum, the privately held winners were more divided. The only one of these players to get licenses nationwide was Infotel, which was quickly snapped up by Indian conglomerate Reliance Industries (RIL). The firm implied that it would choose LTE for its new frequencies, even though Infotel had previously been committed to WiMAX, but now the firm appears to have opted for the more readily available technology after all, in the interests of early market impact
The other BWA victors only gained licenses in selected circles or operating regions. Qualcomm won in four circles and will recruit local partners to create a foothold for its favoured platform, TD-LTE. However, equipment will not be commercially available at prices to suit the Indian market for at least a year so these licenses look set to stay dormant for the time being. Other winners were Aircel, in eight circles, Bharti Airtel in four, Tikona in five and Augere in one. Tikona and Augere are committed to WiMAX while the two cellcos are undecided as yet.
Like RIL, they will face the choice of a technology that is available now, with a growing ecosystem driving down prices; and one that involves a hiatus period but is more closely integrated into the broader LTE market, promising possible economies and synergies in future when operators have deployed LTE widely in FDD spectrum. This dilemma explains the growing interest in software defined base stations that make it simpler for carriers to support both technologies, coexisting in different markets and business models, or with the flexibility to migrate from one to the other if conditions demand.
This is likely to have been one factor influencing RIL, which knows it needs to deploy quickly to meet India’s desperate shortage of broadband and wireless capacity and to steal a march on rivals. When it acquired Infotel, it referred specifically to LTE, even though its new ISP arm had been trialling WiMAX and planning to use it if it won licenses. But now it is taking the more pragmatic route and has begun its own WiMAX trials this month, according to company sources, which say the firm has installed five WiMAX base stations, testing kit from Alvarion and Samsung and working on interoperability.
RIL’s decision may be the first crack in the armor of TD-LTE, showing that the technology is not as close to market readiness as its supporters suggest. The operator gets a headstart in 4G and an improved bargaining position - buying affordable WiMAX equipment now and setting the benchmark for LTE equipment prices. Even if it introduces FD-LTE or even TD-LTE in future, there will be coexistence for at least 4-5 years and possibly permanently.
Having re-entered the telecoms space for the first time since it divested its mobile arm, now Reliance Communications, RIL is expected to form closer ties with that company. RCom also has significant WiMAX activities, which fit into a growing pattern for operators to harness the IP technology, and the TDD spectrum it targets, to build international power bases at relatively low cost. This spectrum is often cheaper than cellular focused FDD bands, and provides a lower cost, lower profile route into new markets than big ticket expansion programs like France Telecom’s in Africa. Even this roadmap, which relies heavily on acquiring mobile operators or licenses, is also supplemented heavily by investment in WiMAX players and spectrum. Others, like RCom, Orange spin-out Augere, ChinaTel and even Clearwire are focusing entirely on Clearwire and on the TDD bands, banking on an explosion of usage and value in unpaired TDD because of its suitability for IP-based data applications.
Augere has funding from Orange and has launched networks in Pakistan, Bangladesh, Rwanda and Uganda, and has an Indian license in some circles. It is likely to form part of its investor’s broader program to establish its presence throughout Africa and south Asia.
Clearwire is cultivating partnerships in India, China and other parts of Asia and Latin America, and has spectrum in several European markets, and networks in parts of Spain and Denmark. This week, it announced that it had acquired a 7% stake in another WiMAX operator, Ireland’s Imagine Communications, for €5m. The US firm will transfer its own Irish network and customer base, and 400 cells sites, mainly around capital Dublin, to Imagine. Clearwire launched wireless broadband services in Ireland in 2005 and the Irish unit generated a pre-tax loss of €13.4m on sales of €8.3m in 2008. Imagine has launched its service in 15 towns around Ireland.
Meanwhile, US-based Chinatel Group, in partnership with CECT-Chinacomm Communications, owns exclusive rights to roll out WiMAX to the 29 largest cities in China - despite that country’s general preference for TD-LTE. It is mandated to cover the first 12 cities by June 2011 and has completed partial deployments in Beijing, Shanghai and Shenzhen. It has about $640m in funding and is also active in Peru.
As for RCom, the firm created a separate business unit, Reliance Globalcom, in 2008 to push into 50 markets by 2012, largely on the back of WiMAX and fiber investments. It aims to become a multinational operator in fixed and mobile services, taking its place among the new breed of global providers emerging from outside the traditional mobile economies, many of them looking to use WiMAX to support 4G-style and fixed broadband offerings.
NSN snaps up most of Motorola’s wireless networks unit
By Caroline Gabriel
Motorola is not waiting until its planned break-up to offload its wireless networking business, and as expected, Nokia Siemens is to acquire the bulk of those activities. NSN will pay $1.2bn for most of the operations apart from the iDEN system used by Sprint’s Nextel arm.
The main attractions for NSN seem to be a strengthening of its US base and the addition of CDMA to its portfolio. These were the same factors that led it to bid for Nortel’s CDMA and LTE unit, where it was gazumped by Ericsson.
CDMA itself may be a declining platform, but carriers using the technology are in the forefront of the migration to LTE - while W-CDMA operators are, in many cases, relying on the extended HSPA+ roadmap to expand their networks before leaping to 4G, their CDMA counterparts have a nearer term need to implement next generation standards. Without an established presence among these CDMA majors, NSN has been at a disadvantage in bidding for LTE contracts. Although it gained some IMS business at Verizon Wireless, for instance, it lost out in the main RAN and core deals. It has said that it hopes to muscle into that deal in a future round of tenders, and a greater knowledge of CDMA will help.
It will be cheered by Verizon’s official reaction to the deal. “Verizon views today’s announcement as good news for the global wireless industry,” said CTO Dick Lynch in a statement. “This deal brings together two important Verizon suppliers; we look forward to our continuing work with Nokia Siemens Networks.”
Of course, Motorola’s CDMA installed base is significantly smaller than that of Nortel (now Ericsson) or market leader Alcatel-Lucent. But NSN will gain useful footholds around the world, most notably Sprint in the US and KDDI in Japan (which is already trialling Motorola LTE kit). The firm expects that the addition of Motorola will make it the number three wireless infrastructure vendor in the US, number one foreign wireless vendor in Japan, and “strengthen its current number two position in the global infrastructure segment”. This will, at least for now, put it ahead of the encroaching Huawei.
As well as its CDMA base, Motorola also has particularly strong expertise in the TDD flavor of LTE, thanks to its heavy investment in another TDD technology, WiMAX, and created China Mobile’s TD-LTE network in Shanghai along with Alcatel-Lucent.
It is not clear what NSN might do with the WiMAX business. Having virtually exited W-CDMA, Motorola focused all its efforts outside the 2G and CDMA worlds on WiMAX, and more recently LTE. It has a top three position in WiMAX, including deals with Sprint’s Clearwire joint venture, and has created a common platform that can run WiMAX and LTE. However, NSN quit WiMAX at an early stage, despite initially winning part of the Sprint deal itself, and has focused entirely on LTE.
Its options are to sell on the WiMAX activities, perhaps to a more committed WiMAX player like Huawei, Alvarion or Samsung; defocus on them and try to convert the higher profile customers to TD-LTE; or re-enter the WiMAX market, an option that could become attractive if Reliance Industries does decide, as seems likely now, to adopt the technology in India.
As for the legacy CDMA business, NSN has a clear interest in that installed base in the developed economies, especially north America, but may be less enthusiastic about supporting and evolving CDMA systems for emerging economies where LTE is a distant prospect. ZTE, in particular, is becoming dominant in low cost CDMA.
The deal is the latest step in a consolidation process that has been reshaping the wireless infrastructure business as its products become commoditized, driving players to seek greater scale and put more emphasis on higher margin activities like services. Nokia Siemens was itself created from this process, while Alcatel and Lucent also merged, and Ericsson acquired first Marconi Networks and then many units of Nortel.
Huawei was reported to be interested in Motorola Networks and even to be in talks with the US government to help pave the way for a Chinese bid, but has been pipped to the post again by a rival. In its statement, NSN said the acquisition would “significantly strengthen Nokia Siemens Networks’ presence globally, particularly in the United States and Japan” and that it would “gain incumbent relationships with more than 50 operators and strengthen relationships with others ….. it will give the company a large global footprint in CDMA.”
As for Motorola, it divests a business in which it no longer has the scale to compete effectively, despite its 4G breakthroughs. And it retails “substantially all the patents related to its wireless network infrastructure business”. This shows how important LTE IPR is, even to companies that have limited prospects in the equipment game. The rump of the bankrupt Nortel also retains significant LTE patents, and could sell these on - for a higher value than they would have attracted if bundled into the Ericsson deal - or even set up a standalone licensing company. The same options will now face Motorola.
The companies expect to complete closing activities by the end of 2010. Many questions are still to be answered, such as the fate of the government, enterprise and public safety businesses, which were to have been included in the newly named ‘Motorola Solutions’ along with wireless infrastructure. This company was to have been one of two created next year when the company plans to split in half - the other will be the handset and set-top box units, renamed Motorola Mobility. Motorola retains these other elements, but may be seeking buyers. Indeed, it seems likely NSN will add the public safety unit to its purchase, at least as a joint venture with Motorola. The companies’ joint statement said they were “exploring a global relationship in the public safety arena. This relationship would combine Motorola’s leadership in providing solutions to public safety organizations with Nokia Siemens Networks’ commercial LTE solutions.”
Commenting on the deal, NSN CEO Rajeev Suri said: “This is an exciting acquisition that I believe has significant benefits for customers, employees and our shareholders. Motorola’s current customers will continue to get world class support for their installed base and a clear path for transitioning to next generation technologies while employees will join an industry leader with global scale and reach. Nokia Siemens Networks will see the benefits of a deal that is expected to enhance profitability and cashflow and to have significant upside potential.”
Greg Brown, co-CEO of Motorola, said in his statement: “This is great news for our customers, our investors and our people and will allow us to sharpen our strategic focus on providing mission and business critical solutions for our government, public safety and enterprise customers.”
Motorola claims to be the market leader in WiMAX, with 41 contracts in 21 countries; and to have 30 active CDMA networks in 22 countries; plus more than 80 active GSM networks in 66 countries.
“As customers look to transition from CDMA networks to next generation technologies, the addition of the Motorola wireless network infrastructure business is targeted to ensure that we are well placed to meet those needs,” said Bosco Novak, head of customer operations at NSN.
About 7,500 employees are expected to transfer to NSN when the transaction closes, including large R&D sites in the US, China and India.

Signalling storm tackled from both ends of the RAN
By Caroline Gabriel
Femtocells are starting to gain real operator momentum - just this month, AT&T has extended availability round the US, and Vodafone has gone live in Spain, adding to its UK and French roll-outs. Most of these deployments still focus mainly on improved in-home coverage, but carriers are looking for a wider range of functionality and applications in future, and the femtocell platform is expanding rapidly. The latest evidence - enhancements from the main femto silicon provider, picoChip, that support up to 400 smartphones at once in always-on mode, and address the problem of smartphone ‘chattiness’.
This issue has been heavily highlighted lately, but mainly by vendors basing their solutions on traditional macro RAN and core technology. In particular, Nokia Siemens has sought competitive advantage by talking about signalling storms, and it has a high profile commercial client under its belt, having been enlisted by O2 UK to help its network withstand the onslaught of iPhone data. NSN set up its Smart Labs earlier this year, enabling it to examine all aspects of the handset, including operating systems, applications and infrastructure.
O2 installed NSN’s High-Performance Site Solution, which doubles the number of sectors per base station to six from three to boost capacity, plus software upgrades to effect a threefold reduction in the signalling load, to ease congestion.”You could solve this problem by just throwing more hardware out there but that is a very expensive way and there is no business case,” NSN told TotalTelecom.
But as with all aspects of network design, the incorporation of the femtocell into the heart of the access network could offer different approaches, as picoChip’s innovation demonstrates. Its latest enhancements, which implement features included as picoChip standards but rarely implemented until now, use the UK firm’s ’smartSignalling’ technology, now included in the picoXcell system-on-chip platform for femtos or available as a firmware upgrade. This “employs a collection of techniques to increase the effective signaling capacity within a cell and reduce the signaling required by each handset”, according to the vendor.
The UK-based firm says its PC3×3 series of chips, which underpin picoXcell, can already support 64 users, taking the architecture beyond the home device and into the realms of enterprise of even outdoor metro access points. As VP of marketing Rupert Baines puts it: “That is a pretty big femto - intended for metrozone or a bigger enterprise. It is past pico and creeping up on micro.”
The latest additions, though, make that scale usable in the real world, by dealing with the particular issues of smartphone behavior, particularly the constant signalling and ‘checking in’ that always-on handsets do when using applications like social networking or push email. This is an issue that has been highlighted in recent months by many companies, perhaps most vocally by Nokia Siemens, which points out that a ’signalling storm’ can have as destructive an effect on a network as high volumes of data traffic. picoChip agrees, and claims to have addressed the issue, in so doing increasing network efficiency and extending handset battery life.
The updated picoChip architecture enables a femtocell that can support 64 users in active conversation or web browsing, and 400 phones engaged in general network signalling or ‘chatter’. The chip designer hopes this will enhance the operator business case by proving femtos are usable for large scale deployments, including outdoor metrozones. This could significantly expand the clear but somewhat limited business case that exists when the femto is confined to the living room, and address some hot cellco issues such as offload from the macro network, and building efficient ‘hotzones’ for urban areas of heavy and unpredictable usage.
The main tactics used by smartSignalling are to support special handset ’sleep’ modes, such as Cell_PCH, which require fewer signaling messages to ‘wake up’; additional specialized channels for signaling information via Common E-DCH and Enhanced Cell_FACH functionality, which allows many devices to share a base station efficiently.
ABI Research analyst Aditya Kaul wrote in a blog post: “Compared to Wi-Fi offload this gives femtocells an edge for sure, as Wi-Fi is primarily meant to offload capacity and not signaling traffic. With collapsed RNCs, femtos are able to take most of the signaling traffic off the operator core network.”
Also, in the run-up to the Femtocell World Summit in London next week, picoChip added a further $20m to its warchest, bringing its venture capital funding to date to $110m. The financing came from existing investors - Atlas Venture, Highland Capital Partners, Intel Capital, Pond Ventures, Rothschild, Samsung and Scottish Equity Partners - and was announced to coincide with the sale of the firm’s one millionth chip.
The start-up has enjoyed a firm grip on the merchant market for femto silicon during the warm-up phase of the market, and is seeking to capitalize on that headstart and gain scale, in order to fend off the larger competitors, notably Qualcomm, that plan to enter the game over the coming year. “As we execute against our plan we have raised additional equity funding that will set the company on an even steeper growth curve,” said CEO Nigel Toon in his statement. Other priorities for the new money will be accelerated development of new LTE and HSPA+ products and self-organizing technology.
Currently, picoChip says it is on track for more than 50% quarter-on-quarter revenue growth in calendar Q210, driven mainly by the picoXcell femto range. The company now claims 25 femtocell customers supporting HSPA(+), LTE and China’s TD-SCDMA.
A dozen operators now have live femtocell deployments, with Vodafone Spain the most recently announced, while a further 45 or so are engaged in trials. ABI Research believes femto shipments will exceed 40m units in 2014.
Toon added: “Technology advances like ‘flat architecture’ and ’small cell’ will mean a radical shake-up in the established landscape.”
