iBurst may give WiMAX run for money

One of the themes that emerged from the LTE World Summit was that no one was looking at WiMAX as a competitor for LTE. LTE is being thought as 'Mobile Broadband' whereas WiMAX is being thought more of as 'Low-mobility/Fixed Broadband'. They would serve different needs and their market will hardly overlap. I have blogged about iBurst in the past and I think it may give some competition to WiMAX.

David Brunnen from Personal Broadband UK (cant find their website) gave an interesting perspective on iBurst and even though many people have not heard of it, it can still compete in the market. They have a big presence in Australia and last year won the spectrum for the whole of Ireland + Northern Ireland between 1785 - 1805MHz. Even though they have won the 20MHz band, they think that they can do with 5MHz or maximum of 10 MHz. They have also partnered with iBand and would probably allow roaming between them.

The main thing about iBurst is that it has very good spectral effeciency and an average throughput of around 600kbps. Data Rate of 1.061Mbps downlink/ 346Kbps uplink with System capacity 24.4Mbps downlink/ 7.9 Mbps uplink is supported. At the same time it offers high mobility with handovers at speed of over 100kmph. The cell radius is 1.5-3km in urban and 5-7km in rural area. Because of adaptive antennas, the same frequency can be reused and the interference can be reduced thereby increasing the cell capacity.

The biggest problem with iBurst is that there are very few players. Kyocera is the only base station supplier. On the devices side, Kyocera is the lead player but there are other new players like Dovado which has won some big contract with first US iBurst operator and Moovera (bought by Icomera) which also has some similar devices.

Last year Kyocera announed that iBurst has more than 140,000 subscribers. This year iBurst South Africa has been shortlisted for an award of "Best Operator in Developing Country". In last 6 months they have increased the subscriber numbers by 30%.

With the big players heavily invested in HSPA+/LTE and many others having a foot in WiMAX, it would be interesting to see how a possible iBurst success might be viewed. I would like to hear from people who have experienced this technology on what their feeling is about iBurst.

For more information on the iBurst technology, see Kyocera's iBurst Technology homepage.

Latest news on iBurst available from website.

LTE Roll out updates from the 4th LTE World Summit in London

As I mentioned in an earlier post, I got the opportunity to attend and meet with the industry experts in the 4th LTE world summit. There were some very interesting discussions and debates and some announcements about the rollout of LTE. Here is a quick summary of the announcements and news. I am sure to have missed some and will expand on some of the topics in later posts.

Karri Mikkonen, Director, Corporate Strategy, TeliaSonera in his presentation said that TeliaSonera to be an early LTE adopter with rollout planned Mid 2010. They have already bought licenses in Sweden, Norway, Finland, Denmark, Baltics. According to them LTE enables very convenient mobile data usage scenarios, and is one tool to win battle in mobile data, among others.

Bill Huang, General Manager, China Mobile Research Institute gave a very interesting perspective on mobiles in China which I will expand in a later post. According to his presentation, China Mobile will be deploying TDD based LTE (TD-LTE) option probably around 400Mhz spectrum. Trails will start by Mid 2009 and pre-commercial launch will happen around end of 2009. By Q2, 2010 there will be large scale commercial trials involving around 15,000 base stations.

Remi Thomas, Director of NGMN project and head of Network Strategy, France Telecom, France said FT plans to introduce HSPA+ and opt for 'wait and see' approach for LTE. The earliest they want to even think about LTE is after 2010 and if practical the rollout may occur in 2012. Even with HSPA+ they will opt for all the software changes only and not go for any hardware changes. So we wont see MIMO anytime soon with HSPA+ according to them. They also have plans to rollout LTE Femtocells when available to check the technology and iron out the problems with LTE technology.

Erik Ekudden, Vice President, Group Function Technology, Ericsson, Sweden in his presentation said that E\\\ will be commercially releasing equipment in 2009. Terminal HW including support FDD and TDD modeof LTE. For FDD, initial support will be for IMT core band of 2.1GHz and also IMT extension band of 2.6GHz and US 700MHz spectrum. For TDD the initial support will be for IMT extension center gap in 2.6GHz spectrum and 2.3 TDD band in 2.3GHz band.

In a question answer session, Dr Howard Benn, Director of Cellular Standards, Motorola Mobile Devices mentioned that Motorola already has a working LTE UE but not in Form factor (probably development board). He did not expand on the details.

Nick (Norikazu) Yamasaki, Manager Standards Strategy section, Emerging Technologies and Spectrum Division, KDDI Corp. in his presentation said that KDDI is a CDMA2000 operator but since with UMB nearly dead (my words) they have decided to eveolve to LTE. LTE deployment willbe started around 2012 but will co-exist with the CDMA 2000 network which they will support for another 10 years. Right now they have EV-DO Rev.A but they may also opt for Rev.B

One of the big problems that was discussed many times in the conference was that Release 8 LTE standards have no solution for the normal CS voice call. There are some hacks around it but voice part will only be solved in time for Release 9. This could delay decisions by some operators to roll out LTE networks untill after Release 9. I will write a post on this later.

Mobile advertising will grow

As the technology has evolved over the last decade so does various mobile applications and services related to it. In today’s competitive and saturated market operators and vendors are spending significant amount of time in drafting new strategies which will result in new revenue generation.

It is all about making the consumer interested and getting into the feeling of the general public in terms of what they would like and what would interest them. Mobile advertising is one such step in that area.

In the last year alone mobile advertising had emerged and there is a buzz out there related to it. I have noticed that people including myself take more notice of a mobile ad than advertising on TV or on a PC screen. And with a billion new phones being bought every year, the potential market is huge. Does this really mean that people out there really believe that it's going to be worth billions in just another two to three years?

There is no denying from the fact that mobile phones offer advertisers many different ways to reach an audience. With more and more people accessing internet from their mobile there is a potential area for growth. Placing ads at the start of a video or adding them to the results of a mobile search are less intrusive forms of promotion. I think we'll see people responding well to this kind of ad.For one thing the credit crunch will force advertisers to reduce traditional outlets like print and TV, and push them to explore cheaper and more targeted avenues, such as mobile devices.
So eventually, revenue from mobile advertising might rival that on other channels. But until then the industry will have to knock a few zeros off its forecasts.
You mist have noticed receiving various SMS from your operator sending you a message related to some product or event. SMS advertising for consumer goods, such as food and fashion is rising significantly specially in Europe.

Recent study by comScore suggested that more customers were getting ads for consumer goods such as food, fashion, restaurants, travel and financial services. In the three months ended August 2008, the number of offers received for non-mobile consumer goods rose 15 percent, compared to last year.

Food is the fastest-growing category of SMS advertising since August 2007, at a rate of 53 percent, followed by clothing-fashion at 38 percent and restaurants at 37 percent.
Mobile advertising is relatively new in the market and just like any other new thing it will take some time to settle down. However there are some articles floating around which suggest that mobile advertising is overhyped. Although these suggestions are based on some fact and data collected by the reputed analysts, I still do believe that mobile advertising will pick up especially after the latest credit crunch. In my view every time we see a launch of a new product or new technologies there is an excitement around it and in this process sometimes it gets overhyped. Same might be true with mobile advertising as well.

But like the Internet revolution before it, mobile needs to emerge from the technology foothills and develop media experiences and advertising solutions that delight and satisfy real consumers' needs and wants.

Mobile TV getting attention again

Nokia N96 with Mobile TV capability (DVB-H) has recently been launched in UK but there is no one broadcasting any Mobile TV. Maybe the operators are hoping that once there are enough handsets with this capability, Mobile TV can be launched and hopefully people will view it.

Last month, Juniper Research released a report likely to strike fear in the hearts of operators betting on consumers' willingness to pay for mobile TV content. In "Opportunities for Streamed & Broadcast Services, 2008-2013," Juniper projects that by 2013 some 330 million people worldwide will have handsets that can receive analog and digital broadcast TV signals — but less than 14 percent of them will sign up for pay mobile TV services.

"The development of terrestrial TV-capable receivers with comparatively low power consumption, and the availability of these receivers in mass market handsets, throws into question the business case for the deployment of a dedicated network in many markets," said report author Dr. Windsor Holden.

In Germany, Mobile 3.0's DVB-H trial flopped when operators started promoting their own TV-capable phones designed to receive DVB-T signals for free — undermining Mobile 3.0’s pay TV business model.

Last July, Toshiba shut down its Japanese satellite mobile TV subsidiary, Mobile Broadcasting, because the subscriber base wasn't big enough to support the business. But it wasn't because the Japanese aren't watching mobile TV. In fact, shipments of handsets able to receive Japan's free 1-seg mobile TV service continue to soar according to the Japan Electronics Information Technology Association — 10 million in the first half of 2008, bringing the total of 1-seg units shipped to 30 million.

Of course, the situation is markedly different in the United States where carriers have a lock on the handsets available to subscribers. And so far, that has effectively stifled competition from devices that can receive free-to-air TV. But with more free-to-air devices hitting the market, it's reasonable to question whether that trend will continue indefinitely.

In another announcement last month, IHT reported that France presented plans to set aside about a fifth of the country's prime television broadcasting spectrum for mobile Internet and television services by the end of 2009, in what supporters described as a major step toward creating a harmonized mobile broadband network in Europe.

France is the first major European country to reserve part of its most valuable broadcasting spectrum, the so-called UHF band, for mobile broadband and video services. Finland and Sweden have also said they plan to reserve the band for mobile services.

If a Europewide broadband network were to come to fruition, its greater scale would probably push down the cost of Internet services to consumers, especially in rural areas not reached by fast, fixed-line networks. It could also enable large mobile operators to sell services, like mobile TV or mobile broadband, across national borders, further increasing competition and lowering consumer prices.

The move was hailed by mobile operators and by the European Union's telecommunications commissioner, Viviane Reding, who is proposing that her office be given a greater role in influencing how EU countries redistribute the frequency.

The French plan, disclosed by Eric Besson, a French state secretary responsible for evaluation of public policies, commits France to reserving 72 megahertz of prime spectrum that is currently being used exclusively by television broadcasters - the 790 MHz to 862 MHz band - for mobile broadband services by the end of next year.

Besson said the country's broadcasters would be able to use the remaining portion of the UHF spectrum - 470 MHz to 790 MHz. He said that would still be enough to support 11 terrestrial broadcasters plus two new mobile TV broadcasters, owned either by mobile operators or TV broadcasters.

Sami said the French plan would most likely influence other European nations to make a similar redistribution. Britain, he said, is also leaning toward devoting a portion of that spectrum, from 806 MHz to 862 MHz, for mobile services.

In Germany, DVB-H licensee Mobile 3.0 handed back its licence to local regulators. The return of the licence was ordered by the authority for private broadcasters - Zulassungs- und Aufsichtskommission für den privaten Rundfunk (ZAK) - because Mobile 3.0 did not meet the conditions of the licence. It is not sure when a new licence will be issued. Meanwhile DVB-T carries on its success with LG planning to launch another handset model before Christmas.

In Switzerland, Take-up of the mobile TV service from Swisscom is not meeting expectations, according to Swisscom Broadcast chief Jean-Paul de Weck, speaking during the Biel Bienne Communication Days (Comdays). The main reason for the slow acceptance is the lack of choice of DVB-H capable handsets. Up until the end of September, the Nokia N77 was the only handset available to receive the service, though now there are four different models. Swisscom currently has about 5,000 mobile TV users, though it expects to gain more subscribers with the wider choice of handsets.

Qualcomm is now to give some more attention to its mobile TV standard of MediaFLO. This is because they no longer have to worry about UMB (see this). Outlining future strategies, Qualcomm indicated it's focusing more on its MediaFLO mobile broadcast TV and its Firethorn mobile banking technologies to carry it in the near term while it develops its Long Term Evolution (LTE) wireless infrastructure and its Snapdragon platform for future inroads in wireless mobile. MediaFLO is operated in 62 markets, but it's expected to get a boost in February when the big switchover to digital TV takes place. Qualcomm purchased $555 million worth of spectrum in the FCC's 700-MHz auction earlier this year, and the purchase will be used to spread MediaFLO. The new spectrum will enable the company to address 108 markets by the end of 2009, according to media reports.

Finaly for some good news:

A large U.S. television broadcaster has announced good results from recent trials in Chicago and Denver of mobile TV using a draft standard from the Advanced Television Systems Committee (ATSC). Ion Media Networks, Inc. said it found it relatively easy to set up two mobile channels in each city and reception was better than expected. The Open Mobile Video Coalition (OMVC), an alliance of local and national TV broadcasters, hopes to see members roll out commercial mobile TV services late next year. To date mobile TV services using other technologies have failed to deliver and grow a market among cellphone, notebook and car video users.

Ion Media's stations WCPX and KPXC have been multicasting two standard definition mobile channels since August. LG Electronics and Harris Corp., whose technology was selected for the ATSC standard, provided prototype mobile TV receivers and transmission equipment for the tests.

We're seeing fantastic reception out to as far as 40 miles from transmitters, and beyond that we have good transmission outdoors but it's not consistent indoors," reported Jenkins.

Reception was also good in cars at freeway speeds and indoors within 40 miles of transmitters. "We went into parking garages where there were three or four levels of concrete above us, and reception was perfect--that was one of the big technical lessons," said Jenkins.

Spectrum availability was not a problem in the trial. One station in the trial supports an existing high definition terrestrial broadcast, another supports multiple existing standard def channels.

UMB now officially dead, Long live LTE!

As one article put it, "Qualcomm cancels its own 4G system" going further to mention "Ultramobile broadband (UMB) is ultra dead". I blogged earlier about Nortel abandoning its CDMA business and about CDMA operators defecting to LTE and was sort of waiting for this imminent announcement to happen. There were already rumors about this happening since last year. (Not sure if some Hedge fund managers did be on this ;). UMB is also known as CDMA2000 EV-DO Rev C.

Qualcomm Inc officially announced that it has stopped development of Ultra Mobile Broadband (UMB), its next-generation, high-speed wireless technology, and has been making small-scale layoffs as it looks to cut costs in the weakening economy, Chief Executive Paul Jacobs said. Jacobs said the company was putting resources into LTE technology instead.

The company that created CDMA techology, meant for UMB to be CDMA’s 4G play. The company had high hopes for squeezing out WiMAX, positioning UMB to compete directly against LTE. With a logical upgrade path for existing CDMA carriers, UMB was designed to continue the GSM vs CDMA platform war in the fourth generation of wireless technology.

However, Qualcomm in recent years has gained dominance in the LTE development field as well. With Qualcomm now heavily invested in UMTS/HSPA technology, UMB had Qualcomm playing both sides, ensuring that they would be dominant in all CDMA-derived products (both UMB and LTE use technology originally derived from Qualcomm’s oldest CDMA patents).

With WiMAX becoming embraced, and even deployed, globally, UMB failed to gain a single carrier. The main cause for CDMA carriers defecting to WiMAX, has been Qualcomm’s monopoly on the technology. WiMAX trumps UMB in being an industry standard, not controlled or mandated by a single company.

The CDMA Development Group (CDG) has yet to comment on this announcement. However, the CDG has told that their driving force going forward will be to foster CDMA as a low-cost network option, especially in developing nations. Qualcomm still hopes to use CDMA for new networks in Africa, using their own hybrid GSM/UMTS/CDMA chipsets for international roaming when those customers travel abroad.

This leaves LTE as the eventual winner and with Operators already planning to roll out LTE network mid next year, WiMAX is going to get tough competetion from LTE. CDMA2000 operators meanwhile will have to now start planning how to move towards LTE (or WiMAX for that matter). 3GPP has laid down clear evolution path to move to LTE from CDMA2000. Other option which I quoted earlier is the eHRPD approach.

Mobile Phone Data and Statistics from 2007

In 2007, 1.15 billion mobile units were sold. Now according to Tomi in a post in Forum Oxford, these 1.15 Billion was split so that 805 million went to existing customers and only 300 million phones sold to new customers.

According to Informa, total number of subscribers worldwide increased by 600 million (from 2.7Billion in 2006 to 3.3 Billion in 2007) in 2007. This would mean that 300 million people got only SIM's and no phones. I am sure this would make green lobby a bit happy because people are recycling phones ;)

According to Informa, 28% of phone subscriptions in 2007 were multiple subscriptions (one person having more that one phone/SIM). In Europe this figure was approx. 50%.

This raises an interesting point; there is a big market for phones with dual SIM capability. It is not so simple though. There are no standards defining phone behaviour with dual SIMs. All the phones that I am aware of have a single transmitter/receiver. This means that even if you have two SIMs, they are both not active at the same time. You would have to manually choose which one is active at any point of time.

Manufacturing of dual SIM phones with two transmitter/receivers is possible but the phones will become slightly bulky and expensive. It can definitely make my life easier so I am all for them, dont know what others feel.

On the flipside, if you lose the phone you lose both your SIMs and are totally cut off till you get atleast one replaced.

We all want LTE now

One headline said, "T-Mobile International wants LTE fast" while the other said "LTE roll-out will accelerate despite recession, claims Motorola" and the third one screamed "Huawei To Launch First LTE Commercial Network In 2009".

I mentioned in an earlier post about attending LTE world summit this month. I am expecting some announcements and surprises in the conference where everyone would like to show off about their progress and readiness to launch LTE.

T-Mobile has announced recently that it plans to skip HSPA+ altogether and focus on LTE. It wants to roll out LTE network by 2010. The main reason for its decision stems from the fact that since MIMO is introduced in HSPA+, it wants to avoid the upgrade cost if LTE is available in couple of years. We have to remember though that HSPA+ is more of an upgrade to the existing HSPA and we can be assured of the reliability and the quality that we have so got used to. On the other hand, LTE may have its own problems and since it will be new technology, it would take time to mature. Can T-Mobile afford to go through this period of uncertainty and maturisation on its own without something to fall back on.

According to Ihab Ghattas, assistant president of Huawei Middle East, the Chinese telecommunications equipment and solutions provider plans to launch its first LTE/SAE commercial network in June 2009, providing LTE/SAE infrastructure to mobile operators.

Ghattas announced the decision in his report "Preparing for the future technology trends - LTE focus" at the meeting held by the SAMENA Telecommunications Council. He said the rapid development and benefits of wireless technology has seen mobile broadband evolve from UMTS/HSPA/HSPA+ to LTE, which offers more efficiency than other networks. Expectations are that by 2015 LTE subscriber base will reach 400 to 450 million, generating revenues of almost EUR150 billion.

Till date, NTT DoCoMo, China Mobile and Verizon wireless had announced to launch LTE/SAE based networks. Now we can add Huawei and T-Mobile to this list as well. Companies like Motorola and Nortel have not much HSPA/HSPA+ presence and have invested heavily in LTE, hoping to grab market share by the fact that they are there before others.

According to this another report, Operators relying on mobile or fixed/mobile broadband services to increase their future revenues are not only facing an upgrade of their wireless networks to HSPA+, WiMAX or LTE, but also a massive increase in the backhaul capacity needed to support that data traffic and multimedia applications.

Paul Steinberg, chief architect for Motorola’s wireless infrastructure products, reinforced the message this week, predicting that even 3.5G technologies will start to struggle soon in areas of high usage, and that this will force new approaches to backhaul as well as an early move to LTE, despite economic uncertainty.

In an interview with US-based CommsDay, Steinberg said 3G operators in developed markets will experience increases in data usage in the course of this year, ranging from sixfold to 14fold, but revenue from data services is growing only by 10-30% a year. This will push carriers towards all-IP, flat networks like WiMAX and LTE, with their improved cost of delivering broadband data.

Citing research by ComScore, Steinberg said that reasonable traffic profiles for mobile users by 2011 will range from 2.7Gb of data for typical handset users, to 11.1Gb a month for heavy users with both a laptop and handset. He believes some operators will have to start to roll out 4G-class networks as early as the end of next year to cope with the demands. Motorola is still relying on LTE deployments by six operators next year and 10 in 2010. However small their initial build-outs, Motorola points out that the 16 carriers that have committed to LTE in the next two years account for about 1.8bn subscribers worldwide, about half the global total.

According to Motorola, each LTE base station will require 200Mbps-300Mbps of backhaul capacity, which will stretch most fixed or wireless technologies apart from fiber or Gigabit Ethernet. This will lead to new approaches, such as ‘wireless fiber’ technologies, or relay techniques.

Get a Femtocell and make money

This post again is a concept but I dont see why the operators may not go this way.

The main reason you would put a Femtocell in your house or your shop is because you want cheaper calls and reliable coverage. The Femtocells would probably be setup as Closed Femtocells or better known in 3GPP Release 8 as CSG (closed subscriber groups). It may be beneficial for the operator that the Femtocells are setup as 'open' rather than closed. This can be useful in shops or malls where the shoppers can experience bad coverage in particular part of the shop or mall.

To motivate people to keep open access, they could offer free cash to the Femtocell owners on which outsiders (IMSI's not on the access list) camp and originate voice and data calls. In the web world, similar approach is used by Google Adsense. UK operator '3' has also tried similar cashback scheme before with decent success.

This approach may encourage lots of shops and people (especially during Credit Crunch scenario) to install Femtocells thereby increasing coverage significantly.

On the flipside, I should mention that people might start abusing this and increase the interference in the Macro cell. Also, the operators have to plan the Femtocell rollout in such a way that such interferences would be kept to minimum.

Will there be a winner in LTE and WiMax debate?

In the past there have been so many developments within WiMax and LTE in terms of where the two technology stands. Which technology is on the rise or which will eventually be a 4G technology is a never ending discussion.

On a regular basis I do get to know that either the LTE or WiMax camp claiming victory over another.

In a recent WiMAX World conference in Chicago, some advocates were quick to claim a WiMAX victory in the 4G technology race. The mantra or refrain for most of the sessions was that WiMAX is here and it's paving the way for 4G.

In the past few months there has been significant development in WiMax camp coordinated with the launch of WiMax services. In September Sprint-Nextel's launched the commercial mobile WiMAX service (called Xohm) in Baltimore. This definitely helped the buzz for WiMax to reach a new high. But as always together with the excitement, lies some anxious moments as everybody is now watching Xohm's debut to see how it fares with consumers.

There is no doubt that plenty of stake is riding on Sprint's Xohm launch. Clearwire also has got its own anxious moments with this launch as it was in last May that Clearwire announced it would merge with Sprint Nextel's WiMAX business to create a new company, also called Clearwire. The deal, which is expected to close by year-end, includes a $3.2 billion investment from Google, Intel, Comcast, Time Warner and others.

Although the above scenario really present a competitive and rosy picture for WiMax but even one of mobile WiMAX's biggest fans, admits that it's unlikely that WiMAX (or any one technology for e.g. LTE) will win the 4G debate.

In my view and so as I believe most of the people expects that the wireless industry will always have at least two technologies, perhaps more. My view can be supported with the idea of most of the operators going for HSPA+ technology. With operators eager to generate more revenue with the ever increased data rate requirements together with the delay in LTE there is no choice but to go for HSPA+. Which in my view has always been the best way to move forward as I am always a big fan of HSPA+ till LTE arrives?

This means that there may be some operators that will evolve along the HSPA+ path and never opt to deploy 4G or a 4G-like technology.

If the situation were to develop like I mentioned above then I don't think it is going to be as black and white as one (technology) wins and one loses. A lot of people don't realize that the most of the successful wireless operator or one of the most successful wireless operators today uses a technology that is only used by 13 percent of subscribers around the world.

But that's not all, inspite of all these and hence the Future of 4G will includes several interactive panels with experts who will delve into all aspects of the 4G debate. I am sure that whenever there is debate between LTE and WiMax it starts with the WiMax camp pointing out that Mobile WiMAX is the first out of the gate. Ok I agree then people argue that LTE is often considered the more evolutionary technology. The question probably isn't whether they can co-exist, they have enough common elements that it's feasible, it's whether there are enough reasons for them too.

So many times in the past including me has got into the debate of whether WiMax and LTE should or will be merged together?

In my past blog I have championed the cause of LTE and WiMax working together.
But as always there are many experts whoc belive that they ae going to work together. One of them is Peter Jarich, the research director of Current Analysys who firmly believe that LTE and WiMax are not going to merge. I can see where Pter is coming from because most of these phrases of working together are mostly biased towards politics and just from a political standpoint of getting all the parties together it's just not going to happen.
As I said in my previous blog regarding LTE and WiMax harmonization the guys have to fight it out. Now that might be bad for the carriers but it's good for the vendors who supply weapons to both sides and it's always good for consumers who get more choice.

Once thing which is quite clear though is that the presence of a rapidly maturing WiMAX ecosystem certainly has had the effect of accelerating LTE well before all the revenue potential was drawn out of HSPA and EVDO. In the past year LTE has certainly gained momentum in standards development, carrier decisions and an LTE wireless ecosystem being created. After all these significant developments in LTE analysts have started to believe that there is no reason to slow it down by merging it with WiMAX. There is, however, a reason for speeding it up to compete with WiMAX.

I can make a pretty strong argument that LTE would be at least four years later if WiMAX were not pulling it forward. WiMAX also comes with its own strengths that could add some intrigue to the battle. It's an IP standard from its base up and performs better in TDD and less mobile environments. LTE performs better in FDD and a high-user count model. That means the two could be complementary-albeit competing.

Would it be better if we had one technology and not two?

Well the debate continues……

CDMA Femtocell race heats up in USA

Airvana has said that its 'Betting the Farm' on femtocells in 2009. Recently it has entered a definitive supply agreement with Hitachi Communication Technologies, Ltd. ("Hitachi Com"). The agreement covers Airvana's HubBubT CDMA femtocell, Femtocell Service Manager, and Universal Access Gateway, and follows a joint development relationship announced in July 2008.

As part of the companies' previously announced joint-development agreement, Airvana has customized its HubBub CDMA femtocell, which is unique in the industry for its support of both 1x-RTT and EV-DO services; its Femtocell Service Manager, a scalable auto-configuration and remote management system; and its Universal Access Gateway, a carrier-class femtocell network gateway; to support the advanced features of Hitachi Com's Convergence Server. Under the terms of the agreement announced today, Hitachi will provide marketing, sales and support activities, primarily in the Japanese market, for the Airvana femtocell products. Delivery of the Airvana-Hitachi Com joint solution will provide operators with rapid deployment capabilities of advanced femtocell solutions. Hitachi's infrastructure equipment is used in networks serving more than 30 million Japanese CDMA and EV-DO subscribers.

According to Unstrung:

The company is slightly different from many others trying to crack the home base station market, in that it is developing both UMTS and CDMA boxes and pushing ahead with voice and data support straight out of the gate.

Airvana's main rival in the mini-CDMA field is Samsung Electronics Co. Ltd., which already has its Airave box in use at Sprint Nextel Corp. and possibly in tests at Verizon Wireless . Some analysts, however, expect that Verizon could also have its eye on Airvana's gear.

Competition is bit tougher on the GSM/UMTS side of the fence, involving everyone from established players such as Ericsson AB to well funded youngsters like RadioFrame Networks Inc. and ip.access Ltd.

Readers familiar with Airvana, however, will spot that although the technology is new [ed. note: sorta] the company's strategy for entering the market is the same as it took with 3G CDMA infrastructure: Partner with the big boys and gals and supply them with the technology that carriers end up using in their networks.

In other news, Tatara Systems Inc. is going full steam ahead for femtocells now that it has sold its mobile broadband business to Smith Micro Software Inc.

Now, femto-focused Tatara will use the money from this sale to develop its convergence gateway product used in the femto gateways that will sit in the network between the femtocell access points and the mobile core. In IMS networks, Tatara's convergence gateway acts as an SIP-application server.

According to a press release last month:

Ericsson and Tatara, the leaders in SIP-based network integration and femtocell convergence, have successfully demonstrated this solution, which enables CDMA network operators to cost effectively integrate femtocells into their IMS networks. This provides both enterprises and home subscribers in-building service levels that meet or exceed the service levels and voice quality of macro networks, while enabling improved economics and delivery of advanced services.

The solution combines Ericsson’s IMS Core Network infrastructure with a SIP-based femtocell and the Tatara Convergence Server (TCS) for CDMA-1xRTT.
