FMC just a Hype?

According to Yankee group report, FMC is just a hype and its now fading.

Yankee Group revealed that fixed-mobile convergence (FMC) has strong potential to shake up the communications market for enterprise voice and mobility, but focus must shift from cost-savings to productivity in order for adoption to take-off. Today, FMC is sold with a focus on reducing cost for the enterprise, but with the subtext of productivity benefits for the end user. A consequence of this feature-focused approach is that FMC will not be the growth driver many carriers expect. Instead, it will be a necessary feature in carrier portfolios.

According to the recently published Yankee Group Note, Productivity Is the Prettier Face of FMC, enterprise adoption of FMC remains low. According to the Yankee Group Anywhere Enterprise—Large: 2007 European Fixed-Mobile Convergence Survey, only 2% of enterprises have deployed FMC. This number is even lower in the US and Canada. Competition from alternative mobility initiatives, technological immaturity and reduced priority placed on voice communications by IT decision-makers have contributed to this perception and low adoption rate. In addition, 29% of IT decision-makers surveyed in the Yankee Group Anywhere Enterprise—Large: 2007 US Fixed-Mobile Convergence Survey consider the technology nice to have, but not a critical application on their IT/networking road map. When combined with an adoption rate of less than 2%, this statistic does not bode well for FMC as it is currently configured and marketed.

"The FMC hype was a bit premature, but the day is not far off when FMC will play a major role in the way many people work," said Brian Kotlyar, research associate in Yankee Group's Enterprise Research group. "Integrating voice into mobile applications will be the new frontier for FMC. This will enable true differentiation between the FMC offerings of today that revolve exclusively around voice and the FMC applications of tomorrow that will enrich mobile data and increase Anywhere Enterprise™ productivity."

According to Telecommunications online (worth reading), During its short lifespan fixed-mobile convergence has gone from the greatest idea since bread was sliced to overhyped nonsense that will never happen. Along the way, it has still managed to maintain a small degree of respectability and potential.

From a report by MCF Corporation:

As deployment of 3G networks continues to grow, applications built for mobile entertainment should become more ubiquitous. According to Juniper Research, the value of the mobile entertainment market, including music, games, TV, sports and infotainment, gambling and adult content, could increase to nearly $77 billion by 2011 from $17.3 billion in 2006. Included in this forecast is the 50.2% CAGR of the mobile game
market by 2009 (to $10.9 billion from $3.1 billion in 2006). While one could argue the potential size of the mobile entertainment market, we believe that the transition to data has begun in an effort to reduce churn rates, preserve ARPU, and extend carrier brands.


The following highlights a few of the drivers:

Mobile entertainment and content. As deployment of 3G networks continues to grow, applications built for mobile entertainment should become more ubiquitous.

Included in this forecast is the 50.2% CAGR of the mobile game market by 2009 (to $10.9 billion from $3.1 billion in 2006). While one could argue the potential size of the mobile entertainment market, we believe that the transition to data has begun in an effort to reduce churn rates, preserve ARPU, and extend carrier brands.

Location-based services (LBS): LBS is quickly emerging as a benchmark for service differentiation among mobile operators. According to ABI Research, GPS penetration in handsets could reach 1 billion by 2010 while Berg Insight projects 83% LBS growth in Europe, reaching a €5 billion market by 2010. We continue to expect LBS to be utilized for navigation, management/ tracking of assets, information (for example, mobile yellow pages) and emergency services. We are initially focusing on companies that offer machine-to-machine (M2M) applications which allow enterprises and consumers the ability to monitor and manage many types of assets (industrial vehicles, rental car fleets, real estate) in an effort to reduce costs and more efficiently operate.

Converged mobile devices, applications and services: According to IDC, the worldwide market for converged mobile devices increased 42% during 2006, reaching 80.5 million units, and is expected to cumulatively reach more than 1 billion units by 2011. Growth in shipments is primarily due to a greater selection of devices from which to choose and lower price points as mobile carriers look to differentiate their services. Many of these devices offer multiple features such as embedded cameras, MP3 players, GPS capability, and expended memory slots which allow subscribers the ability to carry only one device. We view the introduction of devices such as the iPhone as driving wireless data usage.

At the end of 1Q07, there were 2.8 billion wireless subscribers worldwide,
of which approximately 6%, or 172 million, were 3G subscribers. The 24% CAGR of total subscribers during the past four years has been driven by the rapid deployment of networks, availability and affordability of handsets, along with the introduction of new 3G services. We estimate 3G subscribers will grow at a 55% CAGR through 2010, reaching 652 million (approximately 14%) total estimated subscribers. We believe that wireless technology allows enterprises to become more efficient operators due to the lower costs to deploy and operate, comparable capacity to wireline solutions, increased functionality and productivity, and ability to track personnel and assets.

The chart above illustrates how data ARPU has stabilized total ARPU for AT&T Wireless/Cingular ($48-50 range), which has more than 62 million subscribers. AT&T currently reports approximately 33 million data customers (up more than 30% Y/Y) the growth of which has begun to reflect wider usage of its new 3G UMTS/HSDPA network (current coverage in 165 cities and is on schedule to cover virtually all of the top 100 U.S. markets by the end of 2007). The trend of wireless data
growth offsetting decreases in total ARPU is clearly evident below and is occurring throughout the industry.

MBMS but no Multicast

From the discussions going on in the industry, it seems that MBMS is being implemented by everyone but no one is concentrating on Multicast. This means we should now change MBMS to MBS but ofcourse it doesnt sound as good ;).

In the discussions going in RAN5 on the testing side, Nokia, Qualcomm and Ericsson has indicated that they are not interested in Multicast at the meoment (and probably for long time) and Mobile TV using MBMS will only be using Broadcast services.

The main reason for Multicast not being implemented is that it is quite complex and the purpose it was designed to serve can be served by using authentication at the Application Layer which i think is far enough.

Frankly if operators are really interested in utilising the potential of MBMS (excluding Mobile TV) then they will have to use Multicast sooner or later.

Can anyone think of why Multicast would be better than application layer security?

IMS Updates

Ericsson and Vodafone launched an IMS network in Czech republic this week. Under an agreement signed earlier this year, Ericsson was responsible for delivery and systems integration of its advanced IMS solution, along with project management, network design and implementation. With Ericsson's IMS solution, Vodafone Czech Republic can offer a wide range of next-generation IP telephony and multimedia services towards both fixed and mobile users. It said IMS is an important step towards fixed-mobile convergence. The international-standards-based technology is highly scalable, takes care of connection control, and ensures service quality as well as network and service security.

Aricent, a full-service, full-spectrum communications Software Company, announced this week that it has joined the IMS Forum, the industry's only forum dedicated to the acceleration of IP Multimedia Subsystem (IMS) application and service interoperability. Aricent has a dedicated IMS practice, with more than 800 person years of experience, offering an extensive portfolio of IMS software services and products. The services range from initial strategy and design, through software implementation to system integration and testing for the entire IMS architecture. These services accelerate time-to-revenue for Aricent clients and reduce their risks when deploying IMS-based solutions. With a comprehensive portfolio of IMS software services and products Aricent enables communications equipment manufacturers, device manufacturers and service providers to significantly reduce their time–to-market and mitigate the risks associated with IMS migration and roll-out.

Meanwhile, The IMS Forum, the industry's only Forum delivering IMS services interoperability verification and certification, announced recently that they have signed an MOU with the International Multimedia Telecommunications Consortium (IMTC), an international alliance of companies working together to improve the customer experience and accelerate market adoption of content delivery and unified communications solutions through interoperability of products and services based on open standards. The IMS Forum focuses on interoperability at the IMS Applications and Services Layer across mobile, fixed and cable broadband networks. The IMTC IMS Activity Group focuses on issues surrounding IMS Client interoperability, development and providing feedback to standards organizations.

Under the terms of the agreement, the IMS Forum and the IMTC will establish both a technical liaison between their Technical Working Groups and a marketing liaison. Through these liaisons the two groups will exchange technical information on IMS specifications, testing and interoperability, share interoperability testing best practices, collaborate on technical documents, and organize and participate in future joint testing events. The marketing liaison between the Marketing Working Groups will allow the organizations to share the results of their joint activities with the industry as well as promote this technology's adoption.

On Header Compression

Was doing some digging into pre-ROHC compression techniques and here they are:

Van Jacobson header compression (VJHC) (RFC 1144) is based on delta coding. The differences between two packet headers are referred to as the “delta”. Instead of transmitting the entire header, VJHC transmits only the delta. This approach achieves high compression. On the downside, it introduces vulnerability. If only one delta coded header is corrupted, all the following packets are erroneous. To recover from these errors and re–establish the current base header, VJHC sends all TCP re–transmissions uncompressed. Thus, VJHC does not require any signaling between compressor and decompressor. The disadvantage is the sensitivity to error–prone links. The Van Jacobson compression scheme was developed to increase the performance of IP/TCP flows over low bandwidth links such as PSTN. It does not even support compression of IP/UDP flows since at that time UDP traffic was very low. This scheme uses delta compression, sending only the difference in the value of the changing fields, to minimize the number of bits sent. It achieves compression from 40 bytes to on an average 4 bytes. It relies on the TCP recovery mechanism to recover from errors in the context due to bit errors and residual errors due to packet loss on the link. This scheme is obviously unsuitable for wireless links and multimedia applications.

Robustness at the cost of less compression was introduced by Perkins and Mutka. In “Dependency Removal for Transport Protocol Header Compression over Noisy Channels,” The delta–coding for the adjacent packets has been replaced by a reference frame. Several consecutive packets are aggregated to a frame. The first packet of a frame is sent uncompressed and the following packets use delta coding with respect to the first (uncompressed) packet in the frame. Clearly, the differences to packets at the end of a frame are larger than for those at the beginning. The compression gain is thus limited (and lower than for VJHC). The advantage of this approach is the usage of shorter delta coding ranges. Corrupted packets do not necessarily lead to the loss of synchronization. This is a clear advantage over VJHC.

IP Header Compression (IPHC) provides a number of extensions to VJHC. The most important extensions are support for UDP, IPv6, and additional TCP features (RFC 2507). With the explicit support of UDP come additional features, such as multicast. Nevertheless, support for RTP is still not given which makes the scheme unsuitable for many multimedia applications. Similar to VJHC, IPHC relies on the change of header fields as well as on the derivation of header field contents. The encoding also employs the delta–scheme, transmitting only the changes in the header fields.

The Compressed Real Time Protocol (CRTP) scheme presented in RFC2508 compresses the 40 bytes header of IP to 4 bytes if the UDP checksum is enabled, or to 2 bytes if it is not. This is possible by compressing the RTP/UDP/IP headers together, similar to the VJHC approach. With the characteristics of the RTP protocol, the changes for the RTP header fields become partially predictable. In addition, changes in some fields are constant over long periods of time. Thus, the expected change in these fields can be implied without even transmitting the differences. These implied fields are also referred to as first order changes. They are stored with the general context for each specific connection. The differences within fields that have to be compressed are referred to as second order differences. An example for these are video frame skips. Video frames are generally transmitted every 40 ms. In case a frame cannot be encoded (e.g., due to lack of processing power or because of a slower play-out ratio), the implied time no longer is accurate. Therefore, the new first order is set to the second order and the connection context is updated. CRTP cannot use a repair mechanism as VJHC does because UDP/RTP are unidirectional protocols without retransmissions.

RObust Checksum–based COmpression (ROCCO) is a refinement of CRTP. ROCCO includes a checksum over the original (uncompressed) header in the compressed header. The checksum facilitates local recovery of the synchronization. In addition, ROCCO incorporates compression profiles (tailored for specific applications, e.g., audio or video streaming) and has a code with hints on the change of header fields in the compressed header. These mechanisms improve the header compression performance, especially for highly error–prone links and long round trip times

MBMS battle heats up

The MBMS battle has started heating up with new developments and announcements nearly every week.

First of all there was this announcement from ZTE, China

China's ZTE Corp. announced that it has, in collaboration with Qualcomm, successfully completed a Multimedia Broadcast Multicast Service (MBMS) testing based on the 3GPP R6 standard conducted at its Shanghai R&D center last month.

The first testing MBMS inter-operability test (IOT) completed, test results show that 128- and 256Kbps high-speed transmission of MBMS TV programs broadcast and multicast services can be smoothly delivered over cellular networks. The success of MBMS IOT marks the readiness of commercial delivery to the mass market.

"Qualcomm is happy to cooperate with ZTE in conducting the MBMS testing, an area which we believe is part of the core development of ZTE's W-CDMA products," said Frank Meng, president of Qualcomm Greater China. "This is a major contribution in the development of MBMS and we are confident that the results of the testing will help our customers provide more competitive W-CDMA products and solutions moving forward."

Then yesterday, Anite submitted first MBMS Conformance Test which they were able to pass on Nokia NoRM-6 and Qualcomm 7200 UE. Other System Simulator manufacturers are not far behind with Anritsu and R&S also focussing heavily on MBMS test cases development.



Anritsu Protocol Test System (PTS) is shown in the figure above.

At present it seems Nokia and Qualcomm are leading the way on the UE side but in past i have heard about Ericsson and Motorola being MBMS ready soon.

ROHC, compressing IP headers over air interface

In an All-IP network, when IP packets are transmitted over the air, it would make more sense to strip down the headers as headers could be as big as the data being transmitted and these headers are overhead wasting the precious air resource. To help compress these headers, RObust Header Compression was standardised. Infact ROHC is not the only header compression scheme and i will post a bit more information in my future posts on which scehemes are available and why ROHC is used.

The diagram above shows the basic ROHC principle. It shows that ROHC compresseor is used before the data is sent over the air and decompressor at the receiving end adds the uncompressed headers back to the received packets. As expected, ROHC only works if both the ends have ROHC protocol.

A typical header compression is shown in the diagram above.

More information is available at the 3G4G website.

Back to work

Had been enjoying the sun in sunny Istanbul for a week now and back to work to find over 200 mails in my different Inboxes. Will take some time for me to get back to the routine.

By the way, the photo is taken just outside Blue Mosque (known as Sultanahmet).

More on Continuous Packet Connectivity (CPC)

Just realised that CPC is becoming more important with the Network Operators and UE manufacturers because it can allow more UE's to be ready for transmitting data. In my earlier post i had given some details about CPC.

Before i could begin writing some more details on CPC, i came across Martin's Blog which have excellent information on this topic. So i have listed them down here:

Continuous Packet Connectivity (CPC) Is Not Sexy - Part 1

Continuous Packet Connectivity (CPC) Is Not Sexy - Part 2

Continuous Packet Connectivity (CPC) Is Not Sexy - Part 3

There might be a part 3 coming soon, which will make life simpler for people like . Any additional information in form of comments most welcome.

Added on the 14th of Jan 2009.
Part 3 has now added to the same post...

WiMAX on display

Vodafone has deployed WiMAX technology in Malta. The island (population 400,000) is one of Vodafone's smallest markets.

The supplier of the network, Airspan, announced in June that Vodafone Malta had deployed its HiperMAX 80216d 'fixed' WiMAX base stations and CPE to offer bundled mobile, fixed voice, and data services to residential and business customers. Since that announcement was made, Vodafone has joined the lead industry organisation promoting and steering WiMAX development, the WiMAX Forum.

According to Pyramid research, "Vodafone, owing to its scale, is an agent of change in the operator community and we expect others to follow its trajectory. With operators present in different markets and looking for new revenue sources, there is no 'one-size-fits-all' technology, but the wrong technology can set an operator back years."

The research firm adds that "in catering to the needs of different markets and customer segments, operator networks will comprise diverse access technologies, each optimised for certain geographies, demographics, and services. For the WiMAX champions this is good news; for LTE backers it is a strong warning that should lead to increased R&D budgets for the next few years—in both camps.


In other news, Samsung Electronics will demonstrate the next generation telecommunications technologies at its annual international forum, which will shed light on what they call as global 4G technologies and gadgets.

This year’s Samsung 4G Forum will draw more than 130 influential industry leaders and service providers from 26 countries. It will mark the first time that all three candidate 4G technology _ IEEE 802.16m (Mobile WiMAX), 3GPP2 Ultra Mobile Broadband (UMB) and 3GPP Long Term Evolution (LTE) _ will be seen with each other.Each of the 4G technologies has a head cheerleader, with Intel supporting WiMAX, Ericsson touting LTE and Qualcomm preferring UMB. IEEE 802.16m WiMAX, UMB and LTE are expected to be initially implemented in 2010.

I think for companies like Samsung to break into new markets, its very important to use the term 4G. Lets hope that they all succeed.

Mobile TV via Satellite

A heading of news article yesterday read: "European mobile operators are looking for economic ways of launching broadcast mobile TV services directly to handsets". This made me wonder, if there is a strong case for Mobile TV via Satellite?

Couple of days back, 3 Italia reported that it had 719,000 people using its DVB-H service by August 22, which is about 9.4 percent of its 7.68 million customer base reports Dow Jones in Italian. The figure is a good sign—at the beginning of June it was 600,000 and back in March it was 250,000, or about 3.7 percent of the subscriber base. So this proves that some people are using Mobile TV if available.

The only popular satellite Mobile TV i am aware of being used practically (please correct me if you know more) is the S-DMB being used in Korea.

According to a report in Moconews, currently some 7 million people in S. Korea are watching mobile TV--that equates to one in every seven residents of the country--but none of the operators offering DMB services has yet to make any money. Each of the six terrestrial DMB operators has piled up an accumulated loss of between $22 million and $33 million. The only mobile TV operator that charges for its service is SK Telecom-owned TU Media, which offers its DMB service over a satellite-based system (S-DMB). It has 1.2 million paid subscribers, but TU says it needs at least 2.5 million to break even in operation. That’s before it can even start to recoup its $435 million investment in satellites and networks.

The European Space Agency (ESA) has joined the DVB-H party by funding development of technologies for broadcasting TV to mobiles via satellite. ESA has called its standard DVB-SH (Digital Video Broadcast - Satellite, Handheld) and envisages using satellites to send out video at 2GHz to 4GHz (S-Band). Terrestrial repeaters would be used to give indoor coverage. Eutelsat has commissioned a new satellite to be launched in 2009, with the intention of broadcasting DVB-SHb - though it's hedging its bets by claiming it's for multimedia distribution rather than any specific technology or application. Much of the technology needed by DVB-SH doesn't yet exist, so the ESA will be issuing invitations to tender (ITT) for companies that want to have a go at developing them. First up will be a mobile chipset capable of receiving and decoding DVB-SH version b signals. The ITT is due to be published in the next few months.

Finally i found a good report on BetaNews detailing the pros and cons of Satellite Mobile TV:

It's an ambitious idea, and it's not nearly a done deal. But yesterday, a proposal was introduced before the European Parliament for a timetable by which the EU would select a few choice service providers, for the precious and narrow spectrum it will be making available for the entire continent. It will require the consent and cooperation of all 27 member states - something the EU rarely gets even with less ambitious proposals.

Here's what it means: Last February, the EU established two small chunks of radio spectrum - 1980-2010 MHz and 2170-2200 MHz - as reserve space for future MSS broadcasting. Under normal EU law, member states would each have the right to select their own service providers for satellite TV and radio service for their respective countries. In fact, if the EU were to change its mind now and do nothing, that's what EU states would do next.

But there's two big problems: First of all, no single EU country is very big, geographically speaking, compared to the whole of Europe. A satellite signal covers a very broad portion of the Earth, so any service provider licensed for, say, France could probably have its signal picked up in southern Finland. Simply put, the laws of physics dictate a wide coverage area that technology cannot circumvent...unless every mobile TV receiver in Europe were custom-built for each member country. (If you're thinking like a manufacturer of DVD consoles, you might not be too opposed to trying that.)

Even if France's signal and England's and Bulgaria's and all the others could be picked up everywhere else - which, if you think about it, will be the case anyway - Bulgaria's service provider wouldn't want its signal overlapping England's. And that leads us to the second big problem: There's not enough MSS spectrum available in the 2 GHz band to go around.

So the European Union is stepping in, or at least attempting to. But in order for member states to allow it to do so, it has to formally present its case to those states for why it has the authority to do so. Imagine if, under a different style of US constitution, in order for the federal government to make its case for regulating the public airwaves, it had to get all 50 states' consent to giving up their own rights to do so individually.
Thus a large part of the EU proposal yesterday explains - as it must do under European law - why it's claiming the authority to propose a national selection process for MSS providers.

For its claim to qualify as valid, it has to meet two tests under the EU constitution. First, the claim must meet the Subsidiarity Principle: essentially, that the nature of the job at hand means it can be performed better by the EU than by all the 27 states acting independently. In other words, the EU has to prove it can do the job not because it's better at these sorts of things, but because the problem at hand makes a single body better suited to the task.

Here is where the EU has physics on its side: Satellite signals cover broad territory, and states' boundaries do not. "Selection and issuance of rights over the same spectrum to different satellite operators in different Member States would prevent satellites from covering their natural footprint," the EU proposal reads, "which by nature covers a large number of countries; it would risk fragmenting the satellite communications market and eliminate the natural advantage of satellites compared to other modes of communication. The mobile character of the services involved also means that citizens travelling in the EU should benefit from the availability of such services throughout the EU."

Second, the EU's case must meet the Proportionality Principle. This means it can't claim more authority than it needs to do the job...and once the job is done, it steps out of the way. In other words, it can't appoint a permanent commission like the FCC.

In making that part of the case, the EU goes on, "The proposal will create a mechanism for coordinating the selection and definition of certain conditions to be attached to rights of use of spectrum. It will not touch upon the right of Member States to grant the authorizations to use the spectrum or to attach specific conditions applying to the provision of services in areas which are not harmonized. Member States will be closely involved in elaborating the details of the selection procedure."

Here is where critics say the EU's case may fall apart. In order to win the authority to drive the MSS adoption process, the EU is limiting itself to driving the selection process for prospective service providers. Once that job is done, it's leaving it up to member states to apportion per-country licenses to those companies, for channels which the EU would already have selected as well.

On the one hand, it doesn't make sense. In order to sell its plan, the EU is leaving open the option for member states to deny licenses. But assuming a state does so, how could it block the reception of a signal from a service provider whose license was denied? That might take a technological solution...which brings up the whole "per-country" manufacturing option for MSS receivers again.

On the other hand, only such a hare-brained scheme might just work, because member states don't want to be perceived by their citizens as ceding any part of their authority to a federal institution. Giving them the right to say "no" could be a kind of ceremonial concession, not unlike the establishment of a constitutional monarchy where the monarch is essentially a face on a coin - which is a state of affairs not unfamiliar to member states.

"Since industry so far could not agree on a single standard for mobile TV, commercial launches of mobile TV are delayed," reads a statement from the EU's central authority in Brussels last month. "Europe's competitors, most notably from Asia, have made significant progress - partly due to state intervention - and Europe risks losing its competitive edge unless sufficient momentum is achieved. This is why there is a need to develop a 'blueprint' for mobile TV in Europe."

Is UMB the same as LTE

Recently i have come across press releases trying to sell UMB (Ultra Mobile Broadband) as 4G technology. This is the same as trying to sell LTE and mobile -WiMAX as a 4G technology.

IMT has taken a clever approach and instead of calling the successor of 3G as 4G, they are calling it IMT-Advanced.

The main requirements for 4G are as follows:

• Peak data rate of 100Mbps for high mobility applications such as mobile access
• Approx. 1Gbps for low mobility applications such as nomadic/local wireless access

Doing some digging on the UMB topic, i realised that it is the same as LTE but an evolution from CDMA2000. This is being standardised by 3GPP2.

Some of the key features (and comparing it with LTE) includes:

• It used OFDMA based air interface (same as LTE)
• It supports FDD (LTE supports FDD and TDD and a combination of them so i am not sure if UMB only supports FDD)
• Scalable b/w of 1.25MHz to 20MHz (same as LTE)
• MIMO and Beamforming (Same as LTE but UMB also supports 4x4 antennas whereas LTE supports 2x2)
• Data speeds upto 275Mbps in DL and 75Mbps in UL (LTE has 144Mbps in DL and 57Mbps in UL but that is because of 2x2 MIMO)

Since the term 4G is already being abused so much, one option is to let people use 4G as they wish and then when IMT-Advanced is available, start calling it 5G. What do you think?

XOHM = ZOOM + ROAM

Sprint (US) is getting ready to unleash a WiMAX network unto the masses. The quirky news is that they've decided to name it XOHM. The 4G high-speed data network will be based on WiMAX technology, and they plan on sharing the network with Clearwire.

By the end of 2008, the XOHM (pronounced "zoam"... sort of like a zoom-roam hybrid) network will be able to reach 100 million people. If everything goes according to plan, this number will expand to 125 million by the end of 2010. The initial building of the infrastructure will cost Sprint about $2.5 billion.

The first cities to experience XOHM will be Chicago, Baltimore, and Washington when they get their hands on the soft launch at the end of this year. The full commercial WiMAX launch is scheduled for "the first half of 2008."

In another announcement, Sprint Nextel Corp., the third largest US wireless service firm, has announced plans to spend nearly $5 billion by the end of 2010 on a new network based on the emerging high-speed wireless technology known as WiMax, Reuters reported. The company said that it expects spending on the network through the end of 2008 to be at the low end of its previously announced estimates due to its agreement to connect its network with Clearwire Corp., a small wireless service provider. Sprint said it expects to spend $2.5 billion on the network through the end of 2008 compared with its earlier estimate of $2.5 billion to $3 billion. Sprint expects to reach a potential 100 million customers in that time, with the company providing coverage to 70 million people and Clearwire covering 30 million people.

Prepare for WiMAX 2.0

I was completely unaware of IEEE 802.16m which is promising speeds upto 1Gbps. Only when someone asked me what my opinion was on this i did some digging in this.


IEEE 802.16m promises to deliver speeds up to 1Gbps and be backward compatible with 802.16e-2005 (mobile WiMAX) solutions. The 802.16m group should wrap up the technology development phase in 2007. Similar to existing mobile WiMAX, 802.16m will use multiple-input/multiple-output (MIMO) antenna technology. The idea with 802.16m, though, is to increase bandwidth by using larger MIMO antenna arrays.


The 802.1m group is targeting ratification and finalization of the standard by late 2009. So, we’re still a couple of years (or more) from having a gigabit version of WiMAX. As compared to other IEEE 802 standards development, such as 802.11, this is an aggressive schedule. In my opinion, these will be difficult dates to hit, especially with the requirement for being backward compatible with 802.16e-2005.


The advantage of 802.11m to cellular companies is that it could allow the convergence of 3G and 802.16 into a single 4G technology for mobile and fixed applications. This would enable cellular companies to offer service, such as IPTV and VoIP, as effectively over wireless connections as they are today on wired networks. This would lead to competition with existing fixed wireless broadband services currently delivered over cable and telephone lines.


Many vendor sources however, have expressed some skepticism about the speed with the work can be completed (the end of 2009 is being mooted as a baked date) and the chances of maintaining backwards compatibility with mobile 802.16 technology. Some folks worry that carriers have unrealistic expectations on how fast new WiMax profiles and interfaces can be developed. "They just walk in, snap their fingers, and expect it to happen," one industry source told us on the show floor yesterday. After all, it took several years for the IEEE to arrive at a satisfactory fixed broadband wireless specification in the form of 802.16d and even longer for the WiMAX Forum to certify interoperability between products using the technology.


Martin has some interesting analysis on his Mobile technology page:


Between today and WiMAX II, there's systems such as WiMAX and LTE which promise faster data rates than those available today by mainly doing the following:

• Increase the channel bandwidth: HSDPA uses a 5 MHz channel today. WiMAX and LTE have flexible channel bandwidths from 1.25 to 20 MHz (Note: The fastest WiMAX profile currently only uses a 10 MHz channel today for the simple reason that 20 MHz of spectrum is hard to come by). So by using a channel that is four times as broad as today, data rates can be increased four times.
• Multiple Input, Multiple Output (MIMO): Here, multiple antennas at both the transmitting and receiving end are used to send independent data streams over each antenna. This is possible as signals bounce of buildings, trees and other obstacles and thus form independent data paths. Both LTE and WiMAX currently foresee 2 transmitting and 2 receiving antennas (2x2 Mimo). In the best case this doubles data rates.
• Higher Order Modulation: While HSDPA uses 16QAM modulation that packs 4 bits into a single transmission step, WiMAX and LTE will use 64QAM modulation under ideal transmission conditions which packs 6 bits into a single transmission step.

By using the techniques above, LTE and WIMAX will be able to increase today's 2 MBit/s to about 20-25 MBit/s. That's still far away from the envisaged 1.000 GBit/s. To see how to get there let's take a look at what NTT DoCoMo is doing in their research labs, as they have already achieved 5 GBit/s on the air interface and have been a bit more open at what they are doing (see
here and especially here):

• Again increase of the channel bandwidth: They use a 100 MHz channel for their system. That's 4 times wider than the biggest channel bandwidth foreseen for LTE and 20 times wider than used for today's HSDPA. Note that in practice it might be quite difficult to find such large channels in the already congested radio bands.
• 12x12 MIMO: Instead of 2 transmit and receive antennas, DoCoMo uses 12 for their experiments. Current designers of mobile devices already have a lot of trouble finding space for 2 antennas so a 12x12 system should be a bit tricky to put into small devices.
• A new modulation scheme: VSF spread OFDM. This one's a bit mind bogelling using CDMA and OFDM in combination. Wikipedia contains a description of something called VSF-OFCDM which might be a close brother.

GSM/UMTS Growing faster than other technologies

According to 3G Americas press release:

A total of 564.6 million new subscriptions to GSM/UMTS services worldwide in the twelve months ending in June, with almost 18% of these from the Western Hemisphere alone, according to the estimates of Informa's World Cellular Information Service. GSM/UMTS added nearly 100 million subscriptions in the Americas during this time period, more new subscriptions than any other technology. GSM/UMTS continues to lead the wireless market of Latin America and the Caribbean, where nearly 22 million GSM users were added in 2Q 2007, increasing GSM market share in the region to 74%.

GSM is not only the leading industry standard for reliable wireless voice communication with more than 2.5 billion customers, but also plays an integral role in 3G as more than two thirds of the estimated 200 million 3G users across the globe use UMTS/HSPA technology for mobile broadband. There are currently 181 UMTS operators in service across 77 countries, with an additional 72 networks planned, in deployment, or in trial. Of those 181 operators, 135 have enhanced service with HSDPA, with 80 additional HSDPA networks planned. Five operators across the world have launched HSUPA technology to date, and over 130 more operators plan to upgrade with HSUPA, many in the second half of 2007.

GSM technologies account for 85% of mobile wireless customers globally. More than half a billion new subscriptions to the GSM family in the past twelve months ending June 2007 represent a worldwide growth rate of 29.5%. Focusing on the Western Hemisphere, GSM holds nearly a 60% share of market, with a subscriber base of 358 million GSM/UMTS customers, compared to 191 million for CDMA. In Latin America and the Caribbean, there are 340 million total wireless users, and of these, 253 million use GSM, which now holds a market share of 74% in the region, up from 62% one year ago.

Erasmo Rojas, Director of Latin America and the Caribbean for 3G Americas stated, “The growth in the uptake of GSM/EDGE/UMTS technologies in Latin America continues to progress. Wireless service providers are achieving great results in increased contribution to their Average Revenue Per User (ARPU) from wireless data services through their deployment of EDGE and now recently UMTS/HSDPA.” He continued, “As of June 2007, typical operator ARPU from wireless data value-added services represents more than 15% of total wireless revenue in countries such as Mexico (15%), Ecuador (20%), Argentina (24%) and Venezuela (24%).”

'3' starts MBMS trials

The mobile operator '3' has again taken a major step forward by starting Mobile-TV trials using Multimedia Broadcast Multicast Service (MBMS). The trials are in conjunction with Ericsson. The following from the press release:

3 Italy uses DVB-H for its Mobile TV offering. However, MBMS is being developed under the auspices of the global 3GPP standards body.

MBMS uses existing 3G networks and spectrum for content delivery, building on existing infrastructure. To deliver MBMS, upgrades are made to the existing network as well as content and broadcast servers. 3G mobile phones with support for MBMS are expected to be available in 2008, said the company.

MBMS is a different approach to Mobile TV combining both broadcast and unicast shows (though multicast is more accurate). It also gives consumers opportunity to interact by voting, sending messages, accessing downloads of related content and special promotions from advertisers.

"MBMS as part of the 3G evolution is an attractive technology not only because of its flexibility and efficiency, but because it's quick and easy to deploy and leverages existing infrastructure," said Kursten Leins, Strategic Marketing Manager - Multimedia, Ericsson. "MBMS allows an unlimited number of users to watch the same mobile TV program at the same time in the same area, as well as enabling valuable user interaction with advertisements, campaigns and programs."

"3 pioneered 3G in Australia, so it was a great opportunity to see the country's first MBMS technology trial run on Australia's first 3G network," Leins added. Since the MBMS signal can be pin pointed to specific geographies, it's also possible to broadcast different mobile TV programs to different areas, giving a locally-specific customer experience and also providing highly targeted mobile advertising opportunities.

"We are very happy with the trial - the technology worked well and apart from delivering a good customer experience, it's extremely efficient in terms of network traffic and capacity, and provides new levels of customer involvement with their programs," said Michael Young, Director Technology & Services, 3 Australia.

The technical trial was held in 3's Sydney Head office over 6 weeks and run by Ericsson who developed the trial system. Using four specially designed prototype handsets, Ericsson also installed equipment to simulate the content and broadcast servers on a section of 3's network so the customer and network experience could be seen.

"The trial has been very interesting, and we'll continue to work with Ericsson to keep a close eye on the technology and the handsets to support MBMS as they develop," Young added.

Beginning of the Cablefree world

With UWB becoming popular and more devices about to be rolled out, the cable connections between TV, VCR, DVD players, Camcorders, etc can be a thing of past.

In UK, OFCOM removed the restrictions for the use of UWB devices upto a range of 30 metres. In the US and Japan, UWB home hubs are a popular way of sharing domestic broadband.

Ultra-Wideband (UWB) can be used to send huge amounts of information between electronic devices, making it suitable for connecting items such as digital TV decoders and DVD players to television sets, or digital cameras to computers.

It could also be used to wirelessly link satellite dishes or cable TV connections to set-top boxes, doing away with the need for cables to be poked through walls and run around skirting boards. Satellite broadcaster Sky, for instance, is understood to be looking at whether UWB could be integrated into its equipment.

Described by techies as "Bluetooth on steroids", UWB can operate over distances of up to 30 metres. Japanese electronics manufacturers are already producing modems that use UWB, while Cambridge-based chip maker ARM Holdings has deals with several companies that plan to make UWB devices.

Separately, Vodafone yesterday joined the Wimax Forum which is creating standards and specifications for a new longer-range wireless broadband technology. The company stressed that it is taking a neutral stance on the next generation of wireless technologies, but the move raised eyebrows in the mobile phone industry.

Wimax, which can operate over many miles, is seen as a competitor to another next generation wireless technology, which is being developed by the mobile phone companies and builds on the existing 3G standard. LTE, or Long Term Evolution, is an mobile industry-led project designed to upgrade the existing 3G service. The LTE group is supposed to come up with recommendations on a new standard next month.

Earlier this year Vodafone's chief executive Arun Sarin warned that the process of getting a new wireless standard was taking too long. "As an industry it takes us a long time to get things done - we need to move faster or others will eat our lunch," he said.

Meanwhile The European Commission is opening up the wireless technology market by discarding out-dated rules limiting the areas of available radio spectrum. Next-generation wireless technologies such as BlackBerrys and smartphones work best over low frequencies that, until now, were reserved for GSM mobile phones. According to a statement last week, the Commission will allow new services to co-exist alongside GSM. The aim is to establish a more flexible, market-driven approach to spectrum management, says European Union telecoms commissioner Viviane Reding.

Vodafone plays the WiMAX card

Vodafone announced that it is to become a member of the WiMAX Forum, the organisation which tests and certifies interoperability for products based on the WiMAX standards. Vodafone sees the move as a means of taking a more technology-neutral approach to the future development of its business, by placing WiMAX on a strategic par with 3G LTE for a potential role in the next generation of mobile technology. Although mobile WiMAX is less mature than LTE at present, Vodafone believes it may have an important role to play for some of its national operating companies. Vodafone therefore wants to understand WiMAX better, and to play an active role in developing end-to-end specifications for possible future deployment.

WiMAX standard is often compared to Wi-Fi, though the comparison is unfair as WiMAX isn't based on a 20-year-old wired standard but was designed for wireless use (at least, the bits not borrowed from DOCSIS were). WiMAX offers greater speed and range than Wi-Fi, but most importantly it offers quality of service guarantees that make VoIP and streaming applications easier to manage.

"Our membership of the WiMAX Forum will complement our existing memberships of other key industry bodies such as the GSMA, 3GPP, and the Next Generation Mobile Network initiative," Vodafone global chief technology officer Steve Pusey said.

WiMAX has been heavily pushed by Intel, which intends to build it into laptop chipsets, encouraging rapid adoption of a technology in which it owns key intellectual property.

According to Ovum analysis:

Although a slightly crude generalisation, it's basically accurate to see the WiMAX Forum as the wireless Internet camp; the 3GPP as the wireless telecoms camp. There was a time when those two camps represented philosophies which were mutually exclusive and frequently antagonistic. These days, it makes less sense to see the world in those terms, because convergence between telecoms and the Internet - though far from complete - is now well under way. But at this early phase of the transition to convergence, it's not yet clear whether the predominant technologies and business models will eventually be those of telecoms, or those of the Internet. It's sensible, therefore, to remain interested in (and influential over) both possible outcomes, so long as they both remain possible.

Seen in that context, it seems perfectly natural that a large mobile operator would decide to join the WiMAX Forum. In Vodafone's case, the move is especially logical because of its increasing presence in emerging markets. The prospects for WiMAX to play an important role in the future development of mobile are better in those parts of the world where large numbers of people do not yet have access to telecoms or the Internet. If alternative models are going to take root, it's most likely to happen in areas with less legacy. On the other hand, the telecoms model will predominate for the forseeable future in more mature markets. Vodafone clearly needs to be involved in the development of both types of model, since its business encompasses both types of market.

It says something about the way mobile has changed since the turn of the century, that joining the WiMAX Forum just seems like an obviously sensible thing for Vodafone
to do.

Which Mobile TV technology to go for?

There is aa lot of confusion regarding which mobile TV technology to go for. An article in Telecoms Online gives an idea regarding which way the Chinese market is going for mobile TV.



A recent survey shows more than 40 percent of cell phone users in China like the idea of watching TV on handsets. Some pundits even predict the number of mobile TV users in China will jump to nearly 60 million in 2008, and revenue from handset sales and programming will generate 1.3 billion yuan (US$170m).

The road to mobile TV, however, most likely will be bumpy. Current trials have found several vulnerabilities, such as handset display hang-up when video content is loaded, short battery life and overheating, that must be fixed.

What’s really hindering mobile TV development in China (and, arguably, in other geographical regions), however, is lack of agreement on one standard. In June, a government agency overseeing the mobile TV industry reaffirmed CMMB (China Mobile Multimedia Broadcasting) as the official standard for 3G video service. The reason: CMMB is homegrown and completely free of foreign IPRs.

The State Administration of Radio, Film and TV developed CMMB last October, but a tug-of-war over the standard has undermined SARFT’s efforts to implement it this year. Despite a slow start, SARFT has obtained 25MHz in bandwidth on 2.5GHz for CMMB service and plans to build networks for the Olympics in six cities, including Beijing, Shanghai and Qingdao.

The other contenders CMMB must fight are DVB-H (Europe), Media-FLO (United States), T-DMB (Korea), DMB-TH (a digital TV spec modified for handheld developed by Tsinghua University), T-MMB (Nufrontsoft, which is aligned with MII, the Chinese telecom regulatory body) and CMB (Huawei).

For now, CMMB appears to be most appealing because of SARFT backing. SARFT’s control of programming and distribution in China gives CMMB a huge regulatory and cost advantage over rival mobile TV standards.
Recognizing that CMMB has clout in China, a large industry alliance of 120 companies backs the standard, including heavyweights such as Nokia, Motorola and Sony Ericsson, and Chinese firms like Lenovo, Huawei and ZTE.

One of the main benefits of CMMB, according to SARFT, is that it does not charge royalties for two years, saving an estimated 1 billion yuan (US$130m) in foreign IPR payments. SARFT hopes the savings will encourage handset manufacturers to cooperate in perfecting the standard and expediting proliferation.

There are other concerns. Some Chinese standards are not really independent but a hodgepodge of foreign versions. Reports say T-MMB, developed by Nufrontsoft, incorporates certain core DAB patents like DMB that will be in effect until 2013. Critics say if Chinese handset makers adopt T-MMB they will have to dole out hefty royalties–about US$6 per set or up to US$120m to US$300m per year.

CMMB and T-MMB use different approaches to video transmission and delivery. T-MMB uses a streaming overlay on top of mobile infrastructure, so that it shares the total bandwidth and download speed for the service, like the current video service. CMMB relies on a tuner installed in the handset to receive video signals over the air.

The T-MMB advocates say adding a tuner will compromise other features affecting handset and overall performance, while the CMMB supporters predict T-MMB will be dead on arrival because video traffic will crash the network and cost will skyrocket.

The debate over mobile TV standards is not just about patriotism and technology. SARFT has jurisdiction over broadcasting via various media outlets, including handheld devices, while T-MMB is a brainchild of MII which, by default, only provides a transmission conduit to end users but not content and distribution.

The problem is that both sides see mobile TV as a golden opportunity but want to run the market on their own terms. At this time, the central government sees it as a market issue and is reluctant to provide guidelines, so tussle over mobile TV probably will go on for some time before technical issues are straightened out.

UMA is not Dead

I did not hear about UMA for long time and i was starting to think that this would be one of the dead technologies that never saw the light of the day. I was wrong. It was pointed out to me by a colleague that T-Mobile (U.S.) recently announced Hotspot @ home that will allow UMA access to the Mobile while within a WiFi coverage area.

Note: UMA or Unlicensed Mobile Access is no longer called UMA but by its new name GAN or Generic Access Network

T-Mobiles GAN service lets users make phone calls over their in-home WiFi networks or over T-Mobile's national cellular network, depending on whether the customer is inside a T-Mobile HotSpot or not. The big problem with UMA, though, is that users must use dual-mode phones. T-Mobile's HotSpot@Home plan currently costs $10 a month after the purchase of a dual-mode phone and WiFi router, if one isn't owned already.

AT&T (again U.S) is also planning a similar move but its going the FemtoCell Way. Industry sources have revealed that AT&T has filed a request for proposal (RFP) to suppliers that may be interested in participating in AT&T's in-home femtocell service, according to wireless trade publication Unstrung. Femtocells are access points that act as repeaters to strengthen cellular communication signals inside homes, offices, and underground areas like subways. T-Mobile is trying to accomplish a similar task with its HotSpot@Home service, which brings better call quality to subscribers through the use of WiFi routers.

Although AT&T's femtocells would likely require a broadband internet connection, femtocells don't use the WiFi routers that most people already have in their homes. Instead, users would need to buy a new plug-and-play unit that could cost in the area of $200. Companies like picoChip currently develop reference designs for units that could be used by AT&T or its suppliers.

Because femtocells do not use WiFi signals, they don't require dual-mode handsets, which opens up the market to customers that don't want to ditch their current phones just to get the benefits of a stronger in-home signal. Meanwhile, potential T-mobile HotSpot@Home customers can only choose between two phones (the Nokia 6086 and Samsung T409), which means existing customers have to ditch their current mobile phones for a dual-mode device. Blackberry 8820 will soon be available in U.S. which has support of UMA.

Meanwhile Kineto Wireless, the innovator and pioneer of UMA, recently joined femtoforum. In addition to the promotion of femtocell deployment, the forum is focused on addressing several key technical issues, including radio planning and control, provisioning and management, and device-to-core network connectivity. As the core network technology behind a growing number of large-scale, dual-mode handset deployments, the 3GPP UMA standard is now being recognized as the de-facto standard for device-to-core network connectivity in the femtocell market as well. Recently, Kineto initiated interoperability testing between femtocell access points and its industry leading UMA Network Controller (UNC), and has already completed testing with Ubiquisys, the number one femtocell access point vendor.

"The femtocell industry is starting to appreciate the three year head start
UMA has over proprietary approaches being proposed for device-to-core network connectivity," said Patrick Tao, Kineto's vice president of technology. "As the
technology behind successful l dual-mode handset services, such as unik from
FT/Orange and T-Mobile's Hotspot @Home, the 3GPP UMA standard has already identified and addressed the real-world deployment issues operators face in
bringing femtocells to market. These issues include security, device
authentication, access controls, handover, regulatory compliance, as well as
scalability to support millions of endpoints."

One thing to remember here is that not all mobiles supporting WiFi will support UMA. On the other hand all phones that support UMA will support WiFi.

Certified Wireless USB is finally here

Two manufacturers of laptop PCs and two designers of wireless hubs and adapters are the first companies to receive consumer product certifications from the Universal Serial Bus Implementers Forum (USB-IF). The Certified Wireless USB products are expected to be in stores for the back-to-school and holiday gift season.

Previously certified silicon from Alereon, Intel Corp., NEC Corp., Realtek Corp., and WiQuest Communications are integrated into the products, according to the USB-IF.


The two laptop companies are Dell Computer for its Inspiron 1720 notebook and Lenovo for its ThinkPad T61/T61p 15.4-inch Widescreen Notebook. Networking companies D-Link and IOGear each had a wireless hub and also an adapter certified. Certification of the Wireless USB protocol by the USB-IF assures the interoperability of devices from a variety of manufacturers.

Certified Wireless USB is based on the WiMedia Alliance's Ultra-WideBand (UWB) common radio platform, which is capable of PHY-layer data rates of 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters.

From an engineering perspective, the question of co-existence with other wireless technologies in the 3 GHz band has been a persistent question for Wireless USB.


Dell and Lenovo have announced the first notebooks with embedded Certified Wireless USB chips - the Dell Inspiron 1720 and Lenovo ThinkPad T61and T62p. The laptops connect wirelessly to USB peripherals hooked up to Certified Wireless USB hubs such as those released by D-Link and IOGear. They will carry a Certified Wireless USB logo. In the interim, until peripherals catch up with the technology, they will need to be plugged into a wireless USB hub. This will allow the Dell and Lenovo laptops to communicate with a peripheral device such as a conventional printer plugged into the hub.

2G is Dead, Long live 3G

3G services may soon be allowed on the radio spectrum currently being used for 2G communications, after the European Commission officially backed the scheme.

Two bands of spectrum — at 900MHz and 1800MHz respectively — were set aside in the 1980s for use by the emerging 2G/GSM mobile-phone market. However, since 3G/UMTS became a reality earlier this decade, many users have switched over to the new standard, which operates at the higher-frequency 2100MHz.

This development has reduced the demand for the lower frequencies, and some mobile operators have been arguing for some time that those spectrums should "refarmed" for 3G services. Those operators have pointed out that lower frequencies allow the signal to be transmitted over greater distances and have suggested that, because 3G infrastructure has been deployed mainly in urban areas where the maximum return on investment can be made, refarming would allow greater use of 3G "mobile internet" services in rural areas.

However, one issue remains unresolved in the refarming debate. O2 and Vodafone use 900MHz for their GSM services, while T-Mobile and Orange use 1800MHz. The smallest UK operator, 3, has no GSM spectrum at all. Because lower frequencies transmit further, the EC's proposals have the potential to give O2 and Vodafone the chance to have greater 3G coverage, at a lower cost, than their rivals. 3 stands to be the most disadvantaged network as it has no GSM spectrum to refarm.

Neither Orange, T-Mobile nor 3 had responded to a request for comment on the EC's proposals at the time of writing.

Even more space could become available for 3G services next year when Ofcom auctions off 192MHz of spectrum around the 2.6GHz frequency. However, that spectrum could also be used for alternative mobile broadband services, like mobile WiMax. Pending a formal green light from the European Commission, Reding's proposals on refarming should be in place by the end of this year.

BT Movio ... going ... going ... gone

UK national telecommunication company British Telecom (BT) has closed its mobile broadcast branch BT Movio. The delivery platform developed by BT Movio supports the only mobile broadcast TV service in the UK. The service is retailed by UK largest mobile virtual network operator (MVNO) Virgin Mobile. The operator declared that the service will carry on until the beginning of next year. BT has cancelled its contract with GCap Media which provided access to the Digital Audio Broadcast (DAB) spectrum. GCap mentioned that the cancellation will take effect on 9 June 2008. GCap subsidiary Digital One which is in charge of the spectrum is currently seeking other partners to replace BT Movio.

Virgin had released only one handset — the HTC-manufactured "Lobster phone" — which supported the technology, and sales of that device were poor. The Lobster phone was seen by critics as an unattractive handset and, being based on Windows Mobile, it was not ideally suited to the consumer sector.

However, the final straw for BT was the recent backing given by the European Commission to the mobile broadcast technology Digital Video Broadcasting — Handheld (DVB-H). BT Movio was based on the rival Digital Audio Broadcasting — IP (DAB-IP) standard, which reused digital radio spectrum to deliver a handful of TV channels and a range of digital radio stations. DVB-H promises more channels, but spectrum availability for that technology had looked uncertain until it became apparent last week that the European Commission would force member states to adopt the standard.

According to screendigest:

Unicast mobile TV (i.e. distributed through 3G networks) has been relatively successful in the UK with three major operators launching services with more than 25 TV channels on average. According to Screen Digest, they were almost 450,000 mobile TV subscribers at the end of 2006. While unicast mobile TV can offer a wide range of TV content, the infrastructure can only sustain a limited number of users. In order to support mass market adoption mobile broadcast TV networks must be deployed. BT Movio launched the broadcast mobile TV service with Virgin Mobile in September 2006. The service showed poor uptake during the first 3 months with less than 10,000 subscribers. Factors blamed for the poor uptake include a lack of content and poor handset availability. The upcoming UK auction for L-Band spectrum could have given BT Movio the opportunity to increase the capacity of the current platform and improve the channel line-up. However, the BT Movio platform requires IP compatibility from the broadcast network technology. DVB-H, DAB and MBMS support IP encapsulation. T-DMB, the preferred technology for the L-Band spectrum auction, does not support IP. Therefore, BT Movio was stuck with a platform which cannot draw enough attention from mobile operators, handset manufacturers and inevitably mobile subscribers.

The UK operator '3' is keen to big up its own mobile TV and video services in the wake of BT's announcement. 3 UK says its customers have:

• Downloaded more than a million reality TV clips in the last year.
• Downloaded over a million SeeMeTV clips every month, with £100,000 being made by budding directors in the process.
• Last summer watched World Cup TV on their mobiles nearly 4 million times.

Among the live streamed channels 3 offers are BBC1, BBC3 and ITV1, with access starting at 49p a day. Its also allows customers to access TV from their set-top's with a Slingbox app.

HSPA in Latin America

From a press release by 3G Americas:

In the past few weeks, operators Personal and Movistar in Argentina, Movistar in Mexico as well as Movistar and Ancel in Uruguay have all launched UMTS/HSDPA commercial service in their respective markets in Latin America. In addition to the operators listed above, in the past seven months, UMTS/HSDPA has been launched by AT&T in Puerto Rico and Entel PCS in Chile, making a total of seven operators that offer UMTS/HSDPA in Latin America and the Caribbean.

The number of operator deployments of HSDPA has increased by 200% in the last year, from 42 HSDPA networks to 130 commercial HSDPA networks today in 61 countries. Today, there are 177 total deployments of UMTS technology in 74 countries and nearly 300 commercial HSDPA devices available worldwide. Informa Telecoms & Media estimates that there will be 190 million UMTS or HSDPA customers worldwide by the end of 2007.

Latin America has become one of the worlds’ fastest-growing regions for GSM wireless service, as many operators have migrated their networks from other technologies (such as CDMA and TDMA) to the GSM evolution to take advantage of the tremendous scope and scale, as well as technology benefits, offered by EDGE, UMTS and HSDPA. There are an estimated 255 million GSM subscribers in Latin America and the Caribbean as of June 30, 2007, representing a 75% share of market. In addition, many operators in the region have deployed EDGE high speed wireless data services; in fact, there are 38 commercial EDGE networks in 21 countries today.

Erasmo Rojas, Director of Latin America and the Caribbean for 3G Americas commented, “EDGE delivers an excellent customer experience for wireless data, serving as a foundation for customer uptake of wireless data services and increasing revenues for all GSM operators. The next move is to UMTS/HSDPA mobile broadband. We expect many more launches of HSDPA in 2007 and 2008 throughout Latin America and the Caribbean.”

As GSM customers push for speed and applications to satisfy their demands for services such as web browsing, email, mobile payments, interactive gaming and video sharing, UMTS/HSDPA provides the solution with average downlink throughput data rates over 1 Mbps in favorable conditions and latency measuring at 70-100 milliseconds. +

Many more operators throughout Latin America and the Caribbean are planning their move to mobile broadband with HSDPA. Rojas continued, “However, some carriers need additional spectrum allocations before UMTS/HSDPA networks can be launched.”

Google jumps on the Femtocells Bandwagon

Ubiquisys recently announced that it has secured funding from Google for its ZoneGate Femtocell. This is an interesting move from the Internet Giant which has also been showing interest in Mobile Phones.

The Inquirer suggests that if Google is showing interest in Femtocells then they have become sexy.

Ubiquisys's Zonegate femtocell plugs into DSL and then provides access to WiFi, Ethernet, ordinary telephones and USB. But the most important thing is that it also acts as a local 3G base station. So Google has something in mind which can be done by providing Broadband in homes.

Dean Bubbly, writing in Seeking Alpha says that he is surprised by Google's move. He writes:

Yes, I know that Google's talking about pitching $4.6B for the US 700MHz spectrum... and yes, I know that there's a 700MHz standard for UMTS going through 3GPP at the moment. But I'd have thought that femtos at that sort of
frequency was fairly pointless, as the big attraction of 700MHz is that it's got great range and goes through walls easily.

The real advantage of 3G femtos, in my view, lies in 2100MHz 3G spectrum (i.e. most of the world today outside the US), and probably in the future in 2600MHz band. It's conceivable that Google might want to start bidding for those chunks of spectrum around the world, but I'm unconvinced that it's
going to follow the classic cellular path (i.e. 3GPP UMTS or LTE) rather than something more Internet-like.

There's an outside possibility that Google might, in fact, want to do something with WiMAX - but at present, Ubiquisys doesn't do WiMAX femtos, although chipset supplier PicoChip is certainly doing suitable silicon. Maybe that's what the investment's for . . .

What no one is talking about is, Is there some way of advertisement using Femtocells? I am sure if Google is going this way then there must be something on advertisement.

We will have to wait and see.
