Worlds Worst War

The annual D&AD award winners have been announced with a ‘Yellow Pencil’ going to an interesting campaign by Tokyo-based agency Hakuhodo for snack food client Tohato.

The World’s Worst War used two new spicy snack flavors as opposing forces and engaged players to invite friends, thereby increasing their own personal rank, to join forces of either the Habanero Evil Army or the dreaded Satan Jorquia… Yikes. Better to watch the video!

The simplest way to understand this is the self explanatory youtube video:

Tomi has interesting post on this here.

E-MBMS out of Rel-8, CBS in

E-MBMS is out of Release 8 and CBS (Cell Broadcast Service) is back in LTE. CBS as far as I am aware is not used much anywhere except Japan. CBS has been added specifically as now there is requirement for EWTS (Earthquake and Tsunami Warning System) .

Clever move from LTE camp regarding IPR costs

Finally, probably because of threat from WiMAX, LTE vendors have announced a mutual commitment to a framework for establishing predictable and more transparent maximum aggregate costs for licensing intellectual property rights (IPR) that relate to 3GPP Long Term Evolution and Service Architecture Evolution standards (LTE/SAE). The companies invite all interested parties to join this initiative which is intended to stimulate early adoption of mobile broadband technology across the communications and consumer electronic industries.

Alcatel-Lucent, Ericsson, NEC, NextWave Wireless, Nokia, Nokia Siemens Networks and Sony Ericsson are the initial signatories

The framework is based on the prevalent industry principle of fair, reasonable and non-discriminatory (FRAND) licensing terms for essential patents. This means that the companies agree, subject to reciprocity, to reasonable, maximum aggregate royalty rates based on the value added by the technology in the end product and to flexible licensing arrangements according to the licensors’ proportional share of all standard essential IPR for the relevant product category.

Femtocell - The new jargon

I was in the Wireless 08 event yesterday in London to hear more about Femtocells and there were some very interesting presentations. There are lots of new terms floating around and they are as follows:

• Super-Femtocell: Well this term is being used by IP Access to refer to their Picocell. I am not sure if this is the right way to refer them but they aare surely getting lot of attention. Super-Femto is another variant of this term and so is 'femtocell on steroids'
• Femto++: This term was used by Airvana to refer to enterprise femtocell. They also refered to it as eFemto.
• Cognitive Radio Femtocell: This was referred by Ubiquisys. I was really impressed with this one and will write a blog later on this one.

So listen all you spammers who buy up all the website names to sell at profit later. Now is your time, so read this blog carefully and off you go ;)

Dell to power laptops with HSPA

Ericsson has a press release saying that Dell will use its high-speed HSPA mobile broadband technology in next-generation laptops due in the second quarter of 2008. The modules will be built in to the Dell laptops, according to a press release by both companies. By June, Intel is expected to roll out its next-generation "Montevina" mobile chipset, which will be used as the foundation for the next generation of Centrino notebooks.

Although Montevina was expected to usher in the next-generation WiMAX technology, the apparent delays underlying Clearwire's WiMAX rollout may have pushed Dell to seek an alternative broadband choice.

According to a Dell spokeswoman, the choice to include Ericsson's HSPA technology was as much about compatibility as throughput. If a customer takes a 3G-enabled laptop with him or her to Europe, it might work, "but it's not a seamless transition," Dell's Anne Camden said. The HSPA technology is more uniform throughout the globe, she said.

But it's also true that Dell wanted a broadband solution now. "Mobile broadband delievers a broadband experience today, and that is what we need," Camden said. "We want to deliver a great broadband experience. We're certainly looking at WiMAX support in future products."
Dell is the second major PC vendor to sign on to use Ericsson's HSPA technology, after Lenovo.

According to Ericsson, both Dell's business customers and consumers will use the new modules. Interestingly, Ericsson built in a GPS component into the HSPA modules, meaning that location services will be also be built in.

Market projections indicate that in 2011, approximately 200 million notebooks will ship annually and Ericsson anticipates that 50 percent of those notebooks will feature a built-in HSPA mobile broadband module. Users will increasingly have the option to take their broadband connections with them, delivering on the promise of full service broadband, which is anytime, anywhere access from the screen or device of choice.

Meanwhile:

Winners of Sweden's 2.6GHz spectrum auction can now look to rapid deployment of advanced mobile networks, with Ericsson poised to deliver end-to-end HSPA and LTE technology. The auction is the first held in the world to license according to the harmonized band arrangement decision by the European Conference of Postal and Telecommunications Administrations (CEPT).

As a front runner in allocating the 2.6GHz frequency band, the regulator Swedish Post and Telecom Agency has adopted a harmonized spectrum allocation as defined by CEPT. The allocation will facilitate economies of scale for operators and secure the availability of standardized terminals, allowing roaming between countries for users. Auctions of the 2.6GHz band in Austria, Netherlands, Italy and the UK are scheduled for 2008.
LTE and HSPA, the preferred technologies for the 2.6GHz band, enable a superior, mass-market user experience, enhancing demanding applications such as mobile video, blogging, advanced games, rich multimedia telephony and professional services.

Ericsson's solutions help operators leverage their network investments by providing optimal voice communication and mobile broadband services. Ericsson employs scalable architecture and allows seamless network expansion, providing an efficient migration path to broadband, regardless of the legacy technology in place.

Ericsson's offerings for the 2.6GHz band are based on its multi-standard RBS 3000 and RBS 6000 series. These energy efficient base stations support WCDMA/HSPA/LTE and GSM/EDGE/WCDMA/HSPA/LTE respectively. Ericsson's RBS suite offers the smallest base stations on the market and facilitates low-cost migration and easy network integration. HSPA is already commercially deployed in more than 185 networks in 80 countries, with more than 600 devices launched.

Introduction of Hierarchical cells by the networks

This one is from Dean Bubley's Disruptive Wireless Blog. Now I was under the impression that the network operators have already deployed multiple frequencies and have a hierarchical arrangement as in the diagram above. This may not be exactly true as according to Dean's post it seems that only now the operators are looking at this option.

Surely the people already involved in field testing can tell us if they are seeing Inter-frequency measurements and if they are wouldnt this indicate multiple frequencies?

My thinking was that when the operators rolled out HSPA they kept the HSPA part on one frequency and they let the existing 3G on the original frequency. This helped them keep everything smooth without worrying too much about the code tree management.

Now Dean has something on Femtocell and since I have posted on this topic recently, I am quite interested in his views:

Austria is a bit of an outlier in adoption of HSPA, with data traffic apparently now 20x outweighing voice on the network, but it's an interesting indicator of what's coming down the line. HSPA networks are now having to deploy an extra set of transmitters on the base stations. For those readers who don't follow this area, 3G UMTS networks (including HSPA), use 5MHz spectrum slices. Most operators have allocations of 10, 15, 20MHz or more, but typically haven't been using all of their theoretical capacity thus far. if you assume that most countries will take two years from launching flatrate dongle plans, rather than one year, to fill up the first 5MHz, it's an early indicator of demand ramp-up for spectrum (and capacity) over the next few years. This is especially true as end users get used to higher-speed HSPA, as well as increases in the total number of users. Add in some growth in data traffic from phones with decent browsers or video clients, and it starts to look as if the 2.1GHz 3G band is going to fill up very quickly. This has a number of implications:

• Firstly, there's a short term business case for femtocells - if they can work out cheaper than adding a second or third 5MHz carrier on the macro network. On the flipside, some of the calculations I've seen have suggested that femtos substitute for new extra base stations rather than adding extra kit to existing ones. I'm not sure what the comparative costs are, but I guess that bring up a 2nd carrier must be a lot less. [Not much discussion from Ericsson about femtos for 3G macro-offload (or indeed at all), to be honest. My take is that as well as potentially impacting its overall integrated base station/transmission business model and bringing in new competitors, I get the distinct impression that the Big E is a little skeptical about some of the femto hype on a fundamental basis.]
• Secondly, it means that operators will need to get extra spectrum if they're serious about continuing to drive mobile broadband. 2.6GHz is the obvious big chunk, but refarming 900 and 1800MHz GSM starts to take on more urgency ( as well as expediency for coverage reasons).
• Lastly, it means that operators are going to be faced with some unpalatable choices in terms of capex for HSPA - having to choose between fulfilling the need for extra 5MHz carriers in high-use areas, versus continuing 3G build out in areas with no coverage at all. I suspect that this is going to drive a lot more emphasis on EDGE - and EDGE Evolved, as an interim coverage solution in marginal areas, as it wring more life out of existing 2G base stations. Interestingly, the GSA has been talking up EDGE today as well.

I am going to try and digup some information on UK operators on the frequency usage as this may probably help understand about the situation better.

Qualcomm to back MediaFLO at the expense of MBMS

Just couple of days back I was complaining about everyone abandoning MBMS but now I can see why Qualcomm is suddenly uninterested in MBMS:

U.S. mobile technology company Qualcomm Inc. (QCOM) said Friday that it acquired an L-band radio spectrum licence for GBP8.3 million that will enable it to bring new mobile TV and wireless services to the U.K.

Qualcomm U.K. Spectrum Ltd bought the licence to use 40 Megahertz of the 1452 MHz to 1492 MHz band in an auction by communications regulator Ofcom.

The licence is suitable for offering mobile television, wireless broadband and satellite radio, Ofcom said.

The L-Band spectrum license acquired by Qualcomm covers the entire United Kingdom and is technology neutral, thereby enabling Qualcomm to use the spectrum for innovative technologies, depending on its assessment of market needs in the United Kingdom.

The L-band, on which any technology or service can be used, will contend with two main rivals, DVB-H, backed by Nokia, the handset maker, and by Viviane Reding, the European Telecoms Commissioner, who wants to make it the European standard, and TDTV, which is being tested by Orange and T-Mobile in the UK. All three technologies would require special handsets able to pick up a broadcast signal.

Mobile companies including Vodafone and 3 already offer mobile television in Britain, but take-up has been poor.

Qualcomm said that it does not intend to run a mobile TV broadcasting network as an operator, as it has done in the United States, but is looking for partners to launch its mobile television technology, MediaFLO.

Andrew Gilbert, head of Qualcomm's European operations, said: “We will not attempt to become an operator, but if service providers want to partner with us ... we are open to talking to folk.” Mr Gilbert added that Qualcomm would use the spectrum to bring a variety of wireless technologies to the UK market but that it had no timetable for launches in mind.

With industry heavyweights supporting DVB-H and TDTV, analysts see this as Qualcomm's last chance to bring MediaFLO to the UK and European markets. Will Harris, of Enders Analysis, said: “One potential outcome from this is that two competing mobile TV services could be launched. While it is too early to say which technology will win at this stage, those that fail to get support from the mobile operators will lose.”

O2, the mobile network provider, was initially interested in the L-band auction, but pulled out without bidding. Failed bidders include WorldSpace, the satellite radio group, and The Joint Radio Company, which runs spectrum for the UK energy industry.

The next competition, to run later this year, is even more significant. It has a price tag that could run into the tens of millions because it is for a frequency that supports WiMax, a high-speed network technology similar to a common WiFi home wireless system, but with a more robust signal and a range of a kilometre or more.

Although WiMax is not new it has had little success so far. But interest is hotting up. In the US last week, Sprint Nextel announced a $14.5bn (£7.4bn) joint venture with Clearwire to build a network servicing as many as 140 million people by the end of 2010. And Google is pumping another $500m into the scheme.

At the moment, the UK market is small. Freedom4 and UK Broadband, a subsidiary of PCCW, are the only providers with a national licence, and only limited services are available. But developments on the other side of the Atlantic are fuelling interest, and some big players are lining up for the relevant spectrum auction. Ian Livingston, who takes over aschief executive at BT in two weeks' time, has said thecompany is interested, and Vodafone has trials running in Malta.

Freedom4 is also already in talks with potential investors about the £100m infrastructure funding it estimates it will need from 2009-11. "We are talkingto our partners and the banks," Mike Read, chief executive of Freedom4, said. "Following the deals in the US, there is moreinterest in what we are doing over here."

Ian Keene, a senior analyst at Gartner, said: "There is abusiness case for WiMax in the UK, but most likely it will becity-centric and focused on business, rather than nationalcoverage competing with mobile networks."

The biggest auction of all will be next year's bidding for the "digital dividend" – the wide bands of frequency freed up when the analogue television signal is switched off in 2012. The debate about who should get what is already well under way. Broadcasters claim a substantial portion for high-definition TV, mobile operators want it for next-generation cellular services such as video, and internet service providers say it iscrucial for the broadbandinfrastructure.

LTE latest news and status

In the past year or so there has been lot of talks about the next generation wireless technology and the significance toward adopting these technologies. One of such technology which is very much a popular discussion these days is LTE. Over the last one year LTE air interface and its architecture has become clearer. Significant developments have been made in finalising the LTE architecture and OFDMA and SC-FDMA as radio access technology. LTE as a technology has a come long way in terms of finalising the air interface and other standards. 3GPP1 and 3GPP2 is working hard to get the latest specification out so that telecomms companies start drafting their plans in order to implement the technology.

Giants like Nokia, NTT DoCOMO, Ericsson, Vodafone and others have already started their research and development on LTE thus giving enough indication that LTE is going to be the technology adopted by most as a next generation wireless technology.

Long-term evolution (LTE) promises to make everything from mobile-video sharing to music downloads speedier, but it may not show a visible boost in sales for the network equipment industry any time soon, as the first networks are not expected for two years and many operators will wait longer until the technology matures.

Verizon Wireless, the number-two US mobile service, has decided to build out an LTE network, while China Mobile, the world's biggest mobile provider, said earlier this year it would test LTE.
Alcatel-Lucent and Japan's NEC signed a joint-venture deal to pool their development and marketing of the technology. Even Qualcomm has promised chips for LTE, a competitor to its own Ultra Mobile Broadband technology.

Ericsson recently unveiled a glimpse of what the future of mobile Internet will bring, announcing its new M700 mobile platform, capable of LTE (Long Term Evolution) data transfer speeds. Ericsson says this is "the world's first commercially available LTE-capable platform", and we have no choice than to believe it, especially since the Swedish company sustains the platform will bring data transfer speeds of up to 50Mbps (when uploading) and up to 100Mbps (when downloading). Sure, these speeds are not comparable with the ones achieved by NTT DoCoMo's Super 3G network (250Mbps), but they are obviously better than what the current 3G networks can offer. Moreover, these new speeds can surpass, in some cases, the data rates achieved by fixed lines, allowing the development of real-time mobile services, including video streaming and on-line gaming.

Nokia Siemens has already achieved speeds up to 173 Mbps with LTE in a trial of the LTE wireless data network. The field trial was conducted in an urban environment and was meant to test the performance of LTE in "real" environments. This is in contrast to a demonstration of the technology a year ago that achieved speeds up to 160 Mbps.

LTE technology is competing with WiMAX to deliver high speed mobile networks, and both have high profile supporters worldwide. The LTE project was designed to evolve the current 3G technology used today, and Erissson’s prototype together with the Nokia Siemens test shows clearly which camp the companies are in.

There are others who like Ericsson putting a lot of efforts in LTE and thus making it clearer that they prefer LTE as compared to WiMax.

During its first quarter conference call with investors, Alltel announced that it was committed to evolving its network to LTE over the next five years. The move makes Alltel the second biggest CDMA carrier in the U.S., after Verizon Wireless, to commit to the LTE standard, even though LTE was originally on the GSM evolution path. "We do currently plan to move towards LTE in the three-to-five year timeframe vs. WiMAX, but we're still early in that," President and CEO Scott Ford said during the call.

Huawei Technologies ("Huawei"), a leader in providing next generation telecommunications network solutions for operators around the world, has already announced that it has joined the Long Term Evolution / System Architecture Evolution (LTE / SAE) Trial Initiative ( LSTI ) and will hold the infrastructure vendor seat of the 2008 LTE/SAE Trial Initiative Steering Board.
The LTE/SAE Trial Initiative brings together major telecom vendors and operators, committed to driving the development of next-generation, high-performance, mobile broadband networks and 3rd Generation Partnership Project (3GPP) LTE and SAE technologies. Huawei's active in LSTI reflects commitment to contributing significantly to the development of HSPA, HSPA+ and LTE technologies, as a leading global telecommunication solutions supplier.

Looking at the trends and developments in LTE, vendors has already started lashing out on
LTE licensing.

Rohde and Schwarz is also not lagging behind in it’s efforts to make sure that its system simulators are available for the vendors when they are ready to test their first LTE device. By including the latest revisions of the 3GPP LTE standard in the firmware for its signal generators, Rohde and Schwarz is already offering highly flexible testing for LTE equipment. Rohde and Schwarz has added channel coding and MIMO precoding for up to four transmit antennas to its industry-leading signal generators for LTE (uplink and downlink) Whether mobile equipment manufacturers are looking for an all-in-one solution for 2x2 MIMO signals and real-time fading or simply need standard-compliant RF or baseband signals, Rohde and Schwarz offers the answer.

MBMS - R.I.P.

Even though slow progress on MBMS (Multimedia Broadcast Multicast Service) has been going on for some time, just found out through sources that the two biggest promoters of this technology have put it on backburner. The reason they cite is the lack of interest from operators. They do not have a burning need for Mobile TV technologies as they are still able to cope with the demand by streaming point to point connections.

Somebody told me on condition of anonymity that the big operators in UK are at a breaking point but the things are still surviving because in the peak hours (9am to 5pm) there is not much demand for Mobile TV and the voice occupies the complete bandwidth. Whereas after 7pm and before 7am there is an even distribution of data and voice services. In the buffer zone (7am to 9am and 5pm to 7pm) data is being given low priority and many data calls dont work. This would cause decent revenue loss except that most of the people on data plans have a flat rate package so it does not bother the operators.

This is despite the announcement last month about Huawei and Qualcomm successfully completing their IOT with Telecom Italia. Orange and T-Mobile has been trialling MBMS based on TDtv technology but lets accept the fact that it is TDD-MBMS rather than the FDD-MBMS which other manufacturers like Qualcomm, Nokia and Ericsson are (were) actively working on.

I read this blog some days back and it emphasised what I have been saying for years now that there will always be multiple technologies floating around. MBMS could be a starting point for Mobile TV but as the demand grows it will have to be supplimented by other specialised technologies like DVB-H, DMB-T, MediaFLO, etc, etc.

For the time being, rest in peace MBMS.
