LTE functionality frozen as part of Release 8

According to 3GPP website: 3GPP has approved the functional freeze of LTE as part of Release 8.

There is significant commitment from operators to deploy this technology, and this landmark achievement will allow them to realize their early deployment plans.

But the 3GPP decided to give more time to the work on SAE -– a.k.a. evolved packet core (EPC) –- because the specs weren't complete enough. The standards body has drawn up a list of "exceptions" that will have until March 2009 to be finalized in order to be included in Release 8.

"There are a number of pieces of work which we thought should be included but weren't quite ready," says Scrase. "[There are] quite a number of parts for SAE, the work [on which] still lags behind LTE work. We have a high level of confidence that the items will be completed by March, otherwise we wouldn't have included them on the list."

Scrase says that it is common to extend deadlines in this way and that the 3GPP allowed a similar extension for Release 7.

The decisions about LTE and SAE took place at a 3GPP meeting in Athens last week, where the group definitively agreed on what is contained in Release 8 and what's not, according to Scrase. The group also agreed on what should be included in Release 9, which is scheduled to be frozen in December 2009.

And there is more to Release 8 than LTE and SAE. For example, some of the specifications for femtocells -- or "Home Node B" in 3GPP terminology -- are included in the release.

It's Aeroflex turn now to launch it's LTE product

As the competition is spicing up for the LTE race, companies have now started to launch their LTE products.

Continuing with the trends and keep the competition alive it’s now Aeroflex which launched the TM500 TD-LTE test mobile.

This latest LTE test mobile is designed to support Time Division Duplex for 3G LTE (TD-LTE) and will definitely compliment Aeroflex's TM500 LTE-FDD for 3G LTE Frequency Division Duplex quite well.
Ever since China mobile announced its plans for TD-LTE there was immense pressure on the equipment vendors to meet the demands. TM500 TD-LTE test mobile is designed to enable infrastructure equipment vendor’s match that demanding timescales for TD-LTE trials in China.
The TM500 TD-LTE's extensive Layer 1, Layer 2 and higher layer test features make it an indispensable testing peer that provides complete visibility even into the lowest layers of the radio modem by generating the detailed diagnostic data needed for engineers to verify the required functionality and optimize network operation and performance.
Following are further characteristics of TM500 TD-LTE:

• Support MIMO,
• Handover testing is simple and supported well,
• The test mobile can support 20MHz channel bandwidths and downlink data rates of upto 150Mbit/

All the above characteristics if the test mobile will enable comprehensive development and test support of base station and network infrastructure for the next generation of Chinese mobile technology.

The TM500 TD-LTE can co-exist in the same unit as the TM500 LTE-FDD protecting investment and maximizing test flexibility for engineers working on both standards.
Aeroflex will provide full in-country support for the TM500 TD-LTE so that technical questions and integration issues can be dealt with in Chinese and Aeroflex engineers can get on-site quickly, if needed, without having to fly in from Europe or the USA.

The TM500 TD-LTE will be available for customer shipment in late 2008.
It will be available both as a standalone unit and as an upgrade to existing TM500 LTE-FDD systems.

Satellite based Mobile Internet of the future

Background: The current US military satellite communications network represents decades-old technology. To meet the heightened demands of national security in the coming years, newer and more powerful systems are being developed.

Advances in information technology are fundamentally changing the way military conflicts are resolved. The ability to transmit detailed information quickly and reliably to and from all parts of the globe will help streamline military command and control and ensure information superiority, enabling faster deployment of highly mobile forces capable of adapting quickly to changing conditions in the field. Satellite communications play a pivotal role in providing the interoperable, robust, "network-centric" communications needed for future operations.

Military satellite communications (or milsatcom) systems are typically categorized as wideband, protected, or narrowband. Wideband systems emphasize high capacity. Protected systems stress antijam features, covertness, and nuclear survivability. Narrowband systems emphasize support to users who need voice or low-data-rate communications and who also may be mobile or otherwise disadvantaged (because of limited terminal capability, antenna size, environment, etc.).

For wideband communication needs, the Wideband Gapfiller Satellite program and the Advanced Wideband System will augment and eventually replace the Defense Satellite Communications System (DSCS). These satellites will transmit several gigabits of data per second—up to ten times the data flow of the satellites being replaced. Protected communications will be addressed by a global extremely high frequency (EHF) system, composed of the Advanced Extremely High Frequency System and Advanced Polar System. These systems are expected to provide about ten times the capacity of current protected satellites (the Milstar satellites). Narrowband needs are supported by the UFO (Ultrahigh-frequency Follow-On) constellation, which will be replaced by a component of the Advanced Narrowband System

Lockheed Martin Space Systems, Hughes Space and Communications and TRW have formed a National Team to build the Department of Defense's (DOD) next generation of highly secure communication satellites known as the Advanced Extremely High Frequency (AEHF) system.

The Advanced EHF programme provides the follow-on capability to the Milstar satellite programme. It provides the basis for the next generation military communications satellite system, for survivable, jam-resistant, worldwide, secure, communications for the strategic and tactical warfighter. The system replenishes the Milstar constellation in the EHF band.

Each of these Advanced EHF satellites employs more than 50 communications channels via multiple, simultaneous downlinks. Launch of the first AEHF satellite is planned for April 2008 with the second AEHF satellite scheduled for launch in April 2009.

The fully operational Advanced EHF constellation will consist of four crosslinked satellites, providing coverage of the Earth from 65° north latitude to 65° south. These satellites will provide more data throughput capability and coverage flexibility to regional and global military operations than ever before. The fifth satellite built could be used as a spare or launched to provide additional capability to the envisioned constellation.

Current Status: After being plagued with project overruns and a scaling back of the final system, the US military's next generation satellite communications network is another step closer to reality, with completion of the payload module for the third and final Advanced Extremely High Frequency (EHF) satellite.

Although the EHF band is a relatively lightly used part of the electromagnetic spectrum (30-300 GHz), it is for good reason. Atmospheric attenuation is the biggest problem faced in this band, especially around 60 GHz, however the frequencies are viable for short distance terrestrial based communication links, such as microwave Internet and telecommunication links (which already operate in this band). Millimetre wave radar, probably best known as the radar that can see through your clothes but not your skin, also operates in this band.

Designed to avoid problematic frequencies that are more susceptible to attenuation, but accepting increased overall atmospheric attenuation, are an increasing number of military and civil satellite systems that are using this band for uplink and downlink, as well as inter-satellite communication. Inter-satellite communication is really where EHF equipment shines (no atmosphere, small antennas, high data rates).

Civilian systems are currently around the Ku band (Intelsat), providing data rates of up to 2-4 Mbps (14 GHz uplink, 12 GHz downlink) however these rates have still to trickle into everyday user's hands for remote and mobile Internet access. It is more common that an aggregator will access this link/rate and use that to then portion out local Internet access. Systems such as this are in use for remote Australian territories like Cocos and Christmas Islands, and formed the backbone of Boeing's stillborn Connexion in-flight Internet access. High ongoing access costs (basically a share of the overall cost of the satellite) and limited access slots help keep the technology away from everyday use at this time. Militaries and governments around the globe also lease access on these circuits when they need the added capability, with Intelsat and Inmarsat systems being used in the first Gulf War.

Advanced EHF is designed to provide 24 hour coverage from 65 North, to 65 South across the K and Ka sub bands, and when combined with the prototyped Extended Data Rate (XDR) terminals and systems, will offer up to 8.2 Mbps data rates for around 4,000 terminals in concurrent use per satellite footprint (whether that scales to 12,000 systems in concurrent use globally isn't clear from source material).

Within the tri-satellite constellation, inter-satellite EHF links will allow terminals on opposite sides of the globe to communicate in near real-time without the use of a terrestrial link. Combined with smaller, directional antennas and the various options for anti-jamming technology, it represents a significant military capability for the US.

Already plans are being drawn up for the Transformational Satellite Communications System (T-Sat) which will replace Advanced EHF starting sometime in 2013, however it is already facing funding troubles. This could be problematic, with Advanced EHF still struggling to reach capability and the final launch not scheduled until April 2010. Dropping the fourth satellite of the Advanced EHF constellation has been planned to give the USAF time to implement T-Sat more rapidly.

If GPS and remote imaging (think Google Earth) have proven anything, it is that technology initially developed for military purposes, and extremely expensive for initial civil use, will eventually reach the point where it forms part of our daily lives without us ever being conscious of the massive investment to get to that point.

Metro Femtos another option for LTE.

Around six months back, Unstrung article mentioned that Vodafone dreams of Metro Femto. Now Doug Pulley of picoChip s all set to champion this concept. In the recently concluded LTE World Summit, he said "The macrocell is dead. It's a fallacy to think you can reuse existing cell sites to get LTE services. That whole premise is broken."

Both China Mobile and T-Mobile have said they plan to use existing 3G cell sites for their LTE networks. But Pulley contends a traditional macrocell deployment won't work because of the basic laws of physics.

Here's the deal: "User throughput rolls off the further you get from the base station," says Pulley. "[With] increased throughput, the signal becomes more sensitive to noise and interference. The further it has to travel, the weaker it gets."

So that means LTE cell sites need to be small and a have smaller radii than traditional macro sites to get the full data throughputs that LTE can offer, which will be up to three to four times higher than 3G HSDPA release 6, according to Adrian Scrase, CTO at the 3rd Generation Partnership Project (3GPP) .

"You've got to have new sites, and the capex implications of that are potentially horrible," says Pulley.

So future LTE femtos have to be cheap. PicoChip is developing a system-on-chip (SoC), code-named Feynman, that will enable a dualmode HSPA/LTE residential femtocell with a bill of materials of $70 in 2011. A lamp-post mounted, dualmode HSPA/LTE version of the femtocell will have a bill of materials of about $170.

"This is orders of magnitude cheaper than doing it any other way," says Pulley.

For equipment suppliers, though, the concept of small, cheap base stations, especially those that might supplant current base station models, is causing some tension, according to Pulley.

T-Mobile is keen on LTE femtocells. "Femtocells [will be] an important measure to supplement LTE for indoor coverage and capacity scenarios," says Frank Meywerk, senior vice president for radio networks at T-Mobile.
And China Mobile suggested that operators outside China could use the TD-LTE (Time Division LTE) version of LTE for capacity-enhancing femtocell deployments. That's an option for many European operators that, as part of their spectrum allocations for 3G UMTS services, have been awarded 5 MHz of time-division duplex (TDD) spectrum, along with their primary allocation of frequency-division duplex (FDD) spectrum.

TD-LTE would be a particularly useful choice for operators looking to maximize coverage in dense urban areas, as such deployments would "not interfere with FDD spectrum," according to Bill Huang, general manager at the China Mobile Research Institute. "I've heard that without having fixed spectrum allocated to femtos, it's not possible to deploy femtocells" because of interference issues.

Canada's Telus presented findings that femtocells do indeed have better performance in metro deployments.

"We're all here today to determine if there is a performance difference with going with very small cells," said Sam Luu, associate director of technology planning and strategy at Telus. "There is a significant performance difference at the edge and at the site."

But Luu cautioned that metro femtos are, for now, still only an interesting idea. "You can talk about technical better performance," he says. "But it still requires the R&D to get it off the ground. We're still in the early stages of evaluating the technology."

I have mentioned here and here that Femtocells can be considered as starting point for LTE rollout. Thinking about all the posts, it may be a better that an enhanced version of Femtocell or Femto++ is used. By this i mean that traditionally HSPA/LTE Femtocells are to allow max. 4 calls (more correct would be 4 radio links because the users could be in multi-call with CS and PS connection ... I know there is no CS for LTE but I am talking about HSPA) simultaneously and the Femto++ would allow 16 calls simultaneously.

In fact Huawei has a 16 channel Femtocell that is being trialled but not everyone is happy to refer to it as a Femtocell. A better term suggested is Picocell or my personal view is that depending on the power output, it could be classed as Femto++ or Picocell.

Operators can also reduce the cost of rolling out Metro Femtos by encouraging users to keep the access open on their Femtocells open and giving them a reward for every originating and terminating call made on their Femto.

LG causes a stir with the first LTE handset modem chip

LG recently announced that it has independently developed the first handset (user equipment) modem chip based on 3GPP Long Term Evolution (LTE) technology standards. The modem chip can theoretically support wireless download speeds of 100Mbps (megabits per second) and upload speeds of 50Mbps. This represents a significant step toward creating a market-ready 4G phone.

LG demonstrated the chip at its Mobile Communication Technology Research Lab in Anyang, Korea, achieving wireless download speeds of 60 Mbps and upload speeds of 20 Mbps. The fastest phones currently on the market use HSDPA technology and download at a maximum speed of 7.6 Mbps.

For the past three years, LG have been pursuing 3GPP LTE standardization, working to develop and test commercially viable LTE technology with approximately 250 of R&D staffs. The result is a 13 by 13 mm modem chip, perfectly sized for the next generation of slim-yet-powerful handsets. For its demonstration today, LG used a test terminal running Windows Mobile to play back high quality, on-demand video. In addition to this handset modem, LG is also developing the first preliminary LTE-based data card, which can replace the wireless cards currently used in computers.

“Now that LG has developed and tested the first 4G handset modem, a commercially viable LTE handset is on the horizon,” said Dr. Woo Hyun Paik, CTO of LG Electronics. “This latest breakthrough gives us a strong technology advantage that we will use to bolster our industry leadership.”

Dr. Paik added, "Our successful development of this LTE handset modem signals the start of the 4G mobile communications market. LG will continue to advance this technology and develop further technologies to maintain global leadership.”

Mobile phone carriers have now built LTE test networks and are currently working on early stage handsets. The first LTE mobile phones will likely reach the market in 2010.

If you remember, LG was one of the partners with T-Mobile and Nortel when they tested LTE some months back.

Anyway, LG also caused a stir with this announcement because it boasted of having 300 patents related to the technology.

The report, in Korea Times, caused ripples of nervousness because LG is not a participant in the patent pool that several large vendors formed last spring for LTE. The aim of this group is to create a cross-licensing framework, and sign up sufficient numbers of IPR holders, that it will achieve “fair and non-discriminatory pricing” amounting to a single digit percentage of the cost of a handset, and single digit dollars for a laptop, for all associated intellectual property, commented Arstechnica.

Patent pools are gaining in popularity as new standards emerge with ever larger numbers of patents involved, but with rising pressures to be cost effective. The WiMAX community created the Open Patent Alliance earlier this year, and this week, the IEEE standards body struck a two-year deal with Via Licensing, one of the most prominent patent pool administrators. This agreement will create one or more patent pools for key IEEE communications standards, including Wi-Fi. The standards group believes this will help drive its specifications into the market more quickly because vendors will have greater confidence that IPR licensing will be fair and patents declared upfront before standards find their way into commercial products.

There were some interesting discussions on IPR framework in the LTE World Summit that i will hopefully blog soon about.

Forward texts to your email account

In the past few years text messaging has really grown especially with the young people like me although it’s a different matter I prefer to call instead of texting.

It’s not a rocket science that texting is cheaper and sometimes keep people going on their mobiles and also it’s a way of passing time for today’s youths.

I came across some interesting thing called txtForward earlier today, which I thought was worth a mention here. As its name suggests, txtForward automatically forwards incoming or outgoing text messages to a specified email address.

Now this can encourage young people like me who find dealing with email quite easy than the actual texting on the phone.

But at the same time this could be a boon for the heavy text user who might just want a simple and reliable way to archive their messages. And in case you didn't realize, text messaging is apparently being used by teens to avoid taking phone calls by their parents. How amazing, today’s youth like me are definitely one step ahead than the older ones.

Anyway, the unfortunate state of affair is that most smartphones simply do not treat text messages as important, and hence are generally limited in terms of message-level searching, as well as in their backup and archival.

Available for the BlackBerry and Windows Mobile, the BlackBerry version of the software worked flawlessly for me. Of course, the trial is limited to only 10 forwarded messages, so my experience with it is limited. One downside for privacy advocates is that the emails are sent out via Electric Pocket's servers, though the company gave assurance on its website that no logging, recording, or monitoring of messages takes place.

Still something to cheer up for wireless sector

In the last year as everybody knows because of the lack of money in the market situation has turned towards grimness. In these difficult times everybody tend to take measures whether right or wrong we can’t say for sure. One thing though which is sure is that everybody tries to cut cost in these difficult circumstances and hence results in the some unpopular decisions. Telecomm companies are no different than others and hence quite rightly taken stern steps towards cutting costs. There is some nervousness especially among the investors which gives an impression that spending in the wireless sector will be hot has as well.

Although the certain trends and strategic vibes coming out of the major companies doesn’t suggest so for the time being. Infact I must say wireless infrastructure spending has overtaken wired in the majority of large enterprises.

I can see the main reason behind this increased spending is that companies are well aware that majority of us like to have wireless these days. Majority of the companies, no doubt also expect all their networked equipment to be wireless enabled. This obviously presents a strategic view in front of the companies and investors as a need for mobility and hence the need to upgrade or replace an existing wired LAN.

As everyday passes by in these hard economic times the budget is getting reduced and hence there is a sense of urgency to be more efficient. I might not be very wrong is say that at the moment wireless/mobility sector seems to be achieving that efficiency by taking certain calculated steps.

Companies are trying every possible bit to get the maximum out of the existing or newly planned wireless infrastructure and the technology as such.

Once such company which everybody thought will say goodbye to Wireless is Alcatel-Lucent.
In the highly anticipated strategic announcement by the newly appointed CEO of Alcatel-Lucent, Ben Verwaayen, has announced and hence strongly countered that it is committed to being a major supplier of mobile infrastructure.

I guess Ben Verwaayen see that there is a huge potential in the wireless market and hence despite being pressured by some of its major investors he still wants to go ahead with the spending on the wireless infrastructure major being the LTE.

In the last year whenever I spoke to my friends in different companies I got the view that everybody wants to cut the cost so that they can continue or maintain their R&D section. In my view this is the right thing to do specially for the giants of telecoms. It’s quite simple that R&D projects will enable to develop new and exciting products and hence the revenues.

Based on the above information which gained by talking to different people at the top of the industry I’m 100% confident that companies like Ericsson, Nokia Siemens Network, Alcatel-Lucent etc will maintain its R&D resources and will be ready with LTE products when the market demands. It is very much obvious companies will focus in a more targeted way than in the past and thus may be putting LTE at the very centre of their efforts. The whole ideas to regain the market share and become a leading supplier within 18 months.

340m 'Active' mobile broadband users by 2014

Mobile broadband computing (MBC) has grown very strongly in 2008, to 35m global subscribers. This is forecast to increase almost 10x by 2014, to 341m according to a new report titled "Mobile Broadband Computing" by Dean Bubley from Disruptive Analysis.

Some of the interesting highlights from the report as follows:

• Growth has been driven by cheap HSDPA modems and flatrate data plans.
• The majority of MBC users exploit conventional-seized laptops with separate 3G USB modems (“dongles”). This model will continue to lead despite the growth of netbooks, built-in 3G, WiMAX and MIDs (mobile Internet devices).
• At present, Europe accounts for 50% of global mobile broadband users, reflecting earlier introduction of consumer-friendly USB dongles and ferociously-competitive low-priced HSDPA tariffs.
• “Free” netbooks, provided on a subsidised basis by mobile operators on typical 2-year contracts are popular, but have a limited addressable market.
• By the end of 2011, about 30% of mobile broadband users will be exploiting notebooks with built-in 3G or WiMAX modules. 58%, roughly twice that proportion, will use external modems like USB dongles.
• By 2014, there will be 150m users of notebooks and netbooks with embedded mobile broadband worldwide. In terms of shipments, 100m wireless-enabled laptops will be sold annually by then – but not all will be activated.
• By 2012, there will be 45m users of WiMAX-enabled MBC devices. 11m of these will also use 3G or LTE connections in various hybrid approaches.
• Use of LTE in mobile broadband computing devices will be very limited until 2012. After that, ramp-up will be rapid, reaching 75m units shipped in 2014.
• By 2011, only 40% of mobile broadband users will be on long-term monthly contracts. Most will use prepaid, session-based, bundled or “free” models.
  

Some of the other interesting points from the extended summary as follows:

• Some operators' marketing teams have become over-zealous about competing with fixed broadband. In some markets, HSDPA is now cheaper than ADSL/cable. This is unsustainable, as the cost structures differ hugely. There are physical limits to the capacity of mobile data networks, which will rapidly be reached with the explosion of low-cost traffic. Some cellular networks now see more than 90% of 3G traffic from PCs. Network operators are now hostage to future high-bandwidth Internet applications gaining viral adoption among mobile users.
• Adoption of embedded-3G and embedded-WiMAX notebooks will grow slowly alongside separate “dongle” modems. Predictions of 50%+ attach rates in 2-3 years are over-optimistic; there are numerous practical, commercial and economic reasons for delayed adoption
• To date, most mobile broadband users have connected with an existing notebook PC, together with a separate datacard or USB dongle. Looking forward, a broader set of choices are emerging, with the advent of embedded-WWAN notebooks, small & inexpensive 7-10” sized netbooks, MIDs and the use of 3G handsets as “tethers”. Implicitly, these all compete to some degree against higher-end smartphones as well.
• At present, the majority of mobile broadband subscribers are engaged through
  traditional monthly contracts, typically over 12-24 month periods. However, further evolution is necessary. Disruptive Analysis expects a variety of new business models to emerge and take a significant share of the overall user base, including:
• Session-based access, similar to the familiar WiFi hotspot model.
• Bundling of mobile broadband with other services, for example as an adjunct to fixed broadband or mobile voice services.
• “Comes with data included” models, where the upfront device purchase price
  includes connectivity, perhaps for a year.
• Free, guest or “sponsored” mobile broadband, paid for by venue owners or
  event organisers.
• Incrementing capacity of Networks by perhaps another 10x in the next 6 years will need investment in more spectrum, more cell sites, newer radio technology, better backhaul and dedicated “hotspot” solutions like femtocells and WiFi. Yet in the current climate, these investments face delay, meaning a “capacity crunch” is possible in some cases.

On an unrelated note, More than 25 per cent of the content that workers view each day will be dominated by pictures, video or audio by 2013, according to research by Gartner. Though this does not specifically say mobile content, I think the same phenomenon will be observed in the mobile world and maybe to a larger extent with applications like Youtube already very popular with the mobile users.

Help to decipher the text messages

The world of text messaging is evolving so fast that honestly its becoming difficult for me to keep track of the 'text slangs'. If you are in a situation like me then dont worry help is at hand.

ITPro published an article recently reporting that the 'Post Office' (yup you read it correctly) has released a guide that lists lot of common slangs being used for texting. A word of caution would be that some of the terms are specific to Brits so they may not be applicable in other english speaking countries.

Some of the interesting terms listed are:

• ATM - At the moment
• 4EVA - Forever
• Code 18 - Someone who is bad at using technology
• 404 - Clueless
• BAB - Boring
• P999 - Parent Alert (Note 999 is emergency number in UK. So this would become P911 in US, P112 in Europe and P100 in India)
• GOOD job - Get Out Of Debt job
• Code 11 - Old Fashioned (London specific)
• 143 - I Love You (more commonly used one is ILU)

The guide is available from the Post office site here. (Ftp link for PDF)

There is also a very interesting book called "Txtng: the gr8 db8" that was published not too long ago.

The book is not expensive and I found it very interesting as it contains loads of useful information and statistics. The best thing is that in the end it contains very detailed list of text abbreviations, not only in english but also in 11 other languages (using english charachters though) including Chinese, French, Italian, Spanish and Welsh.

iBangle: Not a phone but great concept

The iBangle is Gopinath Prasana’s vision of a future iPod where the devices have become darn close to becoming jewelry. If you factor in inflation and the cost of Apple products today - might as well call it jewelry because it’ll cost as much. I digress, the iBangle is a thin piece of aluminum (of course) with a multi-touch track pad. To achieve the perfect fit, a cushion inside the ring inflates to keep itself taught against your wrist. Unisex? Maybe.

If this concept becomes reality, it would be just mater of time before a phone is rolled in along with this.

The wearable concept is also puched in the Nokia concept phones like the Nokia 888 and Morph.
