Mobile Phones 'Ad-Hoc Networks'

Picture Source: Daily Telegraph

Couple of years back I blogged about MCN and ODMA concept. Another variation of this idea is now in news again.

From the Daily Telegraph:

Australian scientists have created a mobile phone that can make and receive calls in parts of the world that would normally have no reception.

The phones contain a built-in mini-tower that allows them to connect to other phones via Wi-Fi and create their own network.

Researchers at South Australia's Flinders University devised the phones to work in the event of a natural disaster or terrorist attack when normal mobile phone services had been cut off.
Dr Paul Gardiner-Stephen said the phones had been tested successfully in the remote Outback where mobiles cannot pick up a signal.

"There was absolutely no infrastructure or support for the telephones so they were acting entirely on their own to carry the calls," he said.

The phones are unlikely to replace existing mobile systems, but could be combined to create fail-safe communication.

"One of our dreams is that every phone will come out with this one day so that if there is a disaster anywhere in the world everyone's phones will then switch over to this mode as a fallback," Dr Gardiner-Stephen said.

"When the infrastructure is knocked out we still provide good service while the traditional mobile phone network provides no service."

At the moment, the signal between phones is limited to a few hundred yards, but the team hopes to expand the range in the future.

I dont see them becoming reality for quite some time to come but its an interesting concept.

This is not the first time this idea is being proposed. As I have discussed, ODMA was intended to do something similar but did not take off. MANET's are other areas that have been worked on for quite some time and you can find good ideas and journal papers. There is also this paper talking about Ad-Hoc networks for mobiles using Bluetooth.

In fact going many years back, Iridium idea was launched with something similar in mind. I remember reading jornal papers back in 1996 that mentioned that Iridium phones will work like landline phones when you are in your house and will work as cellular when out of house and in an area with cellular coverage. If there is no cellular coverage then it will rely on Satellite communication. Of-course in those days nobody thought data usage will become this popular and so it was focussed on voice. Still I cannot see this happening for many years to come.

6 Billion Mobile Connections by June 2011

Just saw on Tomi's Blog that the number of active connections worldwide reached 5 Billion.


According to Wireless Intelligence:



The number of global mobile connections surpassed the 5 billion mark this week, according to new Wireless Intelligence data. The milestone comes just 18 months after the 4 billion mark was reached at the end of 2008 and is in line with our earlier forecasts. We predict that the 6 billion global connections milestone will be achieved in the first half of 2012. According to our data, the mobile penetration rate on a global basis at the 5 billion mark was 74 percent, compared to 60 percent at 4 billion. The highest penetrated region is Western Europe on 130 percent, while the lowest is Africa on 52 percent. Eastern Europe (123 percent) is the only other global region to have passed 100 percent mobile penetration.


The main driver of growth continues to be the Asia-Pacific region, which accounted for 47 percent of global mobile connections at the end of Q2 2010 (see table). This is up around 5 percent from Q4 2008 when the 4 billion connections mark was reached. Growth in Asia-Pacific is due mainly to ongoing growth in China and India – the world’s two largest mobile markets – which offset slowing growth elsewhere in the region in markets such as Pakistan and the Philippines. Growth was slower in mature markets such as Europe and North America, which now account for around 27 percent of global connections, compared to over 30 percent 18 months ago.



To Summarise the Mobile Subscriber growth:

Sisvel's LTE Patent Pool

One of the things I wanted to blog from the LTE World Summit was the new Patent Pool by Sisvel. In past I have blogged about the patent pool initiatives from Via Licensing Corp. and MPEG LLA LLC.

Based on Sisvel's presentation, they have the most number of companies in their pool which will make them the dominant pool and give the required clout to negotiate licensing fees.

The following is from PC World Magazine:

Typically, patent pools are managed by specialized companies that don't own intellectual property themselves. They set up licensing programs, collect license fees and distribute the proceeds to member companies. In the case of LTE, three of these -- Sisvel, Via Licensing and MPEG LA -- are vying to form a pool that represents a critical mass of LTE patents.

Sisvel, an Italian company that also operates a patent pool for MPEG audio technology, this week claimed it had brought together 32 significant LTE patent holders, the largest number of any of the three patent-pool companies. "With the kind of scale that we're talking about here ... the pool could really be close to a one-stop shop," said Sean Corey, IP counsel for Sisvel US.

Meanwhile, MPEG LA says about 15 companies are working with its pool program, but added that they include some of the major players in terms of patents and market share. "There's a critical mass there," said Bill Geary, vice president of business development at MPEG LA. Via Licensing says 24 patent holders were actively discussing licensing terms and conditions at its last meeting of stakeholders, he said.

Formation of the pools is still at an early stage, with none of them yet operating and no patent holders publicly announcing their affiliations. But while all three say they are months away from operation, Via claims it has the most aggressive program. After kicking it off in January, the company could get its patent pool running in as little as 12 months, said John Ehler, Via Licensing's director of wireless programs. MPEG LA has been working on its own pool for about two years and hopes to have it in operation next year, Geary said. Sisvel's Corey said it takes between 18 months and two years to get a program going.

All three companies want to have the biggest pool, to make it easy for vendors large and small to license everything they need. In this way, patent pooling should help to accelerate adoption of LTE, the patent-pool promoters said. It could also attract a broader range of companies, such as consumer electronics makers and embedded device manufacturers, to the fast networks.

Patent pools are likely to have a bigger impact on embedded devices than on smartphones, according to Robert Syputa, an analyst at research company Maravedis. The market for machine-to-machine radio devices such as smart electrical meters is more price-sensitive than for mobile data products that consumers use, he said. Easier licensing may also draw in a wider range of vendors of such products, he said.

It's important to get pools organized early in the adoption cycle of a technology, Syputa said. If the commercial marketplace advances too far, too much intellectual property may become locked up in one-on-one licensing agreements between companies, he said. This happened with 3G, but with LTE, patent holders still have time to do it right, he said.

At least one important LTE patent holder, Ericsson, has said it will only sign bilateral license deals. Having three pool efforts in progress seems to complicate matters where just a single sanctioned one might be preferable, Syputa said. But even three pools would be preferable to a series of individual agreements, he said.

The IPR battle is not simple and straightforward as mentioned above. The following is from Daily Wireless Blog:

Qualcomm and its GSM technology counterpart InterDigital together control 40% of the LTE patent pool, with 19% and 21% of total patents, respectively, says Informa. Most LTE supporters want the royalty bill to be a one percentage of the sale price in an LTE handset, but IPR owners appear to be pushing it closer to 5% – similar to Qualcomm’s IPR tab.

Ericsson, the world’s largest wireless infrastructure manufacturer, claims to have 25 percent of the essential patents to Long Term Evolution (LTE) networks, making the vendor the single largest IPR hold in LTE. Most of the huge IPR holders in W-CDMA – Qualcomm, Nokia, Ericsson and InterDigital – are also claiming a big share of the LTE patent base.

Ericsson claims contradict a survey from Informa regarding essential IPR holders. Informa estimates Ericsson is much lower in the IPR ranking, behind Qualcomm, InterDigital, Samsung and Huawei in total patents, with emerging vendors such as Huawei also contributing 4G development research.

Ericsson believes it holds nearly 24 percent of awarded essential patents for LTE. Informa estimated that Ericsson holds about 7 percent.

Unlike Qualcomm – which by almost everyone’s calculations remains the leader in essential IPR – Ericsson is favouring a patent pool approach, which would set the total royalty rate for combined patents at under 10%, says Caroline Gabriel.

HSPA+ rollout updates, July 2010

Its been a while since we talked about HSPA+ rollouts. In between we did hear about the data rates bumping upto 84Mbps and even 168Mbps.

The good news is that now there are actual rollouts happening with 42Mbps HSPA+ and others in pipeline.

According to The Register:

In Japan this week, the smallest operator, eMobile, 'soft launched' Japan's fastest network. Using Ericsson kit, the fourth cellco made its new HSPA+ (high speed packet access) services available to select users, promising theoretical download speeds of 42Mbps. This iteration of HSPA+ has only been adopted by a few carriers so far, notably Australia's Telstra.

The full commercial launch of eMobile's data-driven network, in metropolitan areas such as Tokyo, Tokai and Osaka, will take place by year end.

According to Wireless Intelligence, the small player has 2.5 million subscribers - just 2.3 per cent market share - but enjoyed a high year-on-year growth rate of 52.5 per cent to mid-2010. It originally relied on an MVNO model but started rolling out its HSPA network, offering flat rate data services, in 2007. It upgraded to 21Mbps last summer using equipment from Huawei and promises LTE by 2012.

Bulgarian mobile carrier M-Tel demonstrated download speeds of 42 Mbps reached via Dual Carrier HSPA+. The technology will be introduced in Sofia by the end of this year, doubling the current maximum download speed of 21 Mbps. Thanks to the 42 Mbps download speed, the customers of M-Tel will be able not only to surf the internet at high speeds, but also watch 3D and HD TV channels through the mobile network. With the new Dual Carrier HSPA+, it will take about two and a half minutes to download a 750 MB movie, compared to four hours and 45 minutes via UMTS. With the HSPA+ technology, a movie of the same size would be downloaded in five minutes and 16 seconds. M-Tel introduced the HSPA+ technology which provides speed for data transfer up to 21 Mbps last year in Sofia. By the end of August, HSPA+ will also be available in Varna, Plovdiv and Burgas.

In Saudi Arabia, Mobily successfully completed trials for the coming upgrade of its state-of-the- art evolved high-speed packet access (HSPA+) network testing speeds of 42 megabits per second (Mbps), according to a statement issued by the company. The 42 Mbps speed, expected to be rolled out in major cities in the interim, will be the first major speed upgrade since Mobily became the first operator in the region to launch HSPA+ towards the end of 2009 at speeds of 21 Mbps, and closed the year with one million customers subscribed to its high-usage bundles, and an overall base of 18.2 million.

Mobily’s HSPA network has given a much needed boost to household Internet usage in the Kingdom with household penetration rates more than doubling from around 14 percent for end of 2008 results to 32 percent for yearend 2009, according to the Communications and Information Regulatory Commission’s annual report.

According to the same report, wireless broadband grew 488 percent to 1.41 million wireless broadband subscriptions and representing 51 percent of all broadband connections in the country, as compared to a 47 percent share for ADSL. Of those 1.41 million wireless broadband subscriptions, one million were on Mobily’s network, giving the company a market share of 70 percent market of all wireless subscriptions and 36 percent of all broadband connections in the Kingdom.

Etisalat, Egypt, in partnership with Hawei Technologies Co Ltd, has launched its HSPA+ Phase 2 network in EGYPT. This new technology has already been deployed in the Etisalat Misr network. The existing network has reached an average download speed at 41.73 Mbps. HSPA+ Phase 2 increases Etisalat mobile broadband network capacity to support speeds of up to 42Mbps, from 21Mbps previously.

Indosat just launch fast Internet access service DC-HSPA+ 42 Mbps in Surabaya, Indonesia. Indosat claim the DC-HSPA+ services could provide download speeds of up to 42 Mbps for customers Indosat Mobile Broadband and IM2. Previously, these service has only presented to Indosat customers in Jakarta.

There are rumours that in USA while everyone is concentrating on LTE, T-Mobile has been planning to upgrade to HSPA+ to improve its speed. We will have to wait

My crazy ideas and Softbank's free Femtocell (+ ADSL and maybe Femtocalls)

Couple of years back I blogged about end users making money by allowing operators to deploy Femtocells. I cant remember but someone did say that it was a crazy idea. Well Softbank, the Japanese operator is doing something similar.

Rather than giving cashback, they are giving in free ADSL connection. The customers will have to sign a 2 years contract though. With free ADSL connection and a Femtocell, surely the end users are winners. They only have to invest in electricity which would not be a lot. The operator can end up as a winner as well as they get a better coverage by deploying open access Femtocells.

According to Will Franks, CTO of Ubiquisys, Softbank can afford to do this because femtocells are cheap and the IMS based architecture used by Softbank allows easy scalability. They are expecting upto 200,000 femtos to be rolled out in this scheme this year.

My take is that this is going to be the case but there will always be people who would be reluctant to get the Free Femtos + ADSL deal. They could instead be tempted with cashback if someone makes or receives call by accessesing their femto or instead free calls can be offered to the owner while he is camped onto his residential femto. A combination of both would be a good business case as well.

Anyway, Softbank is setting a good bar for other operators to compete with.

Mobile Developer Economics 2010 and Beyond

A new report "Mobile Developer Economics 2010 and Beyond", offers many new insights into mobile developer mindshare, and analysis into every touch point of the developer journey, from platform selection to monetisation. The research is based on a set of benchmarks and a survey across 400+ developers globally, segmented into 8 major platforms: iOS (iPhone), Android, Symbian, BlackBerry, Java ME, Windows Phone, Flash Lite, and mobile web.

In terms of developer mindshare, our research shows that Symbian and Java ME, which dominated the developer mindshare pool until 2008, have been superceded by the Android and iPhone platforms. Despite Symbian remaining in the pole position in terms of smartphone market penetration, ‘out-shipping’ iPhone 4 to 1 and Android many-times to 1, the signs of dissatisfaction with the way the Symbian platform has evolved have long been evident.

Indeed Android stands out as the top platform according to developer experience, with close to 60 percent of developers having recently developed on Android, assuming an equal number of developers with experience on each of eight major platforms. iOS (iPhone) follows closely as the next most popular platform, outranking both Symbian and Java ME, which until 2008 were in pole position.

The report can be downloaded from here and is embedded below for convenience

Femtocells data cap and offload dilemma

I recently heard Prof. Simon Saunders (who has a much impressive background that i thought of) at Cambridge Wireless International conference speaking on Thinking Networks.

One of the things mentioned that struck me is how convenient it would be with femtocells to offload the data on the internet directly without going through the operators core. This would mean less data on the backhaul for the operators and since data would have to travel through less nodes, the speed and reliability could be higher.

There is a slight problem though. In the recently concluded Femtocells World Summit (which I have blogged a lot about), AT&T has been harping about its data caps while using Femto. AT&T wants that the Femto's should mainly be used for voice and for data the users should generally switch to using WiFi. Their reasoning is based on the fact that they are not allowed to perform data offload as mentioned above due to FCC regulations. In fact the same problem may be present in other countries and would hamper the Femto growth in time.

Femtocells are better for data usage as I have mentioned in past because they provide seamless coverage and better data security. It should also be pointed out that the battery drains faster when using WiFi as compared to the mobile Internet.

When a user uses Femtocell, he is already using his broadband data allowance and if there is additional restriction placed in terms of data caps on the Femtocell, the users may just revolt and avoid using Femtocells at all.

Voice coverage advantage is good but users may prefer to switch operators if its just voice that they are using Femtos for. While the use of fixed line phones have decreased in the past (thanks to voice bundles on mobile), some users are switching back to using landlines because of the voice clarity and no reception problems.

The Femto manufacturers and the operators will have to act fast if they want their future predictions to come true.

Mobile Apps a fad

It has always been a debatable issue as to how big the mobile Apps market is. Right now it is huge and seems to be growing fast.

Dean Bubley of Disruptive wireless on the other hand thinks of Apps as a fad that will die sooner or later. He re-iterated the point he made back in February that:

a) There is no mobile Internet, just the Internet on mobile. The vast bulk of usage of the Internet on mobile devices mirrors the usage on fixed networks and from PCs. In particular, there is a huge amount of mobilisation (with tweaks, yes) of existing social networks (Facebook), email and content downloads (YouTube). With the exception of mapping, most mobile-specific Internet services are niche and useless, eg Foursquare and Gowalla.

b) I'm still expecting that users will get bored of hundreds of applications, and will have a few well-chosen ones - most of which should have been in the core OS when it left the factory anyway. eg on an iPhone - Facebook, RSS and Skype clients. The "long tail" of apps will be of limited interest to most mid-late adopters apart from the occasional game or advertiser-sponsored thing. I'd expect <$2 of spend on apps per month once high-end smartphones get to, say, 30% penetration, perhaps <$1

Mind you, maybe I'm biased. I haven't bought a mobile application for personal use since a Java game in 2005, and don't have any payment mechanism registered with iTunes.

I tend to agree with him but I think that the Apps threshold will be slightly higher like $5 per month which would be stealthily provided by the operators mainly through offers like "free apps allowance" kinda stuff.

This article reminds me of the dilbert joke (below) that other professionals can also make money around the Apps marketplace:

Iridium making good progress

It was interesting to see Iridium phones being displayed by Cambridge Consultants in the Cambridge Wireless International Conference. Iridium has gone through some rough times and I remember reading how Satellite communications will change the world but it never came to pass.

Its good to read that the OpenPort terminals are proving effective and can help save lots of money to shipping companies.

* Sprint - Sprint Airave

* Vodafone - Vodafone Sure Signal

Winner:

AT&T - 3G MicroCell National Deployment

“AT&T’s 3G MicroCell deployment with Cisco caught the judges’ eyes for two crucial reasons. First and foremost, it emphasised the importance of the customer at the heart of the femtocell experience, positioning technology very much as an enabler, rather than an end in itself. Secondly, the deployment is on a national scale, which given the US market’s size adds an additional layer of complexity,” agreed the judges.

Category 7: Contribution to femtocell standards

Shortlists:

* Airvana - Airvana Standards Team led by Doug Knisely, VP of technology

* Alcatel Lucent - Martin Warner- A catalyst in driving 3GPP femtocell specifications

“The Continuous Computing and picoChip LTE reference design is a great example of an enabling technology that is necessary to kick start development of LTE femtocells. The timing of this reference design is critical for the introduction of LTE femtocells as operators begin to rollout the first LTE networks. At the same time there is a growing understanding of the importance of multi-tier cellular architectures as we move from 3G to 4G and as networks begin to cope with user demand for capacity. The judges wanted to recognize the role of this crucial component in what is likely to become a necessary part of future 4G networks,” agreed the judges.

Category 9: Judges’ Choice

Shortlists:

* Alcatel Lucent - Wilson Street: Alcatel-Lucent’s wireless technology showcasing smallcells living and working with macrocells for the community of Wilson Street

* Ubiquisys - The World’s First Sub-$100 Femtocell - the G3-mini

* Vodafone - Vodafone Sure Signal

Winner:

Vodafone - Sure Signal

“While we in the industry have known about femtocells for many years, the wider public have been unaware of their existence and benefits. The Vodafone marketing campaign changed all that. In a well-crafted and multi-faceted campaign they showed consumers how they could achieve coverage in their home and changed the role and perception of cellular communications. They have done a great deal to advance the success of femtocells and fully deserve to be recognised for this,” agreed the judges.

Category 10: Individual contribution to Femto Forum activities

Shortlists:

* Joshua Adelson, Airvana

* Gibson Ang, GENBAND

* Gordon Mansfield, AT&T

From an impressive shortlist, the judging panel selected Gordon Mansfield, Executive Director at AT&T, as the individual who has made the single biggest difference to the progress of the Forum. Gordon has been a major force in developing consensus positions among operators and other stakeholders on a range of femtocell related issues. He has been a regular contributor at Femto Forum plenaries and sponsored conferences, as well as being a tireless promoter of femtocells to the wireless industry as a whole by speaking in support of femtocells at numerous industry events. Besides his own time commitments he has worked to assign the right AT&T individuals to contribute in the working groups and SIGs of the Femto Forum. We are very pleased to be able to recognise his dedication to the worldwide acceptance of femtocell technology through this award,” said Simon Saunders, Chairman of the Femto Forum.

Category 11: Chairman’s award

Winner:

Karim Sharf, TraC

"Most of the Femto Forum’s work is driven by the efforts of individuals from within our member organisations and a huge number have contributed their time and skills to the Forum in the past year and all deserve my considerable thanks. However, one of our key goals we had in the last year was to make tangible progress towards our vision of an open, interoperable ecosystem for femtocells. To that end, in March we ran the first plugfest for UMTS femtocells, which was widely supported by over 20 vendors. Karim Sharf was instrumental in supporting and coordinating that process and his level of contribution to the Forum's aims has been outstanding,” said Simon Saunders, Chairman of the Femto Forum.

NTT DoCoMo for LTE Femtocells next year

Its been nearly couple of years since I blogged about starting LTE with femtocells initially and then moving onto Macro network. It had initial momentum but didnt take off for one reason or another. In the ongoing Femtocells World Summit, Yoshiyuki Yasuda, NTT DoCoMo's managing director said that they plan to roll out LTE Femtocells next year mainly to fill the coverage gaps in the LTE Network they will be rolling out later this year.

Those who read this blog regularly would have noticed my recent post about NTT DoCOMo's LTE initiatives here. I have also been promoting LTE femtocells idea as can be seen in my blogs here, here and here. My belief is that femtocells could be very valuable to iron out the problems present in devices, networks or the technology. Also they provide seamless coverage and offer better data security.

Light Reading has interesting analysis on this topic:

Which vendors can serve up the LTE femtos in time? NEC Corp., which is already one of DoCoMo's LTE vendors, has revealed plans for an LTE home base station that will be available for friendly user trials at the end of 2011, and a commercial product is expected in 2012.

Other vendors that are involved in DoCoMo's LTE rollout that could have a shot at meeting the carrier's next-gen femto demands are Fujitsu Ltd., Ericsson AB, and Nokia Siemens Networks, and Stoke Inc. , which supplies an LTE base station aggregation gateway to the Japanese operator.

DoCoMo's current femto vendor is Mitsubishi, which supplies little 3G home base stations to DoCoMo for its MyArea service that launched in November 2009.

DoCoMo's Yasuda said that when the carrier wants to deploy LTE femtos in the 2011-2012 timeframe, it will have deployed 1,500 LTE macrocell base stations during 2010 and 2011. By 2013, it plans to cover 30 percent of the population with LTE. By 2014, DoCoMo plans to cover 70 percent of the population with 15,000 LTE base stations.

'Internet Kill' switch and IPv9

Slightly off topic today as I was going through the pile of information and I caught attention of this news article that for some reason has not been reported by major newspapers. The article says that the president of USA will have the 'Kill' switch to kill off internet (temporarily i guess) in case of a major emergency like war, etc. Joseph Liberman who proposed this idea has since then backed away saying that he meant that parts of Internet can be disconnected like they do in China.

This brought into attention the other article I was going through about IPv9. Yes thats correct, I did write IPv9. I first heard about IPv9 back in 2004-5 but then it was dismissed as nothing serious. Apparently Chinese government backed Ministry of Information Industry (MII) has been promoting this IPv9. According to an old TelecomAsia.net article:

Back in July 2004, reports of a Chinese IPv9 prompted a bewildered reaction from internet godfather Vint Cerf. 'What could this possibly be about‾ As far as I know, IANA [Internet Assigned Numbers Authority] has not allocated the IPv9 designation to anyone. IPv9 is not an Internet standard. Could you please explain what is intended here‾" he wrote in an email to China's internet leaders.

The idea was dismissed as a "rogue" project with no official backing. But it is back on the table led, now as then by Xie Jianping, the head of the Shanghai Universal Institute of Chemical Technology and more recently in charge of the decimal network standards team in the MII's science and technology department.

The project returned to prominence at a press conference at the unusual location of the Party Central School in Beijing two weeks ago, where Xie announced that the networking technology had been successfully tested by China Netcom and the Ministry of Commerce.

He asserted that the project is all about China wresting control of its own IP networks away from US dominance for which, he claimed, China was paying 500 billion yuan a year.

The system reportedly uses numerical addressing to make China "the only country able to unify domain names, IP addresses and MAC addresses" into a single, metric system, according to Xinhua. Without any explanation, Xinhua said it also made China the only country outside the US "to have root servers and IP address hardware connectivity servers and its own domain name, IP address and MAC address resources".

In an interview with a skeptical Sina reporter, Xie and denied the project was another Hanxin - a reference to a fraudulent state-backed chip project.

"Our IPv9 has gone through testing and assessment," he said adding that he could not give any more detail but would "make public some material at the necessary time."

But the system, or what little is known of it, has plenty of doubters at home. Sina said critics of the system complain that turning domain names and brand names into numerals is a "backwards step" for the net.

The fact that the decimal network appears to asset control over root servers is bound to alarm internet governance bodies around the world.

And whatever else might be said about it, the project is clearly backed by the MII. "IPv9" raises more questions than answers.

So it looks like the Chinese government may have been expecting some 'Kill Switch' in the future by the US government and is probably creating a backup based on a new approach so that the users within China remain connected to their Internet.

Any thoughts and opinions are more than welcome...

Say no to texting and yes to Swype

Tapping out a text message could become a thing of the past due to new 'Swype' technology.

Instead of pressing individual letters, mobile users drag their finger from one letter to the other in a fluid, faster motion.

The computer then calculates which word was intended by the combination of the letters touched upon.

The movements do not even have to be precise because the software can work it out.

According to U.S. inventor Cliff Kushler, 'Swype' can increase the speed of even the most nimble texter by up to 30 per cent

He said the technology could have an enormous impact and be used anywhere people have to use a keyboard, such as video games, sat-nav devices and ticket machines.

Mr Kushler has already invented T9 software, or predictive text, which guesses the word people are thinking of as they text, and thinks 'Swype' is the next step.

'We've squeezed the desktop computer, complete with keyboard and mouse, into something that fits in a pocket,' he said.

'The information bandwidth has become very constricted. I thought, if we can find a better way to input that information, it could be something that would really take off.

'The most important thing was that it could accurately figure out which word you wanted to spell.

'It needed to work no matter what.'

Palm pilots sought to liberate mobile users from texting, but they still demanded that you write each letter on to the device with a special plastic pen.

T9 technology went one step further, and now 'Swype' can improve even that. In demonstrations, hurdles like capitals and double letters are overcome by pausing or doing a squiggle, while spacing and punctuation are automatic.

Won Park, director of United States technology sourcing at Samsung said: 'It could become the de facto standard for tablets, next-generation TVs or next-generation remote controls. It has tremendous potential.'

Swype is now being used on seven smartphones in the U.S. across all major mobile phone companies and by the end of the year, Mr Kushler says its software will be on more than 50 models worldwide.

Deals with Apple for the iPhone are some way off, as is the technology's arrival in the UK.

Samsung v/s Apple Display War

In launching the new iPhone at the Worldwide Developers Conference in San Francisco last week, the Apple front man claimed the screen's IPS LCD technology, developed by LG and Hitachi, also offered superior colour resolution and was “quite a bit better” than Super AMOLED overall.

“You can‘t make an OLED display with this type of resolution right now,” Jobs said on stage. “Retina Display is going to set the standard for displays for the next several years. We don’t think anybody’s going to come close.”

But Samsung disagrees, claiming that the difference in the total number of pixels over Super AMOLED's 800 x 480-pixel resolution is all but negligible to the naked eye, and pointed instead to Super AMOLED's emissive lighting and its ability to deliver far better colour and contrast than more traditional backlit screens like the Retina Display.

"The visibility difference is only 3 to 5 per cent. But raising resolution to that level increases battery consumption by 30 percent,” a Samsung spokesperson told the Korean Herald. “Structurally, IPS LCD technology cannot catch up with AMOLED display technology,” .

One of Super AMOLED's chief attractions is the reduced strain on the battery thanks to that lack of backlighting, with Samsung's new Wave smartphone offering double the battery life of the iPhone. In addition, the Samsung screen offers a contrast ratio thought to be around 1,000,000:1, dwarfing the iPhone's figure of just 800:1.

According to Jobs, the iPhone's screen's 326 pixels per inch meant it had a higher resolution than the human eye “The display is your window into the internet, into your apps, into your media, into your software,” he said. “Retina Display is the best window on the planet.”

Its good to see the Mobile Display evolving but not sure if everyone cares about it. There is a good comparison of AMOLED v/s LCD with lots of pictures here, which will give you a good idea. More details here as well.

MBMS, Digital TV and IP Triple Play in China

Apparently according to this report by Xuefei (Michael) Peng, MBMS is alive and kicking in China with around 200,000 users already. I cant find more info so if anybody who can fill more info is more than welcome.

The government of mainland China has formulated a general plan to launch triple-play services, integrating telecom networks, broadcast and TV networks, and Internet together.

From 2010 to 2012, China will focus on the trial integration of broadcast and TV services and telecom services (including Internet services), dealing with any related policies. From 2013 to 2015, based on the trial experience, China will promote the integration nationwide.

In the coming five years, various sectors will prepare in different ways to meet the goals stated in the general plan. Telecom operators such as China Mobile, China Unicom, and China Telecom will invest more to promote IPTV services and accelerate FTTX deployment. Meanwhile, broadcast and TV operators will accelerate cable-TV network integration and interactive TV services development and will more actively develop value-added Internet services.

Broadcast and TV operators are currently strong in video content and wireless broadcast, while telecom operators own two-way fixed-line networks, mobile networks, and Internet services.

The differences between broadcast and TV operators across different regions and the uneven distribution of telecom fixed-line networks and mobile networks can offer cooperation opportunities.

Notably, almost all provinces of China already have launched IPTV services. The total number of IPTV service users in China has exceeded 5 million. However, problems with IPTV content must be solved, and the price for IPTV services also needs to be lowered to attract more users and compete with digital TV.

Meanwhile, the transformation of cable-TV networks from one way to two way has been sped up. Two-way cable-TV networks now cover over 24 million users. In the coming three years, broadcast and TV operators will invest over US$5 billion to continue to change 100 million one-way cable-TV links into two-way cable TV.

Eventually, through cable-TV networks, broadcast and TV operators hope to run Internet access services. This has been in trial use in some provinces. In order to run Internet access services, however, broadcast and TV operators need to rent bandwidth from telecom operators, greatly increasing the potential cost of service.

Another aspect of the triple play involves the conversion of mobile services to triple play. Mobile-phone TV is an emerging service in China. Up to now, mobile-phone TV services based on the China Multimedia Mobile Broadcasting (CMMB) standard have reached 1.5 million users. However, the current CMMB standard only supports one-way communication. So the users can only receive broadcast-TV programs via mobile.

On the other hand, mobile services based on the broadcast multicast Multimedia Broadcast Multicast Service (MBMS) standard serve about 200,000 users. The growing 3G user base will convert to the MBMS standard. Additionally, the government policy will affect the mobile-phone TV market too. So it is not clear yet which mobile-phone TV standard will dominate the industry in the future.

Running live networks on Renewable Energy sources

We have been hearing for years that Solar energy could be used to run remote BTS/Node B so i was glad to see that they are deployed in practise and are working well. It was very interesting to see hear Pradeep de Almeida, Group Chief Technology Officer, Dialog Telekom Plc, Sri Lanka in the LTE World Summit.

The picture above lists the features from an ideal renewable energy powered BTS or Node B (or eNodeB for that matter). The picture below shows one of the real life deployments in Sri Lanka.

It was very interesting to hear that the power generated using the Solar and Wind approach is generally in surplus and this extra energy could be sold to the power companies or can be used to provide an outlet point where the people can come and charge their phones.

The return of investment (ROI) for these kind of deployments could be as low as 2 years and can be as high as 4 years. The time for ROI will be reduced for countries where diesel (used for generators) is expensive and will be increased when diesel is cheap. That is why we may not find environmently friendly approaches in Middle East for quite some time because of cheap oil.
