2008 Mobile TV Roundup

2008 has been a bad year for Mobile TV. All the hype and expectations from 2007 died down early this year. From that point it has been a downward spiral for the Mobile TV market. Mobile Europe has a good summary on Mobile TV in 2008. Interesting highlights as follows:
  • The most high profile event of the year was probably a bad news story: the demise of MFD [Mobiles Fernsehen Deutschland]'s DMB-based service in Germany, finally withdrawn after struggling for the best part of two years to increase viewer figures, and as MFD shifted its strategy towards DVB-H.
  • The one big success has been the continued growth of 3 Italia's DVB-H service, cunningly launched on the back of the 2006 football World Cup (won by Italy), which now has more than 850,000 subscribers and has added a free to air bouquet to its pay TV offering
  • Yann Courqueux, director of broadcast development, IPTV and mobile TV at Thomson, is optimistic about the potential of the Russian market, where three operators are set to launch services in 2009
  • On the technology side, supporters of DVB-H and DVB-SH feel 2008 was the year when their standard established a clear lead over its rivals.
  • The consumers have noticed during 2008 has been the appearance of a new generation of handsets and mobile devices, including the Nokia N96 and the BlackBerry Storm.
  • Another service that some believe will be crucial to the prospects of mobile TV in the longer term is DVR capability, but there were no significant steps forward in this area in Europe during 2008.
  • It will be at least two more years before we begin to see mass adoption of mobile TV across Europe

2008 Femtocells Roundup

Think Femtocell has a good review of Femtocell activities and progress in 2008. Some interesting highlights:
  • Didn’t meet expectations given by some of the more enthusiastic commentators, but overachieved on many industry expectations.
  • Several vendors have commercially applicable products, others are rapidly catching up.
  • The early commercial launches of 2G CDMA femtocells in the USA appear to have gone reasonably well.
  • The Femto Forum has done well to ensure that the industry enters the standards meetings with one voice.
    • There remain two architecture options – one directly compatible with todays 3G GSM/UMTS core network and services
    • the other targeting the future IMS/SIP based solution
  • The first is now effectively completed within 3GPP Release 8, although interoperability between femtocell vendors will need testing and clarification before entirely complete.
  • Operators have set very demanding price points, which won’t be achieved until volumes dramatically increase. Prices for complete units are said to be below $200 already, with the target $100 achievable within 18 months
  • The primary competitor for femtocells is WiFi, specifically the UMA standard which can handover calls between 2G/3G and WiFi. UMA requires special handsets, which until recently have been fairly limited and restricted to 2G. Although its been around for a few years, it seems only the last year that we’ve seen more and more handsets with WiFi appear – and low power WiFi at that.

Predictions for 2009

  • Commercial launches, more in the second half of 2009
  • SIP/IMS femtocell architecture adopted in US and Japan
  • 3GPP standards incorporate SIP/IMS femtocell protocols in Release 9
  • “Over the top” WiFi-style services, such as Fring and TruPhone, will become more popular – driven by greater focus on cost cutting and improved 3G data rates/quality.
  • LTE femtocells won’t become reality until at least 2011, operators will continue to prepare and roll out initially using traditional macrocellular basestations.

WiTricity on display at CES 2009

No more batteries, no more chargers and no more wire spaghetti. This is the future promised by "wireless power", a means of broadcasting electricity through the air to laptops, iPods and other gadgets without the need for cables and sockets.

Untethered lighting, audio speakers and digital picture frames are expected to be among the first commercial products demonstrated in Las Vegas this week at the International Consumer Electronics Show, the world's biggest gadgets tradeshow.

Experts believe this is just the beginning and that eventually wireless electricity - dubbed "WiTricity" by some - could do for battery life what WiFi did for the internet. In a world without wires, laptop users in cafes and airport terminals would be inside an "electricity hotspot" and no longer have to delve past legs, bags and furniture in search of an awkwardly located socket.

Among the companies showcasing the ambitious technology at CES is
PowerBeam. Its system turns electricity into an invisible laser, then literally beams it, as heat, across the room to a solar cell that converts it back into electricity.

David Graham, the co-founder of PowerBeam, told the Observer: "We're going to delete the word 'recharge' from the English dictionary. If your cellphone is recharging on your desk all day, you won't be thinking about it."

The Silicon Valley company can currently use a laser to generate about 1.5 watts of power to a solar cell 10 metres away. This would be enough to power an electronic speaker or small LED (light-emitting diode) lights, but not enough to operate a laptop, which requires an estimated 30 to 50 watts. However, Graham said that the technology could comfortably be scaled up.

PowerBeam insists its laser does not pose a risk to users' health because it is simply moving heat from one place to another. Graham said that, if someone walked through the beam, it would shut down within a thousandth of a second, then restart once the path was clear.

This is a powerbeam demo on Youtube:

Happy New Year 2009

Happy new year to everyone. May the new year see lots of new technologies succeed. May we see lots of new mobile phones with innovative technologies. May we see operators offering bigger bundles cheaper. May we see the technologies being simplified and understandable by everyone. May we see WiMAX and LTE co-exist peacefully. May we see lots of nice new books available at a much cheaper price :) May we see nice new mobile apps making our life simpler. May we keep reading and writing blogs and exchanging ideas.

Bar Coded Train Tickets on Mobile



The Association ot Train Operating Companies has announced that all its franchisees will be able to take orders from train travellers straight from their phone and receive their tickets literally seconds before trains depart.

The system uses Masabi's tried and tested mobile ticketing solutions which relies on a barcode image that is scanned by the appropriate device(s) - as used by City AM newspaper and for V-fest events.

There's no need to sign-up and fast repeat purchases can simply be done using the card's CVV.

In addition, you won't be charged extra for using the sytem which uses US Government certified security encryption and when things go wrong, the new barcodes contain enough ticket information to allow alternative systems to validate tickets.


Ben Wittaker of Masabi said that "Once you send your text message to purchase your ticket, you will receive a response with a barcode reference, which can be scanned by inspectors."

Commentators hope that the service is more reliable than the UK train network and more secure than Transport For London's own Oyster system which has suffered a number of security scares in the past few months.

National Express, Heathrow Express and Chiltern Railways have already adopted the Rail Settlement Plan. This will lay the foundations of the rail ticketing body in charge of drafting the UK-wide standard which will oversee the use of tickets printed outside train stations.

Following successful trails with various train companies Masabi has worked with the Rail Settlement plan - the body that cross charges networks for ticketing to create an open standard for train tickets carrying bar codes to be accepted across rail franchises - enabling tickets to be printed out at home, or even displayed on mobile-phone screens, and used on journeys between network operators.

Selling tickets is an expensive part of running a rail franchise, and nearly 90 per cent of tickets are still sold at stations using ticket machines or at traditional windows.

Trials run by Masabi, who specialise in rendering bar-code information on phone screens, have apparently demonstrated that customers will happily buy tickets using their mobile phone - either while travelling to, or on arrival at, the railway station. Masabi's Java application stores the customer's credit card details locally, so the user just keys in the three-digit code from the back of their card along with origin and destination, and the ticket is bought and delivered over SMS or data connection where available.

But the standard also allows for bar codes to be rendered on other devices, or printed out after being bought on-line. Ticket inspectors will need to be equipped with bar-code readers, of course, but many are already sporting the technology and the standard has been devised in such a way that the last eight digits can be manually entered and checked on-line if necessary. Where a bar-code reader is used it shouldn't be necessary to perform an on-line verification as the 2D bar code contains authenticated details of the journey paid for.

The service does open up the opportunity to have one's phone poised, ready to buy a ticket should an inspector turn up, but you'll have to ensure you're are in the middle of a long carriage for that plan - as being dependent on timely SMS delivery to avoid a fine is not a good position to be in.

Improved Antenna to revolutionise mobile battery life

Atif Shamim, revolutionising mobile battery life

­Atif Shamim, an electronics PhD student at Carleton University, has built a prototype that extends the battery life of mobile phones, by getting rid of all the wires used to connect the electronic circuits with the antenna.

The invention involves a packaging technique to connect the antenna with the circuits via a wireless connection between a micro-antenna embedded within the circuits on the chip.

“This has not been tried before - that the circuits are connected to the antenna wirelessly. They’ve been connected through wires and a bunch of other components. That’s where the power gets lost,” Mr. Shamim said.

He estimates his module consumes 12 times less power than the traditional, wired-transmitter module. It is also much simpler in design, lowering the overall cost of any hand-held device, he said.

Mr. Shamim has filed patent applications in the U.S. and in Canada.

Earlier this year, the Ottawa Centre for Research and Innovation honoured Mr. Shamim and Mr. Arsalan as student researchers of the year for their work in the field of wireless biomedical sensors.

Shamim says his major goals for the innovation still lie in biomedical applications, including his original radiation sensors as well as remote healthcare sensors to monitor heart-rate, blood pressure and body temperature. He and Arsalan have also started up a company called Vital Signs Monitoring, and the two have already filed patents for the technology they developed. Clearly he has come a long way from when he first came to Canada, but he says his goals are still the same.

"My aim when I came here was to get some real skills in this domain, learn some new things and be an expert of something that would be valuable for me to find employment," said Shamim. "I was looking for a neat application for these small transmitters. ...That's where the trend is: make it cheaper, smaller, more efficient, so I think this is a good step towards that."

2008 saw an explosion in mobile social networking



Interesting article on Fierce Mobile Content on how Social Networking sites are being shaped by Mobiles and Vice-versa:

The volume of U.S. wireless subscribers who accessed social networks via mobile handset increased 182 percent between September 2007 and October 2008 according to a recent consumer study conducted by research firms The Kelsey Group and ConStat--in all, about 9.6 percent of U.S. subscribers ages 18 and over connected with a social network via mobile handset during the past year, compared to just 3.4 percent 12 months earlier.

A separate user study released this fall by market analysis firm ABI Research reports close to half of all social networking users have now visited destinations like MySpace and Facebook via mobile device. Forty-six percent of social network members have visited their favorite sites on their phones, with more than half of them checking for comments and messages from their friends--about 45 percent have also posted status updates. ABI adds that among all mobile social networking users, nearly 70 percent have visited MySpace, with another 67 percent checking their Facebook accounts. No other social networking destination achieved 15 percent mobile adoption. ABI suggests that consumers do not wish to create new and separate social networking profiles for the mobile platform, but instead prefer to access their existing social networking accounts on the go.

Both Facebook and MySpace enjoyed banner years in mobile. In November, Facebook announced its mobile userbase has expanded from 5 million to 15 million since the beginning of 2008--writing on The Facebook Blog, mobile team engineer Wayne Chang adds that in the 24 hours after the site began allowing subscribers to comment on their friends' status updates via the Facebook mobile site, users posted close to a million status comments. No less impressive, MySpace announced that same month that its integrated mobile solution customized for device maker Research In Motion's BlackBerry smartphones generated more than 400,000 downloads in its first seven days of release, an all-time high for both MySpace and RIM in terms of first-week downloads. Perhaps most important, the success of the BlackBerry MySpace app underscores social networking's growing profile among enterprise users--for many smartphone-toting professionals, 2008 was the year they abandoned their Rolodexes in favor of making and nurturing their contacts via the virtual world.

I can relate to this as mobile is now the main source of internet connectivity for my wife. I have been asked to get the new INQ1 phone from '3' as it would make her experience of Facebook better.
