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.

Femtocell interference by macro network is now addressed

It is widely accepted that the deployment of femtocells will be a significant factor in driving the future uptake of mobile broadband services. There has been concern however over potential issues of interference between femtocells and the micro/macro networks. These concerns have been largely allayed by a femtocell radio study carried out by The Femto Forum.

If one understand the basic concept of femtocells that the concern for interference is obvious. The femtocells and macrocell network share the same carrier and hence the cause for interference. The simplest way to avoid interference is for the femtocell to utilise a different carrier than the surrounding macro network. But I think this will be like running away from the problem instead of solving it. Also this not very much feasible or practical solution either because majority of 3G operators do not have sufficient spectrum.

This issue was really serious and as expected whoever involved with the femtocell deployment specially the Femto Forum got involved into the research to answers the queries regarding the interference.

The Femto Forum study therefore focused on finding technological solutions for mitigating interference when both the femtocell and macrocell networks share the same carrier. These methods are already being developed for pre-standard femtocell solutions, and Femto Forum members are working to bring them within the standards framework.
The main objective of the study was to identify a number of solutions that will mitigate any potential interference of the macro network by the femtocells.

The first really good news is that the study found femtocells have the potential to deliver an order of magnitude of more capacity than the macro network alone when used in dense deployments, even when occupying the same radio channel as the macrocell.

Effectively what it’s been suggested is that any interference related barriers to wide scale femtocell deployment have been removed so operators will be able to maximise the capacity benefits offered by femtocells.

Following are the key solutions suggested for interference mitigation considering that femtocell and macro cell using the same carrier:

• Adaptive Pilot Power Control: In this case the femtocell dynamicallyadjusts its transmit power in response to the current level of signals fromsurrounding cells and the desired coverage area.
• Extended Tests for Dynamic Range: This will ensure that femtocell designsare able to operate reliably even in the presence of nearby high powermobile phones connected to the macro network (this test has already beenincorporated into the latest 3GPP Release 8, 25.104 specification).
• Uplink power capping: This technique specify that the uplink power of the mobile phone is capped when operating in the femtocell environment thus ensuring that even in difficult radio conditions,the phone hands-off to the macro network before its transmit power increasesto the point where macro noise rise is a problem.
• Dynamic receiver gain management: Automatic gain or adaptive attenuation in the femtocell will ensure that femtocells can offer good service to both near and far mobile phones without unnecessarily increasing the phone transmit power, therefore keeping the noise rise to a minimum.

At a time when mobile operators are seeing data usage rocket, femtocells offer an economic and effective way to deal with demand. This therefore makes it very important for the femtocell technology to sort out any niggling issues.

There is no doubt that by utilizing the identified interference management techniques femtocells can offer operators an effective method to increase capacity and coverage within theirexisting networks through dense cell deployments.

Marketting is the key for femtocells success

In the last year alone femtocells has come a long way and as we speak the technology is in the process of getting deployed at many places. There is no doubt that mobile operators have moved from laboratory tests and technical trials to large-scale commercial pilots of femtocells. The most public of these has been Softbank Mobile in Japan that is using around 10,000 femtocells to test the technical and commercial feasibility of the technology.

There are so many multinational operators who are conducting trials as above with the objective of launching commercial pilots during Q1/2009.

However this opportunity is reliant upon mobile operators developing and marketing a proposition that will have obvious appeal to the consumer.

Even now in some countries the mobile operators struggle to understand what femtocell proposition will work in their market? They understand the business case, but the key issue of how to persuade a customer to acquire and install a femtocell remains unsolved in many regions.
This could be explained best by taking the example of Germany where cellphone subscribers are accustomed to using advantageous 'home-zone' tariffs that use the normal cellular network to determine when the subscriber is making calls from their home. Attempting to undermine this attractive proposition with a femtocell-based solution could be difficult. However places where comprehensive 3G coverage is compromised it is possibly providing the subscriber with their own femtocell, or personal 'home cell which could eventually prove to be particularly attractive for the customer.

I believe the key challenge is the consumer proposition and the future success depends on mobile operators and their ability to package their femtocell propositions appropriately for the various market segments.

I always ask the question whether standalone femtocells are likely to be short-lived.
ip.access claims it is already seeing demand for femtocell modules to be integrated into other devices, such as WiFi home hubs and set-top boxes, etc.

Moving aggresively into the direction of making the femtocell technology a real success, major global operators are now backing the vision of taking femtocells out of homes and offices into the wider environment as part of their Long Term Evolution (LTE) deployment. I think this is a smart move as you cannot be relying completely on the “home only” concept to move femtocells in the vicinity of huge success. At the LTE World Summit in London, China Mobile, T-Mobile and Telus all expressed support for this idea that first was advanced by Vodafone earlier this year. Femtocell specialist picoChip gave reality to this concept by announcing further details of what is claimed to be the industry's first complete LTE picocell and femtocell reference designs. These new platforms will enable high capacity networks for metro, hot-zone and rural deployments. According to the picoChip view of LTE, all deployments will consist of small femtocell base stations.

I hope you agree that with femtocell technology reaching commercial maturity, attention is now switching to developing application services and operator business models that will maximize the technology benefits which will eventually lead to a success story for femtocells.

India gets ready for 3G

So here comes 3G in India. It’s been long coming as the data needs were increasing rapidly in almost all the Indian states. With the existing cellular infrastructure not capable of holding huge traffic particular for data, arrival of 3G was imminent.

The Indian Department of Telecoms (DoT) has published its official timetable for the award of its 3G licences across the country as well as a breakdown of how the relevant spectrum will be allocated across the telecoms circles.

As expected, the state-owned operators BSNL and MTNL each have been reserved one block of 2x5MHz in each circle, with the exception of Rajasthan (State in North West India) which will have no 3G spectrum at all. The number of blocks of spectrum in the private auction differs depending on the circle (see the spectrum table, below).

The auction for the 15-year licences is planned for Jan. 15, 2009. In the majority of 3G service areas there is 25 MHz of paired frequency bandwidth available which relates to four blocks of 2x5 MHz spectrum available for auction in addition to the block reserved for the state-owned operators, Bharat Sanchar Nigam (BSNL) and Mahanagar Telephone Nigam (MTNL). Spectrum is rather limited in many other areas, including the major metro circle of Delhi where only two 2x5MHz blocks will be available to private operators.

All of the 3G spectrum will be in the 2.1 GHz band and in the 2.3 GHz and 2.5 GHz frequency bands, a separate auction for Broadband Wireless Access (WiMAX). In both these auctions, which will take place two days after the 3G auction, bidders are restricted to just one block of spectrum per service area.

The table below shows the proposed spectrum layout.

Service Area (Indian Cities or States)	Paired frequency bandwidth to be allotted	Paired frequency bandwidth to be allotted
Delhi	160	15
Mumbai	160	25
Kolkata	80	25
Maharashtra	160	25
Gujrat	160	15

Texting and Internet being trialled on flights

BMI is piloting mobile internet and texting services on planes, but frequent flyers need not get up in arms about getting stuck next to chatty people, as the airline has wisely chosen to leave out voice calls.

The service, from OnAir, will be trialled for six months on just one plane – an Airbus A320, which flies between Heathrow and Moscow. Passengers will be able to use SMS, email and internet on mobiles, PDAs and laptops with GSM SIM cards or dongles.

Peter Spencer, managing director of BMI, said: “It opens up an exciting new era of travellers being able to stay in touch by text message and email whilst in the air.

The pilot project isn’t just about testing the tech or the take-up, however. “The trial will help us address some of the social and etiquette issues regarding the use of mobile communications devices inflight and provide valuable customer feedback which will be at the heart of deciding how the service is developed and rolled out across the remainder of our mid haul fleet,” Spencer said.

“We have chosen not to implement the voice call option as part of the trial,” he added.

On the other side of the world, Delta Air Lines officially launched Aircell's Gogo Inflight Internet service on six of its aircrafts. In-flight Internet initially will be available on five MD-88 aircraft flying Delta Shuttle routes between New York's LaGuardia Airport and Boston's Logan and Washington's Reagan airports plus one Boeing 757 flying throughout Delta's domestic system, with service spreading to other Delta routes as additional aircraft are introduced.

"In-flight Internet access is one of the most popular requests we receive from our customers," noted Tim Mapes, Delta's senior vice president of marketing. To celebrate the launch, Delta passengers traveling on the Gogo-equipped MD-88 Shuttle aircraft will be treated to a holiday surprise with complimentary access to Gogo during a Dec. 16 - 31, 2008 promotional period.

A "WiFi hotspot" decal will be prominently displayed adjacent to the boarding door of the MD-88 aircraft so customers will know Gogo Inflight Internet service is available on their flight. In addition, a Delta-Gogo instructional card will be available in each seatback, providing details on how to sign up for the service. Gogo representatives and Delta employees will be available at all three Delta Shuttle-served airports throughout the promotional period to provide information and assistance to customers traveling during this timeframe.

Mobile healthcare named 2009 tech pioneer

The World Economic Forum on Thursday named Japan-based Mobile Healthcare Inc (MHC) as a 2009 Technology Pioneer. The company, which develops real-time mobile health solutions for preventing and managing diabetes, obesity and other lifestyle-related illnesses that can be accessed over mobile phones, became one of the 34 technology visionaries to be honored at the 2009 World Economic Forum.

MHC Founder & CEO James Nakagawa said, “We have aspired from the outset to be pioneers, exploring the life-changing potential of mobile technology and finding solutions that empower people to tackle their own health issues affordably and easily via their personal cellular devices and the Internet. I was at once ecstatic and humbled by the news that our work had gained disciples from amongst the venerable body of global business and financial leaders put forth by the World Economic Forum.”

The company’s flagship product, Lifewatcher, is a mobile phone-based health management application for people with so-called ‘lifestyle diseases’ such as diabetes and obesity. Users can monitor their own conditions by logging blood sugar levels, calorie intake, exercise and many other variables into their ‘always on’ mobile device, creating a one-glance health portfolio, which collates daily, monthly and even yearly data. It also delivers vital medical information, reminders and alerts with escalating alarm-levels if goals are not met.Using real-time cellular technology, diabetics and lifestyle illness sufferers can also be in constant dialogue with medical practitioners to ensure health measures are in check or, if not, to spark intervention that could save lives. With the dramatic rise of diabetes and obesity to pandemic levels in countries like Japan and the U.S., doctors have been welcoming this self-directed management tool that affordably and easily increases drug, nutrition, exercise and monitoring compliance for sufferers.

Motohisa Furukawa, a high-ranking Japanese politician and long-time participant at Davos said: “Japan is particularly proud this year to see Mobile Healthcare accepting this honor. It is my hope that government representatives attending Davos this year will recognize the particular relevance of innovative technologies like Lifewatcher, as a universal low-cost healthcare solution that is also environmentally sustainable, as we move forward in these tough economic times in a resource-constrained world.”

Nokia may be entering laptop market

With the telecoms market so tight every company especially the giants like Nokia are looking at the alternatives for their revenues to go further north. Some time ago there was a rumour that the Nokia might enter into the laptop market and hence widen its area of business. Although at that time this was categorically denied by Nokia, rumours the Finnish mobile giant may be planning to enter the laptop computer market have resurfaced. On this occasion it was through the medium of a research note from a Union Bank of Switzerland (UBS) analyst. For a report that could just be speculative it contained a remarkable amount of detail suggesting as it did that the Nokia device would be a 9 to 10 inch notebook/tablet computer with touchpad, NFC and Linux OS.

In its early days Nokia did produce computers but by the mid-1980s it had exited the business, merging its PC division with Ericsson Information Systems.

In the past of couple of years we have seen that companies like HP and Apple have moved into the smartphone business and hence taken a small share of the market. This has really affected likes of Nokia, Ericsson, Samsung and other vendors. Taking a leaf out of computer manufacturers such as HP and Apple who has moved into smartphone business, Nokia thinks that perhaps it is its time now to mount a counterattack.

Indian m-Commerce service among top tech pioneers for 2009

JiGrahak is behind ngpay, the brand name of a free mobile-commerce service that allows consumers in India to shop, order meals, make charitable donations, do their banking, and pay their bills, among other things. Launched last February, ngpay already has attracted more than 230,000 users and has become the largest channel for mobile-based transactions with Indian Railways and HDFC Bank, and for movie ticketing. The company expects to have 1 million users by mid-2009.
