TGV tests Wi-Fi + satellite link in three TGV trains on its Eastern network. If the experiment proves successful the new service should be generalized, from 2009, to all 52 oars network East.

With combines effort of satellite link and wireless network, in locations, such tunnels and train stations, where the satellite link cannot be established, the wi-fi network takes over to maintain the access to the Web without interruption.

French railways company SNCF previously conducted unsuccessful test using GPRS data network before launching a 2 years research and preparation program to implement this dual solution. Among technical difficulties to overcome are these related to 320 km/h TGV trains speed which causes instability and vibrations. 

The project is done in a partnership with Orange(France Telecom mobile operator), Capgemini, Alstom Transport and Eutelsat.

SNCF will put on board of its TGV a dedicated Web portal providing information about destinations, weather forecast, News, traffic information as well as a real time tracking service. From a technical point of view, TGV trains are fitted with a server where all portal content is loaded prior the journey in order to minimize bandwidth consumption due to its high cost. The tested system has been designed to provide simultaneous web connection for 14 per cent (50 users) of the total capacity of each TGV train (350).

The business plan is not defined yet, but the widespread of the system on TGV Eastern Europe network would represent an investment of 120 millions USD over 4 years. First price estimation given by SNCF Passenger service would be a flat 4-5 USD to access the Web portal during the whole journey and a 4-5 USD per hour to access the Internet.

A very interesting project and definitively a real challenge to maintain permanent web connectivity during a train journey at more than 300 km/h where the 16'000 volt power line running over the train may also create some electro-magnetic interferences and without mentioning all micro interruptions of the satellite link each time the train pass under a bridge or when dense foliage is found within the satellite's line of sight.

Any reader who already had the chance to test the reliability of the service ?

Just finished to watch Hugo Ortega's video presenting HTC Shift and I must admit I like the HTC idea of bringing to us an UMPC (Ultra-mobile computer) which has 2 processors and 2 operating systems working independently on board.

Is the UMPC form factor market ready to take-off soon ?
Is the double O/S option chosen by HTC the winning one ?

A recent research by In-Stat found the following:

• The UMD worldwide forecast is for more than 8 million units in 2011.
• 2008-2010 will be key years for the development of a market inflection point of anytime/anywhere wireless connectivity that is necessary for widespread adoption of the UMD paradigm.

Some specifications: 

• Size: 19 x 13.5 x 3cm
• Weight: 0.9 kg 0.791 kg
• 7 inches display
• Resolution : 800×480 - 1024×600
• Operating Systems : Windows Mobile 6 & Windows Vista Business
• CPU's : Qualcomm 400 MHz for WM6 & Dual Core 800 MHz Intel A110 for Vista
• 7 days battery capacity running on WM6 only. 3 hours on Windows Vista
• Ram Memory : 1 GB
• Hard Drive : 40 GB
• Communication : WiFi 802.11 b/g, Bluetooth 2.0,
• Phone data : Quad band GSM/GPRS/EDGE - Tri-Band UMTS/HSPDA
• 1.3 MB built-in camera
• 1 USB 2.0 port, 1 VGA port
• 1 Finger print reader
• 1 SD Card reader
• Slide out Tilt display
• Price tag : 1200 euros (?)
• Availability : Q3 2007

The very interesting concept is the possibility to switch from one environment (e.g WM6) to the second one (Vista Business) and back in just the press of a button. Input can be done either using the QWERTY keyboard or the hand-witting recognition system.

Shift on HTC website  

Well known for its analysis, the Gartner Group predicts, in its last week press release, that Instant Messaging systems will be the "de facto" tool for voice, video and text chat with 95% of workers in leading global organizations. It may even become the primary interface for real-time communications by 2013. The Gartner Group forecasts the IM market to grow from 267 mio/USD in 2005 to 688 mio/USD in 2010.

As part of the corporate IT infrastructure, they recommend use of corporate IM solutions such IBM "Lotus Sametime" or Microsoft's "Office Live Communication Server" as they can be protected by the corporate firewall. One key part of IM corporate setup will be the "Presence Technology" which allows people to establish the availability of others for real-time communications regardless of their location.  It also enables users to cut through desktop clutter, resulting in immediate responses.

As a result, Gartner predicts that by 2012, presence technology will be offered independently of IM and email products.  Mr David Mario Smith, research analyst at Gartner, urged vendors and enterprises alike to recognize this and develop a real-time architecture with presence as the key ingredient. “The IM client is becoming the launch pad for many types of communications channels and services,” he concluded.  “Presence will extend its influence beyond IM to become an essential source of innovation for enterprise applications of the future.” 

This release collides with a discussion I had last week with some colleagues about which IM tool we were using and which one is our preferred. Personally, a tool like Skype makes my day as I get to use it to transmit and receive messages from many networks and not exclusively from the Web. However, it is well known that Skype is a real nightmare for corporate ICT Security officer and this piece of software always tries its best to find a way to connect the net, bypassing any corporate security (firewall & NAT) using peer-to-peer technology.
