The WNDW team has released its second edition of the book "Wireless Networking in the Developing World". The 425 page book includes lots of new material, including new chapters on solar power and economic planning, several new case studies.

The book is released for free under a Creative Commons license and is available in several languages (including Spanish, French, Italian, and soon Arabic and Portuguese). and it is free to download, print, update, or redistribute it.

The Wireless Networking in the Developing World book is just one part of the WNDW project. Community forums, training workshops, and additional material are also available on their website, http://wndw.net/.

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 ?

I found the article below on "The Register" site and asked myself the following question: 

If connecting to Internet using an open and unsecured wifi access point is considered as a crime, why authorities do not apply the same principle to other services (mainly electricity and water) we often use without any formal agreement of the owner ?

 " More than half of computer users have illegally stolen Wi-Fi connections, according to The Times - but only 11 alleged offenders have been arrested in the UK, as the police seem to think those deploying Wi-Fi should be more careful about securing their connections.

The data was collected from a "Have Your Say" survey on the website of security-specialist Sophos: apparently 54 per cent of the 560 people who responded admitted nicking bandwidth from insecure Wi-Fi routers.

This might say more about Sophos customers than the general population, and extrapolating the results to every computer user in the country is probably a crime against statistics: so that's exactly what The Times has done.

…

Anyone caught stealing a Wi-Fi connection can be fined up to a grand, even if it's left unsecured, so make sure you ask nicely next time you're looking to log on, and if the person next to you has never stolen a Wi-Fi connection then we have to assume that you have. "

What is your opinion about accessing open wifi ? Do you think it is a crime ?
