IPWireless eurostars in Speed 3
For the moment, IPWireless' trial with "a leading European GSM operator" worked "up to 220 kilometers per hours in a series of recent road and rail demonstrations" but the vendor "expects that the solution will support speeds of more than 400 kilometers per hour". UMTS RailLink combines TDD (TD-CDMA) with WiFi.
Good news for France, whose TGV is already connected to 3 of the other Top 5 telecom markets (UK, Germany and Spain - Italy being the weaker link and UK the most demanding because of the Chunnel - plus such countries as Belgium or the Netherlands). SFR and SNCF have been partners for years but IPWireless already works with Orange or T-Mobile and this is not the kind of trials you do first for TDD.
Besides, 220 km/h happens to be the maximal speed of the French bullet train on conventional lines (over 300 on hi-speed lines) : the trials must have been run outside of France, for example between the Chunnel and London (IPW mentioned a 39 km section and bridge sections).
Whatever. IPWireless seems on the right track.
More on IPW in TDD & TDMB : not so TDous, Livedoor to incumbents : you've got mail (NB : no doubt the Japanese will have a close look at this bullet train experiment) or Tadaa, TDD data updated.
