Been reading a little about how the nice people at RailEurope implemented WiFi on the Thalis. Have not been able to get too much information other than what is avaliable on the pamphlet and their website. I will try to post more about this, some really innovative stuff. Satellites tied in with ground celluar based tranceivers for when the train is travelling through a tunnel. Apparently this is a consortium of companies from many countries including the Finnish Nokia, Siemens and others.
