Soon using GPRS or 3G connections on trains will be a thing of the past. On the train, users can now connect via standard 802.11b Wi-Fi and using onboard equipment, a conversion to 802.16d is made. The system does not need to wait until 802.16e is available, so the implementation can be started earlier. Currently the service is free to use but from June T-Mobile will start charging users. I'm sure a lot of people will use this service as it'll mean real broadband speeds are available on trains instead of limited more by using 3G and GPRS.
As all of the base stations along the track are not yet in place, the system switches users over to GPRS when there is no Wi-Fi signal, of course the user may notice the slower speeds but at least the conection will be maintained. I'm sure it won't be long before we'll be playing online games on our PSP consoles over Wi-Fi.Post ID: 733, posted by jase at 10:59 PM
