: --------------------- : Ok, the question then would be what is going to be made available in the : interum for the alledged high speed data services. And also how can they : expect this system to work to its full potential as the current CDMA system : does in the farming/remote/non metro areas?? Sounds like a typical : government/telstra FU here, I seem to remember them saying GSM would within : a few years have the coverage analogue did but this never happened. : :
only time will prove, that in the end, this scheme actually worked. I say it won't, and if your benchmark is: the same coverage as AMPS as well as high speed data. then we already know the answer?
