Let's count: AMPS/NAMPS US TDMA (1900Mhz? 900Mhz?) US CDMA (1900Mhz? 900Mhz?) US GSM (1900Mhz) European GSM (900Mhz/1800Mhz) To which you will be able to add W-CDMA, with the advent of the 3G networks. Of course, this doesn't begin to address the needs for analog coverage outside the US -- this is just a list of the different technologies and frequencies of which I am personally acquainted. I'd love to see this list get expanded. > The real issue is competition. One large company would be able to get > better coverage. Coverage is extremely expensive to build. It's much cheaper to buy. And even then, you don't really try to dot the entire country side with a tower in each and every square mile (maybe every 1/10th of a square mile in cities), you just don't bother trying to put up antennas in the less populated areas, and you live with the fact that 98% coverage is good enough and the rest of the people can just piss off. >> Love love 3G+W-CDMA. > > And where do I get one?
