Quite right. It was developed by ETSI, where E stands for European. It's a brilliant implementation of mediocre TDMA technology. Putting the phone's identity in the SIM wasn't a new idea but they made it work. >I have no idea why you would state it's superior.

That has everything to do with frequencies. AT&T (GSM) and Verizon (CDMA) are mostly at 800MHz, while T-Mo (GSM) and Sprint (CDMA) are at 1900 MHz. The 800 MHz carriers have much better coverage because 800 propagates better than 1900. I have switched back and forth between AT&T and Verizon (Tracfone resells both so you can switch phones without losing your minutes) and AT&T works better here for the sole reason that the tower is closer and higher up. --- SoupGate/W32 v1.03 * Origin: LiveWire BBS -=*=- UseNet FTN Gateway (1:2320/1) |
