thanks bux. disregard my other post. we're alittle out of sync.
was hoping tdma would become extinct. this does not put any pressure on att to switch from tdma.
also does this mean gsm is not evolving to wcdma

Bux,

DECT uses time division multiple access (TDMA) to transmit radio signals to phones.

DECT also uses frequency hopping to avoid interference. It is widely used for cordless phones in Europe. I have one with one base unit and three handsets. Excellent sound quality. I have tried deliberately jamming it with a microwave sweep oscillator and it just hops around the interference. Range up to 300m free space. It also uses polarisation diversity with two orthogonal diode switched antennas in the base unit. However, it is not suitable for wide area use, as you say.
