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

The standards are not designed to pressure operators to upgrade to a more cost effective solution, that is what competition is for. Formerly, CDMA was not allowed on European spectrum in order to compete.

If wireless voice and data use continues to grow as it has been, it will become increasingly sensible for European operators to deploy a CDMA solution. The demand for fast data will require an upgrade to some form of 3G. The proposed 3G solutions (including DECT and GPRS) are not compatible with current handsets. It is my belief that when the newer 3G networks (that are not compatible with current subscriber devices) are deployed, they will be CDMA for reasons of total cost, ease of deployment, ease of adding additional capacity, performance of soft-hand-off, resistance to multi-path interference and capacity benefits. Not because the standards bodies mandate it.

GSM is well entrenched and I would not hope for a fast and complete change of technology. That would be too disruptive. More likely is a gradual replacement of some frequencies with CDMA or the deployment of CDMA in unused spectrum. The market will drive the choice. While Europe is a big market, I would look towards other markets for near-term CDMA growth.
