What part of "WCDMA" do you not understand? GSM is a TDMA technology. WCDMA is a CDMA technology. LTE, at least what we expect, will be an OFDM technology.
EDGE is an evolution of GSM.
WCDMA HSDPA is an evolution of WCDMA UMTS.
But between those levels there's a hard break in technologies - you have to install all new radios and there's a different IP portfolio you have to deal with. Qualcomm owns about 20% of the WCDMA patents, for instance.
