ConclusionConclusion

In the near term, GSM/GPRS with the introduction of AMR andEGPRS offers sufficient performance.

UTRA/WCDMA is the most efficient of all the 3G technologies.WCDMA and CDMA2000 use the same underlying spread-spectrum technologies, but the wider bandwidth of WCDMAwill always mean that there are inherent advantages for WCDMAover CDMA2000.

Interoperability between GSM & UMTS and CDMA 2000 still open.USIM/UICC provides a first step.

There are 107 UMTS network rollouts on their way using new 3Gspectrum, offering high traffic capacity.
