Conclusion In the near term, GSM/GPRS with the introduction of AMR and EGPRS offers sufficient performance. UTRA/WCDMA is the most efficient of all the 3G technologies. WCDMA and CDMA2000 use the same underlying spreadspectrum technologies, but the wider bandwidth of WCDMA will always mean that there are inherent advantages for WCDMA over 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 3G spectrum, offering high traffic capacity.
