W-CDMA

Wideband Code-Division Multiple Access or Wideband-CDMA usually written or W-CDMA, is third generation technology (3G) to GSM, also called UMTS (Universal Mobile Telecommunication System). This technology is not compatible with CDMA2000 or often known as CDMA only.

WCDMA speed may reach 384 kbps and the future will rise to probably around 10Mbps.

This technology uses the AMR-Wideband (Adaptive Multi-rate) for the codification of sound (voice codec) so that the sound quality got better than the previous generation.
