WCDMA - Wideband Code Division Multiple Access
A technology for wideband digital radio communications of Internet, multimedia, video and other capacity-demanding applications.
WCDMA is the dominating 3G technology, providing higher capacity for voice and data and higher data rates. WCDMA uses a new spectrum with a 5 MHz carrier, providing 50 times higher data rate than in present GSM networks (and 10 times higher data rate than in GPRS networks) WCDMA handles up to 2 Mbps for local area access or 384 Kbps for wide area access. A coming release will include enhancements up to more than 10 Mbps.
WCDMA is also known as UMTS and has been adopted as a standard by the ITU under the name IMT-2000 direct spread.
The gradual evolution from today's systems is driven by demand for capacity, which is required by new and faster data based mobile services. WCDMA enables better use of available spectrum and more cost-efficient network solutions. The operator can gradually evolve from GSM to WCDMA, protecting investments by re-using the GSM core network and 2G/2.5G services.
