WCDMA

Wideband code division multiple access (WCDMA) is a CDMA channel that is four times wider than the current channels that are typically used in 2G networks in North America.

In January 1998, European Telecommunications Standards Institute (ETSI) decided to choose the W–CDMA technology to be the multiple access techniques for the third-generation mobile telephone system. For a mobile communication system, a key parameter is the system capacity. A number of methods to increase system capacity in a W–CDMA network are discussed. This tutorial presents results from different antenna pattern parameters and sectorization techniques for optimizing the maximum number of active subscribers

WCDMA is a wideband digital radio communications technology, which provides new service capabilities, increased network capacity and reduced cost for voice and data services compared to 2G technologies. It provides simultaneous support for a wide range of services with different characteristics on a common 5 MHz carrier.

WCDMA, one of ITU's IMT-2000 standards, is the leading global 3G standard selected by 8 of the world's 10 largest operators. Operators can smoothly evolve from GSM to WCDMA, protecting investments by re-using the GSM core network and 2G/2.5G services.
