Full Form of WCDMA | WCDMA Full Form | What is WCDMA

Full Form of WCDMA is Wideband Code Division Multiple Access: WCDMA may be a broadband spread-spectrum 3G mobile telecommunication air interface that utilizes code division multiple access (or CDMA the final multiplexing theme, to not be confused with CDMA the standard). It provides simultaneous support for a large vary of services with totally different characteristics on a typical 5MHz carrier.

The term WCDMA conjointly refers to 1 of the International Telecommunications Union’s IMT-2000 standards, a sort of 3G cellular network. WCDMA is that the technology behind the 3G UMTS normal and is closely allied with the 2G GSM commonplace. It provides new service capabilities, enlarged network capability and reduced price for voice and information services.

The term WCDMA Evolved’ describes the evolution of WCDMA, addressing each operators’ wants for potency and users’ demands for increased expertise and convenience. The primary steps of this evolution are HSDPA and increased transmission.

W-CDMA uses the DS-CDMA channel access technique with a combine of five megahertz wide channels. In distinction, the competitiveCDMA2000 system uses one or additional offered 1.25 megahertz channels for every direction of communication. W-CDMA systems are wide criticized for his or her massive spectrum usage, that delayed preparation in countries that acted comparatively slowly in allocating new frequencies specifically for 3G services (such because the United States).

W-CDMA is that the basis of Japan’s NTT DoCoMo’s FOMA service and therefore the most-commonly used member of the Universal Mobile Telecommunications System (UMTS) family and typically used as a word for UMTS. It uses the DS-CDMA channel access technique and therefore the FDD duplexing technique to attain higher speeds and support additional users compared to most antecedently used time division multiple access (TDMA) and time division duplex (TDD) schemes.

While not an biological process upgrade on the airside, it uses a similar core network because the 2G GSM networks deployed worldwide, permitting twin mode mobile operation together with GSM/EDGE; a feature it shares with different members of the UMTS family.
