Wideband Code-Division Multiple Access atau biasa ditulis Wideband-CDMA atau W-CDMA merupakan teknologi generasi ketiga untuk GSM biasa disebut juga UMTS Universal Mobile Telecommunication System.

W-cdma. WCDMA dùng công nghệ DS- CDMA băng rộng để có tốc độ cao hơn và hỗ trợ nhiều người dùng hơn mạng 2G. Unlike second generation 2G CDMA mobile stations the W-CDMA UE can transmit more than one code channel in order to accommodate the high data rates. Both Frequency Division Duplex FDD and Time Division Duplex TDD variants are supported.

CDMA is a spread-spectrum multiple-access technique. Teknologi ini tidak kompatibel dengan CDMA2000 atau sering disebut juga dengan CDMA saja. When configured for W-CDMA 3GPP the instrument can be used for the testing of a W-CDMA transmitter manufactured according to the documents such as TS 25101 V310 TS 25141 V310 and so forth.

Wideband-CDMA or W-CDMA is a term used to denote the UMTS radio-interface for the paired bands UMTS FDD. A spread-spectrum technique spreads the bandwidth of the data uniformly for the same transmitted power. The W-CDMA protocol has a layered structure.

W-CDMA the radio technology of UMTS - is a part of the ITU IMT-2000 family of 3G Standards. CDMA has been used in the OmniTRACS satellite system for transportation logistics. The UMTS 3G mobile phone standard which uses W-CDMA.

W-CDMA occupies 5 MHz channels and has defined formats for elements such as synchronisation power control and the like CDMA technology. W-CDMA is a spread-spectrum modulation technique. What is W-CDMA Wideband Code Division Multiple Access.

3G UMTS relies on a scheme known as CDMA or code divison multiple access to enable multiple handsets or user. W-CDMA can be deployed in a number of bands see UMTS Bands. Wideband Code Division Multiple Access or W-CDMA is a wireless communication technology derived from Code Division Multiple Access CDMA cellular phone technology that is proposed for 3G.

The HLR is an integral component of CDMA code division multiple access TDMA time division multiple access and GSM Global System for Mobile communications networks. One which uses channels whose bandwidth is much greater than that of the data to be transferred. The W-CDMA JLA is the most efficient and cost controlled way for manufacturers and distributors of products implementing the W-CDMA standard to license patents that are essential to the use of the standard.

The first Multiple Access Third Generation Partnership Project 3GPP Wideband Code Division networks WCDMA were launched in 2002. Efforts to develop a global standard for providing high-speed high quality multimedia services have crystallised in the form of the third generation 3G systems under the IMT 200 standard. 18 rows W-CDMA Protocol Structure.

The W-CDMA Licensors consist of a seminal group of companies that helped pave the way for the development implementation and near ubiquitous adoption of the 3G cellular standard. The core bands for deployment of UMTS FDD Wideband-CDMA are. The W-CDMA specifications use the term user equipment UE to refer to mobile phones wireless computer devices or other devices that provide wireless access to the W-CDMA system.

The evolution of cellular based mobile communication systems from the first generation analogue to the second generation digital has been made possible by solving many technical issues along the way. Home Location Register HLR. MeasSetup W-CDMA3GPPHSPA Demod Properties ChannelLayer tab.

W-CDMA sau WCDMA sau Wideband CDMA este un standard de telecomunicație prin unde radio folosit în rețelele de telecomunicație telefonie mobilă de tip GSM - 3G. Steps in CDMA modulation. Wideband Code Division Multiple Access WCDMA is a third-generation 3G standard.

At the end of 2005 there were 100 WCDMA networks open and a total of more than 150 operators with licenses for frequencies WCDMA operation. W-CDMA viết tắt của Wideband Code Division Multiple Access trong tiếng Anh. Maintained by the subscribers.
