Introduction:

WCDMA (Wideband Code Division Multiple Access) is the radio access scheme used for third generation cellular systems that are being rolled out in various parts of the globe. The 3G systems to support wideband services like high-speed Internet access, video and high quality image transmission with the same quality as the fixed networks. In WCDMA systems the CDMA air interface is combined with GSM based networks. The WCDMA standard was evolved through the Third Generation Partnership Project (3GPP) which aims to ensure interoperability between different 3G networks. This course provides an overview of the WCDMA system, as defined in the 3GPP Release 99 specifications for the Universal Mobile Telecommunications System (UMTS). The course begins with an overview of WCDMA and UMTS concepts, including spectrum allocations, network topology, protocol stack, and channel mappings. It then describes the procedures of the Access Stratum protocol layers, covering the Radio Resource Control, Radio Link Control, and Medium Access Control layers. Next, physical layer transmit procedures are covered, as well as procedures for acquisition, random access, paging, measurements, power control, and transmit diversity. The course concludes with discussion of handover and cell reselection procedures, security features, and call setup procedures for packet-switched and circuit-switched calls.

Audience:

This course is for the experienced telecommunications professional with a need to learn the principals of WCDMA.

Prerequisites:

Technical background in wireless telecommunications

Customize it:

This 2-3-day WCDMA course will be customized to your needs and specifications. Enowireless will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Enowireless, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.
