ELP 0606 ★★★
The course presents an overview on the architecture, functionality and services of UMTS. The focus is put on the new, characteristic features of UMTS/WCDMA differentiating the system from GSM. The course provides a detailed survey through WCDMA air interface including spreading operation, fast power control, soft handover, rake receiver as well as some aspects of radio network planning. It describes the UMTS Terrestrial Radio Access Network as well as the Core Network elements and functions. A brief introduction to protocols and procedures in UMTS is given. The course provides the participants with the overview on UMTS service concepts as well as presents some major security issues in UMTS.
The course is based on the 3GPP Technical Specifications and hence is vendor-independent.
Target audience – Who should attend and benefit
The course is addressed to network engineers and consultants who will work with UMTS system, as well as any technical staff requiring deeper appreciation of UMTS.
