WCDMA (UMTS) Deployment Handbook Planning and

After introducing the network architecture of such a system, the WCDMA (UMTS) Deployment Handbook defines the coverage and capacity concepts associated with the dimensioning and design phases. It then progresses to a discussion of the main system parameters associated with network optimization and details optimization techniques for the main services supported by UMTS.

Christophe Chevallier is Senior Staff Engineer at QUALCOMM Inc. He is a radio frequency engineer with over 10 years’ experience in telecommunications, mainly in CDMA technologies. Christophe has proven experience in the field, optimizing cdma0ne (IS95) network, planning and optimizing WCDMA network and supporting CDMA2000 deployment.
