This chapter presents coverage and capacity results and investigates the impact of the radio propagation environment, advanced base station (Node B) solutions, and WCDMA physical layer parameters. The advanced base station solutions include both baseband and antenna techniques. Cell coverage is especially important in terms of the initial network deployment investment, where the offered traffic load does not set demands for a fine grid of cells. The chapter analyses WCDMA network coverage. The importance of capacity will increase after the initial coverage deployment when the amount of traffic increases; WCDMA capacity is presented. The chapter, also presents the WCDMA air interface capacity, which is limited by interference. It presents the results from field capacity trials. The chapter analyses the 3GPP performance requirements and presents the possible performance enhancements that are supported by the 3GPP standard, including adaptive antenna structures and multiuser detection with advanced baseband processing. Controlled Vocabulary Terms base stations; multiaccess communication; multiuser detection
