Publisher Summary This chapter discusses the wideband-code division multiple access (W-CDMA) network planning to develop and execute the procedures required for attaining a workable plan. W-CDMA planning consists of the development and establishment of the planning process and the network optimization procedures, followed by the development of the actual network design plan. Capacity, coverage, and quality are the three factors that give a better understanding of the proposed requirement. Within a third-generation network, the planning and optimization/re-planning tasks will become an ongoing process. The main objective of network planning is to efficiently control and maximize the effects of these parameters. Preparation, number of estimated cells, and management of the network plan are the three phases for achieving an accurate network plan. Network design planning must consider microcell/macrocell coverage and capacity, indoor and high data coverage, co-location, and migration from global system for mobile communication network. Network optimization requires proper analysis of network performances.
