TL;DRAbstract
Coverage and capacity planning of WCDMA-based UMTS cellular networks are strongly tied together. This chapter introduces the principles of the UMTS topology planning, which means combined coverage and capacity planning. The topology planning phase contains definitions of site locations and configurations together with the base station antenna configuration. These technical elements influence the network coverage and system capacity of a UMTS network. Critical coverage and capacity topics such as signaling channel power needs, multiple services, Erlang-B capacity, and load equations are first introduced separately as they relate to the initial topology planning phase. Finally, radio network system simulations of actual topology planning are described and the impact of different base station site configurations on system coverage and capacity are presented with examples.
