All mainstream 3G networks today are based on CDMA system and have limited capacity. The specific parameters when the load of a cell is saturated depend upon various services
and wireless network needs capacity expansion to meet the demand of growth of hybrid multi-services. This paper analyzes the 3G multi-service capacity
discusses about the growth forecast of 3G services
the capacity features of 3G system
3G multi-service modeling and analyzing methods
gives solutions to the capacity expansion of wireless network
and elaborates on addition of carriers and the BBU+RRU in indoor coverage solutions
and can provide some reference for the capacity expansion of 3G wireless network.
