Capacity optimization for 3G wireless networks

This paper evaluates code division multiple access evolution data optimized (CDMA2000 1x EV-DO) and the Universal Mobile Telecommunication System (UNITS) with regard to their ability to support simultaneous user equipment requests. The question of which of these third generation (3G) technologies is best was determined by analyzing their second generation (2G) core network technology scalability and extensibility and their ability to provide third generation cellular functionality. The core network (CN) architecture, which provides interconnectivity with fixed services such as the Internet and the public switched telephone network, serves as the platform for evolution to 3G performance. The performance results of a CDMA2000 1x EV-DO and a UNITS network were designed and analyzed using the Test Ericsson Mobile System (TEMS) CellPlanner simulation software. Simulation results were used to determine the accuracy of coverage predictions, the amount of traffic each system could support, and the number of simultaneous users that could be supported by each system.
