CDMA network deployment of 8 kbps and 13 kbps voice services
J. Ketchum, M. Wallace, Rod Walton · Proceedings of ICUPC - 5th International Conference on Universal Personal Communications · 2002
Network deployment of voice services based on IS-95 CDMA using both 8 kbps and 13 kbps service options are explored from the standpoint of capacity and coverage. Specifically, issues regarding the various performance tradeoffs associated with operation at 8 kbps and 13 kbps are examined. Significant differences in the system performance exist between these service options, particularly on the forward link. System processing gain, E/sub b//N/sub t/ link performance, forward link power control, along with voice activity and Erlang variations, all contribute to system performance differences. The impact of these and other deployment-related variables on the delivered end-to-end quality of voice services in a large network are addressed. The functionality of a CDMA radio network computer model, TELE*design, which can be used for RF planning of CDMA-based cellular and PCS systems is also discussed.
