Abstract :
The reverse link capacity of a cellular network based on IS-95-B CDMA standard is investigated. The results reflect various tradeoffs associated with having different rate set voice users (8 kbps and 13 kbps vocoders) and data users (9.6, 19.2, 28.8, 38.4, and 57.6 kbps) simultaneously in the network. Different frame error rate choices for voice and data users lead to different performance. The tradeoffs associated with the variety of technical options show that although voice users can be mixed with low-speed data users, the performance degrades very rapidly with the introduction of high-speed data users
