RESUMO
In this work we present an investigation on the traffic capacity of CDMA systems for cellular mobile communication, with emphasis on the Erlang capacity. It is mitially made a brief analysis of the capacity in traditional FDMA/TDMA cellular systems. We then present a basic analysis of the traffic capacity in CDMA systems, assembling the models and results from several works found in the literature. Finally, we investigate the effect in the system capacity of several aspects of CDMA systems, that had not been previously addressed. We have thoroughly examinated the limitation in the number of available channels, the possibility of a waiting queue, the temporal behaviour of the interference, the actual increase in capacity obtained through sectorization and the effect of soft-handoff in the capacity.
