摘要：
In this paper the overlay of a wireless local loop system on CDMA2000 cellular system is proposed. The CDMA2000 system uses 5, 10, 15 and 20 MHz of dispersion bandwidth and the WLL system uses 1.25 MHz of dispersion bandwidth. In this way, it is possible to have 3, 4, 8, 9, 12 and 16 frequency allocations for the WLL system depending of the different bandwidths of the CDMA2000 cellular system. As an overlay system the WLL can use only a fraction of the frequency allocations according to a co-frequency allocation reuse distance, similar to FDMA and TDMA cellular systems. With this idea less interference is introduced in the WLL system (in the limit, the capacity will be similar to the isolated cell) keeping at the same value the interference introduced in the CDMA cellular system.
