In this paper, we present an analytical model to quantify the effect of the Ultra-Wide Band (UWB) transmitters on the CDMA-PCS downlink range and normalized capacity. The effect is given for different configuration and environments. Our analysis shows that, for a single UWB transmitter, an UWB power density of 驴78dBm/MHz is the maximum permitted power density to have only PCS macrocell capacity reduction of 1% when the distance between the PCS mobile and the UWB transmitter is 1 m. For the multiple UWB transmitters case, a power density of 驴80dBm/MHz, is the maximum permitted power density to have only PCS macrocell capacity reduction of 1% when the distance between the PCS mobile and the UWB transmitter is 1 m.
