Abstract

This paper presents the interference impact of Ultra Wide-Band (UWB) sensor using frequency of 3.5 GHz on 3G mobile system in Korea. The Minimum Coupling Loss (MCL) method and Spectrum Engineering Advanced Monte Carlo Analysis Tool (SEAMCAT) were used to evaluate the interference impacts of UWB sensor on 3G mobile system. The minimum allowable distance between UWB interferer and the victim receiver is required 0.09 m in indoor environment; in the case of multiple UWB interferers in outdoor environment, the maximum allowable UWB transmitting Power Spectral Density (PSD) should be-93.1 dBm/MHz below to guarantee co-existence with 3G mobile system.
