This research has shown that the emission PSD of UWB systems are likely to be so harmful to WiBro system capacity. As shown in the results of the assessment of the potential interference caused by UWB interfering transmitters, the maximum UWB PSD to WiBro system at 2.3 GHz frequency bands must be restricted by approximately -80 dBm/MHz according to UWB densities and should be rigidly limited by less than 30 dB than the FCC provision of -51.3 dBm/MHz to guarantee conflict-free coexistence between UWB and WiBro system in the assumed scenarios for evaluation of UWB interference impacts. Also, the maximum UWB PSD may be dependent on the different services of UWB communication applications. In addition, if multiple UWB interfering transmitters are close to WiBro, victim receivers don't exist, the total throughput loss and the outage at multi-rate are not regarded as the performance degradation for WiBro systems
