This paper describes the analysis of UWB interference on WiMax systems. Co-existence between these two systems is important due to unlicensed use of 3.1 to 10.6 GHz frequency band by UWB. The interference impact of UWB devices entirely depends on the victim receiver characteristics. From the knowledge of noise density and allowable maximum noise raise in WiMax receiver, maximum permissible interference due to UWB devices is calculated. For the co-existence between UWB Transmitter & WiMax Receiver for the given parameters distance and probability of interference is calculated.
