A New Method of Interference Evaluation Between UWB System and Wireless LAN Using a GTEM Cell

We propose a method of interference evaluation between the UWB and the wireless LAN using the GTEM cell that can test the receiver with a built-in type antenna. The interference evaluation was conducted between wireless LAN IEEE802.11a and DS-UWB. As a result, even when the UWB signal is smaller than the receiver noise of wireless LAN, the throughput characteristics deteriorate compared to the case of noninterference. Moreover, the signal of the DS-UWB was nearly equivalent to the AWGN in the case of throughput variation of 64QAM. We evaluated the separation distances in regulation limits of FCC and Japan. The measurement results for the amplitude probability distribution (APD) of the interfering UWB signal are also discussed.
