Abstract

We propose the method of the interference evaluation between the UWB and the wireless LAN by using the GTEM cell that can test the receiver with the antenna built-in type in the paper. We show that the GTEM cell can be used in the frequency band of DS-UWB by the evaluation of the frequency response. The interference evaluation was conducted between wireless LAN IEEE 802.11 a and DS-UWB. As a result, even when the UWB signal is smaller than the receiver noise of wireless LAN, the throughput characteristics deteriorate than those in a case of the noninterference. Moreover, the signal of the DS -UWB was nearly equivalent to the AWGN in a case of the throughput variation of 64QAM Finally, we evaluated the separation distances in regulation limits of FCC and Japan.
