UWB 무선기술은 초광대역 특성에 의한 높은 전송속도와 기존의 무선장치들과 상호 간섭영향 없이 주파수를 공유하여 사용할 수 있다는 장점 때문에 새로운 방식의 근거리 무선통신 기술로 급부상되고 있다. 특히 IEEE802 15.3에서 UWB 무선기술을 WPAN으로 사용하기 위한 표준화 작업이 진행되고 있어 현재 가장 널리 사용되고 있는 IEEE802.11 및 Bluetooth 장치와 향후 실내 환경에서 공존할 가능성이 매우 높아지고 있으며 이에 따른 장치 상호간 간섭영향 평가가 요구되고 있다. 본 논문에서는 2.4 GHz 대역 IEEE 802 11b 무선랜 장치를 사용하는 실내 환경에서 UWB 무선장치가 공존할 경우 무선랜 장치의 Packet Failure Rate 및 Throughput 측정을 통해 UWB 신호가 무선랜 장치에 미치는 간섭영향을 분석하였다.
