차세데 홈네트워크 환경하에서는 다양한 데이터 통신 무선기기들이 홈/오피스에서 공존할 것이다. 예를들어 무선랜, 블루투스(Bluetooth), 지그비(Zigbee), 무선 USB, UWB(Ultra Wideband) 등이 함께 주파수를 공유하게 될 것이며, 특히 ISM 대역은 서비스, 산업, 의료용 등으로 다양한 응용이 가느하기 때문에 전파 간섭이 예상된다. 본 논문에서는 IEEE 802.11b 무선랜(WLAN)과 IEEE 802.15.4 저전력 저속 무선팬(WPAN) 무선기기에 대하여 간섭실험을 하였으며 두 무선기기가 상호 공존할 수 있는 공유 조건에 대해 분석하였다. 무선랜(WLAN)과 무선팬(WPAN)의 주파수 대역이 완전히 오버랩된 경우 간섭 레벨과 무선팬의 패킷 전송 횟수를 변화 시켜 상호간의 간섭 영향 저도를 측정하고 상호 무선기기간의 간섭 결과를 바탕으로 상호 무선기기간의 주파수 공유 조건을 제시하고자 한다.
