USB는 사용의 편리성, 넓은 확장성을 기반으로 PC 역사상 가장 성공적인 접속 장치로서, 현재까지 20억 개 이상이 사용되고 있고, USB가 장착된 장치의 종류 및 사용 개수도 빠르게 증가하는 추세이다. 이와 같은 USB의 발전에 힘입어 유선의 속도와 보안성에 무선의 편리함을 추가한 무선 USB 1.0 규격이 2005년 5월 발표되었으며, 상용 제품도 속속 출시되고 있다. 본 고는 유선 USB 2.0 기술에 기반하고 무선 매체로서 UWB를 이용하는 무선 USB의 기술 및 표준화 동향에 대하여 소개하고, 무선 USB 기술의 특징 및 국내외 연구 동향에 대하여 살펴보고자 한다.
