국내외 에너지 정책에 힘입어 LED 조명 보급이 늘어나면서 관련된 광 무선 기술이 주목받고 있다. 적외선 무선통신 포트를 장착한 상용 제품들이 수 년 전부터 공급되었다. 이들이 시장을 주도하지는 못했지만 LED 조명을 이용한 가시광 무선통신은 조명의 커버리지 안에서 안정된 출력과 채널 환경이 매력적이다. 하지만 조명 기능을 우선적으로 유지시켜야 하는 상황에서 광 신호를 다루는 해결책이 충분하지 않아 고속 통신에 제약이 따른다. LED 조명 융합 기술을 무선통신 기술 관점으로 접근하는 새로운 연구가 다양하게 이루어지고 있다. 무선통신은 RF 기반의 시스템이 대부분이지만, 무선 패킷 수요 증가를 고려하여 새로운 주파수 자원에 의한 근거리 무선 보조 수단으로 광 무선통신이 제안되고 있다. 이에 관하여 LED 조명과 연계한 광 무선통신 기술의 현황과 전망을 기술하였다.
