본 고에서는 반도체 LED(Light Emitting Diode)를 이용한 가시광 무선통신 기술에 대한 국내외 표준 동향을 기술한다. 가시광 무선통신은 조명 및 통신을 융합함으로써 녹색성장 저탄소의 효과가 있으며, 생활의 불편함이 없이 저탄소를 실현할 수 있다. 저탄소 LED는 조명 인프라를 바꾸는 신성장 기술로 급부상하고 있다. LED는 백열전등에 비하여 전기 절감 효과가 높고, 형광등에 비하여 수은을 사용하지 않아 친환경적이다. 통신 및 조명 환경 변화에 부응한 기술로서, LED 조명과 동시에 통신을 할 수 있는 가시광 무선통신 융합 기술이 등장하였다. 본 고에서는 조명과 통신의 전혀 다른 산업이 융합된 기술로 탄생하게 된 기술적 배경, 가시광 무선통신의 국내 TTA 표준 및 국제 IEEE 802.1.57 표준 동향 등을 설명한다.
