3、ndards InstituteAbstract: A PHY and a MAC layer for short-range optical wireless communications using visiblelight in optically transparent media are defined. The visible light spectrum extends from 380 nm to780 nm in wavelength. The standard is capable of delivering data rates sufficient to support

4、 audioand video multimedia services and also considers mobility of the visible link, compatibility withvisible-light infrastructures, impairments due to noise and interference from sources like ambientlight and a MAC layer that accommodates visible links. The standard adheres to applicable eyesafety
