Description / Abstract:
This standard defines a PHY and MAC layer for short-range
optical wireless communications using visible light in optically
transparent media. The visible light spectrum extends from 380 nm
to 780 nm in wavelength. The standard is capable of delivering data
rates sufficient to support audio and video multimedia services and
also considers mobility of the visible link, compatibility with
visible-light infrastructures, impairments due to noise and
interference from sources like ambient light and a MAC layer that
accommodates visible links. The standard adheres to applicable eye
safety regulations.
Purpose The purpose of this standard is to
provide a global standard for short-range optical wireless
communication using visible light. The standard provides (i) access
to several hundred THz of unlicensed spectrum; (ii) immunity to
electromagnetic interference and noninterference with Radio
Frequency (RF) systems; (iii) additional security by allowing the
user to see the communication channel; and (iv) communication
augmenting and complementing existing services (such as
illumination, display, indication, decoration, etc.) from
visible-light infrastructures.
