Overview
IEC 62943:2017 is an international standard developed by the International Electrotechnical Commission (IEC) that defines a visible light beacon system specifically designed for multimedia applications. This standard establishes a unified communication protocol operating at the lower communication layer, leveraging visible light for data transmission. Unlike higher-level communication layers which are application-dependent, IEC 62943 focuses on a unidirectional visible light communication protocol known as the "visible light beacon system."
The standard aims to facilitate efficient and interoperable communication using visible light technology, providing guidelines for physical and frame layers, data transmission methods, and interface protocols. Its scope encompasses multimedia applications that benefit from location-dependent or context-aware services through visible light beacons.
