What is Visual Light Communication(VLC)?

1.	What is Visual Light Communication(VLC)?
Answer» ANSWER: VISIBLE light communication (VLC) is a data communications variant which uses visible light between 400 and 800 THZ (780–375 NM). VLC is a subset of optical wireless communications technologies.The technology uses fluorescent lamps (ordinary lamps, not special communications devices) to transmit signals at 10 kbit/s, or LEDs for up to 500 Mbit/s over short distances. Systems such as RONJA can transmit at full Ethernet speed (10 Mbit/s) over distances of 1–2 kilometres (0.6–1.2 mi). ----------------------------------------------------------------------------------------------------------------- Thank you
