|
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).ʜᴏᴘᴇ ɪᴛ ʜᴇʟᴘs ᴜ |
