Describe visible light communications (VLC).
What will be an ideal response?
A new type of WPAN based not on infrared light but on visible light (which is adjacent to infrared on the frequency spectrum) is gaining popularity. It is known as visible light communications (VLC) and standards are being developed by the IEEE committee 802.15.7. VLC transmits data by the intensity of the modulating optical source, such as LEDs and laser diodes (LDs). Because this modulation is faster than the human eye can detect, humans cannot perceive a transmission taking place.
