Definition of optical wireless communication PCMag
Optical wireless communications (OWC) is a form of optical communication in which unguided visible, infrared (IR), or ultraviolet (UV) light is used to carry a signal. It is generally used in short-range communication. OWC systems operating in the visible band (390–750 nm) are commonly referred to as visible light … See more Wireless communications technologies proliferated and became essential very quickly during the last few decades of the 20th century, and the early 21st century. The wide-scale deployment of radio-frequency technologies … See more Variations of OWC can be potentially employed in a diverse range of communication applications ranging from optical interconnects within integrated circuits through outdoor inter-building links to satellite communications. OWC can be divided … See more • Daukantas, Patricia (March 2014). "Optical Wireless Communications: The New Hot Spot" (PDF). Optics and Photonics News. 25 (3): 34–41.
