Visible Light Communications
 
Visible Light Communications (VLC) is a data communications medium which uses visible light between 400 and 800 THz (780 to 375 nm). Since first invented by Alexander Graham Bell in the 1880s the technology has been largely dormant. More recently, enhancements in LED technology and processing capability has allowed VLC to become practical. VLC provides some key benefits that include:
  • Inherently secure (control over propagation)
  • No interference with other RF systems
  • No frequency regulations
  • Directional (control of light/communications area)
  • High data rate (400THz bandwidth)
