VLC Introduction

  • VLC (Visible Light Communication)
    • New communication technology using “Visible Light”
    • Wavelength between ~400nm (750THz) and ~700nm (428THz)
  • General characteristic
    • Visibility : Aesthetically pleasing
    • Security : What You See Is What You Send
    • Unregulated : No regulation in optical frequency
    • Health : Harmless for human body
    • Non-interference with other devices

LED as Light Source for VLC

  • Relatively faster response time
  • Difficult to damage with external shock
  • High tolerance to humidity
  • Minimal heat generation
  • Light Emitting Diode (LED)
    • Small
    • Relatively Long life
    • More efficient
    • Low power consumption
