Abstract:Visible light communication has become one hotspot in the research field of wireless communication at home and abroad, and great breakthroughs have been made during the past few years. White light LEDs as the light source, using the high speed light flashing to transmit the information and illumination at the same time, can save energy. In this paper, introduced are the research status, key technologies, application scenarios and the development trends of VLC based on white LEDs.
