Visible Light Communication，VLC

The led has light except high speed modulation and short response time and so on.
white LED at high rate modulation in flash mode are not easy to take notice. LED in the light mode also provide the functions of data communication with decode device. In data communication, transmitted and received messages with The range of the spectrum in 380~780nm
this utilization will assist us in this communication work. . Owing to its more adjustable parameters,we call this the way(uses visible light to produce the carrier wave) as Visible Light Communication(VLC)
There is tremendous room for Short range security, secure communication, high precision, accurate location, transportation, communication and indoor navigation .
