This work demonstrates a record 160 m long visible light communication (VLC) link using LED transmitters and an image sensor-based receiver, for distance-critical applications. This marks the longest VLC distance achieved to date, using a combination of novel modulation technique at the transmitter and an undersampling-based receiver incorporating adaptive threshold decisioning. Experimental results demonstrate low bit error rate (BER) performance at the achieved communication distance.
