The visible light communication receiver provides a wide field-of-view and conforms to different surfaces of the Internet of Things shapes such as laptops and smartphones
About
Visible light communication (VLC) systems provide secure high-throughput indoor wireless networking and are ideal for multi-use office environments and Li-Fi (light fidelity) applications. However, vibrations from movements such as typing on a laptop or handling a smartphone may cause a VLC receiver to lose efficient optical signal reception. The UCF-developed VLC receiver contains a design that conforms to the surfaces of different IoT (Internet of Things) shapes such as laptops, smartphones, TV monitors and virtual reality headsets. Experimental results of a prototype VLC system showed a 20 Mbps VLC link over a 7.1 m distance with a bit error rate of less than 10−5. That is, a speed of 0.2 m/s, acceleration of 43.02 m/s2, displacement of 37.74 mm, and frequency of 6.27 Hz. The testing included subjecting the VLC receiver body to intense vibrations.
