and mobile devices will exceed the traffic from wired devices by 2019. By 2019, wired devices will account for 33% of IP traffic, while Wi-Fi and mobile devices will account for 66% of IP traffic. Although wireless providers are deploying additional access infrastructure by means of new cells and WiFi end points, the limitation is becoming overuse of the existing radio-frequency (RF) spectrum. This manifests as contention and interference, and results in an increase in latency and a decrease in network through put— a “spectrum crunch” [2]. To alleviate this problem, new approaches to realize larger potential capacity at the wireless link are needed, and optical technologies including visible light communication (VLC) are excellent candidates.
