Indoor optical wireless communication systems based on the visible wavelengths (380-780 nm), also known as the visible light communications (VLC), has emerged as one of the premier solutions for the emerging ├ó┬?┬?last-metre├ó┬?┬? bottleneck due to the huge, practically unlimited license free bandwidths available in the optical domain, high energy efficiency, and low cost of implementation. This emerging green technology, which uses white light emitting diodes based lighting sources, can be utilized as an additional wireless communications technology similar like WiFi and bluetooth to resolve the spectrum congestion currently being experienced in the radio frequency domain and provide much needed higher data rates especially in areas with high population density within an indoor environment. VLC based systems beside general illumination will also offer data communication, indoor localization as well as sensing in both indoor and outdoor environment. VLC has a multitude of applications including underwater communications, car to car communications, intelligent transportation (planes, trains, etc.) medical, financial sector, to name a few. However, there are a number of challenges facing VLC that needs addressing before its widespread deployment. This talk will give an overview of the VLC technology focusing on the key features, recent progress made, research challenges and applications.
