Gigabit Rate Mobile Connectivity Through Visible Light Communication
Visible Light Communication (VLC) is a short range wireless transmission of visible light through free space. The light source can be based on Light-Emitting Diodes (LEDs), that are becoming common use in the authors' future connected home where they can be simultaneously used for both illumination (i.e. LED TVs, Light bulbs, etc.) and communication with appropriate photodiodes in the receiver side. VLC can be adapted to mobile devices enabling new types of short range applications such as HD video streaming. However, many of the new emerging mobile applications require increasingly high data rates; some can even exceed 1 Gbps.
