The Smart Room: a 100 Mb/s integrated optical access point transceiver for indoor visible light communication

Recent developments in visible light communication (VLC) technology have solidified utilizing light-emitting diodes (LEDs) for not only illumination, but also optical wireless communication. This paper presents a novel optical access point transceiver that features addressable arrays of LEDs and photodetectors. The transmitter array enables combined illumination control and serial data transmission for an array of 16 LEDs producing an aggregate data rate of 100 Mb/s. The receiver consists of a 16-element array of broadband receiver channels. Designed in a 0.5 μm CMOS process to enable miniaturization and VLC system integration, the transceiver is capable of processing multiple user requests.
