Indoor optical/radio wireless communication:demonstration of high-def video streaming using steerable infrared beams

A hybrid wireless indoor system has been designed and validated which realizes ultrahigh-capacity transmission downstream by directing narrow infrared beams to mobile devices individually, using an AWGR-based module for wavelength-controlled 2D beam steering. For upstream, 60GHz radio techniques are employed which are also used to localize the devices and enable automatic infrared beam steering by a remotely located central communication controller. In a laboratory demonstrator, automatic mobile device localization and IR beam steering is demonstrated, and the transmission performance of conveying two high-def video streams optical-wirelessly to two users individually is demonstrated.
