A cellular optical wireless system demonstrator

The features of a cellular optical wireless link employing a multi-element receiver and transmitter was discussed. The receiver structure takes receiving signals to achieve a high optical gain and wide field-of-view to realize solid-state tracking. The receiver is AC coupled for rejection of ambient light noise and uses it for reducing baseline wander. The system is able to track the transmitter beam as the receiver moves in two dimensions across the coverage area of the transmitter
