A 100 Mbit/s tracked optical wireless telepoint

This paper describes the design, construction and testing of a demonstration 100 Mbit/s tracked optical wireless telepoint system. The prototype uses switched linear laser and detector arrays, each imaged onto a small part of the total area, to allow wide coverage at high data rates. A separate tracking system monitors the relative mobility of nodes and switches the transceiver elements to maintain communication. A combination of operation at 1500 nm and a large number of switched laser elements (16) result in Class 1, eye safe, operation.
