ABSTRACT:
An infrared transceiver for use with a computer in a wireless Local Area Network. The transceiver comprises a light emitting diode array and photodiodes. The transceiver is operable in a diffused beam arrangement and a directed beam arrangement. The transceiver is converted to directed beam operation by attaching a user installable collimator. The collimator redirects the beams into parallel beams, and the direction of the parallel beams is controlled through an adjustable tilt stand. The collimator is detachable for converting back to diffused beam operation.
