Abstract
A stationary optical antenna forming a part of a full duplex optical communication system, includes optical emitter and receptor devices having peak power axes, and a mounting arrangement for positioning the devices at an elevated location within a room with their axes directed downwardly at a given angle to a horizontal plane, based upon the height of the devices above the floor, thereby enabling remote portable transceivers to be able to communicate therewith within the same room. Baffles help prevent interference between the emitters and receptors, and a compensation circuit is employed to enable the optical communication to take place, even in bright light conditions.
