Full duplex communication system and method of using same
First Claim
1. An optical communication system for facilitating full duplex communication between remote transceivers comprising:
- a base station transceiver for receiving optical communications from one of the remote transceivers and for repeating the optical communications to at least another one of the remote transceivers;
said base station transceiver having an antenna assembly and a stationary transceiver unit connected electrically to said antenna assembly; and
means for mounting said antenna assembly at a height H above a floor at one end of a room and inclined from the vertical by an angle A to enable the base station transceiver unit to direct a peak power axis of optical radiation downwardly at an angle B form the horizontal toward a wall at the opposite end of said room, said axis intersecting said wall at a distance D from said base station transceiver unit, and at a height HT above the floor, the height HT being equal to the height of the remote transceiver within the same room.

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.

9. A method of communicating optically comprising:
-
using a base station having a transceiver and an antenna assembly for receiving optical communications and for directing the received optical communications to at least one remote optical transceiver within the same room; mounting said base station antenna assembly at a height H above the floor of the room and inclined downwardly away from the vertical by an angle A to direct an optical radiation node having a peak power axis of optical radiation inclined downwardly at an angle B from the horizontal toward an opposite end of said room to cause said radiation axis to intersect a wall disposed at a distance D from said base station transceiver, and at a height HT above the floor, the height HT being equal to the height the remote transceiver is disposed within the same room.
