Abstract
The present invention is an apparatus for wireless communications of information between two locations. A transmitter means modulates the information into infrared radiation at a first location. The infrared radiation is transmitted by the transmitter to a reflecting surface along a straight line path which is transparent to the infrared radiation. The infrared radiation is reflected at the reflecting surface forming reflected infrared radiation. A receiver means for receiving the reflected infrared radiation from the reflecting surface is positioned at a second location. The second location and the reflecting surface have a straight line path therebetween which is transparent to the infrared radiation.
