Abstract:
A network having a plurality of terminals in a building occupied by human beings, said network comprising:a first terminal having a transmitter and a receiver, a second terminal which is remotely located from the first terminal, said second terminal having a transmitter and a receiver, each transmitter and receiver having an optical centerline, the optical centerline of the first terminal transmitter being offset from the optical centerline of the second terminal receiver, and the optical centerline of the second terminal transmitter being offset from the optical centerline of the first terminal receiver; and each transmitter having a laser source for generating a laser beam, the laser beam from the first terminal transmitter being of sufficient power and diverging from the laser source at a sufficient angle to establish optical communication with the second terminal receiver despite misalignment therebetween, and the laser beam from the second terminal transmitter being of sufficient power and diverging from the laser source at a sufficient angle to establish optical communication with the first terminal receiver despite misalignment therebetween.
