Abstract
A system and method that overcomes the deficiencies of prior optical data communication systems for local area networks by employing a centralized controller in conjunction with a robust protocol and contention scheme. This combination facilitates the transport of data between a number of optical nodes without collision. The invention is particularly suited to transmissions between several mobile optical nodes and one or more stationary network infrared collector/transmitters, allowing communication with the network as the mobile nodes roam from the vicinity of one network infrared collector/transmitter to the next.
