Infrared Communications Network
US Patent:
5099346, Mar 24, 1992
Filed:
Jan 27, 1988
Appl. No.:
7/149049
Inventors:
Richard M. Lee - Wilmette IL
Gary T. Cromack - Greenfield MA
Gary T. Cromack - Greenfield MA
Assignee:
Spectrix Corporation - Evanston IL
International Classification:
H04B 1020, H04B 1000, H04J 1400
US Classification:
359118
Abstract:
An infrared data communications network in which groups of personal computers and associated peripherals may communicate by infrared signals with each other. The system utilizes a error correction and a packet switched protocol which allows any terminal to select communications with any other terminal or terminals without degradation of the error rate. Error free transmission is maintained by means of error correcting encoding and a handshake protocol. The packet switched protocol permits any terminal to function as a store and forward repeater thus making the system more reliable and less susceptible to beam blockage.
