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.
