Abstract
A wireless infrared (IR) communications system (100) for communicating packetized information (302) between a control module (12) and a plurality of UMs (14) via infrared transceivers (300/320) is described as having a selectable communications path. In this system at least the user module (14) has a plurality of IR device arrays (A1-A6) for receiving IR signals (312/312') in relatively narrow IR field of view sectors, and selection circuit (20), coupled to said plurality of IR device arrays (A1-A6), for selecting a communication path between the control module (12) and one of said plurality of IR device arrays (A1-A6), based at least partly on received signal (302') qualtity, so as to overcome reception errors caused by multipath interference.
