ABSTRACT:
Apparatus and method for interfacing a wired communications network (12) to a wireless communications network (13). Both networks operate with a CSMA protocol. An interface unit (16) includes circuitry (28) for bidirectionally interfacing to the wired medium for transmitting messages thereto and for receiving messages therefrom. The interface unit also includes circuitry (29, 22, 24, 26) for bidirectionally interfacing to the wireless medium for transmitting messages thereto and for receiving messages therefrom. The interface unit further includes logic (28) for bidirectionally routing messages received from the wired medium to the wireless medium and for routing messages received from the wireless medium to the wired medium. A further feature of the interface unit is a collision detector (30), responsive to the reception of a rebroadcast wireless transmission, for comparing the transmitted message to the received rebroadcast message to determine if a collision has occurred.
