ABSTRACT:
In a method of operating a wireless local area network (10), a transmitting station (12) senses that the medium is free and then transmits a first portion (43) of a message (40), including destination and source addresses. Message transmission is then interrupted for a response window period (53) during which a destination station (12) should transmit a response message 42 also containing said source and destination addresses. If the transmitting station (12) does not receive a correct response message (42) then it transmits a JAM signal during a JAM window (65) following the response window (53), thereby indicating to all stations (12) that a collision has occurred. All stations not transmitting a JAM signal monitor the JAM window (65) and are thus informed whether or not a collision has been detected.
