A communication gateway includes a communication unit that transmits and receives messages in order to communicate with at least one remote communication node on a first wireless communication network according to a protocol which includes network access control (MAC), and receives messages originating from at least one transmitter transmitting messages on a second wireless communication network according to a protocol which does not include network access control (MAC). The protocols of the first and second wireless communication networks use a same physical layer (PHY). The communication gateway also includes a processing unit associated with the communication unit that differentiates between the received messages originating from the first wireless communication network and the received messages originating from the second wireless communication network by analyzing header information contained in the received messages originating from the first wireless communication network and in the received messages originating from the second wireless communication network.
