A device comprising: a transceiver operable in a first or second mode and configured to receive packets from a remote device, each packet comprising an indication of whether or not the remote device has a further packet to transmit, wherein: in the first mode the transceiver: (i) sends a polling message in response to receiving the indication of a further packet for transmission; and (ii) listens for that further packet; and in the second mode the transceiver: (i) does not send a polling message in response to receiving the indication of a further packet for transmission; and (ii) listens for packets regardless of whether a received packet indicates that there is a further packet to transmit or not; and a controller configured to monitor an activity level for the transceiver and cause the transceiver to operate in the first or second mode in dependence on the activity level.

A communication system supports communication between an end node () of a vehicle () and a remote correspondent node () via a fixed network () which comprises a plurality of wireless access points () with a directional antenna arrangement for mm wave radio communication using directional beams. A vehicle () comprises wireless modems () employing electronically steerable beamforming directional antennas for establishing mm wave radio communication links to the access points (). The air interface communication may use a frequency channels selected from a set of available frequency channels and using a transmission scheme from a set of available transmission schemes. The access points () transmit a first beacon data set in a frequency channel using a common transmission scheme and a second beacon data set using a different transmission scheme which is also used for data communication. The first beacon data set comprises an indication of the transmission schemes used for data communication for the access point ().
