Claim 0:
1. A device capable of communicating according to a wireless communications protocol, the device comprising:
a transceiver 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, the transceiver being operable in a first mode or a second mode, wherein:
in the first mode the transceiver is configured to: (i) send a polling message to the remote device in response to receiving the indication of the remote device having a further packet to transmit; and (ii) listen for that further packet; and
in the second mode the transceiver is configured to: (i) not send a polling message to the remote device in response to receiving the indication of the remote device having a further packet to transmit; and (ii) listen for packets regardless of whether a received packet indicates that the remote device has a further packet to transmit or not; and
a controller configured to:
monitor an activity level for the transceiver by monitoring for a change in an identifier of one or more remote devices; and
cause the transceiver to operate in the first mode or the second mode in dependence on the monitored activity level.
