A communication apparatus includes a wireless transceiver that transmits data packets including background traffic data packets and a transceiver control unit that controls transmission by the wireless transceiver of the data packets. The transceiver control unit receives, prior to their transmission, all data packets that are to be transmitted by the wireless transceiver. The transceiver control unit includes an aggregation unit that aggregates all background traffic data packets received by the transceiver control unit over an aggregation period of a certain maximum duration and causes the wireless transceiver to wirelessly transmit the aggregated background traffic data packets only after the aggregation period has expired.
