A client terminal, comprising: a first communication circuit (108, 606) for wirelessly communicating over a first communication channel; a second communication circuit (114, 610) for wirelessly communicating over a second communication channel, wherein the second communication circuit is configured to consume less power than the first communication circuit; and a processing circuit coupled to the first communication circuit and the second communication circuit, characterised in that the processing circuit is adapted to: establish communications with a proxy device over the first communication channel and the second communication channel, and switch the client terminal to a power conserving first mode where channel condition feedback data associated with the first communication channel bypasses the first communication circuit and is conveyed to the proxy device via the second communication channel, and wherein the processing circuit is further adapted to: establish a communication session with a networked device via the first communication circuit, wherein periodic heartbeat signals are to be sent by the client terminal to keep the communication session alive; send a proxy request for the proxy device to send the periodic heartbeat signals on behalf of the client terminal and monitor the communication session for a data indicator; and switch to a lowered power second mode where the first communication circuit is idled or disabled while the second communication channel is monitored for a forwarded data message indicator, receive the forwarded data message indicator from the proxy device via the second communication channel; switch to a third mode upon receipt of the forwarded data message indicator in order to receive the data message as part of the communication session via the first communication channel. a first communication circuit (108, 606) for wirelessly communicating over a first communication channel;
