A mechanism that reduces power consumption of a transmitter/receiver circuit
in
a wireless device. The transmitter/receiver circuit is powered down to a reduced-power
state after transmitting a message. The reduced-power state is too low to be able
to transmit or receive information. Round trip statistics regarding how low it
typically takes to receive a response to the message are then used to determine
when to power up the transmitter/receiver circuit to the extent that it could receive
the response. Accordingly, by being powered up for only a window of time in which
the receipt of the response would likely occur, the transmitter/receiver circuit
consumes less power while still likely receiving the response. The window of time
may be adjusted as appropriate for the importance of the information, the performance
of the specific wireless network, and the sensitivity of the wireless network to
not receiving the response.
