Abstract: In an ad-hoc wireless network, a single multicast message can be used to announce availability of queued data to one or more WLAN devices in the ad-hoc network. A wireless network device in the ad-hoc network can determine network identifiers associated with the other wireless network devices in the ad-hoc network for which the queued data is available. The wireless network device transmits the multicast message, which identifies the wireless network devices for which queued data is available, to indicate the wireless network devices that should remain in an active power state. On receiving the multicast message, a receiving WLAN device can read a network identifier bit associated with the receiving WLAN device to determine whether or not the receiving WLAN device should remain in the active power state. This can reduce transmission overhead and improve power savings, efficiency, and data reliability.

Abstract: According to some embodiments, an analog radio receiver circuit is configured alternatively in a full-power mode when the receiver is situated in a cradle and connected to an external power source, and in a power-saving mode when the receiver is not connected to the external power source. In the power-saving mode, a scaled-down power level is supplied to an analog radio signal processing circuit component such as an amplifier, filter, oscillator, or mixer. Scaling down the power supplied to analog circuit components allows reducing their power consumption, at the expense of degraded circuit performance (e.g. increased non-linearity and intermodulation, decreased filter selectivity). Switching between full-power and power-saving modes may be achieved by controlling the connection of internal nodes of the signal processing circuit to a power source, and/or inserting circuit components (e.g. resistors, active devices, filter poles) into the signal processing circuit.
