Abstract: A system includes a radio frequency transceiver. A baseband processor includes an automatic gain control module. The automatic gain control module has a gain that changes from and subsequently returns to a predetermined value each time the radio frequency transceiver receives a radio frequency signal. The baseband processor is configured to selectively generate an interrupt signal each time a radio frequency signal is received based on a magnitude of the change in the gain of the automatic gain control module and a length of time in which the gain returns to the predetermined value. A control module is configured to identify a radio frequency signal received by the radio frequency transceiver as a radar signal in response to the baseband processor having generated a plurality of interrupt signals at substantially equal time intervals.

Abstract: Techniques for establishing a dynamic ad-hoc wireless network are disclosed. A node transitions between wake and sleep modes during periods defined as beacon intervals. Before a network connection is established and while it is awake, the node transmits network connection request and also listens for network activity. If a beacon or response message is not detected while the node is listening, the node enters sleep mode and thereby conserves power. The node optionally changes the duration of its detection period and/or the time at which it listens for network activity relative to the start of each beacon interval. Information elements are optionally included with transmitted beacons or response messages.

Abstract: A system and method are disclosed for controlling transmit power amplification in a wireless transmitting device. A processor receives data to determine whether a communication channel from a transmitting device to a receiving device is strong enough to support a target data transmit rate of the devices with a power amplifier either on or off. The processor controls a switching device between a data transmitter circuit and the transmitter's antenna based on the quality of the communication channel. In a first state, the switching device connects the data transmitter circuit to the power amplifier to increase the strength of the signal communicated to the antenna. In a second state, the switching device bypasses the power amplifier. The power amplifier is turned off when the switch is in the second state, thereby decreasing the power consumed by the transmitting device as it transmits data at the target data transmit rate.

Abstract: A system and method are disclosed for decreasing the amount of power consumed by a data transmitter in a wireless device when transmitting media (audio and/or visual) data or other data received from a media source or other source. A transmission circuit, such as an application specific integrated circuit (ASIC) or WLAN chip, is configured to deactivate the data transmitter for a deactivation interval and aggregate the media data (or other consistent-rate data) in a buffer while the data transmitter is deactivated. At the end of the deactivation interval, the data transmitter is activated and the aggregated data packets are transmitted. The data transmitter may be repetitively deactivated and activated for transmitting the data. The deactivation interval may be based on the data sampling rate, the transmission rate of the data transmitter, the capacity of the buffer, and/or other factors.
