Abstract: An access point including a first processor and a network device. The network device is separate from the first processor. The first processor transitions between first and second power modes. The network device includes a second processor and first and second interfaces. The second processor, while the first processor is in the second power mode, (i) causes the second interface to transmit a beacon, or (ii) receives a probe request from a client device. The second interface, while the first processor is in the second power mode, (i) transmits a probe response over a wireless local area network to the client device based on the beacon or the probe request, and (ii) receives an authentication frame from the client device based on the probe response. The second processor, in response to the authentication frame, signals the first processor via the first interface to transition to the first power mode.

Abstract: In a method of calibrating a wireless communication device, a first sounding packet is transmitted from the wireless communication device to a calibration station. A first channel descriptor is generated based on the first sounding packet. A second sounding packet is transmitted from the calibration station to the wireless communication device. A second channel descriptor is generated based on the second sounding packet. The first channel descriptor and the second channel descriptor are obtained at a controller. Calibration coefficients indicative of one or both of phase imbalance and amplitude imbalance between a receive radio frequency (RF) chain and a transmit RF chain at the wireless communication device are generated based on the first and the second channel descriptors. The calibration coefficients are sent from the controller to the wireless communication device.

Abstract: A radio frequency transmitting system which includes first and second amplifiers, a power detector, and a calibration module. The first amplifier amplifies an input signal to generate an amplified signal in accordance with a programmable gain. The second amplifier transmits an output signal based on the amplified signal. The output signal is transmitted at a particular power by the second amplifier. The power detector measures the particular power at which the output signal is transmitted by the second amplifier. The calibration module adjusts the programmable gain of the first amplifier by a calibration offset so that the particular power measurement matches a predetermined power. The calibration module includes offset generation modules that each generate a respective calibration offset candidate based on the particular power measurement. The calibration module also includes a selection module that selects, based on the predetermined power, one of the calibration offset candidates as the calibration offset.
