Abstract: Aspects of the disclosure permit agile acquisition of a location service in a device. In one aspect of such acquisition, the device can rely on location signals available globally in order to determine a region associated with the device, and in response to determination of the region, the device can acquire service information representative or otherwise indicative of the location service based at least on the region. In another aspect, the device can be configured to consume the location service. The agility of such acquisition can stem from the absence of (i) scanning for location services associated with the area in which the device is present and/or (ii) a predefined pool of location services established in production of the device.

Abstract: A system includes a radar antenna and a radar controller. The radar controller generates two narrowband radar signals, each narrowband radar signal having substantially constant frequency, the frequencies of the two narrowband radar signals differing from one another. The controller operates the radar antenna to transmit each of the generated narrowband radar signals as a transmitted signal, each transmitted signal being characterized by a transmitted power. The controller also measures a received power of received signals that are received by the radar antenna, each received signal including a portion of a corresponding one of the transmitted signals that was returned from an object or from a calibration surface at a known calibration range. A processor operating in accordance with programmed instructions calculates a range to the object on the basis of the transmitted and received powers.

Abstract: A method and system for wireless data transmission between at least three stations use multiple frequency bands for simultaneous channel communications. The method includes transmitting a Request To Send (RTS) packet from a first station to an intermediate second station over a first frequency band. Two Clear To Send (CTS) packets, which CTS packets include transmission timing information, are then transmitted from the second station simultaneously both to the first station and to a third station. The CTS packet sent to the first station is transmitted over the first frequency band and the CTS packet sent to the third station is transmitted over a second frequency band. A data packet from the first station is then transmitted to the second station. The third station suspends, based on the transmission timing information included in the CTS packets, any unicast transmission to the second station during the transmission of the data packet from the first station to the second station.

Abstract: A method and apparatus for frequency correction of a signal in a wireless local area network (WLAN) communication system is disclosed. The signal is processed to determine a frequency offset estimate which is a frequency deviation of the signal from a local oscillator. The signal is then shifted by an amount corresponding to a frequency correction estimate where the frequency correction estimate is an averaged value of the frequency offset estimate and at least one prior frequency offset estimate. Finally, the frequency correction estimate is utilized to correct signals in the WLAN communication system.
