摘要:
Methods and systems for wireless communication are disclosed and may include controlling one or more scans of a received signal detection frequency across a frequency range and storing a magnitude of the received signal at each frequency where the magnitude exceeds a threshold level. A type of one or more signals in the received signal may be determined based on a bandwidth of the signals. A Bluetooth page/inquiry scan may be initiated if the determined type is a page/inquiry signal, and scans may be continued if the determined type may not be a page/inquiry signal. The scans may be repeated on a periodic basis and may be controlled utilizing a voltage controlled oscillator. Each of the scans may include a plurality of discrete frequency steps or a continuous frequency ramp. The controlling may include a start frequency, an end frequency and a frequency step size for the scans.

摘要:
Methods and systems for wireless communication are disclosed and may include sweeping a signal detection frequency one or more times across a plurality of steps in a frequency range. The measured signal strength at each step may be compared to a threshold, and a status may be stored, which may depend on the presence of a measured signal strength above threshold. The detection frequency may be swept utilizing a voltage controlled oscillator, which may be tuned via a control voltage and/or calibration capacitors. Steps may be skipped when a measured signal strength may be greater than the threshold, and may occur after multiple above threshold measurements. The steps may have variable frequency width, and the range may include the Bluetooth band from 2.40 GHz to 2.48 GHz. The frequency may be swept over a subset of the Bluetooth band, and may be swept on a periodic basis.

Aspects of a method and system for Bluetooth 802.11 alternate MAC/PHY (AMP) transmit power control (TPC) may include one or more processors, receiver circuits and/or transmitter circuits that are operable to determine a maximum input level based on signals received via a Bluetooth basic rate (BR) connection and/or via a Bluetooth extended data rate (EDR) connection. The processors and/or circuits may be operable to determine a transmitted signal power level based on the determined maximum input level. The processors and/or circuits may be operable to transmit subsequent signals via a distinct Bluetooth connection based on the determined transmitted signal power level. The data rate for signal transmission via the distinct Bluetooth connection may exceed the data rate for signal transmission via the BR connection and the data rate for signal transmission via the EDR connection.

Aspects of a method and system for a fast power control mechanism for Bluetooth devices may include receiving from a first Bluetooth device, a request for a transmit power adjustment for one or more operating modes. A step size may be received for the transmit power adjustment via the received request. The transmit power may be adjusted as a function of the step size. A feedback message may be sent to the first Bluetooth device, wherein the feedback message may indicate a status of the adjusting. The transmit power adjustment may be requested via a Link Management Protocol (LMP) message. One or more operating modes may comprise a Bluetooth Basic Rate (BR) mode, and/or a Bluetooth Enhanced Data Rate (EDR) mode.
