Abstract

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.
