Abstract

Aspects of a method and system for detecting Bluetooth signals utilizing a wideband receiver are provided. In this regard, a portion of a frequency band may be scanned multiple times, where each scan comprises receiving signals present in the scanned portion of the frequency band. Based on results of a Fast Fourier Transform performed on the received signals, presence of one or more Bluetooth transmissions in the received signals may be detected. In instances that a Bluetooth transmission is detected, a type of the Bluetooth transmission may be determined based on a number of the scans in which the Bluetooth transmission was detected. In instances that a detected Bluetooth transmission is a page, a Bluetooth transceiver in the wireless communication device may be powered up and/or enter a page scanning mode. The scans may be performed by a wireless local area networking receiver within the wireless communication device.
