Aspects of a method and system for detecting Bluetooth signals utilizing a
wideband receiver are provided. In this regard, a frequency band may be
scanned by receiving signals on each of a plurality of sub-bands for an
amount of time, the energy received in each band may be compared to a
threshold, and whether each sub-band comprises a Bluetooth transmission
may be determined based on a FFT. Additionally, the FFT may enable
determining on which Bluetooth channel a detected transmission occurred.
A FFT may be performed when energy detected in a sub-band is higher than
a threshold. The sub-bands may each be a WLAN channel. A type of a
detected Bluetooth transmission may be determined based on a number of
scans in which the transmission is detected. Each sub-band may be
received for less than or equal to 68 .mu.s divided by the number of
sub-bands.
