Abstract
A method and apparatus for: receiving a radio frequency (RF) signal on a first channel; determining a radio signal strength of the RF signal; performing a correlation of the RF signal with a predetermined sequence of a wireless data packet to determine whether the RF signal contains the predetermined sequence; in response to the RF signal not containing the predetermined sequence, generating an indication that the RF signal is not a wireless data packet; and determining whether the radio signal strength of the RF signal exceeds a predetermined threshold. In response to i) the radio signal strength exceeding the predetermined threshold and ii) the indication being generated: measuring a parameter associated with the RF signal; determining whether the RF signal is a radar signal based on the parameter; and changing from the first channel in response to the RF signal being determined to be a radar signal.
