Abstract This invention generally relates to interference mitigation, and more specifically to interference mitigation in wireless communications networks. The proposed solution takes advantage of the clear channel assessment (CCA) function used by WLAN networks. Hence, by jamming the interfering WLAN channel during a predetermined time period, the interfering WLAN network is forced to withhold transmissions on the WLAN interfering channel during a backoff period of time. The solution of the subject application makes use of this backoff period to enable a WPAN network to transmit critical information such as, but not limited to, a request for changing the current working frequency.
