1. A system comprising an interference detection means for detecting interference on wireless radio frequencies, wherein the interference detection means comprises a discrimination means for:

  • discriminating between interference caused by a Wireless Local Area Network, herein after referred to as WLAN, and interference caused by other radio applications;

    discriminating between interference from a narrowband source and interference from a broadband source, wherein when the discrimination means determines a detected interference is from a broadband source the discrimination means determines the detected interference is caused by a WLAN; and

    wherein the interference detection means is adapted for measuring a total interference in a frequency band of interest and an aggregate interference from narrowband signals in the frequency band of interest, and wherein the discrimination means is adapted for determining the difference between the total interference and the aggregate interference and based thereon deducing if the detected interference is from a narrowband source or a broadband source.
