Air Scan Profile

Air Scan Profile

The air scan profile is used for radio calibration, spectrum analysis, WLAN device location, and Wireless Intrusion Detection System (WIDS) data analysis. An AP periodically scans surrounding radio signals and reports the collected information to an AC or server.

  • Radio calibration

    An authorized AP scans surrounding radio signals, collects information about surrounding authorized APs, rogue APs, and non-Wi-Fi devices, and reports the information to an AC.

    For the detailed configuration, see Configuring Radio Calibration in the Configuration-Radio Resource Management Configuration Guide.

  • Spectrum analysis

    An AP detects different types of interference resources on wireless networks, and displays the information to users. Users can then use the information to locate these interference sources. This function improves user experience.

    For the detailed configuration, see Configuring Spectrum Analysis in the Configuration-Spectrum Analysis Configuration Guide.

  • WLAN device location

    An AP collects radio signals, and reports the location information to the positioning server. Alternatively, the AP can send the location information to the AC, which filters the information and sends the filtered information to the positioning server. An AP can collect radio signals in either of the two modes:
    • The AP collects Received Signal Strength Indicator (RSSI) information of WLAN terminals and rogue APs and reports the information to the positioning server. The information is then used to locate WLAN terminals or rogue APs
    • An AP scans spectrums and reports fast Fourier transform (FFT) results of radio signals to an AC. The information is then used to identify non-Wi-Fi interference sources.

    For the detailed configuration, see Configuring WLAN Tag Location in the Configuration.

  • WIDS data analysis

    A monitor AP scans channels to monitor information about neighboring wireless devices, collects information about neighboring wireless devices by listens on WLAN packets sent from neighboring wireless devices, and periodically reports collected information to an AC. The AC then uses the information to determine rogue devices.

    For the detailed configuration, see Configuring Rogue Device Detection in the Configuration-WLAN Security Configuration Guide.

The air scan profile takes effect only after it is referenced by the radio profile.
