Additional information:

  • BSSID (Basic Service Set Identifier) – access point identifier, based on wireless module’s MAC address.
  • SSID (Service Set Identifier) – network name (VAP for additional virtual access point SSIDs).
  • Radio name – additional extension for network name in proprietary wireless protocols (Mikrotik, Ubiquiti, Cisco),
  • S↑ – the strongest reported signal level value [dBm].
  • Logs – all reception dates.
  • Mode – wireless network protocol.
  • Approximate location – network’s location and distance based on geolocation:
    1 – Wigle.net database,
    2 – Google Geolocation (match with another nearby network), 
    3 – local Wi-Fi network database, based on wardriving activity,
    4 – tentative location based on network name (incl. place or company name).
    Note: The listed distances are just rough information due to nature of Wi-Fi geolocation. They do not correspond to the exact location of a network.
