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 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 (like 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.

Note: During normal conditions up to around 700 networks can be received with my current setup.

For more information see the statistical charts.

4. Indoor consumer Wi-Fi routers

Under very good propagation conditions it is also possible to receive signals from indoor devices at long distances. Reception from indoor devices is very rare. This is around 0.15% of all networks logged ever. The following list contains only networks received with no LOS at a distance of ≥100 km.
