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 0.3% of all networks logged ever. The following list contains only networks received with no LOS at a distance of ≥100 km.
