# Wifi Geoloc

Thanks to the contributor and the SDK embedded in partner apps, we've built up a huge database of Wi-Fi MAC addresses associated with their location, completely anonymously of course!

Our Wi-Fi hotspot-based geolocation service uses the MAC (Media Access Control) addresses of the Wi-Fi access points in our database to determine a device's geographical position. When a device (such as a smart device) has a Wi-Fi scan function, it can scan and detect signals from surrounding Wi-Fi networks. Each Wi-Fi access point emits a signal containing a unique MAC address. The geolocation service collects these MAC addresses and compares them with our database, which associates each MAC address with specific geographic coordinates. By comparing the detected MAC addresses with the data in the database, the service can triangulate the exact position of the device with variable accuracy, often sufficient for common uses such as indoor navigation, shopping mall location services, or position-based recommendations. This process is effective even in the absence of GPS signals, making geolocation possible inside buildings where GPS may be unreliable.
