The Mozilla Location Service (MLS) is an open service, which lets devices determine their location based on network infrastructure like Bluetooth beacons, cell towers and WiFi access points. This network based location service complements satellite based navigation systems like A-GPS.

This open service relies on a community of contributors, ranging from individuals collecting data, developers using and innovating on top of the service to organizations sharing information about their infrastructure.
