OpenCellID is a collaborative community project that collects GPS positions of cell towers and their corresponding location area identity. More than 49,000 contributors are registered with OpenCellID, contributing more than 1 million new measurements every day on average to the OpenCellID database. As of August 21, 2017 the database contained 35.5 million unique cells and 2.1 billion unique measurements. OpenCellID publishes an aggregate data set of cell locations licensed under a

Applications

Data on Cell IDs and their locations can be used to provide location information to mobile devices. Using Cell ID locations to find device location is more power efficient and often faster than using satellite-based navigation systems, although it is less precise because of the lack of known Cell IDs. The database is also used to determine the strength of available wireless connections and which mobile phone service providers have coverage in specific geographic locations.

Data sources

The unique location area identities of the cell towers can be collected by devices that utilize the wireless network provided by those cell towers. This data is primarily contributed by
