Engineering:OpenCelliD
OpenCelliD is a collaborative community project that collects GPS positions of cell towers and their corresponding location area identity.
OpenCelliD publishes an aggregate data set of cell locations licensed under a Creative Commons Attribution-ShareAlike 4.0 International License with the intention of promoting free use and redistribution of the data.
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[1] than using satellite-based navigation systems, although it is less precise because of the lack of known Cell IDs.[2] 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.[citation needed]
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.[3] This data is primarily contributed by smartphone users who have installed apps, such as OpenCelliD[4] or OpenCelliD Client,[5] and commercial tracking devices such as blackboxes, but also by wholesale data donation by corporations. This is then collected and transferred into the OpenCelliD API database.[6]
