OpenMobileNetwork Location Provider


In the context of the OpenMobileNetwork [1] platform, thousands of measurements have been conducted by smartphone users using the OpenMobileNetwork for Android [2] app. Each measurement comprises an exact GPS location, a list of received WiFi access points as well as the respective signal strength and the current Cell-ID of the mobile network the smartphone is connected to.

To further utilize this measurement data and to create additional value from it, a OpenMobileNetwork Location Provider is to be designed, implemented and evaluated. This location provider is expected to approximate the current location of a user solely based on Cell-ID and visible WiFi access points. The functionality of the created service is to be showcased by an Android app visualizing the results on maps provided by the OpenStreetMap [3].


  • Literature study of existing approaches and alogrithms used for positioning of users via the mobile network
  • Implementation of a RESTful web service
  • Evaluation of solution(s) and comparison against Google API performance
  • Implementation of an Android app visualizing the results as proof of concept


  • Programming and Database skills
  • Know-how about RESTful web services
  • Experience with Android development would be beneficial
