Tinitell uses GPS, cell tower triangulation and wifi to provide a good location indoors and outdoors. It has a GPS module incorporated and GPS is used as the primary localisation system.
As the map and the GPS module are not incorporated in the same device (the map is on your smartphone) Tinitell needs data services to transmit its location to the app.
Based on our latest analysis, Tinitell needs on average 50 - 100 MB of data per month. We are constantly improving the localisation algorithm and optimising the frequency in transmitting the data, so as to reduce the data consumption.
