Sigfox Geolocation, the simplest and most efficient IoT location service. Sigfox Geolocation is a low-energy location service for all devices equipped with the simplest Sigfox module, without GPS. There is no need to retrofit to upgrade specific hardware, or to update software: Sigfox can now provide a location for all existing and future devices all over the world.
The location computation is based on the data from the Sigfox infrastructure, coming from several replicas of the same messages sent by a device and received by different base stations.
The method used is not based on flight time or signal Doppler shift, but on the signal strength (RSSI - Received Signal Stren- gth Indicator) using a probability model (the location with the highest probability is selected).
The Sigfox Geolocation service will evolve in 2017 to increase its accuracy by using Machine Learning technology.
