Configuring Situm technology in a building requires to capture the signal data (WiFi, BLE...) of all the areas where we want to provide indoor positioning.  

Calibrating (or fingerprinting) is the process of recording those signals. In order to do this, an user has to walk around the building, pinpointing where he is every few meters using our Situm Mapping Tool application.  

A calibration is therefore each of these signal records that the user captures. The following image shows an example where the user has calibrated a corridor of a building, captureing WiFi and BLE signals.

With this information, we train the positioning model: the electromagnetic signal maps of the building. After the positioning model is built, each smartphone that contains the Situm SDK will be able to match the signals received with those in the model, in order to estimate the location accuratelly.
