Microsoft Q&A on Location Data
by Volker Weber
How does Microsoft provide location services?
To provide location services, Microsoft assembles and maintains a database that records the location of certain mobile cell towers and Wi-Fi access points. These data points are used to calculate and provide an approximate location of the user's device by comparing the Wi-Fi access points and cell towers that a user's device can detect to the location database, which contains correlations of known Wi-Fi access points and cell towers to observed latitudes and longitudes.
