How do MicroG geolocation modules work?

MicroG services come built in iodéOS. They are an open-source & privacy-friendly re-implementation of the Google Play Services.
One of these services allows you to choose Google’s alternative location modules. Location modules allow your iodé phone to be located based on network infrastructures such as bluetooth beacons, cellular antennas, Wi-Fi networks and your GPS coordinates. Feel free to change the one by default with an other.
