The Extreme Energy Events experiment (EEE), a strategic project of Centro Fermi, aims to study Extensive Air Showers (EAS) with a network of Multigap Resistive Plate Chamber (MRPC) detectors, mainly installed in Italian high schools.
The network presently counts 59 muon telescopes, each composed by three planes of MRPC. The total covered area is more than 3 x 10^5 km^2.
Thanks to the tracking capabilities of these detectors, their time synchronization and the localization in town clusters, it is possible to study Air Showers and to investigate long distance correlations between them.
Up to now 5 long data taking of several months each have been performed, starting in 2015 and simoultaneously involving from 30 to 50 telescopes.
The study of EAS requires excellent performance in terms of time and spatial resolution, efficiency, tracking capability
and long term stability.
In this work, we report a description of the system, its performances and some of the main physics results obtained so far.
