I went to the NGO to see if there any further technical specifications to read about, it doesn't seem so: https://www.acs-italia.it/gazaweb-e-gli-alberi-della-rete/

it seems to be purely built upon cellular connectivity and hotspots!

I'm shocked there's no meshnet stuff involved here, but I suppose we can't see much details beyond the backbone, last-mile connectivity methods are probably extremely hodgepodge.
