I think same goes with Germany, and maybe Spain as well. Chaos Computer Club is famous, but guifi.net[1] deserves to known more (than it currently is)!
> Guifi.net is a free, open and neutral, mostly wireless telecommunicationscommunity network, with over 33,000 active nodes and about 46,000 km of wireless links (as of April 2017). The majority of these nodes are located in Catalonia and the Valencian Community, in Spain. but the network is growing in other parts of the world. The network is self-organized and operated by the users using unlicensed wireless links and open optical fibre links.
> The nodes of the network are contributed by individuals, companies and administrations that freely connect to an open network of telecommunications and extend the network wherever the infrastructure and content might not otherwise be accessible. Nodes join the network following the self-provision model since the whole structure is explicitly open to facilitate understanding how it is structured, so that everyone can create new sections as required. That results in an network infrastructure commons that provides abundant connectivity.
