There are a few wifi projects, but the most promising is IUNGO if you are interested in this technology.

I found them here, in the forum a few weeks ago and today they are on Coinspeaker https://www.coinspeaker.com/2017/11/11/everything-amazing-everyone-happy/

At a very high level, Iungo provides society with ubiquitous and seamless internet access through a distributed global network, built upon a swarm of  wifi hotspots.
