Ask HN: Effective and low cost way to share WiFi with nearby low income areas

hi! i come from a relatively privileged family and i think with all the internet progress made so far (good quality learning ecosystem from YT/ courses/ etc + advanced knowledge curation from search engines/ LLMs, etc.) over and above the infrastructure layer we're still lagging behind on democratizing of affordable infrastructure/ transport layer (home internet connections). Given its the backbone for connecting with world and enables one to extract knowledge, failure to democratize its access is regressive imo.

In my country most people from lower income strata use mobile data (~1GB per day) which may not be enough for a family of 4 with education needs, entertainment needs, etc. All these needs are important if we want them to sooner merge with mainstream society. More importantly, I sternly believe having diverse exposures to varied dimensions of society can come from increased travel and/or from immersing in different cultures (exposure from good foreign entertainment content - Netflix/ and the likes, e-books, etc.).

Therefore, i want to start a side project to democratize underlying transport layer with support from community - basically leverage existing home wifi networks and extend them to nearby low income areas for free to use.

However, i'm not sure on whats the best way to approach it technically - mesh networks? access points?

Also, don't think antenna's with 5g/4g is possible given regulatory permissions required.

Wanted to discuss and get your views on how such a project be undertaken, as well as, any learnings from past similar if undertaken by anyone.

Thanks!
