well tbh, there are places on earth where there are no regulations on frequencies. Those are the best spot to start meshnet. Once people see it’s true potential, they’ll do it in their countries, and godvernment can’ do anything about it but harass people.
However, I think the best goal is to build a fiber meshnet. No radio frequencies needed. We just need to reroute to homes to homes, instead of home to central ISP. Fiber is getting cheaper by the day.
Edited: I forgot to mention that mesh net should be used with wifi routers. I don’t see the need of high end frequencies if you can connect to your neighbor? The only thing I see of needing it is when it needs to connect to another city.
