So we have been waiting for mesh networking a long time. The idea is that with mesh networking there will be no need for the internet. If you remember back in the day when the internet had just started AOL had its own 'internet' and you had to leave it to see the actual internet. Mesh networking has the potential to be to the internet what AOL was to ISPs. Meshtastic
We have meshed APs here at the office. Handy to stay on the internet while traveling around the building.
