Wow this actually sounds like a bloody brilliant idea here. I do have some questions though I hope you can answer!
How is it possible to have random people connected to your public Wi-Fi, how will this be secure?
Does this mean to say that people from well outside your WiFi range can connect to your Wifi somehow? Or am i misunderstanding this?
A global decentralized WiFi network is created by community efforts. Any router, even yours can participate in our system. The range of WiFi matches the range of the router that distributes this WiFi. As for security, the connection is absolutely safe. Preliminary testing showed excellent results.
