One option for getting Wi-Fi anywhere is satellite internet. Much like satellite cable on your TV, this involves sending a signal through a modem to a satellite dish, then to an orbiting satellite. The signal is then bounced back to your dish, your modem, and your connected device.
Does a portable WiFi exist?
You can use a portable WiFi router when you travel; whether for business or pleasure, when walking around, at home, in a small office or in the car (there are even special car WiFi devices). You can connect you /your family's /business colleagues devices up to a secure network so you can all get online affordably.
How do I pick up free WiFi from far away?
If you want to connect to your neighbor's wifi, which is a mile away, then the only way to get free internet from that far away is to have a directional antenna with a line of sight, or in layman terms, no barriers in between.
