Funny thing about Wi-Fi, it overlaps with an Amateur radio band (the 2.4GHz spec does) and so hams are allowed to run Wi-Fi with no encryption but a tremendous amount of power and high gain antennas on like the highest channels.

    A portion of the 5GHz WiFI band overlaps with the 5.8GHz ham band too. There are also a few WiFi radios that will also work above the US WiFi band where they can operate without interference from other license free devices. Those are used in the HamWAN network.
