Can we redesign WIFI waves from too short to longer waves that can reach around the world like HAM radio? Is WIFI regulated by the federal government of the United States and maybe by other countries too? Does WIFI have patents or something? Like copyrights? If that is a problem, then can people invent open source systems that are not regulated? If a radio can send a long wave, then why are computer routers not doing the same thing? I would call it blockchain WIFI.

If you had 2 computers, one in Texas and one in India, would you know how to remote access the one computer from the other computer using maybe whatever you have to use to send long wave HAM radio signals or through other methods?
