An independent Internet

topic posted Mon, December 4, 2006 - 7:29 AM by  B


I m concerned that the Internet is controlled by large corporate interests with easy access by the US gov. (attacking the main name servers and all). I believe that an independent internet based of low power radio links between computers is possible. This would be a new and totally different protocol very much related to TCP/IP but with added features and security. Maybe every packet PGP encoded with the exception of routing information. When the crash comes we can still have an form of Internet communications and data sharing one that is free from gov snooping as well. Oh my.

I would like to hear comments and constructive criticism. My rf design is very rusty and all comments on the radio portion would be welcome.

    Such would be possible as a local thing but not globally.

    Internet signals are either directly cabled things or sent by very, very high frequencies. Short wave radio could probabnly carry a single channel of straight e-mail. AM radio could only do that slowly. As an example. During WWII, Germany and Japan were communicationing using a system of ultra low frequency sent following the surface of the World's oceans. The Allies never figuered it out until after the war. But this low a frequency couldn't even handle voice transmission, only slowly sent morse code. For packet switching info like is sent on the Internet you need very high frequencies but these are stricly line of sight, like ground to satelite. Global communication by radio is possible, of course, but never at a level like used on the Internet today.

      The term you are really looking for is bandwidth. And it has a direct correlation to carrier frequency. There are several ways to achieve high bandwidth. High frequency such as light modulation and fiber optics or lower frequency and multiple channels like a bundle of coax or multiple channels of rf. One of the major bottlenecks of the current Internet is the backbone and the need for very high speed routers. Now if the dependence on a few backbones could be eliminated then higher speed could be achieve. Possibly at the expense of point to point delay. So high throughput but higher delay as well.

      Your point about global communications is well taken that is something that is an Achilles heel. Anything that has the rf reach can be taken out with a well placed missile.
