Anonymous' Airchat Aim: Communication Without Need For Phone Or Internet

concertina226 (2447056) writes "Online hacktivist collective Anonymous has announced that it is working on a new tool called Airchat which could allow people to communicate without the need for a phone or an internet connection — using radio waves instead. Anonymous, the amorphous group best known for attacking high profile targets like Sony and the CIA in recent years, said on the project's Github page: 'Airchat is a free communication tool [that] doesn't need internet infrastructure [or] a cell phone network. Instead it relies on any available radio link or device capable of transmitting audio.' Despite the Airchat system being highly involved and too complex for most people in its current form, Anonymous says it has so far used it to play interactive chess games with people at 180 miles away; share pictures and even established encrypted low bandwidth digital voice chats. In order to get Airchat to work, you will need to have a handheld radio transceiver, a laptop running either Windows, Mac OS X or Linux, and be able to install and run several pieces of complex software." And to cleanse yourself of the ads with autoplaying sound, you can visit the GitHub page itself.

CB radio works tens of miles, maybe over 100, with a good directional antenna and that's without "skywave." Highly directional WiFi antennas can give you tens-of-miles communication over "no special license required" frequencies.

    This is a way to have encrypted point-to-point communication or (in some cases) network using any radio (or other) transmission equipment that will transmit/receive audio signals and allow you to tap-into the analog audio circuit of the transmitter and receiver. You could use it with:

    - radio transceivers (legal or illegal - the protocol doesn't *require* that you break the law!)
    - optical communication equipment - free air/fibre

    It just defines a common protocol and means of modulation/demodulation.

    They take a whole lot of words to say this, and throw in a lot of revolutionary rhetoric.

    It's well within the capability of any PC or smartphone today. Although I let my ham license lapse many years ago, I do have a couple of receivers squirreled away somewhere, and a few years ago I experimented with listening-in on amateur packet radio. You just run the output from your receiver into the input of a Soundblaster card (I SAID this was a few years ago...) and the application handles the decoding.

    An interesting side-note: If you're near an airport, you can use similar software to decode VHF ACARS transmissions. (The kind that hasn't helped much in locating MH370). Just install some open-source software, hook your scanner up to your PC, tune to the right frequency, and it turns the squawks into somewhat-readable messages.

    It's biggest drawback is it's biggest strength, IMO. It DOESN'T define a common frequency, some complex frequency-hopping or spread-spectrum scheme, or even common transmission media. It would be extremely hard for it to gain critical mass. On the other hand, it means there are an awful lot of places one would have to look to find it.
