I hate to sound like a paranoid delusional, but this is a time when having even a basic amateur radio license seems like a really great idea. It's not impossible to for the government to shut down the airwaves, but it is a lot harder to do it on a broad scale. Communication is essential to a free society, and it's startling to me that our government wants the same ability. It seems so entirely counter to our core principles as a nation.

Never has it been more clear that blocking free expression is the primary tool of tyrants to prevent change and reform within their society.

  It's less clear than you think. It didn't work in Iran and it might not work here. The arrogance in social media will have to be reconciled with failed revolutions.

  On the other hand, it may temporarily solve the ipv4 address exhaustion issue

    Temporarily, IPv4 exhaustion is not a problem anyway. It is a long-term problem.

  I really hope that's what it will end up being. But I fear that the actual end result will be an Egypt ruled by one of the Muslim extremist groups that operate there and which are far more organized and poised to take advantage of a power vacuum.

Another excellent example on why it is utterly important that we develop open-source GSM tools, both software & hardware.

  So OpenBTS is doing a reasonable job on the base-station side, at least for small call volumes: http://openbts.sourceforge.net/ http://openbts.sourceforge.net/ Does anyone know of an open-source stack for handsets?

    There's osmocomBB. and there was openmoko but development stopped in '09...

  The problem is, running something like this would be a) illegal due to frequency problems and b) if we leave aside the legal implications, you might be killing valid emergency service calls. That said I think it's excellent for the direction of future telco developments.
  - erikabele 16y ago
    Egypt did shut-down mobile networks, right? So you'd be enabling emergency calls! And re illegal: if you start burning cars in the streets then I'd argue that running an 'illegal' base-station is one of your minor problems...

    I think someone should start a Kickstarter site where weatherized mobile base stations are developed from off the shelf parts, such that they can be quickly assembled, packaged, and shipped to neighboring countries where there is a totalitarian Internet blackout, so they can be smuggled across the border. Even IM, SMS, and small still images are a threat to such regimes, especially in times like this.

I seem to be posting this a fair bit recently: * http://www.villagetelco.org/ http://www.villagetelco.org/ * http://www.open-mesh.org/ http://www.open-mesh.org/ But yes, I've been considering getting one on and off for 12 years. Sadly data over amateur radio doesn't appear to have progressed much in that time. Still, as voice comms it's pretty solid! Some countries UHF radio is still very popular (e.g. Australia).

  It depends what you mean about progress. Digital communications evolved and it's nice to have data capability that can span the globe with a 100W radio (PSK shortwave). The bandwidth is not there, unless you go up in frequency, but then the range is limited without repeaters. I ran a VHF AX.25 node for a long time, using a 486 linux machine and soundcard as modem. With a good antenna and location I had people connecting from 50km or more and with my internet connectivity some even used tcp/ip. I could also connect to other nodes, using my peers as repeaters. My point is although the communication is slow, it's very easy to get something going with cheap radios (mine was a used modified radio from commercial frequencies), homebuilt antennas , computers that nobody wants anymore and of course open source.
  - Swannie 16y ago
    Getting quite OT here. I was looking at building a AX.25 node 10 years ago, with a 15km range on a basic amateur license, with maybe 28kbps. Almost all integrated into a radio with a digital output that cost the same as a PC. That's what I mean about lack of progress... not much advanced today - it's a bit cheaper and easier, with better range, but no better bandwidth. If the frequencies & range are a fundamental issue, OK. When I was reading 10 years ago there was a strong dis-interest in data from my local groups, who thought it was ruining their voice comms. Still today I find the local amateur radio groups have little interest in packet radio beyond maybe running a webcam over AX.25. The interested HAMs are running community WiFi projects.

It seems kind of ironic to have to get a license to get around services the government might shut down.
- sfphotoarts 16y ago
  you only need a license to broadcast legally, if you're trying to over-throw a government, it would seem unlikely that you'd be too worried about doing it legally. HAM radio is interesting, because it is the most decentralized form of communications. Cell phones are internet and land lines are all routed through some corporation or government entity. HAM radio relies only on RF propagation. Repeaters are another matter, they can be knocked out, but a decent HF tx will get you a good distance.

There are apparently some renegade hackers running HAM radio out of egypt. Apparently theyre sending morse code back and forth. http://werebuild.eu/wiki/Egypt/Main_Page#Hamradio http://werebuild.eu/wiki/Egypt/Main_Page#Hamradio "40m band, ~7-7.3 MHz LSB, 318.5 degrees(northwest/north from cairo), Friday night until the morning (16:00-05:00 UTC). ON/KC0SJH will be calling CQ" They also seem to be coordinating free dialup links. Biggup.

  It'd be good if they could setup a digital packet system instead. On lots of frequencies to prevent jamming. http://en.wikipedia.org/wiki/Packet_radio http://en.wikipedia.org/wiki/Packet_radio

it's not impossible to for the government to shut down the airwaves, but it is a lot harder to do it on a broad scale it's trivial to jam most ham frequencies.
- kgermino 16y ago
  But is it trivial to jam most ham frequencies across the 3.8 Million Sq. Miles of the U.S.? Or Europe (Same Size)? Or even just Germany (135,000 sq. miles)? Edit: For comparison Egypt is about 387,000 sq miles. I realize that you would not have to cover the entire country to be effective, but probably at least 90% of residential areas. Especially in Europe where the radio operators only need to reach over a nearby border.
  - joubert 16y ago
    You probably only need to isolate the most populous centers.

    I'm not a ham, but I'm sure this thingie http://www.iritel.com/iritel/latinica/proizvodi/radio%2520komunikacije/pdf/HF_J-e.pdf http://www.iritel.com/iritel/latinica/proizvodi/radio%2520ko... will cover very sizable area without a problem.
