>If they create their own internet in a war torn country, what's our excuse?
Pennsylvania has a law that gives Verizon a right of first refusal to prevent "Municipalities and school districts from being able to compete with regulated phone companies".[1]
heh, poor Jon Katz lost his career in tech journalism after he made up a story about an afghan geek boy who was in touch with the world throughout the Taliban rule via his home made Commodore computer powered by car battery and running linux, or some such. It was the most bizarre lie, totally pandering to the slashdot crowd and the brave new world that was post-911 interweb.
Yeah, but we're only talking about <4km here. Rain fade in the 2.4GHz band could produce up to 2dB of attenuation under flash-flood-thunderstorm conditions. 2dB is not a big deal! At 10km or 20km or 40km you might have a point.
It depends. It doesn't penetrate very far into the trunk, but it doesn't have that much trouble with leaves and twigs. (Until they get rained on.) So you can have a line of sight that's pretty much blocked by trees visually, but quite clear in 2.4GHz.
It's not that simple. Attenuation increases when it rains and the tree gets wet, but whether the attenuation is enough to cut off your connection entirely depends on a lot of things. But sometimes, yes.
If only I had some trash with which to create an Internet. I guess there is a downside to clean living.
What they did is okay, except: "The public hospital, which houses the endpoint of FabFi Afghanistan's longest link, has become a shared community resource, providing downlinks to a growing number of locations in the city center." It's not a good idea to give a major facility a large role in the network, because such a facility represents a big target for the government. It's a good start, but in the long term, any serious attempt at resisting censorship must use the utmost in guerrilla tactics.
The goal is not to get blown up; the government isn't going to try to censor. Plus, the government there isn't monolithic; aside from the NDS, I believe the provincial/city government is much more relevant than the national government, and the FabFi people have done a pretty good job of getting "in" with the local government.
(I've stayed at the guesthouse and climbed the water tower at the hospital where the antennas are installed.)
"... the government isn't going to try to censor."
Um, what? Our own government censors. They unilaterally take away domain names, without due process or even notice, and they create laws which make certain communication, if done in public, illegal, which leads to these crazy Terms of Service that just about every social website has today.
So, GhanStan is full of poppy fields, but the government won't attempt to censor me should I try to cause any kind of trouble with those through online postings? GhanStan is so stable that the hospital should not ever have to worry about its FabFi connection being physically taken down?
The Afghan central government would censor, but has a lot of other issues to worry about, and this is about last on their list.
The local government could try to censor (and, I think has objected to porn and other stuff in the past, which got filtered); the people running it have been proactive in working with the local government.
Not getting blown up is the primary concern here, not government censorship, though. If Afghanistan gets to the point where government censorship is their biggest problem, that's success.
