Jon Brodkin, over at Ars Technica, has an interesting discussion about a paper from some researchers suggesting that we could augment first responder communications efforts by letting them make use of the public's WiFi routers. Basically, if I understand the proposal correctly, if turned on, it would make use of your router to try to form an ad hoc mesh network with other, similar routers in the area that, in theory would only be used by those public safety first responders. It's no secret that there are efforts underway to make sure that emergency personnel have better access to communications spectrum, and this is, at the very least, a creative way of attacking the problem.

The theory is that this doesn't impinge on anyone's security, because it would effectively carve out a separate service on the router, not unlike home WiFi routers that offer up different logins for residents and "guests." Of course, theory and reality aren't always one and the same, and Brodkin reached out to Bruce Schneier who raised his concerns:

“The problems are the same,” Schneier told Ars. “Once you build such a system, you have to build the security to ensure that only the good guys use it. And that's not an easy task. It is far more secure not to have the capabilities in the first place.”

That said, if such a system were purely voluntary, and individuals were able to offer up such connectivity for first responders (or even for anyone else), would that necessarily be so bad? I've been skeptical in the past of attempts to create truly comprehensive mesh networks building on people's home WiFi routers, and there hasn't been much success there. But, perhaps there's something interesting in special use cases, such as one involving first responders. I agree with Schneier that there could be some risks, but I'm not sure how they would be much different than running a basic guest access WiFi network that doesn't involve a password. As long as you're not using that network for sensitive and unencrypted info, it seems like a similar level of risk.

Marcos points us to a story coming out of Brazil, where a guy who had an internet connection with WiFi, and agreed to share that connection with two neighbors is now facing two to four years in jail (Google translation of the original). Not only that but the Brazilian telecom authority ANATEL has seized his computer, modem and router, and have fined him approximately $1,800. They're claiming that sharing his WiFi was "providing an internet service without authorization." The guy is obviously fighting this in court, saying that it's ridiculous to claim that a guy sharing his WiFi should be classified as a regulated service provider...
