No mesh network would be able to take the huge amount of traffic involved in such a crisis situation. A mesh network would keel over in all the VoIP traffic alone and even then the dispatch center would be overwhelmed by all the voice traffic. Ricochet performed very well in the post recovery event. I I would use something we can use NOW than build a fictional infastructure that does not exist even in reality. I don't see any 802.11g VoIP handheld radios nor anything remotely close on the market. Lets use what is here now. but true, a billion is a lot. you'd think they could find a slightly more economical way to do it. but as long as the Homeland Security spigot is open, you can expect proposals like these to help make it flow faster into NYC. f you have been paying any attention to what just happened in Washington, Congress just shafted NYC AGAIN for Homeland Security funds. adam On Jun 21, 2004, at 11:38 AM, AdamVazquez wrote: Another refried answer.

[nycwireless] Re: NYC emergency wireless network
Adam, I think you're right. We need solid, redundant, reliable, low-tech solutions for emergency communications. let me take this opportunity to announce the existence of another listserv, run by me for NYU's Center for Catastrophe Preparedness and Response (http://www.nyu.edu/ccpr).

[nycwireless] 802.11i may be ratified tomorrow
1. 802.11i may be ratified tomorrow 802.11i could be ratified as early as Thursday, bolstering WiFi security. The IEEE SA standards committee is meeting this week in Piscataway, New Jersey, and even if a vote on the specifications does not take place, the committee will likely decide to end the three-year standards process. The encryption protocol in 802.11i is based on RC4, a stream-based algorithm developed for RSA Security. The task group has been working on the specifications since May 2001. A month ago the committee met to discuss comments on draft specifications 10.0, but only two negative comments were received, and both were rejected. Since the algorithm used in 802.11i is the same as the one used in WPA, firmware upgrades are likely to be available within weeks of the IEEE decision.
