New Orleans
Can't leave this alone, it is so important to understand where the technology is taking us. It is a cultural issue. A high ranking academic economist, once a consultant to the FCC, questioned the possibility of unregulated WiFi, 802.11 working well in the disaster area where the telephones could not and regulated emergency frequencies were off line. This post, was a response. (Call it the air battle in the information revolution.)

"Tropos has shipped a couple of hundred of our Tropos 5210 mesh routers into MS and LA in the days following the storm, and had a few hundred installed in the stricken area previously.
These are high-power (36 dBm), high rx sensitivity (-100 dBm), outdoor-constructed 802.11b/g access points with embedded mesh routers so they can back-haul wirelessly amongst each other to a source of Internet connectivity. Each has a 1,000 ft plus range to an outdoor Wi-Fi device, emergency vehicle with external antenna or building with a window-mounted CPE. So, a couple of hundred nodes represents 10-15sq mi or so of contiguous coverage in typical configuration. Every 10 nodes or so are fed with a Motorola Canopy "WiMAX" link, typically shot from the roof of an MCI PoP, or from city back-haul locations. These devices, at these densities, are non line of sight so can be installed by city workers with bucket trucks on street lamps, with power taken from street-light photocells. They will self-configure, find their back-haul, optimize throughput and route around problems. They can be battery and solar-powered due to their low wattage (28 watts or so). Last I have heard, we were in 25 or so FEMA and Red Cross shelters in NO, Biloxi, Lamar-Dixon and Baton Rouge. We are around the NO airport and on a couple of cruise ships off the gulf that are housing FEMA workers.
We had 200 nodes previously installed in high-crime areas of NO doing video surveillance. As the power has been restored to the street lights, these nodes have come back up on their own and are performing their functions again. We are now in the process of expanding that network as a "force multiplier" for the police. Data applications as well as Vonage phones and Skype are active on the networks CIO of NO is actually in DC today testifying about the benefits of Wi-Fi mesh. Hope that helps.
