Dave,
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 backhaul 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 10-15
sq 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 backhaul 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 photo
cells. They will self-configure, find their backhaul, 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.
The CIO of NO is actually in DC today testifying about the benefits of Wi-Fi
mesh.
Hope that helps. You can see more on our technology at www.tropos.com

I'm a bit skeptical about Reed Hundt's broad claims, too. However, I
do know that Tropos and others who have such technology were attempting
to demonstrate the value of their systems post-Katrina, so there almost
certainly was some deployment, given the value to the companies of the
opportunity to show their stuff.
I've cc'ed Ron Sege of Tropos, who may have more direct knowledge and data.
