I was under the impression they were scrambling to get temporary towers
up and running; meanwhile, wimax tests are going on in San Antonio:

I imagine that this won't work if the Verizon cell towers in the area
have been detroyed. You'd also have limited bandwidth to share, though
that's less of a concern. It's a stellar idea in general, though.
Cheers,

How to make a solar powered backpack wifi hotspot</i><br>Date: <i>Fri,
09 Sep 2005 12:47:47 -0400</i><br><br>A month or so ago, Popular
Science had an article on how to make a mobile wifi hotspot in a
backpack. At the time it was published as just an uber-cool way for
geeks with a little extra cash to show off their tech props. Given all
that's been going on with Katrina, though, I wanted to relay the
basics of the instructions here so that people on the ground would be
able to implement their own mobile hotspots as wireless broadband goes
back online along the Gulf Coast. The whole thing can be set up for
around $1,100, but I imagine it'd be worth it for orgs working on the
ground trying to maintain communications from the field. For the full
details, please see the original
article:<br><br>http://tinyurl.com/ceyud<br><br>Ingredients:<br><br>•
Junxion Box wireless gateway $700; junxionbox.com<br>• Verizon
Wireless EV-DO PCMCIA card $100; verizonwireless.com<br>• Voltaic
Systems solar-charging backpack $230; voltaicsystems.com<br>• 12-volt
battery with spade terminals, 1.2 or higher amp-hour $15<br>• Male DC
power plug, size M $5<br>• 18-gauge wire, black and red $5<br>• Female
insulated quick-disconnect connectors, crimp-type, sized for battery
spade terminals $3<br>• In-line fuse holder $7<br>• 20-amp fuse 50
cents<br><br>Instructions:<br><br>1) Plug in your EV-DO card and set
up the Junxion Box to automatically assign TCP/IP addresses using
DHCP, and disable the authentication splash page.<br><br>2) To build
the power-adapter cable, cut a length of red wire and a length of
black. Strip one end of each wire and crimp a spade terminal connector
onto each.<br><br>Strip the other end of the red wire, and solder it
to one end of the fuse holder. Wrap the connection in electrical tape.
Take apart the male DC power plug. Solder the end of the black wire to
the negative terminal of the plug and the red wire to the positive.
Wrap the exposed positive connection in electrical tape, and
reassemble the power plug. Install a 20-amp fuse.<br><br>3) Connect
the Junxion Box cigarette-lighter adapter to the backpack “power out”
plug.<br><br>4) Connect the battery cable to the “battery” plug on the
backpack’s charge controller.<br><br>5) Take a hike - you're ready to
go.<br><br>--<br>-----------------------------------<br>Andy
