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,
Charlie

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
backpacks charge controller.<br><br>5) Take a hike - you're ready to
go.<br><br>--<br>-----------------------------------<br>Andy
