Communications Infrastructure No Match for Katrina 483
jfourier writes "In this age of cheap commoditized consumer electronics and advanced mobile technology, why can't all the people of a city make contact during an emergency? Cell phone circuits filled up during 9/11 attacks and in the wake of hurricane Katrina very few victims can make contact with their families, despite the fact that they have all those mobile phones. The Red Cross is looking to deploy satellite equipment to restore communications in affected areas." From the article: "Katrina made landfall in Louisiana early this morning with sustained winds of 145 mph, but veered just enough to the east to spare New Orleans a direct blow. Even so, flooding, power outages and heavy damage to structures were reported throughout the region.
The Red Cross tomorrow expects to begin deploying a host of systems it will need, including satellite telephones, portable satellite dishes, specially equipped communications trucks, high- and low-band radio systems, and generator-powered wireless computer networks, said Jason Wiltrout, a Red Cross network engineer.

They could store them centrally inthe country. Since they usually have a large warning, they could get them nearby the pending storm. Right after the storm clears, instant tower.

"In this hypothetical storm scenario, it is estimated that it would take nine weeks to pump the water out of the city, and only then could assessments begin to determine what buildings were habitable or salvageable. Sewer, water, and the extensive forced drainage pumping systems would be damaged. National authorities would be scrambling to build tent cities to house the hundreds of thousands of refugees unable to return to their homes and without other relocation options." [colorado.edu]

An 85 yr old woman was trapped on a rooftop. She somehow managed to get a cellphone call out to someone in Tulsa, OK. From there, the Red Cross took it, and asked for HAM assistance. From there, the message was relayed by ham ops to Idaho, then to Utah, then to [somewhere else], then down to the Coast Guard in Mobile, AL.
She was rescued.

If you could combine this concept with a wind power generator, you could have more a resilient network - Suppose cell phone towers could have a wind speed monitor and shutdown if the wind speed exceeded a certain limit, rather than wait to be knocked down in a blizzard or a storm?

You CAN still be held liable for the consequences of your actions after the fact. There were a couple of similar cases I read about where a guy out hiking got lost in the mountains and there was no cell service or any ham station reachable, and he used his modified radio to call into the local police repeater to report his emergency. Clearly he would have died if he had not been rescued, yet he was still fined and had his equipment confiscated because of his actions.
In short, if you are faced with the decision of losing your Ham license or dying, you'll take the former, but as I said you will most likely have to pay the piper later.
BTW - Yes, IAAH (I Am a Ham) and I'm the statewide repeater frequency coordinator for one of the largest metro areas in the USA, so I speak with some authority here.

There is also some karma in play here that an intense hurricane which was probably intensified by CO2 induced global warming, thanks to abnormally warm temperatures in the Atlantic and Gulf, would lead to devastation in Louisiana which is at the heart of the oil and gas part of the fossil fuel industry in the U.S. and is responsible for much of America's CO2 pollution capacity.

It seems that you can get one or two watts of transmitter to go amazing distances if you know a little antennae theory and know how to lay your hands on a reel of coax cable.
Long-wires, capacity hats, incredible things like directional-discontinuity ring radiators, very high tech that can be built with a few iron fence stakes and a bit of wire and a good head for geometry.
Astoundingly powerful communications technology for an extremely accessible cost. If you want to know more get an old ARRL handbook. Sort of like the older Boy Scout Handbooks from back in the days when they were useful, but cover all the basics of home-brew transmitters. Get one.
One of the problems ham radio faces in times of cataclysmic storm is the shape of the ionosphere at the time and place. It's used as a signal reflector. On good days you can whisper from Maine to Tokyo on a watt. On bad days, you can't punch through with 50MW unless you have line of sight.

This is a good reason that the cellular companies need to re-instate the Local Access Numbers (or Roamer Access Numbers depending who you ask)
It's the system that was used when all the local cellular systems were independant. If you were roaming, people had to know where you were and call a phone number there. They would then enter your phone number (MIN) and your cellular phone would ring.
I continued using the system for quite some time after roaming call delivery was implemented. It was a handy way for people from the area you were in to call you without you or them having to pay long distance fees. (After the so called follow-me roaming was implemented, I would get calls from people where I was, paying long distance to my home area, while I was paying long distance from my home area. This was before everyone had free long distance)
