A Day in the Life of an Information Security Officer

I want a satellite phone

Iridium sounds like some sort of chemical or rock or something.  Turns out it's the name of a company selling satellite communication services.  According to this CW article the satellite telephone handsets cost about $1500 with a satellite base station costing around $3000.  That feels a little too rich for my blood personally, but it got me thinking.

We have very little in the way of a communications plan in the event of a local disaster.  Our plan consists of using our own cell phones.  If the power went out and the cell phone batteries died and we could not recharge them, we wouldn't be able to communicate for very long.  Not to mention if the cell towers were knocked out, our communication plan would be dead in the water.  Which is what happened during the Katrina disaster.

Our state agency needs to take a look at this.  I will be forwarding the information to other agencies within our state government to see if we can get some sort of dialogue going.  My only concern about LEO satellite communications is that atmospheric interference can be a problem.  It's definitely an option, but I think the interference issues need to be addressed.

What People Are Saying

Sounds like you need to go

Sounds like you need to go back to the basics. High Frequency (HF) single-sideband radio works as a great backup in disasters. You don't have to worry about the equipment in the middle as you can talk from point A to any point B (anywhere in the world). The military has used this old technology with a few added technology bonuses. That is why amateur radio operators are so valuable during disasters as they use HF quite a bit.

reporters for NPR have been

reporters for NPR have been using these phones to get in stories from locations world wide for a number of years. I'm not sure if they use a compression method or device to get a higher bandwidth than "normal" or if the quality is better than a normal telephone out of the box - but it's not easy to tell when a reporter is remote.

If I remember correctly, the atmospheric problem is when you are pointing into/near the sun to get to the sattelite - which happens for a few hours 2 times a year. If they had a problem in the rain or snow, I've never heard of it.

If you'd like me to try, with a little bit of luck, I could get you (C.J. Kelly) the name and/or e-mail address of someone at NPR that could get you usage details from an engineer's perspective.
