Hi Everyone,
                   Thanks for joining in.  My job for 32 years was responding to emergencies.  I knew how to operate my radios properly, and that's where my comm.'s knowledge ends.  With the CAC teams communications will be vital.  Please work from the premise that we will be operating in areas with no power and no cell phones, we will be totally self sufficient in the comm.'s arena.  Also, if we are able to provide cell phone signals to the disaster victims at some point in time it would be a big plus.  We see our needs as multichannel local comm.'s for team members on scene, mid range comm.'s (say up to 50? miles) for recon teams, and national comm.'s to communicate with a central dispatcher.  We would also need the ability to communicate with disaster victims who may be seeking help using FRS-GMRS, CB, or Ham.  Naturally, the terrain will change with every deployment.  Blue sky ideas are always welcome ( you never know when someone will donate $500 million) but for now we should plan on equipment that our average communications team members would already have or could be reasonably purchased.

Thanks for joining in we truly appreciate your help.

Stay safe and enjoy

If you want to go with Blue Sky Ideas -

Modified 20' SeaPak

* 5kw Generator
* 40-60' Fold down Crank up tower
* WiFi hot spot with beam link - Mesh network
* Weather station
* Video camera on tower
* Repeater - commercial and alternate
* GPS beacon
If you want to do at a Ham operator level, cost s will always be a issue.  But it can be done.  I operated a 2m station for a bike race years ago with a Radio Shack Push up pole (38'), a Kenwood TM-241 and a car battery.  Was hitting the repeater from almost 60miles out on a home made beam.

Problem with communicating with the average person running GMRS or FRS is the shear number of people trying to use a single channel.  One person may not be able to monitor all that.  You MAY want to have some means of recording all voice and digital communications...

As for providing cell phone signal to people - You'd have to work with the carriers on that..  There are few if any private means to do so.  Most carrier towers are already in place with battery backup and generators...  and many have rapid deploy-able rigs for spots.

Thanks for the reply idelphic.  Through my own fault approximately 90% of your reply is Greek to me.  What we really need is about 10 more people like you to get this discussion going and to come up with some communications plan for us.  So if you have some comm savvy friends invite them over here and let's work on this.  In the mean time I would appreciate it if you would explain some of the things in your post to me, beginning with the wi-fi hot spot (which I think I understand) but the beam link-Mesh network has me baffled.

Again, thanks for the post and the help.

Beam link may not be a 'true term' but it worked in my mind when I was typing my reply.  Nuts and Bolts is that it's a directional antenna with only one purpose.  Connection to either a sourcing point of the internet (X)miles away.  It's the feed for the local node.

Mesh Network is a type of 'self healing' wireless and wired network.  If you have 5 points or 5 'Pods' then each pod has a minimum of 2 connection, but generally 5, so five x five is 25 interconnects. 

In the image above, if node 6 were to go down (power, etc) then the network continues to function by routing information via the other nodes.

A larger sample is a Cellular system...  You have towers everywhere,..  and you drive past them, your call or texts are routed via the closest tower into the system and handled by the server to be sent on.

OK idelphic now that's an explanation that I can understand  :)  It also happens to be one of the ideas that has really appealed to us.  Now some questions.  How doable is it?  How close to the sourcing point would this have to be?  Would we have to be the sourcing point?  Ball park guess $500 million or somewhat less?

Again thanks, you're a big help
