mesh nodes are these usefull for emcoms?	Reply

came across this site and was wondering if this would have some utility as an emergency communications mode, after reading some of the explanations on how this works i thought it might be a way of establishing a wireless WAN with minimal infrastructure. brought this here as i am sure that some folks here would have the expertise to explain and advise on how this would work, how easy it would be to set up and run. http://www.instructables.com/id/Mobile-Emergency-Communications%3a-Mobile-Repeater-a/ alex

It can't hurt, but presupposes there's a wireless access point still working within a few miles. That's a very big if. The Red Cross Disaster Services Technology teams have a number of vehicles, trailers and fly away kits designed to be deployed to a disaster relief operation headquarters. By providing internet access via satellite link, the disaster headquarters then has computer capabilities and VOIP phones. If you're interested in doing this sort of thing on an organized basis, contact your local Red Cross chapter and talk to the emergency services coordinator. Tell him/her that you're interested in becoming a Disaster Services Technology volunteer in DSHR. 73 Gary, K2GW

They can be useful for range extension IF you can find channel(s) which are not overly-congested. Big if in some areas. I've been buying Ubiquiti Networks stuff for a while now. Less expensive and innovative products which are pretty well-supported by the open-source community. I like the basic concept of what they were doing in that website (the packaging is pretty nice), but IMHO, there are less expensive alternatives than Soekris boards. 73s, john W3JKS/AAT3BF/AAM3EDE/AAA9SL (I've been building web pages on some of our projects at http://www.armymars.net/ArmyMARS/MCU/index.html, but I'm way behind on getting all of it converted from hand-written notes and diagrams into HTML. Sometimes its hard teaching old engineers new tricks. :-))
