- An introductory presentation of the AREDN Project and a high-level "how to" on designing a wide-area mesh for restoring Inter/intra data-networking during disasters when primary network infrastructure has failed. See AREDN.org for more information.
Merry Christmas from Dennis KJ6RSU
Hey Andre, thanks for a great video. I've a couple of questions, first some backdrop. I'd like to stir up some interest in east Dallas. Problem being that this area has mature pecan and oak trees. I want to reach out to east Dallas hams but would like to have an idea on how we could organize first.
So, first question: With the trees, will we have to have line of sight, clear of leaves and branches? This question for all bands, including 900 mHz? Or, is it possible at a certain distance to get through branches and leaves with a directed antenna and short dx? In east Dallas there's a lot of hams, so it's possible we could get some density too. What would you recommend?
Second question - just curious is all - I have some networking background - in terms of your description and graphic about OLSR... Does each and every device hold a table in memory with cost of each path? Does OLSR run on every device, including the smaller 802.11n clients? And then if A-B is broken, does it stop transmitting those packets on that route and just then begin a transmission to A-C? In other words, the RF part of this is IP smart and doesn't transmit unless the route is active with interesting traffic?
Thanks again and 73

Hi Patrick,
Check out other hams in your area with this link and find out how you can integrate with them: usercontent.aredn.org/K/5/K5DLQ/livemap.html
The other questions are better addressed in our forum. I encourage you to sign-up and post them for everyone's benefit: www.aredn.org/
Andre, K6AH
Andre, there's no mesh anywhere near me, according to your map and also the HSMM Dallas map. I am planning on reaching out to the hams near me for possible organization - however, was wanting some basics first. Ok, I'll check the site you suggested.
We've played around with BBHN a bit around here. We recently decided to give BBHN another go. Someone mentioned AREDN on our yahoo group. This looks pretty awesome. The ubiquity hardware looks pretty amazing. Right now all I have is some linksys routers with BBHN. I may have to pick up a ubiquity device to play with. Since we already have a number of BBHN enabled linksys routers. I was thinking it might be good to use those for small meshes and use AREDN for for longer haul connections between those mesh pockets.

Hi Jennifer,
You have AREDN implementations coming at you from the East Bay and also the Merced/Modesto area. Check out the map which currently represents only a small fraction of active nodes:

+Andre Hansen Thanks for the info I will pass it on to the other folks at the LIvermore Amateur Radio Klub.

Well done. Is there a website for parts and smarts to get one set up? KK6OUX, in San Diego

You can check out AREDN.org for more information and a list of compatible devices. A Google search of the model names will identify a variety of sources. Note the a Ham Radio Technician license or higher is required to operate them with the AREDN software.
Thank you, looking to learn more about AREDN I was having trouble viewing the web books on the site but will keep trying.
+Patrick Knighton I didn't realize you were in the San Diego area. There is a high-speed AREDN backbone node on Mt. Otay, not far from you. Contact me on callsign@arrl.net and we'll get you connected to the San Diego AREDN Mesh. We also have monthly meetings in Del Mar the 2nd Monday of the month.
Well done looking for Westchester County NY interest
thanks for the post. i would certainly want to introduce this into Singapore and work with the ham community in 9v1 land. 73s de 9V1HP
a tip : you can watch movies at Flixzone. Been using it for watching lots of of movies recently.
@Phillip Manuel Definitely, been using Flixzone} for since november myself =)
sir how i get the SNR value using linux command line

SNMP, is this the 1990s or something? Save your time and give it a rest apt.
What's your alternative? Why would SNMP traps be a bad idea? If your building a network from scratch, what sort of expectations should one have?
@@FourtyParsecs Nothing wrong with SNMP lol
