​AREDN Donates Mesh Networking Equipment to ARRL

 

High-Speed Multimedia Mesh (HSMM) technology has evolved rapidly in recent years due to the development efforts of the Amateur Radio Emergency Data Network (AREDN) open source project. This has changed the complexion of mesh implementations from an experimental, hobby-oriented, novelty into a viable alternative network suitable for supporting high-speed emergency communications and Internet connectivity when “all else fails.”

The AREDN project team recently donated the following equipment to the ARRL Laboratory:

  • Two Ubiquiti Nanostation M3’s for 3.4 GHz
  • Two Ubiquiti Nanostation Loco M5’s for 5.8 GHz
  • One PowerBeam PBE-M5-300-ISO for 5.8 GHz
  • One AirRouter HP (combination 2.4 GHz and Ethernet switch)

The AREDN (pronounced “r-den”) project is working with ARRL, the national association for Amateur Radio to inform the amateur radio community about this high-speed, low-cost networking technology. To further our shared goal of supporting emergency responders, AREDN has donated a substantial kit of mesh networking equipment to the ARRL for their familiarization and deployment. Both groups plan to work together to provide written guidance on the best practices for using this networking capability to provide such services as voice-over-IP telephony (VoIP), streaming video, email, and much more.

​Hamvention® 2018 Theme Promotes Community Service


As reported by the ARRL, the theme for Hamvention® 2018 is “Amateur Radio...Serving the Community.” Ron Cramer, KD8ENJ, Hamvention General Chairman, said the theme acknowledges the role that ham radio operators play in their communities, especially in times of emergencies.
 
“During recent disasters, hurricanes in Florida, Texas and Puerto Rico and wildfires in the West, Amateur Radio operators were once again called upon to provide emergency communication assistance when regular services failed or were overtaxed,” Cramer said.
 
He said that in keeping with the theme, Hamvention is planning to have forums on emergency communication and displays of Amateur Radio emergency communication vehicles. Disasters are not the only times that Amateur Radio operators contribute to their communities. 

For more information see the Hamvention website and the ARRL website.

Look for the AREDN team and the Miami Valley Mesh Alliance when you are there. We look forward to meeting you.

Nightly Builds Are Easier to Find

We have added a menu item under Software for the Nightly Builds The should make it easier to find the latest AREDN firmware.

Remember that these versions may have instabilities or bugs.
Our progress depends on community feedback, so please report all your results, both positive and negative, from using a nightly build.

Before downloading and installing a nightly build, please read the README and CHANGELOG files. We cannot emphasize this too much. 

 


Map and Firmware Download Links Updated


We have updated the Map display page with a link to show the node location data we have on file.  Click HERE to view the live map (in a new tab/window)  

The Downloads page is updated with a link to get the AREDN firmware. Click HERE for downloads 
New nightly builds are available from this link.

The ability to upload a node's latitude and longitude to the AREDN Map server is temporarily turned off. We are working on a fix and expect to have it released shortly.

 

Operational Notes for AREDN™ 3.0.2

 

Inter-mesh Tunneling

VTUN can be real useful in connecting mesh islands across non-mesh networks, such as the Internet or other private IP networks.

For instructions on setup and configuration, see the article on AREDNMesh.org

Additional things to remember when using tunnels:

  • The OLSR protocol runs over the tunnel, so mesh networks on the other end of the tunnel appear to be directly connected to your local mesh.
  • Only the Client or Server may be installed on any given node.
  • Nodes still running 3.0.0 which are connected via RF to a tunnel server or client may not be able to access the Internet at their local node unless they update to 3.0.2.
  • Internet gateway traffic across the tunnel is blocked by design.   It is a decision for the local mesh Administrators to coordinate if it is appropriate or not for their local users to have an advertised internet gateway.   A tunnel, if the only path of connection, may be used to divide nodes on a mesh and isolate who has and does not have Internet access.   To avoid routing failures, if a given...

​AREDN Will Implement TLS on Website


The AREDN Project plans to enable mandatory use of transport layer security (TLS) on the AREDNMesh.org website starting Wednesday, September 13.  TLS is an encryption technology that obscures the meaning of the website traffic to 3rd parties. We are doing this to better serve our community and to avoid being labeled a potentially harmful website by ever increasingly strict search engines and browsers.

You should know that accessing the AREDN website with TLS over an amateur radio link may be considered a violation of FCC Part 97 regulations. 


​Hamvention 2018 Initial Report


This brief note is just to let youknow that all of us in the AREDN booth had a great time meeting hundreds of people in Xenia, Ohio. I am still a bit tired after al the activity, dismantling the booth, packimg the gearand driving 10hours back to New Jersey. So please be patient and I will have a fuller recap of our activities there soon.

A very special thank you goes to the members of the Miami Valley Mesh Alliance, and Markand Karen Herson, who so ably told the story of why an AREDN mesh network is so effective and how to use u=it for a variety of practical purposes.

Excuse me while I start to get the truck unpacked,
Randy WU2S
