Link Quality Manager (LQM)

 

Thanks to recent developments by Tim KN6PLV, we are introducing a new tool to help manage AREDN networks.

Nightly Build 1265 contains a number of improvements broadly called Link Quality Management. It’s designed to make the AREDN network more stable and improve the available bandwidth. Tests with these changes have shown improvements from modest to close to 200% in link throughput, tested end to end with iperf3.

Documentation is here

Nightly Build Reminder

The AREDN team greatly appreciates all of the testing of the nightly builds as they roll out and introduce the new code base and features. We are paying close attention to your reports of successes and problems found.

Just as a reminder:
IMPORTANT NOTE:  While AREDN encourages you to download, install and test the nightly builds and report any issues found,  DO NOT install them in any node that doesn’t have easy access (e.g., towers, water tanks or mountain tops).  By definition nightly builds are not to be considered production grade software.

AREDN Development Plan 2022


Following their recent code production release, AREDN has embarked on an ambitious development plan.  Here’s a basic overview of what is on their plate

Replace Perl code with Lua

The programming language for the user interface, services and many other functions is written in Perl.   The Perl libraries are very large and AREDN has embarked upon a project to replace it with Lua, a much lighter weight programming language designed to run in embedded devices.  

In steps, the team will update the “read-only” page to Lua: 

Main, Mesh Status, etc.

Then the read-write pages will be updated: 

  • Basic Setup     

  • Port Forwarding DHCP and Services     

  • Tunnel Server

  • Tunnel Client

  • Administration     

  • Advanced

  • Configuration

  • And some others

 

Resync with OpenWRT

Then the code base will be updated to OpenWRT 21.02.1.  Besides code enhancements and security fixes, it brings in:

AREDN® Release Notes v3.22.1.0 16 January 2022

 

The AREDN team is pleased to announce the general availability of the latest stable release of AREDN firmware.

 

This release includes many significant improvements in the underlying OpenWRT code and stability/scalability fixes to the OLSR mesh routing protocol.

 

List of Changes:

​

  1. The AREDN  simplified firmware filename standard has been changed to the default OpenWRT convention to leverage data files created at build time for future automation of firmware selection.

    When installing this firmware release, from prior firmware versions, you may get an error message similar to

    “This filename is NOT appropriate for this device.“
    “This device expects a file such as: aredn-3.22.1.0-main-ef2d605-ubnt-nano-m-xw-.*sysupgrade.bin”
    “Click OK to continue if you are CERTAIN that the file is correct”

    Ensure that you are loading the correct file by referring to the downloads page, then safely ignore the warning.   Once this release is loaded, this error message will never occur again.

 

  1. When the size of the hostname and service advertisements exceeded the size of a single network packet, only IP addresses would be known.  The...

Ham Radio Presentations at SCALE 17X on YouTube


The ham radio presentations from the SCALE 17X conference are now available on YouTube.

The presentations are:
1. Orv Beach, W6BI will detail that growth with emphasis on Southern California, with metrics, maps and graphs.  He'll also cover some of the more significant network events, including the ability to stream video of recent brush fires from networked mountaintop webcams to YouTube.

2. Paul Wilkinson, K6IG talks about “Raspberry Pi + HAM Radio = Inexpensive repeater system”. With little effort a very powerful HAM repeater can be made with a Raspberry Pi, two HAM radios, and an internet connection. Some additional, yet inexpensive, hardware is required.

3. Ben Kuo, AI6YR presents “Linux, Raspberry PI, RTLSDR, LAME, and Open Source: A Recipe For Responding To Natural Disasters”. He covers both the why's and how's of putting together your own Raspberry Pi-based, open source system to help your own local community tap into the power of the crowdsourcing and social media emergency management.
