AREDN Receives Grant from Yasme Foundation

The AREDN Project was recently honored by the Yasme Foundation with the award of a $7000 grant for the purchase of a 20 GHz spectrum analyzer.  The analyzer will be used to understand the characteristics of 802.11 protocols in the unique, long-distance mesh, configurations of AREDN implementations.  It will also afford us the ability to measure, and perhaps, improve the quality of transmissions emanating from AREDN-supported devices.

The AREDN Project team is grateful to the Yasme Foundation for taking the time to consider its need for a spectrum analyzer.  Andre Hansen, K6AH, in speaking for the entire team said, “To be awarded this grant is particularly gratifying for us because it acknowledges the value the AREDN Project affords Amateur Radio.”

The Yasme Foundation is a 501(c)(3) not-for-profit corporation organized to support scientific and educational projects related to amateur radio. Their support includes long distance communication (DXing), the introduction and promotion of amateur radio in developing nations and encouraging youth participation in amateur radio.

AREDN® Ambassadors

The AREDN® team is pleased to announce the start of a new program to recognize people who are actively contributing to spreading the word about how hams can use our 21st century mesh networking technology to provide high-speed data communications when disasters strike.

We call these special people “AREDN® Ambassadors”.

These are key members of our community who:

  • Perform a significant amount of testing to help us verify new features and bug fixes and uncover new flaws.
  • Improve feature sets
  • Identify new equipment which extends our supported platforms
  • Donate their time and effort to building and operating mesh networks
  • Promote the AREDN® Project through presentations to clubs and hamfests
  • Engage local government, hospitals and other served agencies in discussions about how hams can provide 21st century solutions to emergency communications needs
  • Constantly improve their networking skills
  • Commit to support and advise local hams about methods to build successful networks
  • Develop new applications and uses for an AREDN® mesh network

We are proud to announce our first group of AREDN® Ambassadors. They are:

Orv Beach, W6BI
Mark Herson, N2MH
Karen Herson, KD2KHJ

Congratulations to each of you!

Improved Capability on XW Device Ports

 

Full functionality of both ports on Nanostation M2 and M5 XW units is now available.

Joe AE6XE found a way to remove the limitations noted in the forum thread.   Both Ethernet ports on the Nanostation M2/M5 devices are now configured and working without limitations.  This code will be available after tonight's build on Nov 22, 2018.  Text included in the AREDN GitHub README:

The following devices have enhanced Ethernet port usage.

  • NanoStation M5 XW
  • NanoStation M2 XW

A single CAT5 cable to the device could be plugged into ether the 'main' or 'secondary' port with standard port functionality. Both ports can be used interchangeably and simultaneously with LAN devices on both ports at the same time. POE PassThough can be turned on in Advanced Settings to power IP cameras or other mesh nodes. It is passive' POE, which means whatever voltage you supply the M5 XW with, that voltage is passed though to the secondary port and device.  It could be between...

California Hams Provide Fire Videos


Local amateur radio operators are responding to the recent and ongoing fires in California in many ways. Several of these hams have built a high-speed multimedia AREDN mesh network which was used to deliver live streaming video of the fires in progress.

In Ventura County, Orv Breach W6BI, Paul Straus WD6EBY and Ben Kuo AI6YR installed high-definition cameras in their portion of the growing Southern California AREDN network. They were able to figure out how to send to live video stream across the mesh network to then Internet and finally to YouTube for public access.

Ben AI6YR reports that their mesh network stayed operational even when the Spectrum cable, Internet access and phone system went down across the region. People were able to use the mesh network to keep updated on emergency information.

Ham Radio 2.0 Interviews AREDN Developers

Jason KC5HWB continues to produce a great series of ham radio videos on YouTube. In Episode 159, Jason interviews Joe AE6XE and Darryl K5DLQ from the AREDN development team. They describe the many improvements in the latest AREDN release version 3.18.9.0 and talk about the development process. They discuss the expanded list of supported devices which now includes the newer Ubiquiti AIrMax models and several units from Mikrotik.Joe and Darryl tell the viewers about our plans to provide a Raspberry Pi firmware installer which is being developed by K6RUN. 

Subscribe to Jason's YouTube channel and visit his website HamRadio2.0 Live from the Hamshack.


Installation Instructions for Mikrotik Devices


Download the Mikrotik .bin and the .elf file from downloads.arednmesh.org location:

  •  elf  :  this is the image to boot the mikrotik device with.  It only uses RAM on the device (which is lost with a power cycle and still boots with Mikrotik OS)
  • .bin :  once the device is booted with the .elf image and running,  copy this up to /tmp and type a command that will update the flash with AREDN, so it then boots AREDN on a power cycle.
 
The procedure is very different and it is the opposite of a Ubiquiti installation.  Opposite in that with Ubiquiti, the device is a tftp server and the tftp client is run on the laptop to send up the image.  With Mikrotik, the device is a tftp client and the laptop has to be configured to run a tftp server (also dhcp and bootp server)  on a linux or windows machine.    This is all done by a program called dnsmasq (it has all 3 servers).  
 

Linux procedure:

 
  1. Create a directory on your laptop /...
