ARRL Call to Action in Defense of Part 97 Allocations in the 3 and 5 GHz Bands

The FCC WT Docket 19-348 and WT Docket 19-138 will severely curtail growth of one of the newest and most effective means for Amateurs to support emergency communications.  Existing installations will be severely curtailed or, with no reasonable alternatives, be forced to cease operations.  Thousands of hams have built or are in the process of constructing high-speed data networks in the 3 & 5 GHz ham microwave allocations.

Background

AREDN (Amateur Radio Emergency Data Network) was an outgrowth of the ARRL working group on High-Speed Multimedia (HSMM).  It has evolved over the past 10-12 years from its first implementation by Broadband Hamnet (BBHN).  Over the years the AREDN Project has developed software support for nearly 70 commercial wireless routers---moving them from their Part 15 allocation into adjacent Part...

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...

​ARRL Awards 2018 Microwave Development Award to AREDN Team

​The ARRL announced that The Amateur Radio Emergency Data Network (AREDN) project team was named as recipient of the 2018 ARRL Microwave Development Award for its initiatives to utilize Amateur Radio’s microwave bands. These included extending the network’s high-speed multimedia capabilities from solely 2.4 GHz to 900 MHz, 3 GHz, and 5.8 GHz, and adding 802.11n protocol to improve data throughput. The Board also acknowledged the efforts of the many AREDN implementation groups around the country who are building networks based on this technology and who stand ready to utilize them to serve the needs of their communities in times of disaster. 

​AREDN Project Announces Strategic Changes

AREDN forms a non-profit corporation to ensure continuity

The project saw the need for more formal governance and as a result, took the strategic step of organizing as a non-profit corporation.  This will help protect the user-community investments in mesh networking by setting up the framework for long-term resource management, research, and development. 

Our mission is still focused on providing the Amateur Radio Community with software, education, and support to enable them to aid public safety, emergency response and disaster relief agencies with high-speed multimedia data networks.

Continuing to rely on the financial support of a few individuals is not a sustainable means of supporting the project. Without more widespread support, the community’s growing investment in network equipment and...

AREDN code repositories on GitHub

The AREDN source code repositories are now accessible on GitHub at https://GitHub.com/aredn/aredn_ar71xx .   GitHub is one of the largest open source hosting services with over 40 million users.   Anyone with basic knowledge of Linux and git can now compile AREDN images and contribute changes.   If you have a background in application or firmware development, the hurdle to get started and contribute to the ham community is now much lower.

GitHub also includes an issue tracking feature to capture feature requests, bug reports, and other issues.  This immediately replaces our former defect tracking tool (Bloodhound).

The GitHub setup is intended to jump AREDN forward to stay current, and benefiting from, the 1000+ developers of Linux and...

​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...

​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.

​AREDN Group in South Africa Responds to Fire Disaster

A group of amateur radio operators in South Africa known as the the Mossel Bay Mesh Network responded to a call for emergency communications assistance in the recent fire disaster in the Western Cape area. 

After the fires began on 7 June, a call went out for amateur radio assistance on 8 June when cell phone, landline and Internet services were lost.Hams responding to the call include: ZS2I, ZS1Q, ZS1ZS, ZS1HB, ZR1AOC and ZS1I. These radio amateurs worked around the clock to assist their local communities. Johan Terblanche, ZS1I, an administrator of the AREDN Mossel Bay Mesh Network reports that disaster communication links remained active until normal telecommunication service was restored on June 11, while the local hams remain on high alert.

It has been reported that the widespread fire caused a number of fatalities, destroyed over...

New Paper on AREDN Published by TAPR

The Proceedings of the 2015 Digital Communications Conference include a paper, The AREDN Project by Andre Hansen, K6AH, which introduces AREDN, describes implementation techniques and concludes with a roadmap for the future.

Abstract

Mesh technology has been around for ten years or more. Over the past two years a team of developers has advanced the art by porting Broadband‐Hamnet’s extremely popular mesh firmware to the Ubiquiti airMAX line of commercial Wireless ISP routers and expanded its utility across a wide range of microwave bands. This has literally changed the complexion of mesh technology from an experimental, hobby‐oriented, novelty into a viable alternative network suitable for restoring some degree of Inter/intra‐net connectivity “when all else fails.”

AREDN™ - The Amateur Radio Emergency Data Network

Mesh technology has evolved over the years.  Most notably, Broadband-Hamnet™ (BBHN) has made substantial progress over the past 2 years in expanding their unique approach to environmentally robust, commercially available, Ubiquiti, hardware.  This has changed the complexion of mesh implementations from an experimental, hobby-oriented, novelty into a viable alternative network suitable for restoring some level of Inter/intra-net connectivity when “all else fails.”

Recently, the developers of BBHN software have kicked-off a new project focused on taking this technology to the next level.  Comprised of the project manager, developers, and several of the testers who brought BBHN to Ubiquiti hardware, this team is geared to pick up where BBHN left-off.

The AREDN Project mission is to provide the Amateur Radio Community with a quality solution for...
