AREDN wireless networks are deployed by licensed Amateur Radio operators, Technician Class or higher, under FCC Part 97 allocations adjacent to FCC part 15, unlicensed, WIFI, allocations. They are configured as ad-hoc nodes to form mesh networks. The firmware created below enables the effective use of valuable and dedicated frequencies for communication services to government and private relief organizations in times of disaster or other emergencies.
Amateur Radio frequencies are relatively clean of noise from the commercial allocations and ensure usability for Amateur Radio Operators. This firmware enables 802.11n wireless networks to be created and expanded with minimal to no pre-planning or IT expertise. A user can deploy a ‘node’ anywhere to connect in and extend an AREDN network. Device hardware options exist to provide sector coverage, build point-to-point links, and connect end point services to the network. High speed link rates are routinely achieved over long distances, e.g. 60Mbps+ on 10MHz channels over 80km links.

This is the active ‘develop’ branch with latest AREDN code. At anytime a new change may be broken or break prior capabilities.
The Amateur Radio community is encouraged to participate in loading the images produced from a “nightly build” and run the AREDN firmware in a variety of environments. Given new features may not yet be documented, participants should already have a basic knowledge of Linux and Networking to understand and provide useful feedback to the Developer submitting the code.
The goal of participation is to obtain confidence that new features and the overall mesh node is stable. The more participation, the earlier an issue is found, the faster an enhancement will be turned into a release.
Here is a summary of significant features added since 126.96.36.199 was released:

The standard Ethernet port of an AREDN device uses the following vlan tags. An 802.1Q switch is necessary to utilize the vlan tagged networks:
The following devices have a peculiar port configuration due to a limitation in the Ethernet driver. The ‘Main" port is used for LAN devices only. The “Secondary” port is WAN and DtDLink usage only. Depending on deployed usage, 2 cat5 cables may be needed.
The following devices have enhanced Ethernet port usage. A single cat5 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 ipCams or other mesh nodes.
The following devices have standard Main ports and non-functional Secondary Ports
Please submit all issues to http://github.com/aredn/aredn_ar71xx/issues
The AREDN firmware is based on OpenWrt with additional packages and patches. A Makefile automates the entire process to create firmware images.
Installing the Docker environment on your windows/linux/mac machine is a pre-requisite. A docker ‘container’ has been pre-configured with an aredn linux build environment. Alternative instructions are below if you wish to setup your linux install with the compiler pre-requisites necessary to do the build.
To build with docker:
docker pull arednmesh/builder
docker run -it --name builder arednmesh/builder
To pull an image (or any other file) out of the docker container:
docker cp builder:/opt/aredn/aredn_ar71xx/firmware/targets/ar71xx/generic/<image>.bin <local directory>
Please take a look at the OpenWrt documentation for a complete and up to date list of packages for your operating system.
apt-get install git subversion build-essential libncurses5-dev \
zlib1g-dev gawk unzip libxml-perl flex wget gettext quilt \
python libssl-dev shellcheck lua5.1

zypper install git subversion ncurses-devel zlib-devel gawk unzip \

To obtain the source and build the firmware locally use:
git clone https://github.com/aredn/aredn_ar71xx.git cd aredn_ar71xx vi config.mk # enter your callsign, etc. # build default ubnt and tplink images make # build and add mikrotik images to firmware dir make SUBTARGET=mikrotik
Building the images may take minutes or hours depending on the machine.
For more details see build options.
Review the build options in config.mk:
-j <number of cores + 1>.
V=s will give more verbose error messages.
An internet connection is required during the build process. A good internet connection can improve the build time.
You need approximately 10GB of space for the build.
Prior AREDN images can be rebuilt. Replace one of the following after the “cd aredn_ar71xx” command above:
AREDN release 188.8.131.52
git checkout 184.108.40.206
AREDN release 220.127.116.11
git checkout 18.104.22.168

The patches directory contains quilt patches applied on top of the openwrt git repo defined in config.mk.
If a patch is not yet included upstream, it can be placed in the
patches directory with
quilt tool. Please configure
quilt as described in
Switch to the openwrt directory:
Now you can use the
quilt push -a # apply all patches quilt new 008-awesome.patch # tell quilt to create a new patch quilt edit somedir/somefile1 # edit files quilt edit somedir/somefile2 quilt refresh # creates/updates the patch file
