Amateur Radio Emergency Data Network AREDN(tm) Firmware

http://www.arednmesh.org

About AREDN

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.

Ethernet Port usage

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:

• untagged: LAN devices - laptop, ipcam, voip phone, etc.
• vlan 1: WAN - gateway to connect AREDN network to home network and/or internet
• vlan 2: DtDLink (device to device) - AREDN network routing between nodes, typically cross band

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.

If the device's hardware supports POE (Power Over Ethernet) pass-through from main port to secondary port, an Advanced Setting option will show to turn on/off. This is useful to power ipCams or other mesh nodes by daisy chaining the network cable from one device to another. Then only one network cable may be needed to reach 2 or 3 devices on the tower. Be sure to check the power capacity in the vendor specifications to not exceed. The first device in the chain will provide the DHCP address to all LAN devices on all nodes (because it powers up first).

• TP-Link WBS210 v1
• TP-Link WBS210 v2
• TP-Link WBS510 v1
• TP-Link WBS510 v2

The Mikrotik hAP AC Lite, Ubiquiti AirRouter, and AirRouter HP are pre-configured with the following VLANs:

• Port 1: WAN Port - Packets in/out of this port are expected to be untagged. The node is (by default) configured to receive a DHCP assigned address from a home network, internet, or other foreign network.
• Port 5: DtDLink Port Mesh Routing -- Connect to another mesh node or 8021.q switch. Packets in/out of this port must be vlan 2 tagged, other packets are ignored.
• Ports 2-4: LAN devices -- Packets in/out of this port are expected to be untagged. The mesh node will (default) DHCP assign an IP address to your computer, ipCam, voip phone, etc. connected to these ports.

The GL.iNet GL-AR150 and GL-AR300M16 are pre-configured with the following VLANS:

• Port labeled "WAN": untagged = AREDN WAN
• Port labeled "LAN": untagged = AREDN LAN, vlan 2 = DtDLink (device to device)

The GL.iNet GL-AR750 is pre-configured with the following ports, left to right:

• Left Port with internet globe icon: WAN (untagged)
• Middle Port with "<..>" icon: DtDLink (vlan 2)
• Right Port with "<..>" icon: LAN (untagged)

IMPORTANT: For Gl.iNet devices, when initially installing AREDN on OpenWRT, you MUST uncheck the "Keep Settings" checkbox.

Submitting Bug Reports

Please submit all issues to http://github.com/aredn/aredn_ar71xx/issues

Developer Only Information

The AREDN firmware is based on OpenWrt with additional packages and patches. A Makefile automates the entire process to create firmware images.

Building with Docker

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>

Build Prerequisites

Please take a look at the OpenWrt documentation for a complete and up to date list of packages for your operating system.

On Ubuntu/Debian:

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

On openSUSE:

zypper install --type pattern devel_basis
zypper install git subversion ncurses-devel zlib-devel gawk unzip \
  perl-libxml-perl flex wget gettext-runtime quilt python \
  libopenssl-devel shellcheck lua51

On Arch:

pacman -S base-devel subversion zlib unzip perl-xml-libxml wget \
  quilt openssl shellcheck lua51 git

Building firmware images

To obtain the source and build the firmware locally use:

bash
git clone https://github.com/aredn/aredn_ar71xx.git
cd aredn_ar71xx
vi config.mk # enter your callsign, etc.
# build default legacy ar71xx target ubnt and tplink images
make  
# build and add legacy ar71xx target mikrotik images
make SUBTARGET=mikrotik
# build and add ath79 target (latest linux kernel) ubnt, tplink, and gl images
make MAINTARGET=ath79

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.

How to build prior builds of AREDN

Prior AREDN images can be rebuilt. Replace one of the following after the "cd aredn_ar71xx" command above:

AREDN release 3.20.3.1

git checkout 3.20.3.1

AREDN release 3.20.3.0

git checkout 3.20.3.0

AREDN release 3.19.3.0

git checkout 3.19.3.0

AREDN release 3.18.9.0

git checkout 3.18.9.0

AREDN release 3.16.2.0

git checkout 3.16.2.0

AREDN release 3.16.1.1

git checkout 3.16.1.1-make

git checkout 91ee867

Return to most current changes

git checkout develop

Directory Layout

Included in the git Repo:
config.mk    <- build settings
openwrt.mk   <- which openwrt repo and branch/tag/commit to use
feeds.conf/  <- custom package feeds (edit to point to your clone of aredn_packages)
files/       <- file system in AERDN created images, most customizations go here
patches/     <- patches to openwrt go here 
scripts/     <- tests and other scripts called from the build 
configs/     <- definitions of features in the devices' kernel and what packages to include
Makefile     <- the build definition
README.md    <- this file

Created by the build:
openwrt/     <- cloned openwrt repository
firmware/    <- the build will place the images here
results/     <- code checks and other test results in jUnit xml format

Patches with quilt

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 the quilt tool. Please configure quilt as described in OpenWrt Quilt.

Add, modify or delete a patch

Switch to the openwrt directory:

cd openwrt

Now you can use the quilt commands.

Example: add a patch

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
