Amateur Radio Emergency Data Network™ is a high speed, self discovering, self configuring, fault tolerant, wireless computer network that can run for days from a fully charged car battery, or indefinitely with the addition of a modest solar array or other supplemental power source. The focus is on emergency communications. For more information on our Mesh Network check out the information we have below.

[ AREDN Supported Platform Matrix ]

Supported Platform Matrix
The supported platform matrix identifies the makes and models of hardware which may be used with AREDN firmware in the various frequency bands. The equipment marked with a green background is fully supported and tested. Models with the light green background are AREDN Stable, but, NOT recommended for new deployments. (Low memory non-MIMO device). Models with a red background are NOT supported nor are they compatible with AREDN firmware. The orange background indicates equipment that is likely to work well, but has not yet been thoroughly tested. Equipment with a yellow background is in the research stage and may or may not achieve fully-supported status depending on test results.

[ Mumble VOIP Chat Server and Client Software. ]

Mumble is an open source, low-latency, high quality voice chat software primarily intended for use while gaming. Tho it works extremely well over our Mesh Network. It will run under Windows, Mac, Linux and Raspberry Pi's. On Linux and Raspberry Pi's it can be found and installed Via the software package manager and the chat client and Server are separate packages.

[ What Is LQ, NLQ, EXT and how to easily understand it. ]

This information comes from Steve Lewis AB7PA and is a great example on LQ, NLQ, and TxMbps. Just as the LQ and NLQ numbers will be different, the same is true of the TxMbps number. These are "estimates" that are calculated independently by each node.

  • LQ or Link Quality is your node's view of the percent of OLSR (Optimized Link State Routing protocol) packets received from the neighbor node. These packets exchange mesh routing and advertised services information, and they include a sequence number that is used to identify missing packets which is a measure of the quality of the link.
  • NLQ or Neighbor Link Quality is the neighbor node's view of the percent of OLSR packets received from your node. This measures the quality of the link from the neighbor's side.
  • TxMbps or Transmit Megabits per Second is a calculated estimate of the data rate achieved across the link with the neighbor node. This column may show zero if the data being transmitted between these nodes is not sufficient for the metric to be calculated accurately.
