Following on the heels of the inclusion of the Babel routing protocol to the AREDN software is another significant enhancement: nightly build 20250219 adds PtP (Point to Point) and PtMP (Point to MultiPoint) configurations. These protocols can be found in the Radio section of the AREDN UI:
Here's a brief explanation of each of them:
Mesh PtMP: This makes a node act like your common access point, where Mesh Station nodes can connect to it, but not to each other, and the Mesh PtMP can only connect to Station nodes.
Mesh PtP: Same as above except only a single Station is permitted to connect, specified by a MAC address.
Mesh Station: Can connect to a Mesh PtMP or, if it’s the authorized node, a Mesh PtP. It cannot connect to anything else.
The new modes also require a new SSID. This changed SSID is a necessary by-product of how these modes are implemented. Our current Mesh uses the WiFi Ad-Hoc radio...

The AREDN team is introducing a new networking technology into the nightly builds with the ultimate long term goal of replacing OLSR.
OLSR has many faults which AREDN has lived with for a long time. For the last couple of years we’ve been looking at alternatives and making incremental steps in the codebase to allow us to introduce something new. We can finally do that by adding Babel (https://www.irif.fr/~jch/software/babel/) to AREDN.
Babel has a number of qualities which make it good for AREDN. First, it’s a loop free protocol so, regardless of how the network is changing, routing loops will never form in the network. Second, it’s primarily a reactive protocol which sends changes to neighbors when needed rather than broadcasting its state continually. Third, the protocol understands the difference between wired, wireless, and tunneled links – the three link types AREDN utilizes. Fourth, it’s a layer-3 routing protocol, which integrates easily with how AREDN already operates. Fifth, it’s highly configurable which will allow an optimal setup for our use case. Finally, it’s simple.
We considered a number of options, and another contender was B.A.T.M.A.N. Advanced. Unfortunately this protocol is not a good fit for AREDN as it primarily focuses on level-2 wireless networking. AREDN needs a protocol which can do more. We...
