Hello Aredn members,
Looking at doing some retooling of our current Aredn setup. We current are looking at only allowing the users to come through the 2.4Ghz access points and then using 5Ghz or unlicensed frequency from Unifi to run the data around the backbone.
Here are my questions.
1. Is there a way to pin the AP points so it will only respond to users on 2.4Ghz and any other requests for an IP on other frequencies will be ignored. This would be similar to the way you would do it on the full size internet.
2. If you decide to run unlicensed backbone systems is there a way to interface the Aredn nodes with it via a network switch or is the a recommended way to make it work?
3. How would you setup a bridge in the Aredn network to get it to repeat the signal and pass it along if the distance between two sites is to great or you have terrain issues that is blocking a direct link.
Thanks!

I don't know about where you are, but here in the large metro area, the performance on 2 GHz is so bad because there is just so much RF on 2 GHz.
Our system is out in the rural part of the state. I'm open to suggestions, what does everyone else use for AP user points as far as frequenices are concerned?
Thanks!

The majority access the local network on 5 GHz.
We have one user on 2.4 and one user on 900 MHz.

What are people using for backbone links? Are they using something other than 5 GHz?
A lot of 3 GHz links around here.
Who is making a good set of equipment for 3 GHz? I'm willing to experiment if it works well then go with using it.
I don't know if anyone is making 3 GHz equipment these days. Ubiquiti had several models including Rockets which work fine for links. However, I don't think any of those are being made any more and the ones available are quite expensive. I bought four Rocket M3s a few years ago, and am happy that I got them.
I wouldn't expect new equipment to be designed for this band for ham use, or to be readily converted to ham use. While we are allowed to continue operations in the 3.3-3.45GHz band, it is uncertain for how much longer. That has already been removed from Part 97, and is just being allowed by a memo until the usage of that band is finalized by the FCC. http://www.arrl.org/3-ghz-band
thank you for the update on that. Any other bands being used for backbone that is working well?
We currently use 5 GHz channels for both user access and backbone links. The same band can be used for both, but recommend at least one channel separation between them.
We've considered 60 GHz for short hops, and are looking at 10 GHz for a multi-county backbone for all amateur radio use (not just AREDN).
Is there 10 Ghz equipment being made at this time?
The only gear we're aware of is made by Mimosa. It's quite expensive, but can be persuaded to move down into the amateur radio band. (10.0-10.5 GHz). We hope to use it as a generic ham radio IP backbone, welcome to all comers (AREDN, DMR, Allstar, whatever). Test link will hopefully be operational by the end of the month, weather permitting.
I'm assuming you are talking about there PTP system as shown in the link below. Does the software from AREDN support this product or your eluding to it being tested as a new release?

We bought the B11s, plus various antennas. It won't be an AREDN device. It'll run their native software and support AREDN networking via VLAN2.
Hi, Stephen:
I see no valid reason to segregate users to a single band...especially 2.4 GHz wherein
there is only one clear ham channel...and that channel has 1/2 bandiwdth capability.
I do see a case for segregating user access to non-backhaul channels.
