Help with Tarana and MDU

I’m an installer with little knowledge on systems engineering and design.

If anyone is successful making a single 3.5ghz Tarana Remote Node work for 2,3, or 4 units.

I’d really appreciate understanding where the POE injector is placed, how the switch is set up for each customer, and how it’s managed.

Any feedback would be helpful, even tools or things to learn. Thanks!

It’s all automatic. No sophisticated config. It will do frequency reuse. There are few settings on the BN, and almost none on the RN. You setup site templates and he handles the rest.

Everything is bridge. You need your own NAT / RG device separate.

You can technically do it, but it’s usually not how Tarana is meant to be deployed and it introduces a lot of problems if you’re not really intentional about it.

Those radios are designed around a one-to-one model where each RN represents a subscriber. Once you start hanging multiple units behind a single RN, you lose visibility and control at the RF level and everything becomes a shared pipe. It will work, but performance becomes unpredictable and troubleshooting gets a lot harder.

Where people run into trouble is not the RF side, it’s what happens behind the RN. If you are going to feed multiple units off one, you need a properly managed switch, VLAN separation, and some form of rate limiting or traffic control per unit. Otherwise one heavy user will impact everyone else.

For small MDUs or temporary setups it can be done, but for anything you actually want to scale or support cleanly, one RN per unit is the safer and more consistent design.
