I'm new to and trying to get up to speeds with LORA & IoT protocols. I'm trying to understand how LORA would be deployed & configured as a service provider, where I might want to deploy some KNOT LR9's (US based), but I want to ensure only devices I've authorized are able to connect. It seems that there is no way to control which clients connect from the documentation I've been able to locate.

Specifically I'd like to have a way to authorize a client much like with wifi setting default-authenticate=no and then adding each MAC address under wireless/registration-table, and reject any client device that isn't on my approved list. If this is currently possible, can someone show or point to an example config of how it is accomplished in ROS?

Also, if possible, is there any way the client access authorization be controlled via RADIUS?

I am no Lora-Specialist...
I only have limited experience with a Mikrotik R11e-LoRa8 Gateway and some Sensors & IO-Devices.

On Mikrotik, you can define on the LoRaWAN-Gateway which Lora-Networks / Lora-Servers are allowed.
See Wiki -> https://wiki.mikrotik.com/wiki/Manual:Interface/Lora

Authentication and Authorization are done by the Lora-Servers not the Gateway
