Well, I don't think you walk around with your FRN setup, so in that case it is a fixed infrastructure.
Sorry, but I have to disagree again. Infrastructure is a network of linked or intertwined devices. In case of FRN this may
apply. However nowhere in the document it's explained what exactly "fixed infrastructure" is.
Once each node has its own net, then it's not infrastructure as the devices are not paired and thus don't belong to any network. It's the user who dials DTMF on specific node to connect them.
It's the same logic as calling PMR446 handheld "base station" if it's used from one apartment to another and not outside.
I also think that it's not relevant that the FRN is not constantly in use.
As long as practical deployment is in question then baby monitors would prove to show much higher interference factor than any FRN (or Echolink) node.
I think that PMR446 is not planned by the authorities to use for technical experiments.
It's not forbidden though..
Looking at other options:
- CB license specifically excludes VOIP
- LPD433 is not allowed in my country
- FRS not allowed too
- KDR444 is not yet allowed outside Norway/Sweden
- other national license exempt exclude VOIP usage
- aaaand PMR446 even if allowed would be quite limited in terms of linking due to "fixed infrastructure" term, which is nowhere explained
So, I'm out of options...
