OK, apologies if I'm misunderstanding here, but the hakshop says:
NANO Tactical Elite: NANO Tactical, plus RaLink RT5370 (Tertiary WiFi Radio) & 90 degree in-case 500 mW antenna upgrade.
So is that not a third physical radio?
I get that you can split one physical interface/radio into multiple logical units/vlans, but that is done in software, so could be (and I assume is) done on the nano basic model.
So what advantage does the addition of the Ralink bring?
