This has to be a dumb question since I don't hear people talking about it at all. I see that we get like 3.5 miles of distance and I don't know whether that 400f or is it meters ceiling is a hard one or not BUT what about the wifi downlink??? If it's not LightBridge, what is it? Is it LB? Is it LB but they are not calling it that so they can sell it? What's the rub on why it doesn't say LightBridge in the features of the P4 when the P3 does. This feels like a dumb question but I can't find the answer. Can someone please help?
