@Michael Arg, hm. I thought th whole time about how the previous line "depends on arch[i]tecture, the weather, the phase of the moon...." was referring to the FAA airport clearance safety standards for 5G. I mean not penetrating aircraft radar, has very similar language. I swear I know the frequencies for Wifi might sound the same but are not equivalent, but I swear someone else would read what I read too. =) Too much tangent for a tech chat, or not enough tangent to scatter the radio signal? :)
