What I've always found interesting is that the 5G being referred to, in fact means "Fifth Generation", and was orignally coined
by AT&T as a label for the NEW 5th Generation Operating System for cellphones. The wireless standard for routers is 2.4 gigabit,
and 5 gigabit. Different creatures entirely. 5G Cell Phone systems may in fact use frequencies at 5 Gigabit and higher (I understand
that some of the shorter distance point to point towers can go up to 30+ Gigabit or even higher, but this is relay, not end delivery.
You home router uses both 4.2. and 5 gigabit deliveries, running at less then 1 watt output.
