The new thing here is the scale of deployment since utilities are replacing old human readable meters en masse.
What new thing? Radio waves have been bombarding humans for decades.
Just so you know - I neither own nor operate a cell phone or satellite TV. My microwave oven died and I’m not sure I’ll replace it. So I’m not a huge fan of modern wireless tech, but mainly because I believe I can do without.
I've got an Itron on the back of my house now. But instead of using an RF signal for remote meter reading, mine's tied into the fiber network that I use for my internet (and will use for TV once my dish contract ends).
No fancy billing schemes or rates yet, but that's coming.
