Inductive loops, 1950s technology.

That's the tech you see when "agents" are talking into their sleeve? Old school.

No, induction requires multiple turns of wire to be run around the area the receiver will be in, and powerful amplifiers. Very limited range and requires installation in advance, like hidden under the floor or in the ceiling. The only use I’ve seen for it is in language labs in schools built back then. The vacuum tube amps used would bring a fortune on eBay today.
