The industrial wireless microphones and headsets used in TV production are exceptional for sound quality and delay.
They require a special license to use, and require dedicated hardware (ie. they won't connect to a phone). Shows whats possible if walled garden and regulatory constraints are lifted though.
I'm not sure what they're talking about... Pro audio gear doesn't need a special license unless it's old spectrum that was purchased largely to roll out low band 5G a few years ago. 99% of the industry has moved on though.
Also, a lot of movie stuff, especially at budgets below AAA box office extravaganzas, still use wired gear. Zero latency, no potential audio loss, and dirt cheap.
