Luckily people are researching higher frequency, targeted communication means. These systems should be able to target the reciever in order to lessen interference and because of the higher frequency the signals decay faster, also lessening RF pollution.We're already dealing with the bullshit of "The Internet of Things." I had a network TV shoot fucked because somebody's goddamn watch was busy screaming on the exact same frequency as someone's mic - a frequency that had been cleared, vetted and protected by the network sound shop. But the "Internet of Things" doesn't give a shit, because the only thing the watch wants to do is find out what time it is every 10 seconds (because why bother putting a decent crystal regulator on it when you're on the Internet?), thereby giving me a lovely raspberry while I'm trying to record a talk show.
