It’s well past time to legalize phone signal jammers. Think how nice it would be if schools, churches, restaurants and businesses could scramble phone signals within their boundaries.
They don’t need to jam them which will interfere with other radio services like police and fire. They would just make the restaurant a faraday cage and no signals would get out. I went to an hospital ER that had a faraday cage so you couldn’t use radio electronics. I had to go outside to get a signal. It stops patients from looking up on the web or calling k00ky med quacks for advice.
"We're jammin' in the name of the Lord!"
