I don’t know what your talking about there, they’re not lined with lead. My cell phone still got service whenever I went into a walk in at every restaurant I worked at when I was in college.
Bestaa is correct in that they greatly diminish the propagation of radio waves. They are not perfect faraday cages but a lot of the better insulated walk ins are very difficult to get radio waves into them. Cell service, walkie talkies, WiFi, GPS.
I’ve never walked into a walk in where my service wasn’t significantly impacted.
Walk-in coolers/freezers are giant Faraday cages. You can’t get wireless in or out, so it’d need to be wired.
