It's done in other countries in public buildings, that's been reported over and over again.

It's illegal in the United States to do so. If it was in fact happening, then the FCC would be all over the establishment, because every cell provider would be complaining.

Nobody is going to go through the trouble to block each and every cell phone band. On my phone they would have to block two GSM bands, the digital CDMA bands, and the analog bands to keep me from making or getting a call.

Maybe Mr Elliott needs to get a better phone or a better service provider? And some medication for the paranoia? A speaker can press a button that can reach his room probably through a half dozen floors, but not out a window in the parking lot? Give me a break.

Jammers in this country are very agressively hunted down if they are on ham bands, pager bands, business bands, and cell phone bands. When it happens, you hope it's the FCC who gets to them first, because if it's the people doing the hunting, there won't be much of their equipment left.
