While it IS true that here in the US, the FCC has banned the use of active cell phone jamming technology, only an FCC agent with special equipment would even be able to tell it was being used! If you're a member of the general public and you're being jammed, you'd only think you were in a dead zone, because you'd simply see zero bars.
However, it is now possible for businesses to engage in PASSIVE jamming that IS legal, at least theoretically. It's called Cell Phone Blocking Wallpaper, and it uses the same metal mesh principle used in microwave ovens to keep the microwave radiation from leaking out through the window. And the only way the FCC could verify that it's being used is to rip the wallpaper off of the wall!
