Technically, which phone of the 50 people present would that be? A jamming system jams, a whole frequency band etc. But it is not capable of jamming special information transported within this jammed frequencies. This could only be done if the "jamming system" is kind of a firewall instead, and thus it has to create a own cell where all the communication is send through, which means "tons" of radiation for those people in the "blocked" room.

Yeah. I'd like to go to the cinema and have some stupid watchdog people read all my messages and whatnot on the phone during that time.

Why all this technical stuff, when people just have to "silence" their phone using one of the various options available? That or blocking the whole signal for one room (e.g. cinema).
