Is there anything I could possibly use as a start to jam cell phones within a small radius. Such as the movie theaters or some crap. I was thinking something along the lines of the "Tv-B-Gone" and the things used by ambulances to make red lights green

It's illegal, so you'll have to build one yourself.

Then give up because you realized its far to difficult for you.
