I don't see why you wanted to. Unless you have a vendetta with them. I'm not sure how portable they are but I'd imagine they'd work. But on the other hand they probably have unjammers and service enhnacer i'm guessing just beacuse you always have 6 bars in there.
So would that plan be to sit in the car right outside the place? I'm thinking if there jammers, there has to be unjammers but let us know how this goes.
I remember a story awhile back about some high school principal using a jammer so kids couldn't talk on their phones at school. So I'm guessing they actually work.
Yes they work, but for a wider area and to block out a large amount of users completely requires one that can output wireless signals that interfere with carrier signals and therefore needs more power. Usually they start pocket sized for a small area and work there way up in size for larger areas.
Yes they do work. I'm not sure about that one though. The head of the math department in my high school made one. That guy was such a fucking douche and a nerd. it blocked about half of the school. Its a pretty good sized school also. I heard they are illegal though?
For what it's worth, jamming is probably illegal mostly from being an FCC violation. Because to jam the frequency you have to broadcast the jamming signal all over the place which is not FCC approved, I'm guessing this is the case. Not that anyone should care, this is Bad Ideas.
They work by over-powering the signals in a given range. If you have ever used a CB radio, some times assholes with more power than you will "squash" you. Same principal, only digital so harder to squash, plus you'd need more power than the tower in the are, which are everywhere.

And you're right, they most likely have some sort of system to avoid jamming. I'll try it out though.
Welcome to Bad Ideas. :cool:
Well, I got it today.
That's about an 18-day delay from the standard 'weekly' shipping.
It's pretty light, and I'll be testing it tonight at a public place, I'm waiting for the streets to crowd up.
As far as their function, yes: http://en.wikipedia.org/wiki/Mobile_phone_jammer
That is all.
