    Has anyone had an experience being jammed, and known about it? I don't mean indoors, in a theator, or church, but in some public place where you normally get coverage. I've heard mixed reports on this. I've heard that the small handheld jammers that you can by online are not effective, unless indoors at very close range. But they're starting to come out with pretty powerful ones, and sometimes I just lose my signal in an area where I'm positive there's coverage. What gives here? Anyone?

    Jammers are illegal in the US. The FCC prohibits interference with controlled frequencies.

    Of course they are!! But do you think that stops people from using them? Just do a web search and see what's available...!!

    As Jay2The Rescue says, they are illegal, but some church's and other places advertise that they jam your signals.

    Hospitals are trying to get it incorporated, because some phones interfere with some of the life-saving equipment they use - or so they say.

    Yes, phones do interfere with heart monitors, but so will the jammers, and the phones will add more to the problem when they kick into high power to try and find the network.

    the hospitals must really be serious about the phone in hospital thing. when my brother was in the hospital from heart problems, at the main entrance there was a BIG sign that strictly forbid cell phones being 'on' passed the sign and security actually walked around and if they saw you with a cell phone asked you to turn it off and leave it off until you leave the hospital.

    In my experience there are only 2 departments that allow cell phone use, and they are usually on the top floor away from any other critical patients. The maternity ward, and some hospitals also have a ward for terminal patients that cell phones are allowed in.

    The waiting rooms in this hospital allowed cell phones to be used, but once you leave the waiting room they were supposed to be turned off.

    I worked for a Major healthcare company and they came out with a policy stating cell phones didnt have any effect until you were about 5 feet within the equipment.

    On the older phones, I guess I can see the problem, but are the newer phones better or worse for the equipment?

    In my hospital Cingular has installed microcells, with many physicians and support staff using them. I believe that unless you are very close to the equipment, it is not a problem, especially when the phone power will be low since signal will be pretty good inside.

    Perfect example of real policy at work. When freq. and channel power is controlled and known it is fine. It is the unmanaged use of RF (cel phone or otherwise) that can cause issues in a hospital...and on a plane.

    I have used jammers (for testing purposes). You can have a device the size of a small PDA that can provide enough juice in random freq. hopping fashion to jam an entire movie theater.

    As stated, it is illegal to interfere with spectrum in the US.

    Thanks. I think I will stay with my ideals. :)

    Be respectful in regards of where you are when you are using your phone.

    Just plain common courtesy, I guess is what I am trying to say.

    A micro cell is a small short-range "cell site". If there are many installed in a building then the phone's output will be low because it will have no problems communicating with the "towers" it sees. These can be small little antennas installed in the ceiling. Most often they are disguised to look like smoke detectors.
