Here you will find information about Cell Phone Jammers. A cell phone jammer - also named cellphone jammer - works simply put, like this: within a certain area the jammer emits a signal, at high enough power and in the same frequency range as cellular phones in that area; the signal of both cell phone jammer and cellular phones then meet/clash whereby neutralizing/dropping each others signal, so the cell phone signal isn't able to contact the cellular network.
Image you're in a restaurant and you got one of those cell phone jammers. With your cellphone jammer switched on you will be able to silence those persons who insist on using their cell phone in the most indiscrete way, The cool thing is that they have no idea whatsoever that it is you that has shut them off.
Their signal has dropped on their phone but they haven't a clue what's happening. They may think it's because of the building they're in or there's something wrong with their cell phone.
When you have finished your meal or drinks in peace and quiet, you can then switch off your cell phone jammer and the cell phones in the area will operate as normal again.
This is what could be done with cell phone jammers. But do we want just everybody to do that?
I don't think so, but maybe you can imagine that there are exceptions to make in some cases.
By law it's prohibited to use a jammer.
Here's what is stated by the Federal Communications Commission (FCC) about blocking and jamming communications:
" The operation of transmitters designed to jam or block wireless communications is a violation of the Communications Act of 1934, as amended ("Act"). See 47 U.S.C. Sections 301, 302a, 333. The Act prohibits any person from willfully or maliciously interfering with the radio communications of any station licensed or authorized under the Act or operated by the U.S. government. 47 U.S.C. Section 333. The manufacture, importation, sale or offer for sale, including advertising, of devices designed to block or jam wireless transmissions is prohibited. 47 U.S.C. Section 302a(b). Parties in violation of these provisions may be subject to the penalties set out in 47 U.S.C. Sections 501-510. Fines for a first offense can range as high as $11,000 for each violation or imprisonment for up to one year, and the device used may also be seized and forfeited to the U.S. government."
Arguments are that using a cell phone jammer you're violating the rights/properties of licensed transmission networks.
