We're Jammin', Hope You Like Jammin' Too

theodp writes "Slate ponders whether a climate where anything can be photographed or surreptitiously recorded means the once-esoteric world of cell-phone jamming will become mainstream. Sites now offer portable cell-phone jammers that can provide you with the same kind of security bubbles used to thwart industrial spies, hostage-takers and bomb detonators. While actively jamming a cell-phone signal is illegal in the US, a distributor reports most of his sales go to US customers, including universities which use the technology to stop students from diddling away on phones during lectures."

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.

Well that's not exactly a great idea, now you would be transmitting a signal, just like a cell phone, as well. And the other persons phone will still try to keep in contact with the tower, so it will transmit periodically, so now you have two devices transmitting RF radiation near the medical equipment. Jamming is like screaming in someone's ear in order to keep them from hearing someone else talk.
