Anti-cell phone paint could block your signal

Cell phone blocking paintHave you ever been disturbed in a movie theater by the aggressive ringtone of a cell phone? Your problem could be solved soon. NaturalNano is currently developing a cell phone blocking paint that could prevent all cell phone signal from going in and out of a building.

Halloysite nanotubes coated with copper blended with the paint can prevent specific radio frequency ranges from entering or leaving a room. The paint can be applied to the exterior of a building to prevent any cell phone signal from entering it. To enable transmissions in specific rooms, a small antenna which will relay the signal outside can be installed in the room.

This anti-cell phone paint, however, raises some public safety concerns. Because it would hinder communications greatly in the case of an emergency, cell phone blocking has been made illegal in many states by public safety officials.

I could see the cell phone blocking paint used first in detention centers, where many prisoners can get a hand on cell phones and continue their activities while being detained. However, I don’t think we’ll see anti-cell phone rooms in public buildings anytime soon because of the safety concerns it would raise.

    Cell phone signals can be blocked and there is no law on the books to stop it. Your statement on safety is bunk…we did not use cell phones and they were safe then. Currently any business wanting to block or shield themselves using paint or other material can and should if they feel the need.

    As Billy said, we managed to survive these long years without cell phones. Sure, they are a major source of communication but people wont die in large numbers if the signal was blocked in certain areas.

    Signs can be marked to show that cell signals are being blocked and people can act accordingly with that info. Presumably land lines can still work in these areas so emergency communication is still possible.

    “The Wireless Communications Act of 1934 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.”

    The FCC maintains that once it has granted a license for the use of specific frequencies, it is not within the purview of privately owned businesses to thwart their transmission for any reason, or by any method. Completely enforceable? Not likely. But I’ll not patronize any business that actively or passively blocks cell reception, and I’ll wager that I’m not alone. Let the market forces prevail, my friends, and we’ll see who’s got the most financial juice these days; the Luddites or the Technophiles.
