Cell-Phone Wars 992
Makarand writes "According to this article in the Houston Chronicle people
fed up with cell phone chatter have declared
war against cell phones.
They are arming themselves with detectors, jammers and other gizmos to defend privacy,
security, sanity and blissful silence. Although jamming cell phones is not
legal in the US, pocket-sized jammers are available online and even on
eBay. Cell-phone jammers typically work by disrupting
the communication between handsets and cellular towers
by flooding an area with interference
or selectively blocking signals by broadcasting on frequencies
used by these phones. The FCC
has received very few complaints about jammed cell phones
and has never taken action against anyone for that violation."
