RE: TOTAL WIRELESS SECURITY

["Rob Shein" <shoten () starpower net>]

There are FCC regulations that specifically prohibit producing
interference with other devices.  This is why there aren't any radar
jammers for cars, just radar detectors.  The few products that claimed
to be jammers were shown to be little more than reflectors, and bad ones
at that.  Casinos use architectural features to limit emanations (and
inbound energy as well) in conjunction with limited jamming; since the
jamming does not exit the premises of the building, it is not within FCC
jurisdiction.  My neighbor and good friend is on the FCC general
counsel; I just asked her...apparently if it goes outside of a building
it's in their domain.
