How Rude! Do you think that I would actually give you a lecture or
legal opinion simply based on your innocent sounding question? ...
Hell Yes, I Would - and if needed, I'll do it again, whether you ask
or not. It would be far worse if nobody had the courage to speak up.
I refer you first to the FCC Regulations on the subject, quoted and
referenced at the bottom of the reply. There is a VERY GOOD REASON
why nobody sells or imports jamming devices like that into the United
States, because they are very illegal.
I would strongly suggest you drop all thoughts as to buying or
installing them. It would be a fun device to keep people from making
or receiving cell calls and interrupting your City Council meetings.
But let's say someone has a heart attack while alone in a stall in the
public restroom right outside the Council Chambers, and they die while
trying to call 911 for help from their jammed cellphone. The minute
someone figures it out (and with CSI and NCIS giving people pointers
on where to look, someone will check the phone and see the failed
calls in the Outgoing Calls log) I guarantee you that all holy hell is
going to break loose.
Or there is a disturbance in the Council Chambers, and a local
policeman is delayed in making his radio call for backup and
assistance. Or a commercial airplane making an instrument approach
into the local airport in bad weather or heavy fog is 1/4 mile from
the runway, and suddenly sees his whole instrument landing beacon
system go blank ...
The type jammers used for this service are not very selective, they
will wipe out all communications over a broad spectrum of radio
frequencies and services including commercial, industrial, public
safety, and aeronautic services, not just the narrow segments serving
cellular telephone communications.
And if you are worried about bugging or malicious transmissions, you
are just going to have to hire an expert to actively sweep for them.
They can be anywhere in the electromagnetic spectrum, from DC to
light, and a cellular jammer will probably miss the intended target.
