Blocking cell signals can be legal
 
Mostly one sea-lawyer's rant in this group, was that it is illegal to
interfere with any radio signal, etc. That opinion is absent of
understanding the intent of that law, or where it may be applied.

On private property, one may install any device, counter-signal, shielding,
etc that prevent or otherwise render inoperable any other signal that enters
or tries to leave that property. There are reasonable exceptions, before the
crazies ask what about a 1,000' balloon with radar reflector in your
airspace right next to an airport. Get real. We're talking about a
restaurant owner's right to make his interior airspace incompatible with
cellular signals, and nobody can argue he doesn't have the right to do that,
with or without notifying you of it. It's a courtesy if he tells you, tough
luck if he doesn't.

Similarly, the government regulates and (tries) to ensure the operability of
public communications while mitigating unnecessary or malicious
interference. Neither apply to a private property owner's right to have
cell-phone signals blocked on his property. If he invites the public, some
states might pass laws to require he notifies the public of that blockage,
but neither is it the public's right to assume that is so. A locality could
also decide it will prevent cell signals during any venue that takes place
on property it owns or leases. It's reasonable, it's "legal", and it's
happening. Before long, somebody will concoct a way to beat those blockers,
probably by a jam-resistant receiver card that plugs into the phone's
antenna. Then you'll have to check your gun and your cellphone with the
maitri d'. ;-)

I heard a story that in Australia's government house there are wide band
jammers or large amounts of shielding installed so that mobile phones
will not "go off" in the senate and house of reps chambers.

Note that this would contravene the laws in Autralia on jamming devices.

If that isnt an endorsment nothing is!

Hi Bob,

For sure, the government that regulates can use selective enforcement
however it chooses. In the U.S., the Federal Communications Commission
probably makes it difficult to get type-acceptance for manufacture and sale
of equipment designed to "jam" signals, and properly so. The cell phone
industry has a decided interest in preventing widespread usage of devices
designed to imperil their equipment performance. Using such a device on
private property may be fine, if it does not interfere with signals outside
the premises. But obtaining one in the first place will be difficult.

In the USA, deployment of any "Active" device that transmits any

It doesn't help to reference code not properly cited. Then consider how the
U.S. Attorney General (pick your year of political flavor) decides that the
government will interpret specific circumstances of every federal case that
is not well supported by existing case law.

Some broad-reaching statements exist in most federal statutes that cannot be
applied to any individual circumstance, and broad language such as you
paraphrased is not appropriate here either. The Federal government has never
prosecuted anyone for jamming cellphone signals on private property, and
probably never will. The FCC might confiscate equipment that was in the act
of being illegally imported, illegally sold, used maliciously, or used for
profit against individuals or the public. It's a different animal on private
property, which you could learn something about before you rattle off
statutes again. Unless there was a clear case of a property owner's
interference outside the bounds of his property, there is no language in
that monsterous animal of the Communications Act of 1933 that empowers the
government to affect what you do on and "only on" your property with radio
signals. Other laws would apply to something obtained illegally and are not
the topic of discussion here.

Actually, Title 47, Part 15, specifically allows unlicensed intentional
emissions. For example, in the AM broadcast band:



TITLE 47--TELECOMMUNICATION

CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION

PART 15--RADIO FREQUENCY DEVICES--Table of Contents

Subpart C--Intentional Radiators

Sec. 15.219 Operation in the band 510-1705 kHz.

(a) The total input power to the final radio frequency stage
(exclusive of filament or heater power) shall not exceed 100 milliwatts.
(b) The total length of the transmission line, antenna and ground
lead (if used) shall not exceed 3 meters.
(c) All emissions below 510 kHz or above 1705 kHz shall be
attenuated at least 20 dB below the level of the unmodulated carrier.
Determination of compliance with the 20 dB attenuation specification may
be based on measurements at the intentional radiator's antenna output
terminal unless the intentional radiator uses a permanently attached
antenna, in which case compliance shall be deomonstrated by measuring
the radiated emissions.


This is only an example. Most of the spectrum is available for unlicensed
operation at low power, with some frequencies having higher emission limits
than others. Therefore, intentional unlicensed emissions are allowed by US
regulations. Read Part 15.

True. However, Part 15 also states:

(b) Operation of an intentional, unintentional, or incidental
radiator is subject to the conditions that no harmful interference is

the operation of an authorized radio station, by another intentional

(c) The operator of a radio frequency device shall be required to
cease operating the device upon notification by a Commission
representative that the device is causing harmful interference.
Operation shall not resume until the condition causing the harmful
interference has been corrected.

It seems to me that the "no harmful interference" clause would
put cellphone jammers outside the bounds of operation under Part 15.

As far as cellphone use on private property goes... it's certainly
within a property owner's right to declare, and enforce a "no
cellphone use" policy on that property. I cheer every time I see such
a notice.

It's also almost certainly within a property owner's right to include
some sort of perimeter/periphery shielding (passive, nonradiating
interference) to block cellphone signals from entering the property.

It's questionable, to me, whether the property owner would be able to
get away with using an active interferer, such as a jamming
transmitter. The user _might_ win in court, if it could be shown that
the jamming signal was strictly limited to the private property in
question. However, if enough of the jamming signal left the area to
[1] violate the radiated-power limits in Part 15, or [2] result in any
interference with cellphone use as little as a foot outside the
property line, the property owner would probably lose (IMO).

To keep the jamming signal strictly within the property lines, you'd
probably have to Faraday-shield the whole building... at which point
you probably wouldn't need the jamming transmitter.

If you should intentionally jam or cause a cell phone not to operate

probably win. Regardless of what federal laws are or are not violated.

No argument from me on that point. I was merely addressing the broad

not permitted. I was not implying that is okay to interfere with cellular
operation or, for that matter, any other service.

Ed,

Don't mistake my comments as inviting anyone to break the law. But also
avoid the trap of thinking that permission from the government is required
in order for you to act.

I've noticed that good Amateur Radio operators behave in a most responsible
fashion, proud of the responsiblity and mindful of the consequences of radio
operation. But the word priviledge is something reserved for a
self-regulated hobby like amateur radio, not the law. The law and the
constitution do not grant citizens "priviledges".

In a previous part of this thread a member already gave the example of
intentional radiators (low power) allowed. If that (part 15 ?) exemption was
not there, it would still not make the force of law any more permissable for
government to interfere with the rights of a property owner, as long as (he)
was not harming interstate commerce, which is the currently used
(wider-than-hell and not always defendable) definition for every new
encroachment on our Constitution. Patriot act definitions will probably not
survive long enough to be tried in a court, but if they were the standard,
even the rumour that you were thinking about signals would subject you to a
search.

Roger Halstead March 21st 04 01:40 AM

Remember blocking and jamming are different.

I think you will find that the cell phone companies and thus the
government can block any group of numbers or specific repeaters
easily.

Cell phones do not talk to each other directly so interrupting service
should be a relatively easy matter as far as those with the know how
and authority to do so.

I would think it would be very much like blocking, or black holing a
group of IPs at, or through a specific location or locations.

I won't take your statements as anything but ignorance. Have you
successfully trained a radio wave to stop at your property line? It has been
stated on here before (though you probably don't read anything that might
make you look stupid) that any device of sufficient power to jam a cellphone
is not going to be contained within the boundaries of your property line
unless shielded to the point that it would be a waste of time as nothing
could get in either. A part 15 device is not going to have the power to be
effective, and if you up the power level, it is no longer considered a part
15 device. If you think the FCC doesn't enforce these rules, I invite you to

I won't take your statements as anything but ignorance. Have you
successfully trained a radio wave to stop at your property line? It has

been
stated on here before (though you probably don't read anything that might
make you look stupid) that any device of sufficient power to jam a

cellphone
is not going to be contained within the boundaries of your property line
unless shielded to the point that it would be a waste of time as nothing
could get in either. A part 15 device is not going to have the power to be
effective, and if you up the power level, it is no longer considered a

part
15 device. If you think the FCC doesn't enforce these rules, I invite you

to
build your little problem maker and test your idea. Be aware that

Since your deck of know-how comes from reading in these groups, it's a shame
that reading is so fundamentaly difficult for some people. So read more
carefully, please.

Once more, for the slow ones:

The FCC has never prosecuted anyone for blocking cellphone signals on
private property.

Probably the reason that intelligent people put up with so many hacks in
these groups is, in between great exchange of ideas and information,
sometimes it's fun to watch arguments like yours built on wax, and see them
melt into a puddle of no-return on the floor.

No business owner needs to worry about finding equipment to block my phone
anyway. Unlike the rude masses that the devices are needed for, if asked not
to use a cellphone, mine goes "off"

Your getting desperate. Now you're making claims about things you know
nothing about (actually, more that you know nothing about). My knowledge of
this subject is far deeper than yours ever will be and the fact that I read
this group simply proves that I read this group. Are you saying that
participation in a news group implies lack of knowledge? I am not going to
post my qualifications. I don't have to. The ridiculous statements you
continue to make show you to be the ignorant one. I think it's about time I
simply plonk you as it is becoming increasingly obvious that I am arguing
with an idiot. I have better things to do.

You're an antagonist across every board, everywhere you go. Nobody cares
abut the radio experience you have if you choose to fight about everything
outside your experience and education. Your understanding of the law is
comical. Or it would be funny if you weren't such a cantankerous old crotch
that thinks his 8th grade social studies level of knowledge is meaningful in
the business world. Everybody has something to contribute here, but nobody
that acts like a wise guy when they can't cite law, read law, understand
law, quote correctly from the same newsgroup thread, or keep a train of
thought in a discussion can fool anyone about their knowledge level.

Sorry to the group that I was lured into the path so many were with CW, that
of assuming the years of radio operations would translate into meaningful
interaction with other people.

73's,

You should avoid the trap of thinking, since you are a good guy and a ham
and a citizen, that you have any right to emit electromagnetic energy.

Your
government has seen fit to enact legal restrictions on emission of
electromagnetic energy, over a broad frequency range. Perhaps you think

you
have some inalienable right to emit as you please; if so, you are placing
yourself in a bizarre legal area usually inhabited by the kooks who claim
that the Federal income tax is illegal.

First, let's address rights. Our Constitution says nothing about
electromagnetic energy. However, it does authorize the Federal government

to
regulate interstate commerce. The Communications Act of 1934 clearly
identifies the electromagnetic spectrum to be a national resource, usable
for commerce, and by the physics of the medium, quite certainly

interstate.
If you don't agree with that, then vote the rascals out! But be aware that
there seems to be an infinite supply of rascals!

So, now that the Feds are in control of the spectrum, they proceed to
authorize specific and limited usage of that national resource. The Feds
call this Licensing and Authorizing. Notice how this keeps "title"

reserved
to the Feds? You only get what they allow you; you have no "right" to the
resource.

To ease the policing requirements, the FCC allows certain unlicensed
emitters. And they don't meddle, so long as violators of the privilege are
not egregious. OTOH, as the IRS demonstrates every year, compliance by
intimidation really works. Abuse your privilege, by use of higher power,
bigger antennas, operation in a guarded frequency (not even low power Part
15 emitters may emit on emergency or certain satellite and research
frequencies), or by harming a licensed service in any way, and you will be
squashed flat by the majesty of the Federal bureaucracy.

Now, it's my opinion that a property owner has the right to control his
property in such a way as to exclude external electromagnetic energy. I

also
think he has the obligation to warn everyone that he allows onto his
property that he is doing said exclusion. However, when your property is
used by the general public (a theater, a golf course, a stadium), then you
must realize that exercise of your rights is often guided and constrained

by
Federal law. Currently, I don't think there is any Federal regulation that
addresses exclusion of EM energy from quasi-public locations. So that

means
that case law will be created by nasty (and sometimes minutely absurd)
lawsuits probing the boundaries and limits of what you can and can't do.
Opine all you wish, but, unless you like to bleed, you don't want to be on
the cutting edge of this procedure.

Very well said, and I'm on the same page with you in all respects, save for
the minor point of duty to inform. As you also reminded us, that duty would
be driven more by avoidance of civil action but makes it just as important
for a business to comply with. I also mentioned earlier that some (most?)
States could or would pass laws requiring that duty.

Best regards,

Jack
