<div dir="ltr"><div>Dear Dale,</div><div>The key is to do a REALLY GOOD JOB, with plenty of overlaps, while installing the steel mesh under the stucco in your steel-framed building with 3.5" x 14" steel air ducts between the steel studs, as part of the HVAC system. After spending 25 years on the Bench, I can say that there are ways of dealing with sleazeball lawyers. There are 911-only emergency phones next to the AED wall-mounted devices in all public areas. There's also a rescue cart in the BO.</div><div>/s/ Richard</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jan 28, 2015 at 7:54 PM, Dale Farmer via Stagecraft <span dir="ltr"><<a href="mailto:stagecraft@theatrical.net" target="_blank">stagecraft@theatrical.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>Active RF jamming has long been illegal
in the US except for the military and suchlike. What Marriott
did (handwaving the gory technical details) was have their wifi
nodes detect other wifi nodes that were not in the marriott
network, and any wifi devices that were connected to these.
Marriott nodes then spoofed deauthorization messages to the end
user wifi devices, which then shut down the connection and
restarted a new connection authorization process, which the
marriott wifi nodes detected and did the same thing again. Repeat
ad infinitum. <br>
<br>
Not technically jamming in the traditional sense, more of a
denial of service attack. But the FCC folks looked at it, and
decided that this was, under the intent of the anti-jamming
regulations, just another form of jamming of a legitimate licensed
RF service. <br>
<br>
Building your structure in such a way as to be a faraday cage
is not, I think, illegal under FCC rules. But unless you are
building a bunker, a theater, or other windowless structure,
making it RF proof is actually pretty difficult, especially
against higher frequencies that will slip in through cracks and
seams. IF you are building a structure where you have some
legitimate need to do this, such as classified work that requires
TEMPEST RF blocking, or a RF leakage test chamber. Actually
doing this for a theater would open up another can of worms. <br>
<br>
Your insurance provider may hike your premiums if they find out
your building is a faraday cage. Your local fire department may
also require you to install a fire department radio repeater or
otherwise open up your building to their radio communications.
Any patron who suffers medical incident on your property who
suffers adverse result that could possibly be blamed on lack of
radio service to the EMTs by a sleazeball lawyer will also be
interested. <br><span class="HOEnZb"><font color="#888888">

every business class or higher hotel makes you pay a ridiculous

Weird? <br>
<br>
But this only applies to active RF jamming or "deauthorization?"
of personal Wi-Fi hot spots operating on mobile networks right,
not construction blocking or Wi-Fi jamming.<br>

The FCC released it's ruling on the marriott wifi blocking
matter. WHat they did was essentially jamming, and
anyone else who tries to do this will get "...substantial
monetary penalties."<br>
