Faraday cages only work when the door is completely shut (I used to do research inside one). Does this idiot not understand that people continuously entering and leaving a store defeats the concept?

Unless people are holding it open non-stop I can't imagine you'd get good enough reception to complete a phone call.  Maybe shout a random word or two, but a whole conversation?

NO. We need new technology to defeat the technology that we already have. More technology is always the solution, can't you see? You will be assimilated, or else. We have the technology to make you see better than you did before. Do not resist.

I've considered opening a bar under the same basic concept, but with no electronics at all within the "inner sanctum".  Would need some sort of revolving door to avoid the leakage issue, and fiberoptics for lighting.

As far as "turn it off".  Some carriers provide a different message to callers when the phone is switched off as opposed to simple being unreachable, but you can achieve the same effect by putting your handset into a $5 Faraday bag as by sitting in this cage.   Not all phones have a battery you can pull, and when you do, some take forever to boot back up when you want it to work again.

I suspect the experience is less about your phone having no reception, than about the phones of the people sitting around you having no reception.  I hate when I'm trying to enjoy my first espresso of the morning and I am surrounded by yammering ninnies shouting into their Bluetooth headsets about their personal problems.

JosephFinn: So how do you disable one of these asshole Faraday cages?


Short answer : you can't. It is a physical part of the structure you are in.

The fcc website has nothing that says passive interruption of a cellular or other signal is illegal, whether done deliberately or accidentally, yet.

Jamming of any type of narrow  or broadcast signal, phone or otherwise, has been illegal since 1934.
The law has been updated over the years to include all new types of signals as they become available.

This applies to things such as deception repeaters , agc capturing devices,  chaff, etc, as well as white noise jammers.

Basically if you do anything to deliberately interfere with the signal that requires any kind of emission on your end, you need government permission before hand.
see http://www.fcc.gov/blog/jammin-hit-bob-marley-miss-communications  for the basics.

When I was an electronic warfare spec in the military, we were told that active jamming of radars and / or comms could be considered an act of war and we could be legally shot at for it.

"You can come for a coffee, you can hang out in a cage, have a chat with people, put your phone away, not have to worry about it buzzing or making any noises while you're here," said Julien Thomas, the Vancouver artist who designed the café.

A coffee shop for people with broken power switches on their phones? If you don't want to be bothered, TURN YOUR PHONE OFF.

Now, I do understand the concept of this for people who do not want to be bothered by the phones of other people.

You do realize your genius idea would probably get you killed quicker because people would be so busy trying to figure out why their phone connection died and trying to re-send texts or re-call someone at 70 MPH that they would be more likely to cause an accident that if they were just able to go about their business, right?

The Japanese are working on such a paint iirc.
And yes the wire mesh behind the stucco on the outside of our house can act as a farday cage, as long as it is grounded in some way.
That's one of the reasons you get different reception quality in different rooms in some houses.
Plumbing ,metal studs, etc. can also affect reception.

I wouldn't recommend jamming a drivers phone for the reasons above.

They would freak out and lose all concentration on the road, guaranteed.

I once witnessed an accident where a car got rear ended.
The driver in the rear car dropped a bottle of soda on his floor and ducked down below the dash to retrieve it.
The car in front slowed down to make a turn at the same time and boom.
We heard the impact and looked over in time to see the rear driver lift his head to see wtf happened.
For a second or two until then it looked like the car was empty.

Depends on the desired form of communication and the construction.

You could it as a large antenna.

And depending on the construction a single mesh of a given size doesn't block all frequencies.

And jamming/interference is definitely a different story.

Cages are very legal and some companies will secure their buildings with them; piping all communications through internal and monitored towers and hotspots.
