Question. Don't we have the technology to block cell phone and other comms from the hearing room?

[Midnight Writer]

In addition to banning phones from the Secure Room, can't we simply block signal transmissions?

1. Good question.

2. Blocking transmissions doesn't stop...

someone from just taking pictures, notes or recordings then distributing them later when they can upload.

3. Even if they block the cell signal, it can still

be used as a recording device.

4. I think the phones will still function to record and take pictures

The transmissions could still resume as soon as they were outside the blocking. I think this happens in hospital areas where sensitive equipment is used.
Am I correct?

6. I had not considered medical devices like pacemakers. I think they need to communicate.

11. Possibly

But from what I understand that data is not lost.

5. It just takes super thick walls, I think

Have you ever noticed that your cell phone often doesn’t work in a hospital? It’s because their walls are unusually thick and strong.

7. They do more than that. It is basically a Faraday Cage...

where radio waves are actively attenuated with metal mesh screens. Generally they'll have scanners to detect any transmissions originating in the room.

But like was said above, since modern phones are basically videocams, the ability to surreptitiously record the proceedings exists.

10. No, there is a conductive material in the walls

The origin of the term "tinfoil hat" comes from people who have learned that "they" can't remotely screw with your brainwaves so long as your brain is encased in a conductive shell.

8. Yes.

9. You can make a room into a kind of Faraday cage that blocks transmissions, but

those aren't the problem so much as photographs and recordings that can be taken out of the room.
