“If it cant transmit or receive it cant be remotely turned on.”
They can listen through your cell phone unless you’ve taken the battery out. The phone being on/off or in sleep mode is controlled through software.
That will drain the capacitors, but the internal batteries will keep powering select functions for quite some time - similar to the CMOS battery in PCs.
I’m assuming the phone has an insulating case, or contacts the conductive wrapping in one place. You don’t need two layers.
If you had conductive contact between the active RF circuitry and the case at two widely separated spots on the case, then you’d defeat the purpose. Still, you don’t need an inner conducting layer.
As a postscript to some other thread comments, in normal operation shielding will run your phone’s battery down in a hurry, because in the absence of a signal, the phone keeps querying to find a cell tower at max power.
In a former life I was an electromagnetic compatibility engineer.
“So, given a particular cell number, how do I log on and listen in?”
You can go through the phone companies systems. Or you can set up a fake cell “tower” which is what many law enforcement agencies do.
IMO the NSA/CIA have backdoors into the cell phones which facilitate this. The GPS chip was forced into every phone for a reason.
On thing people miss is that the item in the cage needs to be isolated from the cage. Maybe that is the the point of your layer of insolation.
The perfect faraday cage would be a sphere. Any other geometry will compromise the effectiveness of the cage.
Yes, that should work I think.
You are missing the point.
Once airplane mode shuts off all communications (receive+transmit) then it cant receive a signal command to do anything, and obviously not to start receiving and transmitting again.
If the purpose of AP mode was just to lower the rate at which the phone goes out but still look for messages then that might make sense. The purpose was to shutdown RF transmissions.
Once contact is enabled then it takes some back and forth ID communications for it to receive and send any real data.
Sprint website says :Airplane mode disables your device's ability to send or receive any type of wireless transmission.

Do you know for a fact that there are small batteries on the circuit boards in a smart phone? If so, how did you come to know it?
I’m waiting for people to put the pieces together
1. ALL your phones is always active
2. your phones are monitored and recorded
understanding HOW #2 works would be key to the bigger picture. there isn’t some smokey room with g-men listening to your every word. no. that’s very 1950s
today, computers analyze your speech converting it to text. that text is then matched against a phrase db to determine the ‘value’ under dozens of categories. if the conversation exceeds a threshold in any category, it is routed to the appropriate dept
now add the fact that ALL available mics are monitored in this way...
your kitchen table conversation at dinner is being recorded and analyzed by those millions of computers
just the facts ma’am
Dang, I called this 12 years ago. I said the next level of hacking will be within the manufacture of the chips. Bam!
Nut-job Conspiracy Theory Ping!
To get onto The Nut-job Conspiracy Theory Ping List you must threaten to report me to the Mods if I dont add you to the list...
This is why the ‘find my Iphone’ app doesnt work when the phone is in Airplane Mode.
Jeeze, I know they seem like magic but...
Here’s a discussion of some of what is still possible in AM:
http://en.wikipedia.org/wiki/Airplane_mode
But further than AM, a phone shut completely off can still be located and more, as I understand it.
“You are missing the point.
Once airplane mode shuts off all communications .”
Does it shut off all communications? Airplane mode and sleep mode are software configuration and not a physical switch. It would be a trivial exercise to activate the audio controls without turning the screen on.
Sprint also said they weren’t giving the govt access to all of our phone calls, but we know they lied.
Its not a question of whether they can do this. Its a question of whether they want to listen to YOUR phone.
CIA is now attempting to "collect everything and hang on to it forever," March 2013
Get it? CIA, not NSA. So you wonder just how many of these databases exist out there?
Monitored through your TV, cell, landline phone, ipad, laptop and any other electronic item.
There was a story a couple months ago about verizon monitoring conversations through the TV so they could tailor advertising based on what people were talking about.
I put my phone in the microwave oven and the refrigerator and was still able to call it.
I recommend trying all the different suggestions proposed and letting us know what is effective.
Taking out the battery was effective.
Already read that wika post:
On locating your phone also see #53
Battery doctor monitors, logs and reports all the Iphone functions use of power and signal transmission is the biggest user, the easiest to check.
Who knows? The inner workings are a black box over which most users have no control.
