When their phone is smarter than they are... well.. there you go. 

i wonder how many of them actually get busted via their own on line posted videos.    Funny as hell 

[LeoG]

This guy might have busted himself

This guy definitely did, with a smile on his face at that.

Apparently people rat themselves out via social media pretty frequently. You'd think they'd know better after a few of them got busted, but they keep doing it.

if you put your phone on airplane mode will the cell tower be able to ping your phone

Yes, a cell tower can still ping a phone even when it's in airplane mode. Airplane mode primarily disables cellular radio for calls, texts, and data, but it doesn't stop the phone from periodically checking in with nearby networks. This "pinging" can still allow for tracking or monitoring.

Here's why:

• Airplane mode is a phone setting, not a network setting: Airplane mode affects the phone's ability to communicate, but it doesn't prevent the network from detecting the phone.

• Periodic pings: Even in airplane mode, the phone may still periodically check in with cell towers to maintain its registration with the network.
• GPS and location services: Airplane mode doesn't turn off GPS, which can still be used for tracking.
• Therefore, while airplane mode can help prevent direct calls, texts, and data usage, it's not a foolproof method to avoid being tracked or monitored by networks.

Yes this is correct, the continuous pinging was put into effect back in mid 90's early 2000's for the purpose of 911 being able to get your location if you were calling for help.  The only way to stop it is to take your battery out. even powering it off will still send an LNL(last known location) ping just before its fully off.

If you use FB on your phone its tracking you as well, Google maps keep track of your locations as well.

So, if I turn my phone off at my home, it won't be detectable again until I turn it back on?

Only if you remove the battery.

Not that I'm planning to participate in any crimes, but it seems the best solution is just to leave it at home. If they did that, FRS radios could certainly be handy for coordination.

[LeoG]

If you leave it at home you have an alibi also.  I was home, check my ping...

our stick your phone in a Faraday Bag

Not all faraday bags are created equal. Better double up on them if using cheap bags from Amazon or eBay. Or stick them in a faraday bag and then into an all metal container.

i would defiantly go with a military grade faraday bag.  Ebay & Amazon would be the last place i would go to buy one,,

What would be a good source?

[WRUE951]

 i have some from Nest that claims to be military grade.  Big enough to hold a HT with antenna.   These are more designed for EMT protection with i would think would work against cell phone detection.  

[AdmiralCochrane]

I have a metal box with overlap and metal taped edges that my vehicle still detects the fob thru.  The chip signal amplifiers are pretty strong.  For improved security I took the battery out of the fob and now the chip has to be within a half inch of the start button.

now you got me thinking..  Tomorrow i'll break one out stick my HT in one and see if i can talk with  it from an other radio..

Let us know how that goes.

[SteveShannon]

The higher the frequency the shorter the wavelength and the smaller the opening that can penetrate. 

[LeoG]

Probably why an EMP bag will let high frequencies through at strong signal levels.  The bags are designed for a dc generated pulse.

[WRYZ926]

Microwave ovens are faraday cages. You can always put your phone into a faraday bag and then into a microwave. I don't suggest turning the microwave on while the phone or bag are inside. 

Faraday clothe, just like any other type of clothe, will have holes in the weave which will let some RF pass through. Ideally one would want to use the tightest weave faraday clothe and place that inside a metal container.

Ideally one would remove the battery also. But most modern smart phones do not have removable batteries without having to disassemble the phone.

O,K. The bag works fairly well, Put both cell phone and my Hytera HT in the bag.  Tried calling my cell phone, no ring, straight to voice mail. So i'm assuming the cell phone is protected.   The HT???,,  Within a few feet of the bag i can break the squelch with another radio, 20-30 feet away, no go.  My guess, the bag is supressing 50-60 dB of signal.   Would be interesitng to take the bag with cell phone in close proximity of a cell tower to see what it does.. Maybe someday, but right now, gonna go grab some breakfast.  

[AdmiralCochrane]

Well thought out

[LeoG]

Cell phones work very well at -107dBm and OK at -115dBm and at -120dBm it's getting iffy.  So a 50-60dB drop may not be enough in a lot of situations.  But you'd have to be pretty close to the cell tower for it not to go below -120dBm in the bag.  A -60dBm cell signal is usually right on top of the cell tower.

yea, couple hours ago i was goinna take a drive by a couple cell towers to do close proximity test, but the damn beer won my attention
