They're trying to build something that can detect when GPS is on, to protect against phones secretly recording their owners' locations even while in airplane mode.
If it were me, though, I'd just drop the phone into a potato-chip bag.

I wonder if anyone has independently tested these for emissions leakage. https://www.amazon.com/Faraday-EMP-BLACKOUT®-Prepping-Smartphones/dp/B01BCV7JMW/ref=sr_1_1?ie=UTF8&qid=1472230252&sr=8-1&keywords=faraday+cage+emp+bag+from+blackout+bags https://www.amazon.com/Faraday-EMP-BLACKOUT®-Prepping-Smartp...
- dnh44 10y agoThose look remarkably like some anti-static bags that we bought by the thousands in China for less than a dollar a piece. I'll check on Tuesday and post back here.
- gjkood 10y agoI just spent a week in the Shenzhen Huaqiang Bei electronic malls and I couldn't agree with you more about the pricing. You can do so much better being there physically and negotiating the hell out of things.
- dnh44 10y agoWell I've tried the bags we have at the office and while they do indeed look the same my phone has no trouble staying connected while inside the bag.
- duskwuff 10y agoRead the reviews. Multiple users report cell phones working perfectly fine while inside the bag. As noted by dnh44, these are almost certainly bog-standard antistatic bags, which are not intended to provide any kind of RF shielding.
- gjkood 10y agoAs all things we buy on the internet, if it seems to be too good to be true... Hence my comment about independent testing/review of such products. However the concept of Faraday Cages is not new. There are vendors catering to the Law Enforcement market that make these bags to prevent tampering of evidence on confiscated devices. You just have to find the right ones. I was just showing examples of such products available online. Caveat Emptor.
- krastanov 10y agoGPS locators are passive: only receiving signals, not emitting them.

- johansch 10y agoYou can't really get massive global PR with a potato-chip bag though.

- Theodores 10y agoThe potato chip bag option would have plausible deniability. I would go for a whole lunch bag with sandwich in genuine tin foil as mylar film doesn't seem that thick to me. Plausible deniability is really important if one expects to be frisked. Traveling in something like cycling gear could be part of the disguise, you can go through special gates at train stations and not be ticket inspected by machine. Nobody expects the guy in fluorescent clothing travelling at 15 mph.
