The speaker mentions this as another habit retained from his service. He references solutions developed at the Wojskowa Akademia Techniczna (Military University of Technology) that specializes in protecting telecommunications devices. The concept is simple: a container that functions as a Faraday cage — you put the phone in, and it completely disappears from the network. After the conversation, you can retrieve it. This is a practical security measure against the reality that phones can be used as remote listening devices even when apparently powered off.
A Faraday cage is a conductive enclosure that blocks electromagnetic fields. When a phone is placed inside, it cannot receive or transmit any signals — cellular, WiFi, Bluetooth, or GPS. The phone effectively ceases to exist on any network.
The speaker mentions this as a personal practice retained from his service, referencing Polish-developed solutions from WAT.
Well, there are very simple containers for putting in — the phone disappears, simply. It's gone, but then you can recover it. I understand that for the duration of the conversation, the phone simply isn't there, it disappears from the network entirely — a Faraday cage.
