Through-Wall Human Pose Estimation Using Radio Signals
I've noticed, recently, that literally every major chain store I go into blocks my cell signal. I get full bars outside, perfect LTE, and about 5 ft past the glass doors, I'm suddenly cut off. Specifically, Meijer grocery stores and Home Depot are the worst offenders. Coincidentally they offer free in store WiFi to track me with, so I turn off my wifi radio on both smartphone and smartwatch before walking in the door... Note, this was not the case in the exact same physical stores a couple years ago, and they weren't closed for remodeling in the interim.Does anyone know if this sort of Faraday cage technology for large buildings is easily available for me to install in my own home? If so, what's it called, what does it cost and where do I get it?
