What's interesting about the wallpaper is the ability to
block some frequency bands while passing others.
There's been good shielding wallpaper available for ~15 years,
but that's for blocking everything including cellphones and pagers.

A type of wallpaper that prevents Wi-Fi signals escaping from a building
without blocking mobile phone signals has been developed by a British
defence contractor. The technology is designed to stop outsiders gaining
access to a secure network by using Wi-Fi networks casually set up by
workers at the office.
