Need Some Extra Wireless Security at The Hospital – Paint The Place With Anti-Wi-Fi Paint

Of course this sounds like it could uses in many places, such as movie theaters too, quiet those darn phones during a movie. We all go through the time and trouble to bullet proof wireless as best we can, but if the signals did not need to go outside of certain rooms or the entire hospital for that matter, paint the place.
The price certainly is reasonable, biggest cost is labor. If you had selected rooms for screening, surgery, etc. where you wanted some extra blocking power I guess this could work. I wonder how many folks will also begin painting their houses too. BD
It means security-conscious wireless users could block their neighbors from being able to access their home network - without having to set up encryption.
The paint contains an aluminum-iron oxide which resonates at the same frequency as wi-fi - or other radio waves - meaning the airborne data is absorbed and blocked.
By coating an entire room, signals can't get in and, crucially, can't get out.
Developed at the University of Tokyo, the paint could cost as little as £10 per kilogram, researchers say.
"In a medical setting, you could transmit large volumes of data from a medical device, such as an endoscope, to a computer.
Mr Jackson notes that while the paint may block eavesdroppers, it would not prevent other types of hackers or intruders.
"Paint that blocks RF based Wi-Fi transmissions does not in any way remove the need to ensure a robust security model is deployed," he added.
