WiFi Paint – Stops your neighbour stealing your WiFi
|
A bunch of Japanese scientists at the University of Tokyo have invented a new paint, that is designed to block high frequency electromagnetic waves.
Whilst the technology is not new, previous paints were unable to block WiFi signals as the frequency was too high, but this new paint uses a brand new aluminum oxide that is capable of blocking higher frequency waves, like the ones in WiFi Signals.
