Makes walls more transparent to signals

Boffins at the Vienna University of Technology (TU Wien) and the University of Rennes have discovered a new method that allows Wi-Fi signals to penetrate walls more effectively.

Currently, Wi-Fi signals reflect off or are absorbed into solid walls, which limits their range and the quality of the transmission. But the boffins created a method which ‘calculates’ an anti-reflective invisible structure to a solid wall, that allows the signal to pass through without disruption.

The tech is similar to the anti-reflective coating on your pair of glasses. If you add an extra layer to the surface of the glasses, light waves can pass better to your eyes than before the reflection is reduced.
