Researchers at Institut Polytechnique de Grenoble, in cooperation with the Centre Technique du Papier, in France, developed the wall covering, known as metapaper, that can preventing wifi signals from being broadcast beyond the confines of an office or apartment, reports Sean Gallagher for Ars Technica.
The product contains conductive silver ink with metallic patterns. The makers claim it can selectively filter, reduce or reflect electromagnetic waves. It not only protects against intruders stealing wifi from buildings, but it also ensures that signals inside a building are more secure and stronger.
