Modern architecture of innovative buildings includes employing state of the art materials to optimise energy efficiency. The usage of thermal insulation glass brought along a reduction of the signal transmissibility and created difficulties for smart phone usage inside a building. We propose a solution using an intelligent surface on removable films. A technology of frequency selective surface (FSS) improves the transmission of the signal at multiple cellular frequencies. The FSS motives are printed on a plastic substrate using conductive inks. The transmission is improving by 15dB allowing mobile communication once the film is simply put on the inside of the window.
