The FF-SIGNAL signal amplifier element is an innovative, signal-relaying passive element that also provides insulation against the cold and moisture. A mobile phone signal passing through wall structures is 30–100 times stronger when relayed through the amplifier, which enables fast and reliable connections indoors even in challenging settings.

The signal amplifier is installed inside the structure, e.g., in between window frames or under thin-coat render on a concrete wall.
