FF-SIGNAL carries networks powerfully through structures
The FF-SIGNAL signal amplifier is an innovative passive element that relays signals while also isolating against 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 targets.
The signal amplifier is installed inside the structures, e.g., in between window frames or under the plastering of a concrete wall. The product is developed and made in Finland by partners Finnfoam Oy and StealthCase Oy.
The starting point of product development
Modern construction solutions pose challenges for mobile networks. In a brand new modern block of flats, for example, the energy efficiency of windows can be so good that the balcony might be the only place where you can reliably use wireless devices. Problems also arise in old buildings that have been renovated and fitted with new windows.
Concrete structures, windows with selective coating and other construction products that contain metal are especially disruptive for signals. As energy efficiency requirements become more stringent, the design of buildings should ensure the adequate indoor reception of networks that are crucial for building safety. FF-SIGNAL is designed to solve reception issues in these new and challenging conditions.
Operation and technical data
FF-SIGNAL receives the incoming signal from a base station and relays the signal through the wall along its entire length and thus maintains the strength of the outdoor signal inside the apartment. The FF-SIGNAL amplifier works both ways, also from indoors to outdoors. The signal relaying ability of the FF-SIGNAL element has been measured and tested in laboratory conditions and confirmed in various field tests.
FF-SIGNAL consists of two FF-PIR (polyisocyanurate) insulator sheets (20 mm) manufactured by Finnfoam Oy and a signal amplifier or antenna element that is placed between them.
- No heat bridge
- CE certified
- Best indoor air quality class M1
- Patented solution
- Does not require electricity
- Works with networks of all operators
- Supports most common IoT technologies
- As it is a separate solution, windows can be purchased freely and separately
Dimensions of an FF-SIGNAL element:
Size: 200 x 1 200 mm and 300 x 1 200 mm
FF-SIGNAL can withstand UV radiation during construction, but it needs to be protected from UV radiation in long-term storage. Before installation, the FF-SIGNAL amplifier is to be stored at the construction site protected from weather.
FF-SIGNAL requires no maintenance and it will work inside the wall of a building for decades, which makes the passive FF-SIGNAL an extremely competitive solution for reception problems over its lifecycle when compared to retrofit solutions.

FF-SIGNAL throughput dampening
FF-SIGNAL's throughput dampening is really low and always remains below the limit defined/recommended for structures by operators (-15 dB) to ensure the operation of their networks. Usually the dampening effect of today's structures falls between -30 and -70 dB.
