FF-Signal

FF-SIGNAL CARRIES NETWORK SIGNALS EFFECTIVELY THROUGH STRUCTURES

The FF-SIGNAL signal amplifier is an innovative passive element that relays signals and insulates the structure 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 settings.

The signal amplifier is installed inside the structure, e.g., in between window frames or under thin-coat render on a concrete wall. The product is developed and manufactured in Finland, in cooperation between Finnfoam Oy and StealthCase Oy.

STARTING POINT FOR 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 adequate indoor reception for networks that are crucial for building safety. FF-SIGNAL was designed to solve reception issues in these new and challenging conditions.

OPERATION AND TECHNICAL SPECIFICATIONS

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 capacity 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 in between them.

FF-SIGNAL

Maintenance-free
No thermal bridging
Rust-proof
CE certified
Certified M1 for best indoor air quality
Patented solution
Does not require electricity to function

Supports the most common IoT technologies
Cost-effective
As the solution is based on a dedicated device, it does not affect the purchase of windows for the building.

DIMENSIONS OF THE FF-SIGNAL ELEMENT:

Size: 200 x 1 200 mm and 300 x 1 200 mm

COST-EFFECTIVENESS

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.

Recipient of the Technology to Products Foundation’s Recognition Award in 2017 – FF-SIGNAL promotes sustainable and productive built environment.

INSERTION LOSS WITH FF-SIGNAL

FF-SIGNAL offers extremely low insertion loss, which remains at all times below the level recommended/specified by operators (-15 dB) to ensure the operation of their networks. The insertion loss of modern structures typically falls between -30…-70 dB.
