In order to ensure radio communication in large buildings a special type of radio repeater is the solution of choice. Required by law, property owners or the respective operators of buildings are obliged in many countries to provide such communication free of charge to first responders, i.e. fire fighters, police and emergency services. This applies to all important and large objects, including but not limited to, office buildings, train stations, airports and tunnels, without coverage by the transmitter serving the area.

Many countries still require analog in-building radio coverage. However, those countries already having launched TETRA public safety radio networks more and more have a demand for digital in-building solutions.

The analog SAFIR+ series of repeater products and the digital SAFIR-T solution from RADIODATA both provide secure communication between mobile users and thus supporting first responders in case of an incident, helping to avoid that lives and property are at stake.
