In recent times across North America, there has been an imperative to improve the signaling for cellular phones and for public safety radio communications in buildings.
Often in certain areas of large buildings, cell phones do not work or do public safety radios. What does that mean? In a worst-case scenario, it means people cannot use their phone to call for help. It means that police officers responding to calls in some schools, or firefighters in a stairwell of a commercial building, cannot communicate via their hand-held radios.
