Police, fire and EMS personnel are frequently called upon to respond to emergencies inside buildings and are often the first to know that a building has poor radio reception. With the tragedies that took place on 9/11, a strong focus has been on providing first responders with reliable radio communications in large buildings. Distributed Antenna Systems (DAS) were designed to extend wireless coverage within structures and enable radios and cell phones to work regardless of their position within the building. For first responders, Distributed Antenna Systems enhance radio signals, which may also make the difference between life and death.
Modern construction techniques and materials often block or degrade internal and external wireless communications. This results in a loss of communication between the first responders, who bravely enter a dangerous building, and their only connection to captains and engineers who are their only source of navigation through an unfamiliar building. First responders, who often rely solely on 3-watt handheld radios, often lose signals in difficult environments, such as elevators, basements, and garages. The installation of emergency communication systems, like DAS, resolves these issues and dangers. These in-building Distributed Antenna Systems are truly a first responder’s lifeline.
The Distributed Antenna Systems consist of an antenna located on the outside of the building that picks up outdoor signals, a bidirectional amplifier that boosts and strengthens the signal, and a passive distributed antenna system that distributes the signal throughout the building.
These systems must be carefully designed to provide the correct signal coverage throughout the entire building. These in-building Distributed Antenna Systems should be engineered and installed by specialists who are competent and experienced in wireless communication.
In 2009, the National Fire Protection Association (NFPA) fire code was updated to offer a technically correct in-building radio system into local fire codes. According to the NFPA, at least 30 states have adopted (or will soon adopt) codes that apply to first responder coverage.
