The U.S. has more than 5.6 million commercial buildings; very few provide adequate First Responder communications.
National Fire Protection Agency (NFPA) and International Fire Consultants (IFC) set the standards for in-building wireless communications that many states are requiring for new and existing venues. This includes NFPA 72, 2016 code.
First Responders must be able to communicate into buildings from the outside; with each other while inside buildings; and with their command centers outside buildings while they are responding to an incident. First Responders also need access to data, which informs them of the emergency.
People inside buildings must be able to call 911 and receive information.
In-building wireless communication systems bring the two-way radio signal inside buildings and allow First Responders to communicate with each other, particularly in areas of refuge in emergencies.
