Unique 3D In-Building Coverage Mapping Solution

The role of enforcing in-building public safety needs (e.g., # occupants in a room) typically falls to the local fire marshal’s staff. They rely on building codes and standards from the National Fire Protection Association (NFPA). Wireless communications standards are covered under NFPA 72 and NFPA 1221. Both standards prescribe periodic measurements to assure communications.

Historically, public safety communications were mostly based on powerful, external high site transmitters to supply sufficient signal levels to reach into buildings. Modern energy efficient building construction and increasing reliance on anytime, anywhere communications are causing installation of public safety radio enhancement systems. These systems, known in the technical community as Distributed Antenna Systems (DAS) take the external high site signals, amplify them and evenly distribute the signals throughout the building.
