Wireless communications are mission critical for public safety organizations and first responders. Driven by new applications, interoperability needs, and coverage requirements, public safety communications are facing a complex convergence of technologies, including 4G LTE cellular, 802.11ac Wi-Fi, Land Mobile Radio (LMR), and GPS or other Global Navigation Satellite Systems (GNSS). The next generation of public safety communications equipment must support a wide variety of applications, including live video streaming, situational information, navigation, and asset tracking. Initiatives such as FirstNet’s National Public Safety Broadband Network (NPSBN) in the United States envision widespread adoption of LTE technology to enable these new applications and ensure interoperability between jurisdictions, including those currently using older technologies such as P25. Meanwhile, regulatory agencies worldwide are looking to fill gaps in public safety network coverage, particularly in in-building environments. In the U.S., an increasing number of local jurisdictions are requiring buildings to comply with coverage requirements based on National Fire Protection Association (NFPA) or International Fire Code (IFC) standards.
