The First Responder Network Authority (FirstNet Authority) recently partnered with the Major County Sheriffs of America (MCSA) to run trials on two new technologies: Z-Axis for FirstNet and FirstNet Push-To-Talk.
FirstNet Authority, an independent agency of the U.S. Department of Commerce’s National Telecommunications and Information Administration (NTIA), oversees FirstNet, the national communications network for emergency responders and the public safety community.
The trials of both technologies were run with on-the-job first responders to test the technologies’ real-world usability and determine any needed adjustments and upgrades. Due to necessarily secure cellular and Wi-Fi coverage inside of many U.S. jails, the sheriffs’ offices that tested the technologies noted that intra-campus communications can be a challenge.
The trials ran for at least two weeks each. The five MCSA agencies that participated had teams of up to 10 people, including court security, administrative staff, deputies, and supervisors. Each agency found the technologies useful and rife with opportunities to improve daily operations, while noting possible improvements and new uses, according to a FirstNet Authority blog post.
Using a sensor built into many smart phones, Z-Axis for FirstNet can be integrated into an app to display the vertical location of a first responder in a building with multiple stories.
The Z-Axis trials exhibited increased capability to track real-time personnel location, especially in areas without camera coverage. The agencies also proposed the usefulness of the technology in transporting prisoners to court either in vehicles or when walking through underground locations, tracking vans for work release, court, and community work programs, and serving papers in multistory buildings. Suggested improvements included a more consistent calibration and frequency process.
FirstNet Push-To-Talk allows first responders to use their smartphones to connect and communicate instantaneously with individuals and groups, including optional integrated land-mobile radio systems.
The agency teams in the trial saw the technology ensure real-time information exchange, increase location reporting, and improve situational awareness. The proposed additional uses for the technology included discreet real-time intra-team updates for warrant and intelligence officers, strategic inconspicuous communications for surveillance teams, and communications for non-emergency agencies like public works. They also noted that it would be cost effective, as 50 smartphones can be purchased for the price of one radio. Suggested improvements included streamlining who can create talking groups, setting a time limit for formed groups, and live video streaming.
