INTRODUCTION
During an emergency incident, every minute is critical; first responders need to be able to communicate
with each other inside and outside of any structure at any time. Nextivity's Cel-Fi QUATRA RED for Public
Safety solutions are designed to provide coverage in the most challenging and complicated buildings and
structures to ensure complete-code compliant coverage throughout the facility.
This guide refers to additional tools and resources, such as the Cel-Fi WAVE PRO Mobile app, and the
COMPASS device. This guide does not cover the complete usage of outside tools, but only instructs usage
as it pertains to the QUATRA RED system.
System Overview
Cel-Fi QUATRA RED solution consists of a Network Unit (NU) and up to six (6) Coverage Units (per NU). The
Network Unit takes off-air signals from two available donor antenna ports (LMR and LTE) and digitizes the
RF signals for distribution to up to six Coverage Units (CU) over dedicated Category (Cat5e or better)
cables. CUs convert the digital signals back to RF, boosts them, and transmits from its RF port to provide
public-safety coverage at the location.
NU and CUs must be the same model and band configuration. Multiple QUATRA RED systems can be
installed together to form a more extensive solution. Systems can be attached to a specific site in the
WAVE platform and remotely managed.
Cel-Fi QUATRA RED provides a sophisticated network-safe design that has been engineered to minimize
the embedded effects of signal amplification.
Note: There is no technical limitation to the number of systems or solutions that can be installed together
at a site.
