In-Building Public Safety Communication ERRCS
Solution Including FirstNet

QUATRA RED is designed to provide consistent coverage in the most challenging building structures and to guarantee full compliance with the most current fire codes.

As the public safety community evolves to include cellular LTE support, the QUATRA RED is the only solution that offers true carrier-grade channelized support for FirstNet. Both LMR and LTE aggregated at the head-end, digitally-distributed over Category cable, and retransmitted through a single serving antenna or DAS field.

The Cel-Fi QUATRA RED Class A or Class B 700MHz/800MHz channelized Emergency Responder Radio Communications System (ERRCS) Smart Signal Booster was designed with the needs of First Responders, Building Owners, Installers, and Authorities Having Jurisdiction (AHJs) considered. The QUATRA RED is a complete solution, each component fully-compliant with the current International Fire Code (IFC) and National Fire Protection Association (NFPA) standards.

Cel-Fi QUATRA RED Monitor & Battery Backup Unit

The Monitor and Battery Backup Unit (MBBU) is the central point of the Cel-Fi QUATRA RED system. It provides constant direct current, alarming, monitoring and battery charging capabilities. Integrates a wireless LTE modem and a wired Ethernet port for remote access to all the components via the Cel-Fi WAVE Portal or the WAVE PRO app. Is NEMA 4 rated and UL2524 compliant. Two versions available to optimize power requirements and installation costs.

Cel-Fi QUATRA RED Emergency Power-off Switch

Cel-Fi’s QUATRA RED Emergency Power Off Switch (EPO) can instantaneously shut down the ERRCS solution from a single point to eliminate the risk of combustion caused by electricity or static. Designed to prevent inadvertent operation and can be installed in any location designated by the authority having jurisdiction.

Cel-Fi QUATRA RED Network Unit

The Network Unit (NU) processes FirstNet and LMR off-air signals digitally to provide reliable and interference-free coverage. PoE based architecture and Cel-Fi patented algorithms for automatic setting of uplink and downlink gain, reduces time and cost of installation significantly, making Cel-Fi QUATRA RED the most compelling public safety solution in the market.

Remote Management through WAVE Portal.

Cel-Fi WAVE Portal

Cel-fi WAVE Portal

The Cel-Fi WAVE Platform enables device management and maintenance of Cel-Fi QUATRA systems. The Cel-Fi WAVE Platform mobile app facilitates ease of use on site. Alerts and alarms can be used as configured out of the box or they can be customized however the owner or admin chooses.

The Cel-Fi WAVE Platform is a cloud-based remote management platform that allows users/operators to manage multiple Cel-Fi QUATRA systems. Features of the platform include:

  •  Cel-Fi device and asset management
  • Data modeling and reporting
  • Mobile and computer applications
  • Globally trusted carrier-grade security
  • Users can access the Cel-Fi WAVE Platform portal through the dashboard interface, or integrate it via APIs.
