QUATRA RED Components

QUATRA RED Management Unit

The Cel-Fi QUATRA RED Management Unit (MU) is the central point of the system. In addition to accepting and distributing power from the QUATRA RED Battery Backup Unit (BBU), the MU controls and monitors all system components, including the QUATRA RED Network Unit (NU) and Coverage Unit (CU) as well as Cel-Fi RED Remote Annunciator Panel (RA), Emergency Power-off Switch (EPO), and Active Server Antennas. System performance analytics are available in the Cel-Fi WAVE Portal or WAVE PRO app.

QUATRA RED Network Unit

The head-end of Cel-Fi QUATRA RED installations, the Network Unit (NU) processes and digitizes separate off-air LMR and FirstNet donor signals and distributes those signals to the system’s Coverage Units (CUs). Providing coverage up to 320K ft² per CU, each NU can support and power up to six CUs via scalable PoE architecture.

Optional Components

QUATRA RED Monitor and Battery Backup Unit (MBBU)

The Cel-Fi QUATRA RED Monitor and Battery Backup Unit (MBBU) offers an alternative QUATRA RED configuration that does not require the Management Unit (MU). As an all-in-one component, the MBBU combines the MU’s alarming and monitoring functionality with battery-charging capabilities. In addition to delivering constant direct current to each QUATRA RED component and accessory, the MBBU features an integrated wireless LTE modem that provides remote monitoring and management of all system components via the Cel-Fi WAVE Portal. The unit is also NEMA 4 rated, listed to UL 2524 and available in two size versions for optimizing power requirements and installation cost.

RED Active Server Antenna

The Cel-Fi RED Active Server Antenna is an active multi-frequency, omni-directional antenna for ERCES public safety solutions that require monitoring capabilities at the component level. In addition to being designed for hard cap and false ceilings, the Active Server Antenna features an N-type female connector and rugged IP20 grade electronics. The component is ideal for Cel-Fi QUATRA RED and SOLO RED installations, which provide real-time antenna monitoring capabilities through the WAVE Portal.

Tools and Software


The Cel-Fi COMPASS RED attachment to the Cel-Fi COMPASS enables installers and integrators to perform Site Surveys that will generate Public Safety Reports (which are required by some states). Some setup is needed in the WAVE Portal before the WAVE PRO app can install the Configuration Packages and Calibrate a QUATRA RED system. The app connects directly to the QUATRA RED MBBU via Bluetooth and can also be used to monitor the Radio Data and view the System Status and Alarms.


Cel-Fi WAVE Portal

The Cel-Fi WAVE Portal is a cloud-based remote management platform that enables device management and maintenance of Cel-Fi QUATRA RED systems. The Cel-Fi WAVE platform is designed to also work on mobile phones which facilitates ease of use on site.

More Details

The Cel-Fi QUATRA RED Class A or Class B 700MHz/800MHz channelized Emergency Responder Communications Enhancement System (ERCES) public safety solution 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.

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.

QUATRA RED is the first and only solution in the market that can easily be scaled from a single donor “BDA” deployment at 1 or 2 watts to a full-blown (single donor) “Fiber DAS” up to 6 watts.

QUATRA RED is best-in-class with 56 individually configurable channels on the Class A unit and 28 channels with 100Khz and 150kHz bandwidth options on the Class B variant (700MHz and 800MHz) and 1W downlink per Coverage Unit (CU) per band. Best-in-class channelized uplink squelch and micro-processor controlled automatic gain control (AGC) per time-slot, inherited from Nextivity’s carrier-grade LTE technology platform, unconditionally guarantees no interference to base stations and optimizes signal quality.

QUATRA RED includes all standard alarms, supports all NFPA and IFC-required monitoring, and connects to Nextivity’s carrier-grade, SOC 2 (Type 1)-certified WAVE portal, providing best-in-class on-demand remote monitoring, not just for standard alarms but also to ensure system KPIs.

Where competing products require integrators to purchase pieces and parts from a variety of vendors to create a complete solution, the QUATRA RED solution offers everything from the head end (Network Unit or NU), remotes (Coverage Unit or CU), Battery Back-up and Monitoring (MBBU), Remote Annunciator, Emergency Power-off Switch (EPO), and an As-Built Box. All NEMA 4X rated and optimized together.

No Noise Guarantee

By monitoring environmental changes and performing automatic adjustments, Cel-Fi QUATRA RED ensures emergency personnel stay connected in any situation by delivering industry-leading performance with a no noise guarantee.

Automatic Setting of Uplink Transmitted Power

QUATRA RED simplifies the optimization of uplink (UL) gain for emergency communication systems by eliminating the need for additional equipment or guessing the calculations. The system calculates path loss automatically, allowing for different values according to network requirements and the option to setup a target range.

Automatic Calculation and Setting of Isolation & Downlink Gain

While isolation is calculated in real-time and automatically set at 20 dB per NFPA 1221, the system allows for different values according to local ordinances. DL gain is automatically adjusted to achieve the required value.

Industry-First Talk-Out Guarantee

Cel-Fi ERCES solutions’ groundbreaking uplink (UL) test allows integrators to easily achieve industry-leading talk-out performance by measuring the signal traveling from the installation site to the remote tower via walkie-talkie. Using Cel-Fi COMPASS and the Cel-Fi WAVE PRO app, installers can test UL gain levels and view real-time analytics to ensure the best-possible signal-to-noise ratio.

Built-in Grid Test Functionality

With Cel-Fi WAVE PRO and Cel-Fi COMPASS, system integrators can test the downlink (DL) gain for the design planning stage and post-install performance evaluation. Export the Full Signal Report as a .csv, which includes key LMR/Operator Network parameters: Operator, RSSI, RSRP, RSRQ, Frequency, Band, PCI and more. Installers use system operation data to prepare for AHJ walk-through tests.

Built-in End-to-End Remote System Monitoring and Management

The web-based Cel-Fi WAVE Portal provides installers and authorized users remote monitoring, managing, and control of Cel-Fi ERCES systems from anywhere. In addition to easily adapting Cel-Fi systems to local fire codes, the WAVE Portal allows users to customize notification and policy parameters. The intuitive platform also offers advanced performance metrics on Cel-Fi solution’s individual components, including real-time high site-to-server antenna monitoring and donor signal quality reports.
