By Juan Pedro Tomás

Nextivity announced that its Cel-Fi QUATRA RED in-building public safety Emergency Responder Radio Communication System (ERRCS) solution is now available for partners in the US market.

Cel-Fi QUATRA RED delivers in-building coverage to Land Mobile Radio (LMR) systems and FirstNet-ready devices.

Nextivity said that the solution will be showcased via webinar on August 26 as part of the International Wireless Communications Expo (IWCE) virtual series.

“This has been a three-year journey for Nextivity,” said Werner Sievers, CEO of Nextivity. “Our goal was to use our disruptive technology platform to build the best communications solution for public safety professionals. With significant input from integrators and the public safety community, we applied our market-leading Cel-Fi technology that has changed the booster and DAS industry to improve and drive innovation in the public safety communications ecosystem.”

The company highlighted that the Cel-Fi QUATRA RED solution makes it easier for integrators to implement and quickly install communications solutions for the public safety market. QUATRA RED variants include Class A and Class B devices with 56 and 28 channels respectively, which can be shared between 700 or 800 MHz.

The solution also delivers an all-digital cellular signal that is up to 1,000 times stronger, using CAT 5e cabling for RF-over-Ethernet (RFoE) and Power-over-Ethernet (PoE), with no signal attenuation right to the perimeter of the building and without requiring a battery back-up unit with each remote unit. The new offering also features automated commissioning, isolation, and calibration of the uplink/downlink. The future-proof system includes FirstNet bands 2,4, 12, and 14 right out of the box.

Some key features of the new solution include:

– 1W to 6W

– Deployment options, with BDA or DAS configurations

– Class A with 56 fully-configurable channels

– Class B with 28 bandwidth selective channels

– 700/800 MHz for public safety with dedicated FirstNet Bands 14, 12, 4, and 2

– Automatic isolation measurement and set

– Automatic uplink / downlink calculation and set

– Talk-out guarantee that meets rigorous AHJ testing protocols

– Built-in real-time remote monitoring (wired and wireless)

– Microprocessor controlled AGC per time-slot to minimize near-far effect

– Uplink quelch

Key Cel-Fi QUATRA RED components include a network unit (NU), a coverage unit (CU) and a remote emergency power off switch (EPO).

Nextivity also noted that the QUATRA RED is UL 2524 compliant, NFPA / IFC compliant, and all components are NEMA4 rated.

The Cel-Fi QUATRA RED Class A product will be available to new partners nationwide at the end of September 2020 while the Class B product will be available at the end of November 2020
