Product Description

Features of the Nextivity CEL-FI QUATRA 4000c multi-carrier system

  • Designed for middleprise building facilities, with coverage of 10,000 to 200,000 square feet or more.
  • Uses dedicated runs of dual Cat 6/Cat 5e Ethernet cable, fitting easily into your existing I.T. infrastructure.
  • Improves 5G and 4G/LTE voice quality and data speed. (Learn more about 5G compatibility.)
  • Up to 100 dB max gain, up to 1,000 times stronger than most competing commercial cellular amplifiers.
  • Provides coverage for Verizon, AT&T, and T-Mobile simultaneously.
  • Monitor your cellular coverage with the online CEL-FI WAVE Portalexternal link icon with carrier-grade security. Monitor and manage devices, get performance metrics, receive email and text alerts if there are any interruptions in cellular service.
  • Certified by the FCC and preapproved by all major carriers. Unlike most active DAS systems, the CEL-FI QUATRA system does not require any licensing to install or operate in your building.
  • Industry-leading installation and lifetime support from Powerful Signal, the leader in improved in-building cellular signal.

The Nextivity CEL-FI QUATRA 4000c active DAS hybrid system is a multi-carrier solution that provides up to 100 dB of signal gain for each carrier network. The QUATRA 4000c improves cellular reception inside offices, warehouses, industrial facilities, campuses, and other buildings that have weak or no cell signal available.

How the Nextivity CEL-FI QUATRA 4000c works

  1. The QUATRA 4000c receives outside cellular signal from one to four rooftop-mounted antennas or an existing small cell interface.
  2. The received signal is sent to one or more Network Units (NUs) that amplify the signal gain and send the signal and power downline via two runs of Cat 6 or Cat 5e Ethernet cable.
  3. The two runs of Ethernet cables terminate at one to six Coverage Units (CUs) that amplify the signal again and distribute it to broadcast antennas via coax cable. (Plenum cable is available, if needed.)

A Network Unit can transmit amplified cell signal and power over Ethernet (PoE) up to 325 feet (100 meters) to the Coverage Unit(s). That distance can be doubled to 650 feet (200 meters) with an optional QUATRA Range Extender (QRE). This feature makes the CEL-FI QUATRA 4000c an excellent solution for large, long, and tall buildings.

The QUATRA 4000c is highly scalable: One NU can support up to six CUs, and, if the available signal from the roof antennas/small cell is strong enough, each CU can be split to six inside broadcast antennas. This means that one NU can support up to six CUs and thirty-six broadcast antennas. Because the QUATRA 4000c is so scalable, Powerful Signal can easily install additional NUs, CUs, and antennans in your building as your business grows.
