Cel-Fi QUATRA In-building Enterprise Cellular System
Hybrid active DAS for solving cellular coverage issues in the middleprise
Overview

The Cel-Fi QUATRA 1000, QUATRA 2000, and QUATRA 4000 systems leverage your existing Cat 6/Cat 5e infrastructure to provide an affordable, digital solution to in-building cellular reception problems in buildings from 10,000 to 200,000 square feet or larger.
The QUATRA system uses cellular signal from an off-air outdoor antenna or a carrier-specific broadband-connected small cell. One or more head-end Network Units (NUs) amplify the outside signal and transmit it through Ethernet cable to Coverage Units (CUs), which transmit the amplified signal to cellular phones and other devices.
- The QUATRA 1000 is carrier-specific, providing coverage for a single cellular network (Verizon, AT&T, T‑Mobile, or Sprint*).
- The QUATRA 2000 provides coverage for two carriers simultaneously (Verizon and AT&T or T‑Mobile and Sprint*). You may mix and match QUATRA 2000 Network Units to cover just the networks you need in your building.
- The QUATRA 4000 coves four networks simultaneously (Verizon, AT&T, T‑Mobile, and Sprint*).
Using your floor plans, Powerful Signal can design and install a Cel-Fi QUATRA system that will cover your office, warehouse, factory, public, or other mid-sized to large building for a fraction of the cost of a carrier-installed active DAS system. Contact Powerful Signal for more information!
Key features

- Provides enhanced voice and 4G/LTE/3G data.
- Industry leading coverage with up to 100 dB max gain, up to 1,000 times stronger than most competing commercial cellular amplifiers.
- Provides coverage for one, two, or four carriers, with a choice of Verizon, AT&T, T-Mobile, or Sprint* networks.
- Because it uses dedicated runs of Cat 6/Cat 5e Ethernet cable, the QUATRA system works within your existing I.T. infrastructure, with no coax cables to pull from the Network Unit to the Coverage Units.
- A Network Unit can transmit amplified cell signal and power (PoE) up to 325 feet (100 meters) to a Coverage Unit via Ethernet; an optional QUATRA Range Extender (QRE) can double that distance (650 feet or 200 meters). This makes the Cel-Fi QUATRA an excellent solution for large, long, and tall buildings.
- Highly scalable: One QUATRA 1000 or QUATRA 2000 NU can support up to four CUs, and a QUATRA 4000 NU can support up to six CUs. Powerful Signal can easily install additional Network and Coverage Units in your building as your business grows.
- The QUATRA 4000 supports more cellular frequencies than any other commercial cell signal amplifier, with out-of-the-box support for bands 26, 30, and 71 for better coverage on T-Mobile and Sprint* networks.
- Monitor your cellular coverage with the Cel-Fi WAVE online portal 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 special licenses to install or operate in your building.
- Industry-leading installation and lifetime support from Powerful Signal, the leader in improved in-building cellular signal.
*Although T-Mobile and Sprint became a single brand in 2020, many cell towers are still broadcasting Sprint signal and are supported by Cel-Fi QUATRA cellular amplifiers.
