Scales to Your Exact Building Size
Cel-Fi QUATRA EVO systems are custom designed by our experts to give you the coverage you need, without killing your budget.
No excess, no waste, no overrun. Just superior coverage to your specifications.
The Ultimate Provider of Reliable Cell Service
The Nextivity QUATRA EVO provides up to +100 dB of gain for up to two cellular networks. That’s hundreds of times more powerful than pure passive DAS systems.
With small cell or passive options, there’s no reason to ever deal with poor signal in your building again.
Carrier-Approved and Unconditionally Network Safe
Pre-approved for immediate deployment by Verizon, AT&T, T-Mobile, and more, the Cel-Fi QUATRA EVO by Nextivity is ready to go.
Don’t deal with poor signal for a minute longer than you have to.
Covers the Latest in Cellular Technologies
With 5G support, the QUATRA EVO is more future-proof than ever. Everything you would ever want from a cellular network for your business, the QUATRA EVO provides.
Remote Monitoring via the Nextivity WAVE Portal
Cel-Fi QUATRA systems are managed remotely using the cloud-based Nextivity WAVE Portal. The portal enables a number of features, including data modeling, alarms, notifications, and more.
Take control of your cellular network, and make it work for you with QUATRA EVO.
The Nextivity Cel-Fi QUATRA EVO is a next-generation distributed antenna system, providing 3G/4G/LTE/5G coverage for up to two cellular networks.
The Cel-Fi QUATRA EVO uses Nextivity’s 4th generation IntelliBoost chipset to provide up to 50% more coverage area than the older QUATRA 1000 and 2000 models. It is configurable for up to four bands across two separate carriers. The QUATRA EVO is pre-approved by all carriers and unconditionally network safe.
The QUATRA EVO is a hybrid cellular solution combining the best of active and passive DAS. Self-optimizing and self-configuring, its Nextivity WAVE Portal makes installation and configuration simple. It can be massively scaled using multiple Coverage Units to increase its coverage to up to 300,000 sq ft in strong outdoor signal conditions.
Nextivity’s QUATRA EVO cell phone signal booster is scalable, with up to 5 elements being used in designs:
- QUATRA EVO Network Unit: The hub of the system. Works with up to six coverage units, or can be used on its own to provide up to 75,000 sq ft of coverage.
- QUATRA EVO Coverage Unit: Attach up to six coverage units to a single network unit to scale up to 300,000 sq ft of coverage. Each Coverage Unit (CU) is powered by Power-over-Ethernet from the Network Unit.
- QUATRA EVO Small Cell Interface: Required for small cell installation. A small cell generates its own signal, freeing you from being reliant on existing outdoor signal in your area. The Nextivity Small Cell Interface simplifies RF connections between a small cell and a Network Unit.
- QUATRA EVO Range Extender: A power-over-ethernet (PoE) device which extends maximum distance between the Network Unit and Coverage Units. Extends cable lengths from ~100 meters (about 328.08 ft) to ~200 meters (about 656.17 ft).
- Passive Donor and Indoor Antennas: Attached via coaxial cable to collect and distribute the signal provided by the QUATRA system. These can be yagi or omnidirectional, panel or dome depending on your building’s layout and design. Each network or coverage unit can supply up to 16 indoor antennas.
The Cel-Fi QUATRA EVO is housed in cast metal, with an N-type Female RF interface for donor and server ports. Two category cables connect Network Units to Coverage Units for power and increased relay bandwidth. Each Coverage Unit supports a single whip antenna or multiple antennas in passive DAS.
Nextivity’s QUATRA EVO comes with a two-year warranty on any workmanship or material defects. Remote monitoring is available with Nextivity WAVE Portal Cloud management.
