CEL-FI QUATRA EVO Dual-Network Signal Boosters for Enterprises & Large Areas

CEL-FI QUATRA EVO Dual-Network Signal Boosters for Enterprises & Large Areas

Get a QUATRA EVO System Design & Quote

CEL-FI QUATRA EVO is a professionally designed Active DAS solution for commercial buildings that need reliable indoor coverage from one or two mobile network operators.

It can be configured for a single operator or for two operators and uses distributed Coverage Units to deliver cellular coverage throughout the required areas of the building.

The correct system design depends on the operator signals available, building layout, target coverage areas, cable routes and number of Coverage Units required, so QUATRA EVO is specified for the individual site rather than sold as a fixed online bundle.

Tell us about the building and the networks you need to improve. Frequency Signal Solutions will assess whether QUATRA EVO is the right solution and provide an indicative proposal, with a site survey arranged where required.

Improve Coverage for One or Two UK Mobile Networks

CEL-FI QUATRA EVO can be configured for one or two UK host mobile networks. In single-operator mode, the system is dedicated to one operator; in dual-operator mode, it can distribute coverage for two operators through the same Active DAS architecture.

 

Customers using compatible mobile providers hosted on the selected networks can also benefit from the improved host-network coverage.

 

For projects requiring three networks in a smaller commercial environment, G43 may be appropriate. For larger or more complex projects requiring more than two host networks, QUATRA 4000e should be considered.

Remote Monitoring & Management

QUATRA EVO connects to the Nextivity WAVE Platform for remote monitoring and management. This provides authorised support teams with visibility of system status, configuration and performance after installation.

 

Frequency Signal Solutions can provide ongoing monitoring and technical support as part of the project where required.

Where QUATRA EVO Fits

QUATRA EVO is designed for commercial environments that require scalable indoor coverage from one or two mobile networks. Typical applications include offices, hotels, healthcare facilities, schools, retail sites, warehouses and other larger or more complex buildings where a distributed Active DAS architecture is more appropriate than a single booster installation.

 

A Network Unit can support up to six Coverage Units using category cabling and Power over Ethernet. Optional fiber expansion can provide additional design flexibility for larger, distributed or multi-building environments.

 

Suitability is determined by the networks required, donor signal, building construction, layout and target coverage areas rather than by building size alone.

Check Whether QUATRA EVO Is Suitable
Ofcom Legally Compliant

CEL-FI QUATRA systems can be deployed in the UK under Ofcom's licence-exemption requirements when the system is correctly specified, configured and installed in accordance with the applicable requirements.

 

For more information about UK mobile repeater rules and IR2102, read our guide to legal and Ofcom-compliant mobile signal boosters.

Survey, Design, Installation & Support

Frequency Signal Solutions can manage the complete QUATRA EVO project from initial assessment through to system design, professional installation, commissioning, testing and ongoing support.

 

The design can include donor antenna planning, Network Unit and Coverage Unit locations, structured cabling routes, fiber expansion and the mobile networks that need to be supported.

 

The objective is to design the appropriate in-building coverage system for the site rather than simply supply QUATRA hardware.

Discuss Your QUATRA EVO Project
Not Sure Whether QUATRA EVO Is Right for Your Building?

Tell us which mobile networks need improving, the type and approximate size of the building, the areas requiring coverage and what mobile signal is currently available outside. We’ll advise whether G41, G43, QUATRA EVO or QUATRA 4000e is the appropriate CEL-FI solution.

CEL-FI QUATRA EVO is a distributed antenna system (DAS) hybrid solution that combines the strength of passive and active DAS technologies to deliver high-quality mobile signal in buildings of up to 200,000 ft2 / 19,000 m2 in size. CEL-FI QUATRA EVO delivers a mobile signal that is up to 1000x stronger than analogue, utilising CAT 5e cabling for RF and power over ethernet, with no signal attenuation right to the perimeter of the building.
With different configuration options, quick to install timelines and simplicity in IT maintenance, it has put enterprise-class mobile signal boosting within reach of many businesses at a price that is aligned with their budget.How QUATRA EVO WorksQUATRA EVO is an all-digital Active DAS system. In an off-air installation, donor antenna signals are fed into the Network Unit, which processes the selected operator signals and distributes them over category cabling to Coverage Units positioned throughout the building.
The Network Unit can support up to six Coverage Units and provides both RF distribution and power over the category-cable infrastructure. Optional fiber expansion can be used where the design requires additional Coverage Units or greater distance between system components.
QUATRA EVO can be configured for either one operator or two operators depending on the coverage requirement.

What is Included?CEL-FI QUATRA EVO is a scalable solution that utilises one or multiple Network Units, depending on the environment and size of the space, with up to six distributed Coverage Units connected to each Network Unit.Network UnitThe Network Unit (NU) is the hub of the system. The scalable design works with one to six Coverage Units to provide up to 125,000 ft2 (11,600 m2) of coverage, per Network Unit.
  • Provides donor signal to the CEL-FI QUATRA EVO system
  • Provides power to Coverage Units (up to six)
  • Connects via ethernet or LTE Modem to the CEL-FI WAVE Platform for remote monitoring and management
Coverage UnitThe Coverage Unit (CU) is the remote unit of the system that rebroadcasts the donor signal. The cost efficient and easy-to-deploy system leverages Power-Over-Ethernet (POE) for up to six CUs from each NU.
  • Provides coverage in the CEL-FI QUATRA system (up to six per NU)
  • Power delivered by Power-Over-Ethernet from the NU
