Nextivity Cel-Fi Quatra - Enterprise Class Signal Booster

Cel-Fi QUATRA 3G / 4G Signal Booster for O2, EE, Three, Vodafone

Cel-Fi QUATRA 3G / 4G Signal Booster for O2, EE, Three, Vodafone
For Medium / Large Sites, Offices and Factories!!


Cel-Fi QUATRA is a scalable in-building cellular system for delivering high quality signal in venues up to 200,000 sq. ft. It is a cost-efficient and easy-to-deploy solution that combines the best of active DAS and Smart Booster technologies that have been widely adopted by carriers around the world, setting a new standard in Signal Boosting capabilities.

Provides 100dB of signal gain, 1,000 times stronger than traditional analogue boosters, which provide 60-70 dB of gain
Creates a bubble of coverage area up to 50,000 sq. ft. (4,700 sq.m.) per system, scaling up to 200,000 sq.ft. (18,600 sq.m.) by combining multiple systems together (See Sample Configurations below)
Boosts both 3G and 4G signal coverage for O2, EE, Three or Vodafone, and all hosted MVNO under the Network of your choice
Supports up to 4 bands simultaneously
Reduces the cell phones’ power requirements and extends their battery life
Remote Monitoring and Management via the WAVE Platform
Cel-Fi QUATRA is CE, FCC and ISED certified. Cel-Fi Signal boosters are legal to use and have been approved for use by mobile operators.

The basic QUATRA product bundle provided consists of one full system (25,000 to 50,000 sq.ft. coverage area) for the Off-Air configuration (explained below) and is the recommended solution for most venues. It includes one (1) Network Unit, two to four (2-4) Coverage Units (depending on the desired coverage area) and one (1) Indoor/Outdoor MIMO Antenna (Antenna Mount also included). Read the product details below for datasheets and additional information, or contact us for details.

Cel-Fi QUATRA 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 four CUs.

- Provides coverage in the Cel-Fi QUATRA system (up to four per Network Unit)
- Power delivered by Power-Over-Ethernet from the Network Unit
- Self-configuring and self-optimising

Cel-Fi QUATRA Off-Air Configuration

Cel-Fi QUATRA Off-Air Configuration

Cel-Fi QUATRA is comprised of a Network Unit (NU) and up to four distributed Coverage Units (CUs) dynamically networked into a single system. Cel-Fi QUATRA can be installed off-air (external antenna mode) to provide high-quality 3G & 4G mobile signal for voice & data, covering up to 50,000 sq. ft. Cel-Fi QUATRA will reduce dead zones and connectivity issues, expanding the network footprint with significantly higher system gain. It will also reduce the cell phones’ power requirements and extend their battery life. The QUATRA bundle offered here fits this type of configuration.

For larger venues, Cel-Fi QUATRA can be integrated with carrier small cell equipment and operated in distributed small cell mode, creating a Supercell. This configuration allows for up to four Systems to be linked together on the small cell, supporting a total of up to 4 Network Units / 16 Coverage Units. This scales the coverage area up to 200,000 sq. ft. (18,600 sq. metres). Please contact us for more details, if you are interested in this type of configuration.

Smart Cellular Coverage

Cel-Fi QUATRA is self-configuring and self-optimizing, distributes RF (Radio Frequencies) over Ethernet (RFoE), and leverages Power-over-Ethernet (POE) for ease and accuracy of installation (by Cel-Fi Certified professionals). The system is monitored and managed using the Cel-Fi WAVE Platform.

Configurations are available for use on global carrier networks.

Improves cellular reception for venues from 25,000 to 50,000 sq. ft. per system. Scalable to four systems for up to 200,000 sq. ft. (see “Sample Configuration” above)

Datasheets available on the relevant section on the right.

Finally, an Option for the Middleprise! - Optimized for Installers, Budgeted for Middleprise

Cel-Fi QUATRA is the first active DAS hybrid for spaces up to 50,000 sq. ft. (off air configuration) or 200,000 sq. ft. (small cell configuration). Cel-Fi provides solutions built specifically for customers in offices or industrial locations. Cel-Fi QUATRA distributes coverage with RF-over-Ethernet (RFoE) and power with Power-over-Ethernet (PoE), while finding the best signal with an 8-point antenna positioning solution; to ease installation at the distributed locations. Cel-Fi QUATRA can be deployed by Cel-Fi Certified professionals. Cel-Fi Certification is available at no cost through online training by Nextivity.

Cel-Fi QUATRA delivers a lower Total Cost of Ownership (TCO) over a Passive or Active DAS installation for a similar size venue. Cel-Fi Certified professionals can install and maintain the rich features of Cel-Fi QUATRA at the lowest CAPEX and OPEX of any in-building enterprise cellular coverage solution in the industry.

A Solution for the Carrier - Unconditionally Network Safe

Cel-Fi QUATRA is designed to improve indoor signal coverage without any risk of interference on the mobile network. Cel-Fi QUATRA provides a sophisticated network-safe solution that has been engineered to deliver multiple levels of network protection:

Uplink power control to prevent desensitizing the network
Echo cancellation and feedback control
Uplink gating
Signal qualification (channels are individually qualified, so noise or very poor signals won’t be amplified and degrade the network)
The Cel-Fi WAVE Platform cloud-based portal enables an operator to monitor signal KPI’s, such as channel configurations, RSRP, RSCP, SINR, and systems gains, providing control and optimization guidelines.
