About Cel-Fi QUATRA

The QUATRA Solution

The majority of cellular phone calls take place inside, but cell networks are outside. 80% of business users inside complain of poor coverage or dropped calls. A building’s materials, while improving energy efficiency, will block or inhibit cellular service from the outside network. To exacerbate the issue, cellular coverage is increasingly not optional. In fact, cellular coverage can be considered a safety or even regulatory requirement depending on the region. Building owners need a high-quality solution that can serve the middleprise and not take a year to deploy.

Integrators and Carriers have partnered with Nextivity to deliver a smart solution designed for middleprise buildings – Cel-Fi QUATRA solutions.

  • Cel-Fi provides the QUATRA BOM Estimator to help installers select the appropriate equipment in the right quantity, to eliminate the heavy cost / time of the planning effort.
  • Cel-Fi’s all-digital, scalable, PoE category cable solution makes it ideal for Single or Multi-Carrier environments.
  • Cel-Fi created a new solution category that combines its core technology with the architecture of an Active DAS – to deliver an Active DAS Hybrid – built for Installers.

Speed of Installation, higher quality in-building cellular solutions, and cost savings – are some of the reasons building owners, facility managers, and IT professionals are making the smart investment in the Cel-Fi QUATRA solution.

A Solution for the Carrier

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 muting, when handsets (UE) are not detected
  • 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 equipment and network KPI’s, such as channel configurations, RSRP, RSCP, SINR, and systems gains, providing control and optimization insight.

Smart Cellular Coverage

Cel-Fi QUATRA is an active DAS hybrid solution for delivering high quality in-building cellar coverage in middleprise venues. It combines the best of active DAS and the Cel-Fi technologies that have been widely adopted by carriers around the world. It operates in off-air mode or can be integrated with carrier small cell equipment and operated in distributed small cell mode, creating a Supercell. Cel-Fi QUATRA can be configured with components, for single or multi-carrier environments.

  • Highest Coverage Gain: With 1000x more gain than the competition, Cel-Fi QUATRA delivers a stronger signal and provides a larger coverage footprint in environments where the incoming signal is weak. This ensures the strongest possible signal is sent to the inside antennas.
  • Highest Downlink Power: With 4x more downlink power than the competition, QUATRA ensures the strongest signal is sent to inside antennas to provide the largest coverage footprint.
  • Highest Uplink Power: 2x more uplink power than the competition allows for a stronger signal transmission to the tower to maximize user capacity and increase the range from the cell site.
  • Multi-Carrier 3G / 4G / 5G Voice and Data: Cel-Fi is the only cellular coverage solution available with up to 100 dB off-air gain and single or multi-carrier support for 3G, 4G, and 5G for Voice and Data. Each Carrier has dedicated maximized gain enhancement; no sharing limited bandwidth between carriers.
  • Supercell Mode: QUATRA systems can be connected to a single small cell, or multiple small cells, to form a coordinated Supercell. Supercells provide uniform access to the capacity introduced by the small cell, and are preferred by carriers in densely populated and high traffic areas.
  • Scalable PoE Solution: Use existing dedicated Category Cable lines, or simply drop new ones without permits or difficult trenching. A scalable easy to deploy, all digital solution that also delivers power from NU to CU.
  • Built for Installers: Cel-Fi QUATRA ships with installer tools that simplify the planning process, equipment selection, and antenna aiming to automate the hard math calculations of RF Planning and eliminate the complexity of specifying the system for the unique venue requirements.
  • Setup, Maintenance, and Remote Management: Cel-Fi provides the WAVE Portal application for easy setup, provisioning, and management via a Smart Phone or Cloud Portal, providing quick access to install and help your customers faster.
  • Network Safe and Carrier Approved: Cel-Fi products are built on an advanced Intelliboost technology to deliver the strongest possible signal when and where needed. As the environment changes, Cel-Fi changes with it, without shutdown or interruption. Cel-Fi has partnered with carriers around the world to distribute their signal at the safest and highest levels, guaranteeing consistent coverage.
  • Fiber Expandable: Use fiber lines to expand coverage to a secondary facility up to 2.0 km from the NU.

Scalable Solutions

Cel-Fi QUATRA is a scalable solution that utilizes one or multiple Network Units, depending on the environment and size of the space, with up to four distributed Coverage Units connected to each Network Unit.

Off Air Mode

Cel-Fi QUATRA can be installed off-air, using either a MIMO panel or omni donor antenna to provide high-quality in‑building wireless connectivity. Cel-Fi QUATRA can be deployed by installers or IT personnel with Cat5e skills (no RF engineering skills needed).

Supercell Mode

A Supercell is comprised of a Cel-Fi QUATRA system connected to a small cell. Multiple Cel‑Fi QUATRA systems can be connected to a single small cell, or multiple small cells, to form a coordinated Supercell. A Supercell with Cel-Fi QUATRA is more efficient than multiple small cells, and the CUs of a Cel-Fi QUATRA system connected to a Supercell do not interfere with one another.

Fiber Extension

Expanding the capabilities of Cel-Fi QUATRA systems, the Cel-Fi QUATRA Fiber Range Extender (QFRE) increases the distance between the Network Unit and Coverage Unit up to 2.0 km (1.24 miles). QUATRA 4000 systems are also compatible with the Cel-Fi QUATRA 4000 Fiber Hub, which offers the same distance flexibility as the QFRE and allows a single NU to support up to 12 CUs. These solutions are ideal for high-rise structures, long distances, or multi-building facilities.

Remote Monitoring and Management

The Cel-Fi WAVE Portal is a web-based platform that provides installers and authorized users remote monitoring, managing, and control of Cel-Fi installations. Compatible with all Internet-connected Cel-Fi systems, the WAVE Portal offers carrier-grade security and is accessible from any web browser. By logging into the platform from a computer or mobile device, users can organize all their deployments, commission new Cel-Fi QUATRA systems, view real-time system performance, adjust alarm policies and notification settings, update software, and much more.

Cel-Fi QUATRA was built with the integrator and installer in mind. Setup begins with planning, with installers using the Cel-Fi QUATRA BOM Estimator tool to capture basic environmental information. This then returns a list of equipment needed.

While IBWave is not needed for design, a variety of templates are available for download to accelerate the design phase. Cel-Fi QUATRA is an all-digital solution designed to eliminate the coax-related problem of signal attenuation over distance, and intelligently manage gain. During installation, Cel-Fi AntennaBoost technology makes antenna mounting and pointing much easier, so that the process can be completed in minutes. The solution incorporates cloud-based software (WAVE) and an app for commissioning and maintenance, enabling installers to offer a variety of SLAs to customers.
