CEL-FI QUATRA

In-Building Cellular DAS for Large Spaces

Affordable Solutions that Rival the Performance of Legacy DAS

Built with Nextivity IntelliBoost® technology, the CEL-FI QUATRA family of cellular repeaters delivers industry-leading performance to large commercial buildings. These scalable, flexible systems are carrier approved, in-use across the globe on 200+ networks and offer proven fourth-generation chips that allow Nextivity to boost signals to the highest levels allowed. Our chips, designed and produced by Nextivity, put QUATRA CEL-FI boosters in their own repeater category featuring the lowest Total Cost of Ownership for large-scale deployments.

Scalable Solutions to 1M ft2

The ability of CEL-FI QUATRA systems to boost signals more than the competition allows us to cover more space with less hardware, driving overall costs down. While the coverage footprint for any system is dependent on the characteristics of the space (shape, open vs. walls, and type/density of furnishings), Nextivity QUATRA systems are designed to ensure everyone in the building has equally strong signals from all carriers.

Do More with DAS

Nextivity QUATRA family products are unique in the DAS, cellular repeater, and signal booster market – allowing customers to leverage their coverage solution to enable private networking and IoT sensor applications. The set of Nextivity products and services that allow enterprises to Do More with DAS are part of our family of WAVE Connected Technologies. This family includes Edge Services such as:

  • 5G Private Networking
  • IoT Sensor Networks
  • Panic Buttons
  • Smart Building Applications

These IoT/AI applications leverage the Nextivity cellular DAS infrastructure to add advanced sensing and other IoT capabilities with minimal investment and time-to-deployment. Nextivity DAS support various IoT technologies including Zigbee and BLE for quick deployment of off-the-shelf and proprietary sensing applications.

Flexible Signal Source – Off-Air or Small Cell

Most Nextivity DAS are deployed as off-air solutions, where the cellular signals being amplified, and distributed throughout the building come from a donor antennas mounted on the roof. With Nextivity QUATRA products, there is an option to deploy the systems in Supercell® Mode, where the QUATRA system is obtaining its signal from a small cell. In Supercell® Mode, the QUATRA® system manages the uniform distribution of the small signal throughout the site, creating a single robust enhanced signal source that covers the entire building. A QUATRA® in Supercell® Mode is more efficient than multiple small cells as it ensures coverage signals do not interfere with each other and that call drops due to handover are eliminated. Supercell® Mode is useful in densely populated buildings where additional capacity is needed, creating a scalable solution at a fraction of the cost of legacy DAS.

First Combined Public and Private Wireless Connectivity Solution

The CEL-FI QUATRA 4000c was the first cellular DAS to deliver advanced wireless connectivity, low-cost private networking, and IoT capabilities in a single system. It’s at the core of a flexible, scalable infrastructure designed to efficiently and effectively utilize existing network infrastructure to meet future challenges.
