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.

CEL-FI QUATRA: 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 4G and 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.
