Active DAS hybrid extends award-winning technology to global markets, providing seamless multi-carrier coverage from a single system
Today at Mobile World Congress 2021 (MWC21), Nextivity Inc. announced the availability of the 3G/4G/5G multi-carrier Cel-Fi QUATRA 4000e in-building enterprise cellular coverage solution. The active DAS hybrid is designed and approved for use on all major carrier networks in Asia, Europe, the UK, and Oceania. The Cel-Fi QUATRA 4000e for enterprise buildings is a scalable solution that providers up to ~11,600 square metres (125,000 square feet), per Network Unit (NU).
Cel-Fi QUATRA 4000e is an all-digital solution built on award-winning Cel-Fi technology – Nextivity’s fourth generation Intelliboost chipset – and is the only product in its class on the market today that supports up to 100dB of gain. Each Cel-Fi QUATRA Network Unit (NU) can support up to six Coverage Units (CU) and features a built-in cellular modem for the Cel-Fi WAVE PRO Platform. Based on the award-winning Cel-Fi QUATRA 4000, it is also the first integrated product in the market to relay TDD (Time Division Duplex) LTE bands.
Unlike other products that offer a single boost value to only the strongest input signal, Cel-Fi QUATRA 4000e provides gain to each carrier signal independently, delivering maximum power levels across the board. That means subscribers across all networks can enjoy consistent, uninterrupted indoor cellular coverage in hospitals, schools, shopping malls, manufacturing facilities, office buildings, and other indoor settings instead of only those whose carrier has the strongest signal.
“Cel-Fi QUATRA 4000e gives mid-sized enterprises across a wide range of industries in Asia, Europe, the UK, and Oceania the flexibility to select from our single, dual, or multi-carrier solutions, depending on their specific requirements,” says Werner Sievers, CEO of Nextivity. “Cel-Fi QUATRA 4000e brings the full scope of coverage options to largely underserved markets while removing the cost, complexity, and time involved with traditional DAS solutions.”
Cel-Fi QUATRA 4000e can be ordered, delivered, installed, and operational in a matter of days or weeks, at a lower installed cost per square metre compared to more expensive DAS systems that typically require between 12 and 24 months for deployment from start to finish. Cel-Fi QUATRA achieves this by eliminating much of the complexity, and by leveraging RF-over-Ethernet (RFoE) and Power-over-Ethernet (PoE) technology. Cel-Fi QUATRA designs can also be expanded to high-rises and multi-building installations with fiber expansion options. Cel-Fi QUATRA uses a lossless digital method of signal distribution as opposed to the vast majority of DAS solutions that suffer from signal losses.
Cel-Fi QUATRA 4000e can also be deployed off-air or tethered to carriers’ small cells, or it can be integrated with carriers’ small cell equipment and operated in distributed small cell mode to create a multi-carrier Supercell™. A Supercell (i.e., a large single cell versus multiple independent small cells) provides uniform access to the capacity introduced by the small cell to improve cellular coverage in larger or densely populated areas. Supercells are inherently uncomplicated from a planning and deployment point of view and are far more resilient to the potential of interference or performance degradation considerations.
Cel-Fi QUATRA 4000e provides detailed and precise remote monitoring of both equipment and the specific wireless environment with Cel-Fi WAVE PRO, offering the quickest path to knowing the installation environment and passing acceptance testing. This substantially helps product support and enables downstream installation partners to easily implement service level agreements (SLAs) and recurring revenue models.
Cel-Fi QUATRA 4000e is available in multiple operator variations to accommodate the bands required for deployments in Asia, Europe, Africa, the Middle East, and Oceania. Integrators can purchase Cel-Fi QUATRA 4000 via Nextivity’s master distributors, while end customers can buy through Nextivity’s network of resellers. Cel-Fi QUATRA 4000e is regulatory-approved and meets strict license exemption rules in multiple countries including UK, Ireland and others.
