Large Scale Coverage Solution for Buildings.
Cel-Fi QUATRA 1000 is a scalable in-building cellular coverage solution that is both cost-efficient and easy-to-deploy, delivering high-quality signal in venues up to 50,000 square meters. It is a hybrid solution that combines the power of active DAS and Smart Booster technologies. It operates in off-air mode or can be integrated with the carrier’s small cell equipment and operated as a distributed small cell, creating a Supercell.
Depending on the environment, size, and space, the system utilises one or multiple Network Units (NUs), with each one providing power and distributing signal to up to four CUs. The system utilises Cat5e cabling for RF and Power over Ethernet, with no signal attenuation to the Coverage Unit (CU) embedded service antennas.
System Features
- MIMO RF inputs for (a) small cell donor or (b) external off-air donor antenna
- Network Unit (NU) (Head End) attaches to Coverage Unit (CU) (Remote Unit) via Cat 5e cable
- A single NU and up to four (4) CUs may be attached (hub and spoke architecture) in a Cel-Fi QUATRA system
- Multiple Cel-Fi QUATRA systems may be deployed to scale with building size
- Up to 100m (Cat5e) or 150m (23AWG CAT6/7) CU cable length
- Remote Management through Nextivity’s Cel-Fi WAVE cloud platform
- Easiest installation in its class
Wireless Features
- Supports up to four bands simultaneously from a single operator
- 3G/4G/5G support (WCDMA / HSPA+ / LTE)
- Supports FDD
- Peaceful coexistence with adjacent Wi-Fi (2.4 GHz & 5 GHz) and cellular devices
- Up to 100 dB system gain per band
