About QUATRA 4000/4000i

CEL-FI QUATRA 4000 is an affordable, all-digital active DAS hybrid solution that provides uniform, high-quality cellular signal throughout any building. Solving spotty cellular coverage, poor voice quality, dropped calls, and dead zones in middleprise and enterprise buildings, the system delivers industry-leading signal gain up to 100 dB that ensures reliable cellular connectivity.
Unlike older analog boosters and passive DAS technology, QUATRA 4000 utilizes category cable for RF and Power over Ethernet, with no signal attenuation right to the perimeter of the building. In addition to being the most powerful solution on the market, the system is cost-effective, designed to be installed within days (compared to months typical of other solutions), carrier approved, and guaranteed network safe.
Up to 100 dB Max Gain for 3G, 4G, and 5G Voice and Data
All Digital, Category Cable PoE/RFoE Solution
Scalable Up to 125,000 ft2 Coverage per Network Unit
Off-Air or SuperCell Mode with Fiber Expansion
Network Safe and Carrier Approved with No Noise Guarantee
Remote Monitoring and Management via WAVE Platform

System Components

QUATRA 4000 Network Unit (NU)

The Network Unit (NU) is the hub of the system. The scalable design works with one to six Coverage Units to provide up to 125,000 ft2 (11,600 m2) of coverage.
  • Relays donor signal throughout system
  • Provides power to Coverage Units (up to six)
  • Connects via Ethernet or LTE Modem to the CEL-FI WAVE Platform for remote monitoring and management
