System Components

QUATRA 4000c Network Unit (NU)

The Network Unit (NU) is the hub of the system and features four donor ports: three operator-specific ports and one for a private networking signal source. The scalable design works with one to six Coverage Units to deliver public and private cellular coverage inside enterprise facilities.

  • 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

QUATRA 4000c Coverage Unit (CU)

The Coverage Unit (CU) is the remote unit of the system that rebroadcasts the donor signal. The cost efficient and easy-to-deploy system leverages Power over Ethernet (PoE) for up to six CUs.

  • Provides coverage throughout facility (up to six per Network Unit)
  • Power delivered by Power over Ethernet from the Network Unit
  • Self-configuring and self-optimizing
  • Only compatible with CEL-FI QUATRA 4000c NU

Model Number:
_ › Q41-RECU

QUATRA 4000 Fiber Hub

The CEL-FI QUATRA 4000 Fiber Hub expands the Network Unit capacity from six to up to twelve Coverage Units. The Fiber Hub can be installed 2.0 km (1.24 M) away from the NU to cover large spaces while maintaining the same signal quality throughout the system.

  • Donor source over fiber
  • FCC certified
  • SFP+ module not included​
