Cel-Fi QUATRA | 4G/LTE Signal Booster

Cel-Fi QUATRA is an active DAS hybrid solution for delivering high quality in-building cellular coverage in medium to large sized buildings. Cel-Fi QUATRA can be configured to boost the signal for buildings ranging in size from 25,000 square feet up to 250,000 square feet and it can boost the signal from multi carriers, not just one.

Why Choose Quatra verus older analog boosters? Unlike older analog boosters and passive DAS technology, Cel-Fi QUATRA delivers a cellular signal that is up to 1000x stronger, utilizing existing CAT5e cabling for RF and Power over Ethernet, with no signal attenuation right to the perimeter of the building.

Cel-Fi QUATRA can be installed in just days and at a reasonable cost.

How It Works

Cel-Fi QUATRA is a Scalable Solution

Cel-Fi QUATRA is a scalable solution that utilizes one or multiple Network Units (NU) depending on the environment and size of the space, with up to four distributed Coverage Units connected to each Network Unit.

Off Air Mode

Cel-Fi QUATRA can be installed off-air, using either a MIMO panel or omni donor antenna to provide high-quality in‑building wireless connectivity. Cel-Fi QUATRA can be deployed by installers or IT personnel with Cat5e skills (no RF engineering skills needed).

Supercell Mode

A Supercell is comprised of a Cel-Fi QUATRA system connected to a small cell. Multiple Cel‑Fi QUATRA systems can be connected to a single small cell, or multiple small cells, to form a coordinated Supercell. A Supercell with Cel-Fi QUATRA is more efficient than multiple small cells, and the CUs of a Cel-Fi QUATRA system connected to a Supercell do not interfere with one another.
