Introduction to QUATRA 4000
Understanding Cellular Coverage
Spotty cellular coverage, poor voice quality, dropped calls, and dead zones continue to plague occupants in
buildings of all shapes and sizes. Cel-Fi QUATRA solves that problem. It is an affordable, all-digital solution,
providing uniform, high quality cellular signal throughout a building. Cel-Fi QUATRA is scalable to fit buildings of
all sizes, and is carrier approved and guaranteed network safe.
Unlike traditional analog boosters and passive DAS technology, Cel-Fi QUATRA delivers a cellular signal that is up
to 1000x stronger, utilizing CAT 5e (or better) cabling for the connection between the head end and each remote.
The remotes are powered via Power over Ethernet (PoE), delivering an un-attenuated signal throughout the building.
Cel-Fi QUATRA can be installed in just days (compared to months typical of other solutions), and at a price point
that meets the middleprise budget.
The Cel-Fi QUATRA Solution
While cellular networks are outside, the majority of calls take place inside. A recent study showed 80% of business
users inside complain of poor coverage or dropped calls. Modern building materials, while improving energy
efficiency, will block or inhibit cellular service from the outside network. To exacerbate the issue, cellular coverage
is increasingly critical. In fact, cellular coverage can be considered a safety or even regulatory requirement,
depending on the region. Building owners need a flexible, high-quality solution. Installers and Value-Added
Resellers need a product that can serve the majority of building types and not take months to deploy.
 Cel-Fi created a new solution category that combines its core technology with the architecture of an Active
DAS – to deliver an Active DAS Hybrid – carrier-grade but built for Installers.
