    Product Description

    Nextivity Cel-Fi QUATRA 4000i (Part 90) is in-building enterprise cellular and public safety signal booster system that improves coverage of all four major carrier networks in USA including bands 2, 4, 5, 12, 13, 25, 26, 30, 41, 71. It is a hybrid active DAS that solves coverage issues for voice and data.

    This hybrid signal amplifier or small cell signal enhancing system is easy-to-deploy and cost-efficient. This hybrid solution combines the best of Smart Booster and digital active DAS technologies. It is self-optimizing and self-configuring, while installation and configuration is made simple by the Cel-Fi WAVE Portal.

    Cel-Fi WAVE Platform cloud-based remote management platform enables device maintenance and management. Key features of the WAVE platform include:

    • Cel-Fi device and asset management.
    • Mobile and desktop applications.
    • Data modelling and reporting.
    • Alerts and alarms can be customized.
    • Globally trusted carrier-grade security.
    • The WAVE Platform portal can be accessed through its own dashboard, or integrated via APIs.

    The QUATRA is scalable and can be used to cover up to 500,000 square feet. It either operates in off-air mode, or it can be integrated with small cell equipment. In the latter case, it operates in distributed small cell mode and creates a Super Cell.

    Active DAS Hybrid.

    Cel-Fi QUATRA 4000i is available in two versions both offering all 4 major carrier coverage simultaneously.

    Its outdoor cellular donor signal is provided by the wide-band antennas. Coverage is provided via Power over Ethernet (PoE), eliminating the need for separate power supplies for the Coverage Units. The Network Unit uses Dynamic gain control in to automatically ensure the best coverage and maximum gain at all times.

    System Components:

    Network Unit (NU).

    The hub of the system is the QUATRA Network Unit (NU).  Its scalable design can work with between 1 and 6 Coverage Units (CU) to cover up to 75,000 square feet. The NU provides the donor signal to system and supplies power to up to 6 CUs (Coverage Units). It can be managed by the WAVE Platform. Model # Q44-1234CNU.

    Coverage Unit (CU).

    The remote radio head of the system that rebroadcasts the donor signal is called the Coverage Unit (CU). Each CU provides coverage in the QUATRA system, with up to 6 per NU. Each CU is powered from the NU by Power-Over-Ethernet (POE). Model # Q41-5ECU.

    Donor Antenna.

    The Wideband Antennas include the Cel-Fi LPDA-R Outdoor Antenna (model # A62-V44-200), Blade Antenna (model # A21-V44-500), LP SISO Indoor Low Profile Omni Antenna (model # A11-H43-201).

    Range Extender (QRE).

    The Range Extender is a Power over Ethernet (PoE) device that extends the maximum distance between the NU and a CU. Each range extender permits additional cable lengths.

    Carrier and Bands Configurations Available:

    AT&T Configurations.

    Bands: 12 and 5, 12 and 25, 12 and 4, 12 and 2, 30 and 5, 30 and 25, 30 and 4, 30 and 2.

    Note: For any signal booster to help, outside signal strength must be -110 dB or better. Please check outside signal level in decibels before ordering. If it is too weak, submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.
