Features of the SureCall Fusion5X 2.0

  • Maximum gain for offices up to 20,000 square feet.*
  • Auto adjusting gain with SureIQ™ Technology prevents booster shutdown in strong signal situations.
  • Sturdy metal case with heat sink.
  • Choice of outside antennas at no additional charge. (Get help picking the right antennas.)
  • Includes 400 coax cable and commercial-grade antennas and components.
  • Carrier agnostic: Works with all major U.S. and Canadian carriers.
  • Improves 5G, 4G LTE, and 3G service for voice, text, and data. (Learn more about 5G compatibility.)

The SureCall Fusion5X 2.0 is designed for small and medium-sized offices that need improved cell signal reception throughout the building. The Fusion5X improves both voice and data to reduce dropped calls and missed emails and texts, keeping your employees, clients, and customers connected with a stronger cell signal.

This system includes an inside flat dome antenna that sends amplified signal to the phones in your office.

* 20,000 square feet of indoor coverage is possible with strong outside cell signal. Weaker outside signal and/or fewer antennas will result in less indoor coverage. (See below.)

SureCall Fusion5X 2.0 front panel The SureCall Fusion5X 2.0 features automatic gain control—no manual tuning or adjustments are needed to get the strongest possible signal in your office.

Who is the SureCall Fusion5X 2.0 for?

  • Offices in urban environments with building materials that block outside cell signal (steel, glass, concrete, plaster, etc.).
  • Offices in remote locations with weak cell service.
  • Basements and other below-ground rooms where cell reception is poor.
  • Offices that frequently experience dropped calls, undelivered texts, or slow 4G internet service.

Optional plenum air coax cable upgrade

The SureCall Fusion5X 2.0 system includes 400-type coax cable to connect the amplifier to the inside antennas. If your building requires fire-rated cable in plenum spaces, please ask us about upgrading to half‑inch plenum air coax. Plenum cable fully meets state and federal building codes.

Plenum cable also has nearly half the signal loss per foot of cable compared to 400-type coax cable, delivering stronger signal from the SureCall amplifier to your phones and other cellular devices.

Call Powerful Signal at 435-634-6800 for more information.

400-type coax cable and plenum air coax cable terminated with N-male connectors Upgrade your SureCall Fusion5X 2.0 system from standard 400 coax cable (left) to fire-rated ½″ plenum air cable (right) for fire code compliance and better performance.

How the SureCall Fusion5X 2.0 works

Using SureCall’s patented SureIQ™ technology, the Fusion5X 2.0 receives the outside cell signal, amplifies it, and rebroadcasts it inside your office through one or more ceiling-mounted thin dome antennas. This allows you to stay connected in areas where cell service is poor or where your building’s construction materials interfere with signals from the local cell tower.

Works with all major cellular carriers

The SureCall Fusion5X 2.0 works with all major wireless carriers, including Verizon, AT&T, T-Mobile, Sprint, UScellular, and most others.

It operates on common 4G/3G cellular frequencies.

  • 700 MHz (SMH) bands 12, 13, 17.
  • 850 MHz (Cellular 850) band 5.
  • 1700/2100 MHz (AWS) band 4.
  • 1900 MHz (PCS) bands 2, 25.

Which antenna should I choose?

This kit gives you the choice of an outdoor directional or omnidirectional antenna. Here are some general guidelines for selecting the right antenna.

  • A cylinder omnidirectional antenna works best in most circumstances. The omni gathers signal from all carrier towers in all directions.
  • A wedge-shaped LPDA directional antenna works best if your building is in a remote location with one single, distant tower providing cell service for your area. The LPDA is also an excellent choice if there’s a powerful cell tower nearby but you need to bypass that tower in favor of a more distant one operated by your preferred carrier.

If you’re still not certain which antenna will work best for you, please call us at 435-634-6800. Our technical support representatives will be happy to discuss your specific requirements and give you a recommendation based on years of professional experience.

How much area will the SureCall Fusion5X 2.0 cover?

This system comes with a thin dome antenna that broadcasts improved cellular signal in a spherical pattern. With strong outside cell signal (−95 dBm RSRP or greater), this antenna can cover up to 20,000 square feet of indoor building space with 700 MHz signal. The size of the coverage area you’ll experience depends on many factors, including:

  • Outside cell signal strength received by the donor antenna.
  • Which outdoor donor antenna your choose. The omnidirectional antenna is easier to set up and will pick up signal from all towers and carriers in a 360° radius. The directional (LPDA) antenna provides stronger signal gain by targeting a specific tower, possibly with access to fewer carriers.
  • Inside building materials. Cellular frequencies pass through wood framing and drywall more easily than through steel and concrete.
  • Cellular frequencies used by the carrier and the device. Lower-frequency 700 MHz and Cellular (850 MHz) signals travel farther than higher-frequency PCS (1900 MHz) and AWS (1700/2100 MHz) signals.

Substandard or inadequate conditions in any of these factors will reduce your coverage area.

Powerful Signal has over a decade of experience designing and installing cellular amplification systems. Please call us at 435-634-6800 or contact us online and we’ll be happy to calculate the coverage area this system will provide in your building and answer any other questions about this amplifier.
