The SureCall Fusion5s 2.0 is designed for small to midsized homes and small offices that need improved cell signal reception throughout the building. The Fusion5s improves both voice and data to reduce dropped calls and missed emails and texts, keeping your family members, friends, employees, and customers connected with a stronger cell signal.

SureCall Fusion5s 2.0 gain controls The SureCall Fusion5s 2.0 features optional manual gain controls for fine tuning signal strength based on your building’s needs.

Who is the SureCall Fusion5s 2.0 for?

  • Small to midsized homes and small offices in remote locations with weak cell service.
  • Small offices in urban environments with building materials that block outside cell signal (steel, glass, concrete, plaster, etc.).
  • Basements and other below-ground rooms where cell reception is poor.
  • Those who frequently experience dropped calls, undelivered texts, or slow cellular data at home or in the office.

How the SureCall Fusion5s 2.0 works

Using SureCall’s patented SureIQ™ technology, the Fusion5s receives the outside cell signal, amplifies it, and rebroadcasts it inside your home through a ceiling-mounted dome antenna or wall-mounted panel antenna. This allows you to stay connected in areas where cell service is poor or where your home’s construction materials interfere with signals from the local cell tower.

Works with all major cellular carriers

The SureCall Fusion5s works with all works with all major wireless carriers, including Verizon, AT&T, T-Mobile, DISH Wireless, UScellular, GCI Alaska, and most others.

It operates on common 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 antennas should I choose?

This system gives you the choice of an outdoor directional or omnidirectional antenna and one or two indoor dome or panel antennas. Here are some general guidelines for choosing the right antennas.

Outside (donor) antenna:

  • The cylindrical Top Signal omnidirectional antenna works well in most situations. An omni antenna gathers signal from all carrier towers in all directions, and it’s also easier to set up.
  • The wedge-shaped SureCall directional antenna (LPDA) works best if your home has a reasonably clear line of sight to a specific cell tower that provides service for your cellular network. The directional antenna is also an excellent choice if another carrier has a powerful cell tower nearby, but you need to bypass that tower in favor of a more distant one operated by your preferred carrier. A directional antenna needs to be tuned, so its setup is more involved than setting up an omni antenna.

Inside (broadcast) antenna:

  • The ceiling-mounted Top Signal EDGE dome antenna works best in most situations. It broadcasts downward and all around in a shape similar to a donut or an inner tube. It usually gives more broad, even coverage than a wall-mounted panel antenna and is less noticeable than a panel antenna. Installing a dome antenna does, however, require that you have access above the ceiling to pull cable and mount the antenna.
  • The wall-mounted Top Signal EDGE panel antenna broadcasts forward in a sideways teardrop shape. It’s a better option if you don’t have access above your ceiling or if you want to mount the antenna on the outside perimeter of the area you want to cover. It’s also a good option for long, narrow indoor areas.

If you’re still not certain which antennas 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 Fusion5s 2.0 cover?

This system comes with one or two inside antennas. With strong outside cell signal (−95 dBm RSRP or greater), it can cover up to 7,500 square feet of indoor building space with 700 MHz signal. Two inside antennas will divide that signal for more even distribution throughout a long, narrow building.

The size of the coverage area 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).

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

Powerful Signal has has been designing and installing cellular amplification systems since 2007. 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.
