Who is the SureCall Fusion5s for?

  • Large 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 4G internet at home or in the office.

One-antenna kit

A Fusion5s system with one inside antenna will cover most large homes and small offices as long as there is adequate outside cell signal.

This kit includes the standard components, above, plus:

Top Signal dome antenna TS250374 icon Choice of… Wideband indoor dome antenna TS250374
Top Signal 4G Compact Indoor Panel Antenna N-Female TS260782 icon …or

Two-antenna kit

A Fusion5s system with two inside antennas is a good solution if you have two specific problem areas in your home or office. Because there is some loss in splitting the signal two ways, we recommend this solution only if you have strong outside cell signal.

This kit includes the standard kit components, above, plus:

Top Signal dome antenna TS250374 icon Choice of… Wideband indoor dome antenna TS250374 (×2)

How the SureCall Fusion5s 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 major wireless carriers:

  • U.S. carriers, including Verizon, AT&T, T‑Mobile, Sprint, U.S. Cellular, and most others.
  • Canadian carriers, including Rogers, Bell Canada, Telus, Wind, 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 antennas should I choose?

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

Outside (donor) 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.

Inside (broadcast) antenna:

  • A ceiling-mounted dome antenna works best in most circumstances. It broadcasts downward in a spherical shape (similar to the shape of a light bulb) and usually gives significantly more coverage than a panel antenna. A dome is also less noticeable than a wall-mounted panel. The dome antenna does, however, require access above the ceiling to pull cable and attach it to the antenna.
  • A wall-mounted panel antenna works best if you don’t have access above your ceiling or if you need to mount the broadcast antenna on the outside perimeter of the area you want to cover. The panel antenna broadcasts forward in a wedge shape (similar to beam from a flashlight).

If you’re still not certain which antennas will work best for you, please call us at 866‑912‑3444. 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 cover?

This system comes with one dome antenna that broadcasts improved cellular signal in a spherical pattern or a panel antenna that broadcasts in a horizontal cone shape. With strong outside cell signal (−95 dBm RSRP or greater), one antenna can cover up to 6,000 square feet of indoor building space with 700 MHz signal and two antennas can cover up to 12,000 square feet. The size of the coverage area depends on many factors, including:

  • Outside cell signal strength received by the donor antenna.
  • Which indoor broadcast antenna your choose. A dome antenna typically provides better signal coverage than a panel antenna.
  • 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.
