The 2X HiBoost SLW Smart Link is a two-antenna system designed for large offices or building areas that need improved cell signal reception and have high user demands. The SLW Smart Link improves both voice and data to reduce dropped calls and missed emails and texts, keeping your business and employees connected with a stronger cell signal.

This kit includes two inside ultra-thin dome or regular dome antennas that send amplified signal to the phones in your building.

HiBoost LCD display and controls The HiBoost SLW amplifier features a backlit LCD display and controls for gain and power.

This system doubles your coverage!

The 2X HiBoost SLW system uses the same booster as the standard kit, but includes half‑inch carrier-grade coax cable with half the signal loss of the standard 400 coax. With two ceiling-mounted ultra-thin or dome antennas, this 2X system will double the coverage area provided by your system.

Double the coverage area The ultra-low loss coax cable and two antennas in this system double your amplified cell signal coverage area.

Who is the 2X HiBoost SLW Smart Link for?

  • Large offices and buildings with heavy cellular user and data loads.
  • Remote locations with weak cell service.
  • Urban locations with building materials that block outside cell signal (steel, glass, concrete, plaster, etc.).
  • Areas below ground level, and other places where cell reception is poor.

Monitor your SLW Smart Link system from your smartphone

HiBoost’s Signal Supervisor app for smartphones helps you set up and monitor your cell signal booster. The booster links to your iPhone or Android smartphone via a Bluetooth or WiFi connection. With Signal Supervisor, you can:

  • Register your booster via a QR Code or Bluetooth.
  • Monitor your signal booster’s status via Bluetooth.
  • Set up and receive remote alerts if your booster isn’t operating properly.
  • View your booster’s power settings, gain, and dBm output.
  • Manage multiple boosters.

HiBoost’s Signal Supervisor app is available for Apple iOSexternal link icon and Androidexternal link icon devices.

How the HiBoost SLW Smart Link works

The HiBoost SLW Smart Link amplifier receives the outside cell signal, amplifies it, and rebroadcasts it inside your office through two ceiling-mounted ultra-thin or dome antennas. This allows you to stay connected in areas where cell service is poor or where your office’s building materials interfere with signals from the local cell tower.

Works with all major cellular carriers

The HiBoost SLW Smart Link 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 indoor antenna should I choose?

This system gives you the choice of an indoor dome or panel antenna. Here are some general guidelines for selecting the right antennas.

  • The ceiling-mounted dome antenna works best in most circumstances. 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 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 2X HiBoost SLW Smart Link cover?

With strong outside cell signal (−95 dBm RSRP or greater), you can cover up to 65,000 square feet of indoor building space with 700 MHz signal. The size of the coverage area depends on many factors, including:

  • Outside cell signal strength received by the donor antenna.
  • The type of antennas you choose (dome or panel) and where you position them.
  • 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 LTE and 800 MHz signals travel farther than higher-frequency AWS and PCS 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.
