Product Description

Features of the Cel‑Fi DUO+ Wireless Smart Signal Booster®

  • Our most powerful cell phone signal booster for homes.
  • Two wireless units for fast, easy setup without cables or antennas.
  • Monitor and configure the boosters with the Cel‑Fi WAVE app for smartphones and desktop computers.
  • Boosts 4G LTE voice and data for Verizon smartphones and cellular devices. (See the list of supported frequencies, below.)
  • Boosts cell signal for multiple users.

The Cel‑Fi DUO+ improves HD voice and data coverage for Verizon 4G LTE/XLTE/VoLTE. With up to 100dB of gain, the DUO+ improves cellular service by eliminating dead zones, dropped calls, and slow data inside your home.

The DUO+ is fully self-contained and self-configuring. It requires no external antennas or cables—simply plug in the Network Unit and Coverage Unit and enjoy better signal within minutes.

Who is the Cel‑Fi DUO+ Wireless Smart Signal Booster for?

  • Individuals and families who are Verizon customers.
  • Those who want the easiest setup experience, without installing antennas and cables.
  • Situations where installing a rooftop antenna isn’t possible, including large apartments and condominiums and homes with HOA restrictions.
  • Those who frequently experience dropped calls, undelivered texts, or slow 4G internet at home.
  • Homes in remote locations with weak cell service (new communities, rural areas, cabins, etc.)
  • Homes with building materials that block outside cell signal (plaster, concrete, UV-coated windows, etc.).

Do-it-yourself installation

You can set up the Cel‑Fi DUO+ Wireless Smart Signal Booster system in only a few minutes. (See Documentation, below, to download the quick start guide with detailed installation instructions. The video at the bottom of this page also has an overview of the setup process.)

  • Using the bars in your phone’s notification area, find the location in your house with the best cell coverage. (The instructions in our Cell Signal Strength article can help you with this.) Make sure a 4G LTE icon is displayed on your handset.
  • Plug in the Cel‑Fi DUO+ Network Unit inside your home, with the display facing inside the house, near the area with the strongest 4G LTE signal. (This will probably be near a window or exterior wall.) Make sure the Network Unit’s display shows at least one bar of signal. If the Network Unit’s reception is poor, try placing it in different areas in your home.
  • Plug in the Cel‑Fi DUO+ Coverage Unit inside your home, as far as possible from the Network Unit or where you need improved coverage the most. The numeric display on the Coverage Unit will cycle for a few minutes before settling in on a final number between 0 and 9. The higher this number, the better the coverage the DUO+ system will provide. If the number on the Coverage Unit is less than 8, try moving it to different places in your home until you get an 8 or 9 on the display.
  • That’s it! You may leave the DUO+ Network Unit and Coverage Unit standing upright on a flat surface, or mount either or both of them to a wall with the included hardware.

How it works

The Cel‑Fi DUO+ Wireless Smart Signal Booster system’s Network Unit receives the outside cell signal and wirelessly transmits it to the Coverage Unit. The Coverage Unit amplifies the signal and broadcasts it inside your home. This allows you to stay connected in locations where cell service is poor or where your home’s construction materials interfere with signals from the local cell tower.

Works on the Verizon network only

This Cel‑Fi DUO+ Wireless Smart Signal Booster system only works with 4G cellular bands licensed by Verizon. It will not improve 3G signal strength or work with AT&T, Sprint, U.S. Cellular, and other cellular networks.

The DUO+ supports up to three cellular bands and relays two simultaneously:

  • 700 MHz (SMH) band 13.
  • 1900 MHz (PCS) band 2.
  • 1700/2100 MHz (AWS) band 4.

It does not amplify 700 MHz bands 12 or 17, 800 MHz (Cellular) band 5, or 1900 MHz (Extended PCS) band 25.

How much area will this product cover?

The Cel‑Fi DUO+ Wireless Smart Signal Booster is designed to amplify cellular transmissions inside a home, large condominium or apartment, or similar space.

The DUO+ Coverage Unit will broadcast improved cellular signal in spherical pattern. The broadcast distance depends on many factors, including inside building materials (cell signals pass through wood framing and drywall more easily than through steel and concrete) and which cellular frequencies are being boosted (lower-frequency 700 MHz signals travel farther than higher-frequency PCS signals.)

Powerful Signal has over a decade of experience designing and installing cellular amplification systems. Please call us at 866‐912‐3444 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.
