Cel-fi Duo+ Signal Booster Details

The Cel-Fi DUO+ Smart Signal Booster for Verizon and T-Mobile by Nextivity is part of the next generation of intelligent signal boosters. All Cel-Fi products are designed and developed using the most advanced radio frequency and signal processing technology.

It greatly enhances 4G, LTE, and 3G cell service for all your wireless devices (smartphones, notebooks, hotspots, etc.) on Verizon and T-Mobile for any home or office up to 13,000 sq ft.

The Cel-Fi DUO+ has several advantages over traditional signal boosters:

  • Plug and play setup: just plug in the Network and Coverage units and get better signal.
  • Monitor performance with the Cel-Fi WAVE app.
  • Extreme power good for everything from apartments to large homes.

Unlike multi-carrier signal boosters with a limit of +70 dB, Cel-Fi’s single-carrier solution can boost signal up to +100 dB. That’s a difference of +30 dB or up to 1000x more power compared to multi-carrier boosters.

Eliminate dropped calls, slow data, and poor Verizon and T-Mobile signal from your life with a Cel-Fi PRO Smart signal booster.
