The Cel-Fi PRO Smart Signal Booster for AT&T 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 AT&T for any home or office up to 13,000 sq ft.
The Cel-Fi PRO 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 AT&T signal from your life with a Cel-Fi PRO Smart signal booster.

Frequently Asked Questions
There are a few things to consider before setting up your Cel-Fi PRO.
First, locate the area in your home with the strongest cell signal. Preferably, this on the second or third story near a window. Place the Network Unit there, and plug it in.
Second, find an area as far away as possible, preferably with some vertical separation, from where you placed the Network Unit. Place the Coverage Unit there.
Setting up with the App
Now that you’ve physically set up the PRO, you’ll need to activate it with the Cel-Fi WAVE app.
- Register your booster. This is a legal step and will tie your app to your booster.
- Enjoy your boosted signal!
The app has many other features, allowing for remote monitoring, optimal antenna setup, and more – however, these features are all optional.
The Cel-Fi PRO creates a “bubble” of strong signal between the two units, so make sure there is as much separation as possible.
Should you switch to Verizon, T-Mobile, Sprint, or ay other major carrier, you’ll need to switch boosters. For that, check out the Cel-Fi DUO+.
Place the Network Unit in the place where signal is strongest, as high as possible.
Place the Coverage Unit as far away as you can from the Network Unit, with 100 dB of loss being the maximum distance away they can be placed.
We provide a 30 day money back guarantee and a two-year warranty on all Cel-Fi PRO units.
