Product Description

The Cel-Fi PRO is a powerful signal booster system that boosts 3G/4G/LTE voice and data for AT&T. The Cel-Fi PRO offers up to 100 dB of gain and coverage up to 13,000 sq ft.

The Cel-Fi PRO system is incredibly easy to set up. The simple plug and play installation means that anyone can install the device. There are no external cables, antennas, wires, or drills needed. The units simply plug-in to power.

The Cel-Fi PRO has an LCD color interface and is fully self-contained and self-configuring. It supports the Cel-Fi WAVE mobile application.

Cel-Fi WAVE Mobile App

Cel-Fi WAVE is a smartphone app that will help you get the best performance from your Cel-Fi PRO. The WAVE app is available for desktop, iOS, and Android. The app’s dashboard allows you to optimize setup and download software updates.

The Network Unit (NU) should be placed where the existing cellular signal is best (generally by a window). The Coverage Unit (CU) should be placed in the location you need improved signal. You can optimize coverage by moving the CU. The NU and CU communicate with each other wirelessly to provide the best signal improvement possible. As the distance between the units is increased, the CU adjusts its coverage bubble to provide the ideal amount of coverage.


Mounting brackets and hardware are provided to mount both (or either) the Coverage Unit and the Network Unit. The brackets come equipped with screws and inserts for mounting in standard drywall. The Network Unit has mounting holes on the back. The Coverage Unit has mounting holes on the bottom and on the back. The holes on the bottom of the Coverage Unit can be used for mounting the Coverage Unit to a ceiling.


The coverage area you can expect from any signal booster kit depends on the signal strength outside the building.

Outdoor Signal Estimated coverage area
Strong outdoor signal (5 bars) up to 13,000 sq. ft. coverage
Medium outdoor signal (3-4 bars) up to 8,000 sq. ft. coverage
Weak outdoor signal (1-2 bars) up to 5,000 sq. ft. coverage
