Cel-Fi PRO improves 3G, 4G, and LTE cellular service by eliminating dead zones and dropped calls. With 100 dB of gain, Cel-Fi PRO will not only improve cellular service across four (4) concurrent bands, it will also reduce your cell phone’s power requirements and extend its battery life. Cel-Fi PRO covers up to 13,000 ft2 (1,200 m2) of indoor space per system. Cel-Fi PRO systems feature an LCD color interface, are fully self-contained and self-configuring, and require no external antennas or wiring. Simply plug it in to boost indoor cellular coverage.


Cel-Fi PRO is CE and FCC approved. It has been approved by numerous mobile operators and regulatory bodies and is shipping globally.

Cel-Fi PRO EXA variants feature an external antenna connector to enable the use of an external Donor antenna. A Cel-Fi PRO EXA with an external Donor antenna can thereby acquire an outside signal, allowing it to be used in applications where no signal is present indoors (i.e. cement, metal walls, etc.). This opens up new opportunities for using Cel-Fi PRO Smart Boosters when other solutions fail. Cel-Fi PRO EXA enables cellular coverage in hard to reach places by allowing the Cel-Fi Network Unit to be placed, where no service exists.

Move the CU further away from the NU to maximize coverage.

The total coverage area equals twice the distance between the NU and the CU. The maximum distance is up to 100 dB path loss.

Get setup in 4 easy steps

1. Find the best cellular signal

Use your phone to find the best cellular signal. Typically you will get the best signal near a window.

2. Place the Network Unit

Place the Network Unit (NU) in the location where you get the best cellular signal.

3. Place the Coverage Unit

Place the Coverage Unit (CU) in the location where you need improved coverage.

4. Use app to optimize setup

Using the Cel-Fi WAVE app, finish setup and activation.

Antennas & Accessories

Cel-Fi PRO X

Cel-Fi PRO X is a cable adapter sleeve that allows the Cel-Fi PRO unit to link across greater distances or through (RF blocking) obstacles. The accessory works with any Cel-Fi PRO, in locations where the standard wireless UNII system link is challenged. The Cel-Fi PRO X connects the Cel-Fi PRO Network Unit to the Cel-Fi PRO Coverage Unit using a completely passively coupled sleeve, which uses the cable for communications.

Cel-Fi PRO X opens up new opportunities for using Cel-Fi PRO Smart Boosters, when other solutions fail. Cel-Fi PRO X enables cellular coverage to hard to reach places by allowing the Cel-Fi Coverage Unit to be placed much further from the Network Unit, or allowing the Units to connect when their normal RF link signals cannot penetrate through structures.
