Product description

The Cel-Fi GO X is an in-building signal booster system with up to 100dB of gain. The GO X uses Nextivity’s Cel-Fi Smart Signal Booster technology to significantly boost voice and data coverage for 3G, 4G, and LTE. It is ideal for use in large homes, businesses, retail, hospitals, warehouse and other industrial properties,  commercial properties, government buildings, agricultural settings and rural areas.

The Cel-Fi GO X connects to the Donor (outside) Antenna to draw in a cellular signal from the macro network. The GO X finds the appropriate cellular signal, improves the signal, and amplifies it. This boosted service is provided to the user via the Server (inside) Antenna.

Please note that the Cel-Fi GO X boosts one network at a time. If you have multiple people on multiple networks in your building, you may need a multi-carrier booster. The GO X does support carrier switching.

The GO X is NEMA 4 weather resistant. This rating offers protection against falling dirt and windblown dust, and water such as rain, sleet, snow, and hose directed water. The unit will be undamaged by the external formation of ice on the enclosure.

Cel-Fi WAVE Mobile App

The GO X can be easily optimized and monitored by Cel-Fi’s unique WAVE platform. Cel-Fi WAVE is a smartphone app that will help you get the best performance from your Cel-Fi GO X. The WAVE app is available for iOS and Android. The WAVE provides a User Interface to Cel-Fi systems. The app’s dashboard shows the system “Boost” value. It allows you to monitor signal gain the GO X is providing.

How it works

how a cell phone booster works
1 - Outdoor antenna

The outdoor antenna receives and transmits signal to nearby cellphone towers. Outdoor antennas can be either directional or omni-directional.

2 - Cellular amplifier

The amplifier (or "repeater") boosts the signal coming to and from and going to the cell phone tower. The "gain" of the amplifier describes how strong the amplification is - you'll see that word scattered across our product pages.

3 - Indoor antenna

The indoor antenna rebroadcasts the signal inside the building. Some kits have more than one indoor antenna to help distribute the signal.


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 15,000 sq. ft. coverage
Medium outdoor signal (3-4 bars) up to 10,000 sq. ft. coverage
Weak outdoor signal (1-2 bars) up to 5,000 sq. ft. coverage


Like almost all of our products, the Cel-Fi GO X can be installed by anyone who feels comfortable doing simple home repairs and running cabling. If you’re not comfortable doing that kind of work, you might consider finding a local electronics installer or asking a friend.
