The Cel-Fi GO X bundle is the best solution to improve mobile signal coverage in a rugged environment. The Cel-Fi GO X coupled with industry-leading omni and directional antennas creates a powerful carrier-class indoor mobile coverage solution which provides 100dB of signal gain covering indoor areas or up to 15,000 ft² / 1,400 m² per system. 

This multi-carrier solution is ideal for use in commercial properties, government buildings, agricultural settings, small manufacturing operations, rural areas, businesses, and large homes.

How does it work?

Cel-Fi mobile signal boosters improve signal between a mobile phone and a mobile network tower, allowing you to have clear voice conversations and a stable data connection when you are inside. An external donor antenna collects the best mobile signal from outside and transmits it to a mobile signal booster unit. The unit strengthens the signal and rebroadcasts it inside the building via internal donor antennas.

Cel-Fi GO X can be set up in five easy steps with the help of an installer.

  1. Install the Donor Antenna (Wideband Directional Antenna) outside the building, pointing it towards the nearest cell mast. There is an antenna positioning test on the Cel-Fi app, under the Settings> Antenna Settings, this will help to find the best position for the antenna.
  2. Install the Server Antenna (Wideband Indoor Omni Antenna) in the area of the building where the signal is most required.
  3. Mount the Cel-Fi GO X unit near a power outlet.
  4. Connect the antennas to the unit.
  5. Finally plug in the Cel-Fi GO X and monitor/optimise using the WAVE App.
