Cel-Fi GO X smart signal boosters strengthen indoor 3G/4G/5G signal coverage with up to 100dB for the best voice and data wireless performance. The Cel-Fi GO X has a rugged design to withstand harsh conditions including dust and water exposure. Cel-Fi GO X utilises nanotechnology to produce a thin film coating across the entire PCB assembly. This coating, combined with an industrial design for harsh conditions, enables the device to support weather conditions that include water, dust, and dirt.

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 server antennas. For best results, separate the donor and server antenna(s) as much as possible.

  • 1 x Cel-Fi GO X Smart Signal Booster

All compatible Antennas for the Cel-Fi GO X are available to purchase separately.

The Cel-Fi GO X works best when combined with a wideband omni donor antenna and a wideband panel server antenna.

The Cel-Fi GO X is cost-efficient, easy-to-setup with an installer and can be managed and monitored by using the Cel-Fi WAVE App.
