Nextivity CEL-FI | GO X

The Nextivity CEL-FI GO X is the best solution to improve mobile signal coverage in a rugged environment. The Nextivity 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.

Nextivity 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.
