Nextivity CEL-FI | SOLO

The Nextivity CEL-FI SOLO is the most powerful carrier-grade solution available to improve mobile coverage in indoor areas of up to 16,000 ft² /1,500 m² per system. With 100dB of gain, it eliminates dead zones and dropped calls by amplifying 3G / 4G / 5G mobile signal for voice and data.

Nextivity CEL-FI SOLO is the ideal solution for commercial properties, government buildings, small manufacturing, warehouses, offices, retail outlets, rural areas, 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.
