Cel-Fi PRIME is the perfect mobile signal booster for smaller spaces of 1,200 ft² / 110m², like flats, apartments, storefronts, kiosks, home offices or similar spaces. 10x stronger than traditional analogue boosters, it strengthens 3G and 4G signal coverage for voice and data.

With 80dB of gain, Cel-Fi PRIME will reduce the mobile device’s power requirements and extend its battery life. It offers plug-and-play mobile signal coverage, enabling clear and reliable connections within a coverage area of up to 100m2 (approximately 1,000 ft2). In an open space, the coverage bubble can be much larger.

How does it work?

Cel-Fi PRIME improves the 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 indoors. The Cel-Fi PRIME collects the best mobile signal, amplifies the signal, and rebroadcasts it inside the flat, apartment or storefront.
