Cel-Fi by Nextivity

The most advanced technology for improving in-door mobile coverage

Cel-Fi smart signal boosters from Nextivity are the best solution on the market for addressing the universal challenge of poor in-door mobile coverage.

The Cel-Fi mobile signal booster range includes solutions for apartments or flats, small and large residential properties, storefronts, offices and commercial properties as well as large enterprise environments like distribution centres, government buildings and hospitals.

Cel-Fi products are designed to improve mobile signal strength with up to 100db gain for 3G / 4G / 5G in voice and data.

The Cel-Fi commitment is to protect the operator’s network, deliver the best mobile performance, and be the easiest solution to install.

How it works

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. An external antenna collects the best mobile signal from outside and transmits it to a mobile signal booster unit, strengthening the signal and broadcasting it internally.

Cel-Fi automatically adjusts to the size of the indoor environment and leverage the advanced signal-processing and radio design of Nextivity’s IntelliBoost chipset to deliver the industry’s highest gain at the lowest cost per square foot.

Cel-Fi is available for EE, O2, Vodafone, Three and all Mobile Virtual Network Operators. The Cel-Fi commitment is to protect the operator’s network, deliver the best mobile performance, and be the easiest solution to install.

Cel-Fi products are licence-exempt and fully comply with Ofcom’s UK Interface requirement 2102 (IR2102) (UK) and ComReg S.I.No.283 of 2018 (Ireland).
