Cel-Fi PRO improves 3G, 4G and LTE cellular service by eliminating dead zones and dropped calls. With 100dB of gain, Cel-Fi PRO will not only improve cellular service across four (4) concurrent bands, it will also reduce your cell phone’s power requirements and extend its battery life. Cel-Fi PRO covers up to 13,000 sq. ft. (approximately 1,200 m2) of indoor space per system. Cel-Fi PRO systems feature an LCD color interface, are fully self-contained and self-configuring, and require no external antennas or wiring. Simply plug it in to boost indoor cellular coverage.
Cel-Fi PRO is CE and FCC approved. It has been approved by numerous mobile operators and regulatory bodies, and is shipping globally.
Cel-Fi PRO is a simple mobile phone signal booster that strengthens your 3G or 4G signal coverage. Perfect for the home or office, this compact technology allows you to boost your 3G voice and data as well as 4G data coverage inside, allowing support for up to 20 devices simultaneously.
The Cel-Fi PRO has four internal antennas built in to the units, and an external antenna port that allows for connection to an aerial (additional aerial cable not included). The multi-directional technology seeks to find the best signal and adjust to it accordingly.
Install in minutes
Installing this indoor mobile phone signal booster requires no technical knowhow, there are no complex manuals to read - it's as simple as plug-in and play.
Two units communicate wirelessly
Cel-Fi PRO consists of two units: the Window Unit (WU) and the Coverage Unit (CU). The WU sits near a window or in an area of the building that has the strongest signal from your network provider. The CU is then placed in the centre of the home or where the signal is used most.

Extends your battery life
When your phone isn’t using battery to search for signal, it can save battery life for the fun stuff like downloading, making calls and taking pictures and videos.
Unlike other signal boosters on the market, Cel-Fi works to boost your O2 network coverage without interfering with the network’s overall performance.
Cel-Fi systems are powered by IntelliBoost, two custom-designed core processors that specifically work to optimise indoor reception for both 3G and 4G in real-time. It provides intelligence to the Cel-Fi system and automatically adjusts itself to ensure you are always getting the best coverage.
Please note: Whilst Cel-Fi is allowed by Ofcom, Cel-Fi devices are ultimately under the control of O2. Software features allow the network to monitor Cel-Fi systems. O2 are able to disable Cel-Fi devices in a particular area, without any user input.
Cel-Fi PRO supports 3G and 4G signal only.
