What is Cel-Fi?

Cel-Fi PRO is a simple mobile phone signal booster that strengthens your 3G or 4G signal coverage indoors. Cel-Fi can create a large coverage bubble which automatically adjusts to the size of the indoor environment served - making it ideal for multi-story homes and medium sized businesses. It also increases Radio Frequency (RF) network capacity for mobile operators, eliminating the possibility of interferences to the mobile operator's spectrum whilst allowing support for up to 20 devices simultaneously.

How it works?

Poor reception of wireless signals indoors can be affected by several factors. These include buildings, trees, natural obstacles and the distance from the network tower. Cel-Fi is an innovative solution that improves indoor coverage by capturing the weak signal that reaches the building, improving it and retransmitting the signal indoor via the Coverage Unit.

Cel-Fi's unique, powerful and advanced technology ensures it outperforms traditional signal boosters:

Multi-core Processor - runs advanced digital echo cancellation and channel select filtering algorithm.

Complex smart antenna technology - maximises system gain and provides improved coverage and signal quality.

Sophisticated intelligent software algorithms - Cel-Fi incorporates sophisticated Self Organising Algorithms which consistently and intelligently alter their status to maximise real-time coverage and adjust to the size of the indoor environment served.

Self-adjusting technology - built-in chip automatically selects the correct frequencies for your carrier.

Wireless Connection is Unconditionally Network Safe:

With a patented 5GHz wireless link between the two units, high quality data and voice transmissions are secure and almost instantaneous. The signal booster provides security to networks by eliminating the possibility of interferences for the network provider.

Antenna technology:

The Cel-Fi PRO has intelligent 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.

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.

Faster downloads:

Get more from your smartphone with faster downloads, smoother streaming and improved voice coverage.

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.

Three Specific:

Unlike other signal boosters on the market, Cel-Fi works to boost your Three 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: Currently available for UK networks only. European suitability coming soon.
