Anyone with a mobile phone is aware of the issue of low or no signal. Modern office buildings with complex electrical and climate efficient infrastructure often drown out signal, while rural locations and even urban homes can suffer from lack of mobile signal depending on their proximity to the nearest transmitter. CEL-FI has developed a range of easy-to-install OFCOM licence exempt products that amplify the mobile signal within the building. Multiple users can now make and receive calls and browse the internet with strong and reliable connectivity, whilst conserving their mobile device’s battery power as it is not having to work so hard.

CEL-FI is the perfect solution for small and medium sized businesses that lose valuable working time through missed calls, dropped calls and staff having to move away from work stations to make a simple call. Once installed, the system is seamless and integrates with the existing mobile infrastructure.

Whether working from home, in a factory or in a big office environment, having a reliable signal saves both time and money. All that is required is a single bar of signal to get up and running, as CEL-FI products then amplify that signal to full strength for increased and more reliable coverage.

Why is CEL-FI better than using WiFi calling? Because once you walk away from the WiFi signal, the call is dropped, keeping you tethered to your location. This is not the case with CEL-FI, as it uses the cellular signal, allowing calls to be continued once on the move.

Products are available for all the UK’s major Networks – Vodafone, O2, EE and Three (and associated MVNO’s) - and the CEL-FI Wave app allows users to switch networks depending on their requirements, and therefore future proofing the customers investment. In locations where all Networks require amplification, such as office blocks, leisure locations or factories etc, multiple CEL-FI units can be installed.

The range consists of four products starting from £399 with the CEL-FI Prime. Ideal for 1 or 2 bed flats and small homes, all that is required is the installation of a receiver that is then wired to the transmitter in the most central location. The CEL-FI Pro is a simple plug-and-play solution, which is suitable for large homes and SME’s. As the receiver and transmitter connect together wirelessly, no installation is required. The CEL-FI Go X (IP66 Rated) is perfect for larger homes and small to medium sized businesses, as its range is increased to 1,500m2. For larger corporate spaces, there is the CEL-FI Quatra, which is a scalable system that requires low-cost Cat5e cable for installation.

Significantly cheaper than DAS (Distributed Antenna Systems) installations, which use expensive co-ax cable, the Quatra can even use existing point-to-point cable installed within the buildings infrastructure.
CEL-FI products are easy to install and use. All that is required is a single bar of coverage and installation of the antenna or unit where mobile signal coverage is at its best. Each product is OFCOM licence exempt so there is no need for any form of subscriptions or contracts.

CEL-FI products conform to specific requirements and specifications set by OFCOM. They can be purchased without the need for any licence and can be legally used in the UK since April 2018. Alternative products are available on the market but they do not conform to OFCOM’s specifications. Users can face heavy fines and even imprisonment for inappropriate use, as these cheaper alternatives have been known to take down the local cellular mast, causing wide disruption to the mobile signal in the local area.
