Anyone with a mobile phone is aware of the issue of low or
Modern office buildings with complex electrical and climate efficient infrastructure often drown out signal, while rural locations and urban homes can suffer from lack of mobile signal depending on their proximity to the nearest transmitter.
CEL-FI says it has developed a range of easy-to-install
OFCOM licence exempt products that amplifies the mobile signal within any
building, allowing multiple users to make and receive calls and browse the
internet with strong and reliable connectivity, whilst conserving their mobile
device’s battery power.
So why not just use the building’s Wi-Fi? CEL-FI argues its
solution is better because once a user walks away from the Wi-Fi signal, the
call is dropped, keeping people tethered to the location.
This is not the case with CEL-FI, as it uses the cellular signal,
allowing calls to be continued once on the move.
CEL-FI says its product range is suitable for work or home
situations and is amongst the most cost-effective ways of addressing the
universal challenge of poor mobile signal coverage at work or home.
Unconditionally network safe, with a strong coverage
footprint and multi-network approved for 3G/4G/LTE voice and data, all CEL-FI
products comply with OFCOM regulations (OFCOM SI 2018/399) and can be used
without a licence.
CEL-FI argues its products are a good solution for small and
medium sized businesses that lose working time through missed calls, dropped
calls and staff having to move away from work stations to make a call. Once
installed, the system is seamless and integrates with the existing mobile
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 CELFI units can
The range consists of four products starting from £399 with the CEL-FI Prime suited for one or two 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 suited 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.
Cheaper than DAS (Distributed Antenna Systems)
installations, which use coax cable, the Quatra can also use existing
point-to-point cable installed within the buildings infrastructure.
CEL-FI says its 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.
The maker underlines that each product is OFCOM licence
exempt so there is no need for any form of subscriptions or contracts.
