What our customers say

    “We moved into a new office in Central London. Despite the central location of the building, there was no mobile signal inside the building. It was very frustrating to step outside into the noisy, busy street to make and receive phone calls. Dropped and missed calls were having a detrimental effect on our business and staff morale.

    Frequency presented us with a lawful, cost-effective solution to bring us an in-door mobile signal. In less than 1 week, in-door connectivity was provided on EE, Three and O2 networks. The reception has completely improved. We are delighted with the solution, thank you." Joe Bonner, Director Henry Construction
    “Cel-Fi GO M provided essential mobile connectivity to the BRX Bahrain Raid Xtreme team in their pursuit of victory at the 43rd Dakar Rally in 2021. The BRX support team followed the racing teams in an HGV race office and two management cars. The race office carried the control centre and communication hub from where the core support team had an overview of the entire event. Good connectivity was critical to ensure that there is always reliable two-way communication available to ensure that support could be carried out timeously and effectively. Due to the materials used in the build of the race office, mobile signal was unable to penetrate the body of the vehicle. The Cel-Fi GO M in-vehicle signal booster proved to be the ideal solution to overcome the signal issues within the race office and provided the team with clear and robust mobile connectivity throughout this epic edurance event."

    We are very impressed with the Cel-Fi GO M solution and will be looking at some more units for the other vehicles. "Allan McGuinness, Prodrive Manager
    Welsh Ambulance

    “The Welsh Ambulance Services NHS Trust moved to a newly refurbished, contemporary two-storey office block on St Asaph Business Park in Ty Elwy in May 2019. It was only once we moved in that we realised that mobile signal coverage for Vodafone and EE were practically non-existent. In our line of work, staff rely heavily on the use of their mobile devices to perform their duties and this put us at great risk.

    Frequency Telecom commissioned and installed the Cel-Fi QUATRA mobile signal booster within days, without the need for any operator licence. Vodafone and EE users reported a steady 4 to 5 bars of mobile signal in key areas of the business. Productivity soared as staff were able to perform their duties optimally.

    We’re very happy with our Cel-Fi deployment to enhance the Vodafone network in our HQ. We were very impressed with the complete package provided by Frequency Telecom and Cel-Fi, the manufacturer.” Tony Raine, Network & Telecommunications Manager

    “When we built the new wing of Bronglais General Hospital, it was apparent that the EE mobile signal was poor and staff were complaining of not being able to use their mobile phones. We had previously tried network provided boosters, but they didn’t provide to the scale of building and volume of users required. WiFi calling was not effective enough resulting in further complaints from staff and other hospital users on EE.

    Following a site inspection, Cel-Fi QUATRA mobile signal boosters were fitted. This solution resolved the EE mobile coverage issues in the existing and new wing of the building. Staff are confident that they are always contactable. Since the system was fitted, the mobile signal has gone from zero to a steady two-three bars.

    It’s been a life saver for us. If any of the other Health boards want to ask about the kit, I will be happy for you to forward my email address onto them.” Pete Evans, Infrastructure Technician Hywel Dda University Health Board

    “When OFCOM found and removed a non-compliant mobile signal booster in our building, the HQ of the RDaSH NHS Foundation Trust was left without mobile signal coverage in key areas. This put us in a precarious position as mobile connectivity is essential to provide our services to staff and visitors. Everyone complained to our IT team about the inferior service and its ensuing impact on our hospital. We needed to find a legal solution that could be implemented quickly.

    Following several consultations detailing the incumbent solution, it was determined that the Cel-Fi GO X mobile signal booster would be compatible with much the infrastructure that was already in place, which lead to a speedy turnaround and installation. The Cel-Fi GO X solution has eliminated dead zones and dropped calls and has provided us with clear and reliable connections.

    Cel-Fi has significantly improved the signal in parts of the building where it’s deployed. We will look to buy additional boosters to cover other areas of the hospital. We are happy for you to reference our Trust as a user when getting enquiries from other Trusts.” Ian Higgins, Estates Department RD&SH NHS Trust

    “One of our key serviced offices in Nottingham is in a mobile network blackspot, affecting the whole building and with all 4 of the main UK Mobile networks providing little to no coverage internally. As a result, our customers had been complaining on a daily basis of poor connectivity and difficulty conducting their business.

    Having previously tried Wi-Fi calling and network specific boosters, results were intermittent and unreliable, so we needed a robust, corporate solution that required minimum attention from us as landlords and provided our customers with full mobile network coverage over all 4 networks.

    Our Supplier provided a full in-depth site survey, recommending that we use their Cel-Fi GO-X products around the building. The results were instantaneous – areas of the building that previously had low – to zero coverage now had full signal strength, resulting in 100% positive feedback and many happy customers! We are now working with the Supplier to improve connectivity at multiple offices Nationwide.” Stephen Day, NW UK IT Manager Pure Offices
    Buckinghamshire New University

    “Bucks New University’s educational facility in Aylesbury had very poor mobile phone reception on all operators (Vodafone, O2, Three and EE) within the building and so they asked us to resolve. Of particular importance to the client was the need to deploy a legal solution, compliant with OFCOM regulations (OFCOM SI 2018/399) and which could be used without the need for an operator licence.

    ITC Concepts, working on behalf of Bucks New University, engaged with Frequency Telecom - the leading master distributor of the only OFCOM License Exempt Mobile Signal Boosters in the UK, with a requirement to provide a multi-network mobile signal booster solution.

    The Supplier came in at very short notice, carried out an onsite mobile signal survey – which confirmed the concerns, came up with a cost effective proposal to overcome the issue and in what was literally a couple of weeks, installed the Cel-Fi Quatra solution to enhance the mobile coverage so that mobile devices from any network can now be used within the building with no issues.” Ian Evans, Director ITC Concepts Buckinghamshire New University

    “I called Frequency, the UK Distributor for Cel-Fi, and spoke with Colin Giles (Account Manager and Cel-Fi expert), who pulled out all of the stops to understand the mobile signal connectivity issue and its impact on our business.

    He recommended Cel-Fi Go X solution that is fully compliant with OFCOM regulations (OFCOM SI 2018/399) and can be used without a licence and does not interfere with other wireless devices.

    We only had a limited time to solve the problem, so we not only needed a system that worked, but we needed it fast. Colin and his team did not let us down, implemented the solution within 3 weeks and we can now deliver the right level of connectivity our customers expect.” Jayne Southall, CEO Lincolnshire Agricultural Society
