Mobile signal improvement in a regional supermarket distribution centre

Mobile blackspots in a supermarket distribution centre resolved with Cel-Fi mobile signal boosters.

During the construction of a new distribution centre in Peterborough, the customer identified that a robust and stable mobile connection would be imperative for the operational efficiency of the supermarket. Pan RF, Cel-Fi Certified and close partner of Frequency Telecom, was involved from the onset which allowed them to schedule the installation of a cost-effective mobile signal solution in a short space of time.


A new 70,000m² regional distribution centre was built for a leading supermarket in Peterborough, UK. The warehouse includes a single level office on the 3rd floor which house meeting rooms, administrative areas, training rooms and a canteen. Office space, driver check-in desks and the goods out area are located on the ground floor.

The company provide their employees with EE operated mobile phones to speak to customers and suppliers. Employees often move around the building to quieter areas or meeting rooms to have telephone conversations. It was imperative to have a reliable and stable connection in place to prevent dropped calls as they moved about in the building.

The Challenge

The main building is 242m long x 185m wide x 20m high and constructed from large span fabricated steel trusses and metal cladding. To accommodate the 3rd-floor mezzanine, long-span steel beams with metal floor decking were installed. New building regulations introduced after the Grenfell disaster stipulate that all new buildings must include more fire-stop partitions. The use of metal cladding and steel effectively blocked any mobile signal from penetrating through.

A further challenge was posed by the cable trays which were located above the suspended ceiling and would make any cable installation problematic.

The Solution

Recognizing that mobile connectivity was crucial for business operations, the customer had the foresight to involve Pan RF from the onset. Pan RF performed a site survey to establish the current level of EE mobile coverage. The site survey confirmed that there was adequate EE mobile coverage outside the building, but once inside, the signal strength declining significantly, particularly in the 3rd-floor offices and goods out areas.

The Cel-Fi Quatra mobile signal booster solution was presented to the customer to provide voice and data services on the EE network. The Cel-Fi Quatra is a hybrid, all-digital solution which combines the best of active DAS and Smart Booster technologies. Cel-Fi products have the additional benefit of being license-exempt and comply with all the OFCOM regulatory requirements in the UK.

After the acceptance of the proposal, the Cel-Fi Quatra solution was installed and commissioned using the Cel-Fi Wave Portal. Speed tests and walk tests were carried out using TEMs pocket software to provide further evidence of the improvement of coverage levels within the 3rd Floor Office and Ground Floor Goods Out areas.

This cost-effective, OFCOM licence-exempt solution was deployed in a short space of time and provided the warehouse employees with reliable voice and data services in the new facility.
