Sweet in-building mobile signal in a Hotel Chocolat distribution centre

Stable and reliable mobile connectivity is crucial for modern day business operations. Poor indoor mobile coverage threatens productivity, revenue, reputational damage and customer satisfaction.

Despite these pitfalls, there are many businesses who neglect to address the demand for consistent and reliable indoor mobile coverage. The unfamiliar terms and technical terminology sound daunting and complex. They expect the solution to have large-scale disruption to their day-to-day operations, never mind the huge CAPEX cost.

Distribution centres have additional complexities. The sheer size of the buildings combined with the metallised insulation, steel frames and metal cladding create a classic Faraday cage setting which prevents mobile signal to penetrate the building. Often, distribution centres are found on the outskirts of town, some distance from the mobile phone masts.

When luxury chocolatier and cocoa grower Hotel Chocolat acquired the neighbouring warehouse in St Neots in August 2020, they addressed any complexities immediately. Mobile coverage in the existing warehouse was an issue prior to the extension. They had previously attempted to boost mobile signal by installing network-provided boosters. Although it initially provided some marginal improvements in certain areas of the building, there was room for improvement. After the expansion, the extended ‘Alpha’ distribution centre was over 20,000 m² in size.

With ever-increasing reliance on mobile devices together with the impact on productivity meant that the issue of in-building signal could no longer be ignored and had to be resolved.

Hotel Chocolat identified that mobile connectivity would be imperative for their operational efficiency and contacted Frequency Telecom to provide them with a legal, all network solution which covered the entire warehouse.

Frequency Telecom is the master distributor of Nextivity’s CEL-FI range of mobile signal boosters and are widely recognised as the experts in providing in-building and in-vehicle mobile signal solutions.
