In-Store Cellular Coverage Upgrades

Pan RF and Nextivity Has Roll Out CEL-FI Across 400+ Stores

Pan RF and Nextivity deployed in-building cellular coverage across more than 400 UK stores and regional distribution centres for a German discount grocer, using CEL-FI technology to restore reliable multi-operator 4G and 5G service indoors. The deployment addressed signal loss caused by energy-efficient materials such as Low-E glass, steel and concrete that can prevent shopper devices from communicating effectively with outside towers.

The programme used preconfigured, repeatable designs with overnight installation and remote optimisation to avoid trading disruption. Front-of-house antennas were installed after hours, with commissioning and testing completed before stores reopened. Performance was evaluated against commercial metrics including loyalty app engagement, digital coupon redemption and checkout transaction speed.

For retailers, stronger cellular coverage removes friction around app loading, mobile payments and banking authorisations. The project also demonstrated a business case for treating connectivity as loyalty infrastructure, with capital payback reportedly achievable within a few months.
