Supporting refrigerated warehouse monitoring for a large UK retailer

A large UK retailer needed reliable connectivity for monitoring equipment installed within its refrigerated warehouse estate.

Each refrigerated unit is a substantial operational environment, with some covering an area of around half a football pitch. The monitoring equipment needed to send key data reliably, including temperature readings, door-open events and temperature drops.

Active Digital supplied multi-network SIM connectivity for around 85 refrigeration monitoring units. This gives the retailer’s monitoring devices access to more than one UK mobile network, helping to reduce dependence on a single carrier and support the continued flow of data from its cold-storage operation.

Our Solution

Active Digital deployed multi-network SIM connectivity across approximately 85 large refrigerated warehouse monitoring units.

Each SIM connects the installed monitoring equipment to the relevant data platform, allowing the retailer to receive information from across its refrigerated estate. The devices track temperature, door-open events and temperature drops, supporting the visibility needed to help protect food quality.

The multi-network approach was selected to provide stronger coverage options for a large, distributed connected-device estate. Rather than relying on a single mobile network, each monitoring unit can use available network connectivity according to its configuration.

The solution includes:

Multi-network SIM connectivity for around 85 refrigerated monitoring units

Connectivity for substantial refrigerated warehouse environments

Support for temperature monitoring and reporting

Data transmission for door-open events

Visibility of temperature drops

A connected-device model designed to reduce dependence on a single mobile network

The challenge

The retailer needed a dependable way for monitoring equipment to send data from its refrigerated warehouse environment.

Cold storage operations depend on accurate, timely information. If a monitoring device cannot communicate, teams may have less visibility of temperature changes or access events within the refrigerated unit. For a large estate, managing connectivity consistently across every monitoring device also becomes an operational consideration.

The retailer needed support with:

Connectivity for around 85 refrigeration monitoring units
A solution suited to large warehouse and cold-storage environments
Continued transmission of temperature data
Visibility of door-open events and temperature drops
Reduced reliance on one mobile network
A consistent connectivity model across the estate

The outcome

The large UK retailer now has multi-network SIM connectivity in place across around 85 refrigerated warehouse monitoring units.

The connected monitoring equipment can send data on temperature, door-open events and temperature drops to support oversight of the retailer’s cold-storage operation. This helps the business maintain visibility of the conditions that matter to food quality across its refrigerated warehouse estate.

By providing access to more than one UK mobile network, the solution also gives the retailer a more resilient connectivity model than a single-network approach.
