Private Mobile Networks for Warehouses and Logistics

Posted by on

Warehousing and logistics operations are undergoing rapid transformation as businesses strive to meet growing customer expectations and increasing operational complexity. The adoption of Industry 4.0 technologies, including IoT sensors, autonomous robots and smart shelving, is driving new levels of automation and efficiency. However, these innovations are only as effective as the connectivity that underpins them. For warehouses and logistics facilities to fully realise their potential, they require secure, high-capacity, low-latency and ubiquitous wireless networks. This is where private mobile networks (PMNs) have emerged as a decisive enabler.

A private mobile network provides dedicated connectivity that is resilient, flexible and capable of scaling with business growth. Unlike traditional Wi-Fi or public mobile networks, PMNs are tailored to the unique requirements of a facility, offering predictable performance, reliable coverage both indoors and outdoors, and enhanced security. These characteristics make PMNs particularly suited for modern warehouse and logistics environments where efficiency, safety and precision are paramount.

While we have covered this topic in previous posts, BAI Communications recently shared further insights and an infographic on how PMNs can support the sector. Their examples, although focused on Australia, are highly relevant to warehouse and logistics operations worldwide.

  • Automation and robotics at scale

Automation is becoming the backbone of warehouse efficiency. Automated storage and retrieval systems (ASRS) allow fast and accurate handling of goods, optimising space and speeding up order fulfilment. These systems require dependable connectivity for configuration, remote management and fault resolution. A PMN provides predictable coverage across the facility, eliminating bottlenecks caused by inconsistent signals.

Autonomous mobile robots (AMRs) highlight the importance of reliable networks. Controlled by centralised fleet management systems, AMRs move goods across shelves, packing stations and loading areas. Any loss of connectivity risks errors and delays. A PMN ensures low-latency coordination and smooth handovers, avoiding the dropouts often seen with Wi-Fi. This provides stability not only for routine operations but also during peak periods, where uninterrupted robotic performance is essential.

  • Real-time asset tracking

The ability to locate goods, vehicles and equipment in real time is fundamental to warehouse efficiency. Asset tracking systems powered by PMNs deliver continuous monitoring throughout a facility, using IoT sensors and smart tags to provide live updates on every item. This reduces the risk of misplaced stock, prevents losses and supports accurate inventory control.

Where traditional wireless solutions often fall short in large or complex sites, PMNs provide robust coverage across both indoor and outdoor areas. This ensures that every asset is visible throughout its journey, from arrival at the dock to final dispatch. The result is improved accountability, optimised workflows and faster response when exceptions occur.

  • Digital twins for operational intelligence

Digital twins are gaining traction in logistics as a way to create a virtual model of the warehouse environment. By combining inputs from sensors, cameras and IoT devices, a digital twin gives operators real-time visibility and allows predictive analytics for smarter decision-making.

To achieve this, the network must handle thousands of data streams simultaneously with very low latency. PMNs provide the wide coverage, capacity and secure connectivity required for such an environment. This enables constant synchronisation between the physical warehouse and its digital twin, supporting scenario testing, predictive maintenance and continuous optimisation.

  • Security and monitoring through CCTV

Safety and security are core concerns for warehouses. CCTV systems depend on uninterrupted, high-quality video streams to monitor operations and detect anomalies. Fixed cabling offers reliability but is expensive to install and inflexible, while Wi-Fi may lack the uplink capacity for multiple high-definition cameras.

PMNs solve this by providing dedicated, high-speed connectivity that can be scaled for video requirements. Cameras can be placed wherever needed without physical constraints, offering real-time visibility across the site. From identifying equipment malfunctions to responding to unauthorised access, a PMN-backed CCTV system strengthens both safety and resilience.

  • Supporting connected workers

Even as automation expands, human workers remain essential. PMNs enhance their capabilities by ensuring reliable mobile connectivity for scanners, handheld devices and push-to-talk communication. This keeps staff connected across the entire site, reducing delays and supporting coordination.

PMNs also enable advanced applications such as vision-picking through augmented reality glasses. Workers can follow visual overlays that guide them directly to items, improving accuracy and reducing picking times. Reliable coverage further enhances worker safety, ensuring communication is always available during routine operations or emergency situations.

One of the most powerful advantages of PMNs is scalability. As operations expand or new technologies are introduced, PMNs can accommodate additional devices and applications without degrading performance. This flexibility allows warehouses to evolve without being constrained by their connectivity.

At the same time, PMNs offer robust security features such as encryption and access controls to protect sensitive operational data. For logistics companies handling valuable goods and customer information, this is a critical safeguard.

As global supply chains grow more complex and customer expectations continue to rise, reliable connectivity will be central to maintaining efficiency and competitiveness. By enabling automation, asset tracking, digital twins, CCTV and connected workers, PMNs are proving to be the digital foundation of modern warehousing.
