Private 5G Could Solve Connectivity Challenges for Warehouse Robots

As automation expands across warehouses and retail distribution centers, the number of autonomous robots used for logistics and inventory management is rising rapidly. This surge in robotic systems is fueling strong growth in the robots-as-a-service (RaaS) industry, which analysts expect to expand by more than 30% annually through 2030. However, the increased reliance on robotics is also creating a new challenge: reliable wireless connectivity.

Traditional Wi-Fi networks long used in warehouses are increasingly struggling to keep up with the demands of large fleets of mobile robots. To address this problem, private 5G networking company Celona and connectivity provider Digi International have developed a new approach that aims to deliver stronger, more reliable wireless infrastructure for automated warehouse environments.

The companies began rolling out their next-generation RaaS connectivity system earlier this year. Their technology integrates Digi’s industrial hardware with Celona’s private 5G LAN platform, creating a dedicated wireless network that allows robots to remain connected even in large, complex facilities.

Why Warehouse Automation Needs Better Connectivity

Modern warehouses rely heavily on automation technologies such as computer vision, connected workers and autonomous robots that move products across facilities. These systems depend on wireless networks that can deliver high capacity, minimal delay and constant reliability.

Industrial routers and edge devices help bridge the gap between older equipment including programmable logic controllers and sensors and newer private network infrastructure. By linking these devices to private cellular networks, operators can deploy automated systems more efficiently and scale them as warehouse operations expand.

Reliable connectivity is essential not only for productivity but also for safety.

According to Celona’s co-founder and CTO Mehmet Yavuz, many warehouse robots currently in use do not have built-in 5G connectivity modules. As a result, additional infrastructure is required to keep these machines connected while they move throughout the facility.

From Guided Vehicles to Autonomous Robots

Warehouse robotics has evolved significantly in recent years. Earlier automated systems often relied on automated guided vehicles (AGVs) that followed fixed paths marked by magnetic tape or tracks.

Today, warehouses are increasingly using autonomous mobile robots (AMRs) that navigate independently using sensors, cameras and artificial intelligence. Unlike AGVs, these robots can dynamically plan routes, avoid obstacles and adapt to changing environments without relying on fixed infrastructure.

This flexibility makes AMRs particularly useful in large warehouses and manufacturing facilities where layouts frequently change and operations are highly dynamic.

However, this increased autonomy also requires reliable wireless communication so robots can continuously exchange data with control systems.

The “Heartbeat” Problem in Robot Fleets

Warehouse robots rely on continuous communication signals to confirm that they are operating correctly. Engineers often describe this signal as a “heartbeat.”

If the control system fails to receive this signal from a robot, it assumes that the machine may have lost connectivity or encountered a malfunction. In many systems, missing multiple heartbeat signals can automatically trigger a shutdown.

When this occurs in a busy warehouse, the consequences can be significant. Operators must locate the inactive robot on the warehouse floor, inspect it and restore connectivity a process that can disrupt operations.

As fleets grow larger, maintaining reliable connections becomes even more critical. If multiple robots lose connectivity simultaneously, productivity can decline and safety risks may increase.

Why Wi-Fi Struggles in Large Robotic Environments

While Wi-Fi works well in many stationary environments, experts say it often struggles when large numbers of mobile robots are involved.

Warehouse robots constantly move across different wireless zones. As they transition from one radio connection to another, the network must maintain a seamless link to avoid interruptions.

In facilities where robots move quickly sometimes reaching speeds of up to 30 or 40 miles per hour Wi-Fi networks may not always handle the transition smoothly.

As the number of robots increases, these connectivity challenges become more severe. Operators may find that once more than a few robots are operating simultaneously, network reliability begins to decline.

This is where private 5G networks may provide a significant advantage.

Robot Collisions and Safety Concerns

Connectivity problems can create serious safety risks in automated warehouses.

Robots often receive instructions from central control systems that direct them to specific shelves or aisles to pick up items. These instructions must be delivered quickly and consistently so that each machine knows its next task.

In facilities with hundreds of robots moving simultaneously, maintaining precise communication is essential.

If a robot loses connectivity and stops responding, it may suddenly shut down while other robots continue operating. This can create situations where machines collide or block warehouse pathways.

Such incidents could potentially damage inventory or disrupt operations.

Reliable connectivity therefore plays a critical role in preventing these situations and ensuring that robotic fleets operate safely.

The Rise of Robots-as-a-Service (RaaS)

To address connectivity challenges, Celona and Digi International developed a joint solution based on the robots-as-a-service model.

The idea behind RaaS is to simplify how companies deploy robotic systems. Instead of requiring businesses to assemble complex hardware and networking solutions themselves, the service provides a complete package that includes connectivity, management tools and infrastructure.

Through this model, companies can subscribe to a managed platform that connects their robots directly to a private 5G network.

The system combines Digi’s industrial networking equipment with Celona’s cloud-managed 5G LAN platform, creating a plug-and-play solution for large retail and warehouse operations.

This approach also helps robotic manufacturers, many of whom may not have deep expertise in cellular networking technologies.

Private 5G vs Traditional Wi-Fi Infrastructure

Warehouse operators evaluating connectivity options often compare private 5G networks with traditional Wi-Fi systems.

According to Celona’s leadership, a warehouse might require dozens or even hundreds of Wi-Fi radios to maintain adequate coverage for robotic operations.

In contrast, a private 5G network may achieve the same coverage with only a small number of radio units.

This difference can simplify infrastructure deployment and reduce network complexity.

In addition, private 5G networks offer lower latency and more predictable performance key requirements for robotics and real-time automation systems.

Studies of private wireless deployments have shown that these networks can significantly improve connectivity coverage and reduce latency compared with conventional Wi-Fi setups.

Subscription-Based Connectivity Model

Another advantage of the private 5G approach is its alignment with the operational expenditure (OPEX) business model.

Instead of investing large amounts of capital upfront to build complex networking infrastructure, companies can subscribe to a managed service.

The subscription typically includes centralized monitoring, telemetry data and ongoing support.

This model allows companies to scale their robotic operations without making large hardware investments.

For warehouse operators expanding automation, this flexibility can make it easier to deploy new robots and upgrade infrastructure as technology evolves.

The Future of Smart Warehouses

Automation is transforming modern warehouses into highly intelligent environments powered by artificial intelligence, robotics and connected sensors.

These technologies are improving operational efficiency, reducing errors and enabling faster order fulfillment. In many cases, automation systems can increase warehouse productivity by up to 30% while improving inventory accuracy.

However, the success of these systems depends heavily on reliable wireless communication.

As the number of robots in warehouses continues to grow, networking technologies such as private 5G may play an increasingly important role in supporting large-scale automation.

By providing stable connectivity, lower latency and simplified infrastructure deployment, private cellular networks could become a key foundation for the next generation of smart warehouses.
