The First 5G-A Factory in Hubei’s Automotive Industry Features a Super Brain.

5G-A, short for 5G-Advanced, can be understood as an enhanced version of 5G, serving as an intermediate step in the transition from 5G to 6G. With faster speeds, greater stability, and enhanced capabilities, 5G-A has already demonstrated its value in areas like smart city construction and vehicle networking.

In such a large warehouse, all handling tasks are performed by just four “robot employees”—AGVs (Automated Guided Vehicles). Their human colleagues, with their hands freed, are only responsible for on-site management and monitoring.

When two vehicles meet, they automatically yield; they locate shelves with precision and autonomously complete picking and placing tasks; they effortlessly lift hundred-kilogram cargo boxes to a height of 4 meters… Why are these little carts so smart?

In the past, AGVs relied on onboard sensors like LiDAR and cameras to perceive their surroundings and navigate using fixed markers like magnetic strips or QR codes pre-installed in the warehouse. Consequently, they could only follow fixed routes. Deployment was troublesome, and changing routes was equally cumbersome.

Now, 5G-A acts as the AGVs’ “cloud super-brain.” The AGVs stream high-definition video from the site to the cloud in real-time. After the cloud brain calculates the optimal route, it transmits the instructions back within milliseconds. When encountering a temporary obstacle, the 5G-A network can complete new path planning within 20 milliseconds, ensuring the AGV’s transport doesn’t stall and its route doesn’t deviate. Even when multiple vehicles operate together, they are guaranteed to avoid collisions.

“These four vehicles can save over a million yuan in costs annually,” explained a technical lead from the planning and logistics department. The AGVs enable on-demand, precise material delivery, unaffected by time or operator skill, operating 24/7 without interruption. Warehouse operational efficiency has increased by over 40% compared to before.

AGVs need to transport goods back and forth, but how do they know where the goods are? On the cargo boxes on the warehouse shelves, there is a label slightly larger than a band-aid. Peeling back the label reveals its secret—an antenna and chip are hidden on the back.

These labels, costing as little as a few dimes, are the “nerve endings” of smart warehousing. They utilize the latest passive IoT technology. “Passive IoT means ‘power-free’ Internet of Things; they operate entirely on ‘borrowed’ energy,” explained a deputy team leader from a 5G IoT project group.

It turns out the warehouse is equipped with numerous 5G-A base stations about the size of a biscuit tin. When these passive tags enter the electromagnetic wave coverage area of a 5G-A base station, their built-in antennas capture these waves. The chip then converts the captured electromagnetic energy into its own power. Once activated, the tag immediately “reflects” its location information back to the warehouse management platform. Even with thousands of tags working simultaneously, anti-collision algorithms prevent chaos.

Leveraging this technology, thousands of pallets, cargo boxes, and tools within the factory are transformed into perceptible, traceable, and interactive smart nodes. Goods with these tags enable unmanned, automated inventory management and precise positioning… Coupled with the efficient data backhaul of the 5G-A network, this enables fully digitalized process
