5G Private Network + Industrial Gateway: In-Depth Analysis of Ultra-Low Latency Communication Configuration for AGV Trolleys in Dark Factories
In the wave of intelligent manufacturing, "dark factories" have become a core objective for enterprise transformation and upgrading, thanks to their unmanned, automated, and highly efficient production models. However, as the "logistics arteries" of dark factories, AGV trolleys' communication stability and real-time performance directly impact production efficiency and safety. Traditional Wi-Fi or 4G networks suffer from issues such as high latency, high packet loss rates, and roaming stuttering, causing frequent AGV breakdowns. A certain auto parts factory once experienced an average daily downtime of 47 minutes due to communication failures, resulting in annual losses exceeding RMB 10 million. This article provides an in-depth analysis of the collaborative configuration solution of a 5G private network and the industrial gateway USR-M300, offering enterprises an ultra-low latency, highly reliable AGV communication solution to help build true dark factories.

1.Three Core Pain Points in AGV Communication in Dark Factories
1.1 Conflict Between Real-Time Control Requirements and Network Latency
AGV trolleys need to respond to control commands within milliseconds to complete actions such as obstacle avoidance, path planning, and emergency stops. Traditional Wi-Fi networks typically have latencies above 50ms, and while 4G networks can reduce latency to 20ms, they still fail to meet the demands of complex scenarios. Data from an intelligent workshop of a textile enterprise shows that when network latency exceeds 5ms, the AGV obstacle avoidance failure rate increases to 12%, directly threatening production safety.
1.2 Challenges of Mobile Roaming and Signal Coverage
AGV trolleys need to frequently switch wireless access points (APs) when moving across regions. In traditional solutions, roaming handover delays can exceed 100ms, causing data transmission interruptions. Actual measurements at a logistics center show that roaming stuttering reduces AGV transportation efficiency by 30%. Additionally, obstacles such as metal shelves and large equipment easily create signal blind spots, further exacerbating communication instability.
1.3 Concerns Over Data Security and Privacy Protection
The data transmitted by AGV trolleys includes sensitive information such as production formulas, equipment status, and process parameters. Traditional public network transmissions require passing through third-party cloud platforms, posing risks of data leakage. A chemical enterprise once experienced formula leakage due to unencrypted transmission of production parameters, resulting in direct losses exceeding RMB 10 million.
2.5G Private Network: The Core Engine for Solving AGV Communication Challenges
2.1 Technical Advantages of 5G Private Networks
Through a "private network for exclusive use" model, 5G private networks provide customized network services for enterprises, with core advantages including:
Ultra-low latency: End-to-end latency can be compressed to within 1ms, a 90% reduction compared to 4G, meeting the real-time control requirements of AGVs.
High reliability: Network slicing technology reserves dedicated spectrum resources for AGV services, ensuring zero packet loss for critical data transmission.
Large bandwidth: Supports transmission rates of 1-10Gbps, enabling real-time backhaul of multimodal data such as lidar and 4K cameras.
High-precision positioning: Combines 5G base station positioning with GNSS technology to achieve centimeter-level positioning accuracy, optimizing AGV path planning.
2.2 Selection of Deployment Modes for 5G Private Networks
Enterprises can choose from the following three deployment modes based on their needs:
Standalone (SA): Build a core network and base stations independently, achieving complete physical isolation, but with high deployment costs, suitable for large enterprises.
Non-Standalone (NSA): Share the operator's core network while building base stations and edge computing nodes independently, balancing cost and performance.
Virtual private network (slicing): Based on the operator's public network slicing, allocate dedicated QoS for AGV services, with the lowest cost, suitable for small and medium-sized enterprises.
Case Study: Robam Appliances' "dark factory" adopted China Mobile's 5G SA standalone networking mode, reducing latency to within 2ms through "5G factory slicing technology," enabling real-time monitoring and scheduling of 16 production lines and 32 loading and unloading points, with data stability improved by 100% compared to Wi-Fi.
