Automated guided vehicles (AGVs) are the backbone of modern material handling and manufacturing. Case in point: More than 60% of automotive setups count on AGVs, and 80% of e-commerce sites use them in fulfillment workflows, according to United Robotics Group.
While AGV clients help plants and warehouses move materials and staff operations more efficiently, keeping the machines connected is a constant challenge.
AGVs circulate between production lines, cells, buildings and outdoor yards to keep work moving. As they do, they jump back and forth between wired and wireless networks. Wireless keeps the vehicles linked to telemetry, commands and safety data as they travel; the wired network provides the backbone that links the controllers, safety systems, applications and docking points that AGVs depend on.
Why it’s hard to see what causes AGV stoppages
When AGV problems arise, troubleshooting starts immediately.
But uncovering the real issue is difficult when wired and wireless network management is fragmented. Teams don’t have the control and visibility they need to troubleshoot, identify and prevent AGV connectivity issues.
- Is a switch down?
- Is an access point overloaded?
- Did a security policy change somewhere along the path?
- Is the AGV itself experiencing a fault?
AGV performance depends on having a unified way to manage and control wired and wireless networks.
Why fragmented wired and wireless network management can’t support AGVs
In most warehouses and manufacturing facilities, wired and wireless networks evolve separately as different teams add capacity, deploy applications and attempt to resolve their own issues. No single group has an end‑to‑end view or centralized control.
The approach works well enough when assets are fixed, but it becomes a liability when AGVs enter the picture. Why? Because an AGV’s connectivity path isn’t confined to a single location or domain.
Fragmented wired and wireless network management creates AGV challenges:
- No end‑to‑end visibility into AGV connectivity paths because wired infrastructure, wireless coverage and security policies are managed and monitored separately
- Inconsistent security and QoS policies across domains, leading to drops and slowdowns as AGVs roam
- Higher operational overhead, with separate teams and processes involved with planning, configuring and maintaining each part of the network
- Persistent performance issues, with no centralized way to spot patterns or verify that certain fixes are working (or not) over time
Solving these problems requires managing wired and wireless together through one platform.
The advantages of managing wired and wireless networks as one
Instead of managing wired and wireless networks separately, a unified industrial network treats connectivity as one cohesive “fabric” managed from a single platform.
This gives teams a complete view of the AGV’s path, including the wired backbone that links controllers and safety systems, every switch port and wireless access point, and the AGV client. They can also see where a session drops, latency increases or a policy blocks traffic.
Because the centralized platform applies security, QoS and access policies consistently, AGVs don’t come up against unexpected surprises or failures as they roam. These policies follow the AGV as it moves, so the same performance expectations apply whether a client is docked using a wired connection or roaming wirelessly through the site.
A unified approach to network management offers many AGV benefits:
- Faster troubleshooting so issues can be identified and resolved before downtime causes problems
- More predictable AGV performance with fewer unplanned stops to ensure production continuity
- Safer operation of AGVs, with more reliable communication with safety systems and fewer stops in places where humans are working
- The ability to scale deployments without adding more complexity (each added connection is still managed on the same platform)
- Stronger collaboration between IT, OT and safety, so they can work from the same centralized network view to align decisions
Identify weak links in your AGV connectivity paths
To manage AGV connectivity as a single, unified system, you first need to know where wired and wireless connectivity intersects and where problems exist.
Common weak spots include:
- At transitions between wired and wireless connectivity (when AGVs leave charging stations or docking areas)
- At wired touchpoints that handle charging, updates and data offload
- In zones or areas where wireless coverage is weak
- When AGVs cross VLANs, subnets or security zones
- During roaming events between access points
To make these risks visible, map every AGV route and identify touchpoints along the way: the switches they depend on (and when they depend on them), the access points that serve each path segment and the VLANs or security zones they cross.
You’re mapping these to understand what a unified platform must be able to see and control. This exercise should also expose blind spots where wired infrastructure, wireless coverage and security policies don’t support AGVs.
Put unified network management into practice
From there, you can start to bring visibility and control under a single umbrella.
Depending on how your wired and wireless networks are deployed and managed, this can mean many things:
- Consolidating monitoring tools
- Standardizing policies so they apply consistently to wired and wireless segments
- Introducing platforms that present a unified view of the network from backbone to edge
- Automating configuration and policy enforcement so changes are applied across sites and network domains
By moving toward unified network management, you can support existing AGV fleets more effectively and lay the groundwork for larger deployments in the future.
