After years of pilots, private 5G is starting to show up in plants, ports, and warehouses with cases that actually work. What changed in 2025, which deployments make sense, and where WiFi 6E or a wired network still win the comparison.
Industrial edge computing moves processing capacity from the centralised cloud to the plant floor, the machine, or the robotic cell. Local latency (10-50 ms) is critical for process control, machine vision, and safety systems: it is a physical limit that bandwidth alone cannot solve. OPC UA, K3s, and private 5G now form a proven production-ready stack.
Private 5G networks deliver high capacity, low latency, and thousands of connected devices for factories that do not want to depend on a carrier or settle for Wi-Fi. They make sense in large campuses with mobility or high IoT density; for medium plants with fewer than 50 devices, Wi-Fi 6/7 remains more cost-effective.
