1 Scope

GB/T 42126.5-2024 sets the application requirements for industrial wireless communication over cellular networks. Private 5G in factories is one of the most heavily promoted industrial technologies in China, and the gap it has to close is real: cellular networks were engineered for human traffic, best-effort and tolerant of variable latency, while a motion control loop or a safety function needs bounded latency and a defined failure behaviour. This part states what the industrial applications actually require, so that a network can be engineered and accepted against it. It covers the classes of industrial application and their characteristics, the requirements each places on latency, jitter, reliability, availability, determinism, data rate, device density and mobility, the requirements on time synchronisation, on positioning where the application needs it, on security and isolation, and on the coexistence with the wired industrial networks and with the existing wireless systems in the plant, together with the verification of those requirements. It takes effect on 1 November 2024.

This document provides the application process of industrial cellular networks and specifies the requirements analysis, design and construction of industrial cellular networks: The requirements of various stages such as industrial cellular network design, industrial cellular network integrated application and industrial cellular network application scenario acceptance: This document is applicable to industrial cellular network providers, integrators, third-party service agencies and industrial users who are engaged in the development of industrial cellular networks: application:
