1、WHITE PAPER Industrial IoT in a 5G world - Architecture WHITE PAPERINDUSTRIAL IOT IN A 5G WORLD - ARCHITECTURE 2 specific IoT applications. In this paper we consider low-rate instrumentation for temperature, pressure, vibration and other telemetry, and also imaging and video monitoring, with require

2、ments ranging from low-resolution video surveillance to very high-speed interactive video for real-time control and augmented reality applications. Traffic requirements include low-to-high data rates and differentiated quality of service treatment including prioritization on shared infrastructure, l

3、atency and jitter. Finally, security is an over-arching requirement that plays a significant role in wireless network technology and design. While many wireless standards target Industrial IoT, including PROFINET, Wireless I/O, ISA100, wirelessHART, LoRa and others, only Wi-Fi and cellular 4G/5G spa

4、n the network scale, traffic capabilities and diverse topologies required for the networks defined above therefore, the paper focuses on these technologies. It categorizes four different network models, one with Wi-Fi and three that use variants of cellular technology. It is important to specify the

5、 deployment model, because while cellular technology and Wi-Fi each have advantages in certain architectures, these advantages are network-architecture-dependent, and are not available in all network models. Wi-Fi networking for Industrial IoT is well-understood from widespread deployments over many

6、 years. Wi- Fi can be deployed anywhere, globally, in unlicensed spectrum, using a wide range of inexpensive devices and infrastructure. Paradoxically, the ubiquity of Wi-Fi has driven misconceptions: enterprise class WLANs have for many years deployed very strong security and quality of service, bu
