Book excerpt: 5G technology is a catalyst that will transform many aspects in the design and development of intelligent manufacturing. This book first traces the history and development of manufacturing, landmarked by four industrial revolutions before focusing on the characteristics, product performance, key technologies, and network requirements of intelligent manufacturing. More intelligent, flexible, service-oriented and high-end manufacturing industry is made possible and underpinned by 5G technology. Nevertheless, the introduction to 5G also brings new consideration in terms of data, platform, network, and security. Finally, to illustrate 5G technology in real life, the book presents industrial AR/VR application, cloud industrial robot, full cycle customized production, intelligent resource allocation, upstream and downstream collaborative design, etc.
