  5G has been defined to address new use cases beyond consumer-focused mobile
broadband services. In particular industrial use cases, for example in smart
manufacturing, have been addressed in the 5G standardization, so that 5G can
support industrial IoT services and wireless industrial networking. To this
end, 5G needs to integrate with the industrial network based on Ethernet and
TSN. 5G can create new opportunities for smart manufacturing by enabling
flexibility and increasing the automation in the production. This paper
provides an overview of the use cases and requirements for smart manufacturing
that can be addressed with 5G and which are validated in three industrial 5G
trial systems. The capabilities of 5G are described for providing non-public
networks that support industrial LAN services based on Ethernet and TSN. The 5G
radio access network functionality is described and discussed for practical
deployments. The paper provides an overview of the current state-of-the-art of
using 5G for smart manufacturing.
