  5G wireless systems will extend mobile communication services beyond mobile
telephony, mobile broadband, and massive machine-type communication into new
application domains, namely the so-called vertical domains including the smart
factory, smart vehicles, smart grid, smart city, etc. Supporting these vertical
domains comes with demanding requirements: high-availability, high-reliability,
low-latency, and in some cases, high-accuracy positioning. In this survey, we
first identify the potential key performance requirements of 5G communication
in support of automation in the vertical domains and highlight the 5G enabling
technologies conceived for meeting these requirements. We then discuss the key
challenges faced both by industry and academia which have to be addressed in
order to support automation in the vertical domains. We also provide a survey
of the related research dedicated to automation in the vertical domains.
Finally, our vision of 6G wireless systems is discussed briefly.
