First, 2G, 3G, and 4G were predominantly about connecting people: they enabled persons to call one another or access the Internet from virtually anywhere, anytime. 5G, with its capabilities for Ultra Reliable Low Latency Communication (URLLC) connec- tivity, has been designed from the outset for high-performance IoT. 5G will enable operators to help their corporate customers automate their business processes. It is worth noting that productivity improvements in physical business processes, such as manufacturing, construction, and logistics, have been lagging service industries, which have been able to digitalize and automate their processes during the last decades. Hence, industry verticals have shown great interest in 5G and plan to build their own private dedicated wireless network, or use operator spectrum and network with slicing technology. Second, we are seeing an interesting conjunction of the three inflection points: 5G as the new radio standard, proliferation of the cloud concept in wireless networks, and rapidly increasing use of artificial intelligence and machine learning. Hyper-successes often occur in business when several major inflection points coincide. An example of an earlier success was 2G Global System for Mobile Communications (GSM): the first ever global standard for mobile communication, with deregulation of telecommunications and the reduction in the price of electronics components making mobile telephony accessible to the masses.
