ll makes it much more than just another "G" in the succession of wireless technologies-will be directly enabled, empowered, and enhanced by the new NFV- and SDN-based architecture. 11.5.2 5G WIRELESS As wireless technology moved from 2G to 3G to 4G, each generation was "faster and better" than the last, bringing significantly higher speeds and capacities, along with lower costs per bit. 5G will continue this trend and reach higher speeds and capacities, a feature of 5G known as enhanced mobile broadband (eMBB). But 5G will also break from this trend. The same 5G network that offers faster and better will simultaneously offer "slower and longer," by enabling a vastly larger number of inexpensive ubiquitous devices with low data rates and volumes and very long battery lives, as a part of the Internet of things (IoT). This is a feature of 5G known as massive machine type commu- nication (massive MTC). The same 5G network will also simultaneously offer "surer and quicker" services with ultrahigh reliability and ultra-low delays, also known as critical machine type com- munication (critical MTC). This is what makes 5G more than just another G: it does not expand in one dimension; it expands simultaneously in multiple dimensions, offering a wider range of services on a single network. Figure 11.16 illustrates how 5G expands the dynamic range of wireless technol- ogy simultaneously in these three different directions. As a result of these additional capabilities, 5G will enable many new classes of applications such as high-quality augmented reality, the IoT, autonomous vehicles, and industrial automation. Data rate Capacity Connection Latency & Density Reliability FIGURE 11.16 5G expands 4G capabilities in multiple dimensions. Network Access All of these capabilities, and new combinations of these capabilities, will be supported on a single network. This not only brings about economies of scale, but also opens up new avenues for growth and supports increased revenue for network operators. Different classes of applicatio
