supporting the evolution of the established prominent mobile broadband use cases, NGMN identified the need for 5G to support countless emerging use cases with a high variety of performance attributes and support for a wide range of devices. Studies on various representative use cases resulted in the following families of use cases: Broadband access in dense areas. Improve service availability in densely populated areas, including pervasive video, smart office, operator cloud services, and HD video/photo sharing at stadiums/open-air gatherings. Broadband access everywhere. Provide consistent user experience in terms of throughput, and digital inclusion of people from all geographies, to realize 50+ Mbps everywhere, and ultra-low-cost networks. Higher user mobility. Support the growing demand for mobile services, such as enter- tainment, Internet access, and remote computing, in vehicles, trains, and aircrafts, including moving hot spot scenarios such as walking/cycling demos. Massive Internet of Things (IoT). Support massive number of devices (e.g., sensors, actuators, and cameras) from low-cost/long-range/low-power to broadband machine type communications (MTC), including smart wearables (clothes), sensor networks, and mobile video surveillance. Extreme real-time communications. Support services that require extreme real-time interaction, including safety support for autonomous driving vehicles, remote com- puting, and tactile Internet. Lifeline communication. Realize high levels of availability and resilience to support enhanced public safety and emergency services, even in cases of traffic surge, as well as efficient network recovery in case of natural disasters. Ultra-reliable communications. Support various applications of industries that require very high reliability, such as remote operation and control of machines, collaborative robots, remote surgery, and life-critical services. Broadcast-like services. Support efficient distribution of information from one source to many destinations with possible feedba
