 offers speeds in excess of 100 megabits/second, more data bandwidth, and less latency. This new 5G era integrates more networks, cloud-based storage, and a variety of linked devices and services. Extensive computing capabilities and virtual system architectures allow smart healthcare systems to open the Mobile Internet of Things (MIoT) [25]. Advanced digital networks integrate frameworks that connect billions of devices and sensors to drive advances in healthcare, education, resource management, transpor- tation, agriculture, and many other areas. Much smart healthcare is underway today, but by soon it is expected to make great strides. Korean mobile operators can provide Internet services at super high speeds of 20 GB per second [36]. Other developed countries plan to offer 5G commercial networks by as early as possible. Most parts of the world are connected 24 hours a day, 7 days a week, and the number of digital devices is expected to grow dramatically. In the near future, consumers and businesses will establish a more immersive relationship with digital devices, which will enable them to receive quality medical care in real time at an affordable price. In the 5G world, distributed and independent computing devices will disappear, but real-time healthcare services will become the norm. This allows patients to get closer to the concept of digital fusion in science fiction than ever before. 5G Wireless Communication System in Healthcare Informatics 5G is more than just an extension of 3G and 4G. On the contrary, heterogeneous networks that combine 4G, Wi-Fi, millimeter-wave and other wireless communica- tion technologies are a transformative ecosystem. It combines cloud infrastructure, virtualized network cores, intelligent edge services, and derived distributed com- puting models with insights derived from data generated by billions of devices. 5G transforms the user-centered world into using large machine communications, transforming networks from enabling millions of devices into billions of connected device
