kets. In addition, the COVID-19 epidemic may have accelerated this timeline significantly, but it is unlikely that 5G applications such as wearable medical devices and telemedi- cine will be widely accepted by consumers in the coming years. With the increasing need for confidentiality and reliability of medical data, people are beginning to raise concerns about security and privacy as medical records are transmitted over huge, often global public networks [41]. An eco-system that describes 5G integrated smart healthcare with the patient at the center of all activities, services, devices, and products is shown in Figure 4.4. In the situation of the latest COVID-19 pandemic, healthcare industries have paid great attention to the potential of 5G in supporting telemedicine services and computer-based physician consult- ation. This is useful if you need physical distance or if the patient is far away from the medical facility. 5G Wireless Communication System in Healthcare Informatics healthcloud Physician Smart Healthcare 1000.

Existing 4G and fixed broadband infrastructure enables basic one-to-one low- touch conversations. However, 5G has great potential to facilitate these interactions [42]. For example, add sensors and virtual reality to a conference call to allow healthcare staff to monitor remotely vital parameters of a patient once the call is live. In addition, 5G can send large numbers of data packets, SO smart healthcare can use a cloud-connected scanner to test changes in a patient's heart rate, sugar level in blood, and blood pressure, multiple times a day. These advances, in turn, provide more insight into the patient's routine medical care. With the addition of 5G and many other cutting-edge i
