# Technologies Trend towards 5G Network for Smart Health-Care Using IoT: A Review
## 2 Taxonomy
### Smart Health-Care Requirements  
Smart health-care requirements may be extensively arranged in functional and non-functional necessities, as presented in Figure 3. Technical specifications deal with the particular needs of the health-care design. For example, the temperature supervising system is organised, in the view of application that it is utilised for, the operation range of thermometer/thermistor, mechanism of data collection, and operation frequency might be different. Therefore, functional requirements are particular to vary segment utilised in that smart health-care system in the light of their application.  
On the other side, non-functional specifications are not entirely specific. This requirement implies features through which issues in the health-care framework can be resolved. On a more general point of view, non-functional essentials of health-care may be categorised in ethical and performance specifications. Because of a massive number of barriers being associated with planning an entire intelligent health-care arrangement, performance specifications are additionally characterised in hardware and software specifications. For the smart health-care technique, the basic requirements are system reliability, higher efficiency, small form factor, low power, quality of service, enhanced client encounter, the reputation of the intelligent health-care methodology to provide consistent help, the versatility of method to move up to more up-to-date forms and advances, and abundant availability.

Therefore, the specific prime thought process of design and intelligent health-care is to guarantee health service quickly. For cutting edge applications, alongside these specifications, the structure additionally requires ambient intelligence to enhance the nature of the facility.  
Points of view of smart health-care broadly differ among researcher and ventures with respect to the picked objective to be accomplished. Parts of intelligent health-care technique may be characterised based on the sensors or actuators, processing devices, information storage components, and network components. A sensor is a sensing device that joins with an organic element that recognises events [58]. Sensors or actuators change, depending on the monitoring system. EMG, blood pressure, ECG, temperature sensors, SpO2, accelerometers, orientation sensors, sensors for motion, and heart rate, are the typical sensors utilised in the smart health-care system. Computing devices used varies from PDAs, smartphone, and tablets to complex and advanced devices, for example, super PCs and servers. Storage assumes an essential job in intelligent health-care, because the storage of data is considered to be the most vital component of the systems. Information repository parts in the creative health-care network ensure a more extensive range beginning from implanted memory on the detecting gadgets to massive servers that are utilised to deal with large information analytics. Network components differ from connected sensors to switches and base stations. In light of the seriousness of the smart-health-care solution tended to, the complexity of the modules changes. Wireless technologies are the foundation of the intelligent health-care network. Distinctive types of wireless technologies, for example, Bluetooth, Wi-Fi, RFID, 6 LoWPAN, and so on, as presented in Figure 2, allow for the data to be exchanged among various physical components that are designed to shape the smart health-care network.
