The emergence of new technology is making enormous changes in healthcare which is the largest industry in the world. Therefore, a smart healthcare system is required that can communicate across different available network devices and applications. This will enable patients and doctors to trace, observe and record sensitive patient data with medical readings. The Internet of things (IoT) has a great contribution to put the healthcare sector in its leading state to provide the safe and healthy environment for patients and to enable doctors to give outstanding care remotely. The integration of 5G and IoT can be utilized to address these issues due to its capability to handle massive amounts of data with low latency and offers larger bandwidth, fast data rates, and greater reliability. It has heightened the patient involvement and satisfaction due to its capability to make the real time uncomplicated and competent communication among patients and doctors. Thus, a comprehensive smart healthcare architecture including 5G is required. This research is presented a literature review on various healthcare architectures and proposed a customized architecture for a 5G-IoT based smart healthcare system that incorporate different sensors, technology standards and communication protocols. The proposed architecture is validated using a software called Cisco Packet tracer, demonstrating the effectiveness and dependability of the suggested system.
