During pandemic times, physical contact needs to be avoided and maintaining social distance is essential. IoT based healthcare systems can be considered for the control of pandemics similar to Covid-19, in the future. For the extensive use of IoT focused healthcare, 5G wireless communication systems are used all over the world. In many advanced countries such as China, USA, and South Korea, 5G is already deployed in some cities, and it is in the implementation stage in countries such as India. An IoT based system using artificial intelligence (AI) can control a pandemic to a large extent. It can help to prevent the spread of Covid-19 in the following ways [1, 2]: Secure public safety systems using computer vision technology, Drone usage for delivery of items and sanitization, Tracing people with smartphone-based apps using GPS location, Limiting use of public transport using artificial intelligence empowered platforms. With the IoT, patients who are suffering from diseases such Parkinson's, and Alzheimer's can be monitored from remote areas [3]. It aids patients who are alone DOI: 10.1201/9781003368311-2 5G Wireless Communication System in Healthcare Informatics and who need immediate help [4]. IoT based healthcare solutions manage hospital equipment, patients in a timely fashion, and help to avoid emergency situations [5]. For example, glucose levels can be monitored continuously for a diabetic patient using the IoT from a remote location [6]. Vedaei et al. [1], explain that researchers have developed an IoT framework for the measurement of body temperature, blood oxygen saturation level, heart rate, and for the observation of coughing patterns of patients. Moreover, patients can be tracked by GPS location devices. Further, the collected data can be
