-based surveys have shown significant agreement in taking the view that the major pitfall of 5G is the speed of data transfer [16]. The view is often wrongly taken that the role of 5G, and other future improvements is to increase the speed of data transfer. This has resulted in misaligned expectations of this technology, whose only major selling point is to provide lower latency and higher bandwidth than 4G LTE Advanced [18]. Consequently, as these expectations go unchecked, public behavior impacts the 5G service as expectations from the service differ significantly from what the service offers. Many people concurrently access the networks hoping to utilize higher data transfer rates only to be left disappointed [17]. Though it might appear to be a hindrance, it is also considered that this excessive misaligned expectation can actually work in favor of 5G as more devices attempting to be a part of the network would require more connection nodes on a network which in turn causes the network to increase data transfer speeds in order to meet benchmarks of lower latency than 4G [19]. 1.3.3 WHAT Is SMART HEALTHCARE? The concept of smart healthcare came to the fore with the development of informa- tion technology. Healthcare which uses smart technologies such as big data, wear- able devices, IoT, and AI, to name but a few, is described as smart healthcare in the literature. Smart technology is needed in healthcare to make it efficient, convenient, and personalized. With the advancement of information and technology, conventional medicine and the healthcare sector also gradually began to digitize and introduce the concepts of preventive healthcare rather than only focusing on disease treatment. Various features of 5G such as fast data transmission with low latency, large band- width, intelligently make use of physical resources and intelligence at the edges of the network making 5G more popular for smart healthcare. 1.4 APPLICATIONS OF 5G IN HEALTHCARE AND OPEN CHALLENGES Although 5G has various features starting with h
