Technological trends in 5G networks for IoT-enabled smart healthcare: A review

Smart healthcare is in the process of quick evolution from the traditional focused approach towards the specialist and the hospital to a patient-centric model. The following technological advancements have boosted this quick revolution of healthcare vertical. Presently, 4G as well as other communication standards like WLAN are applied in healthcare to offer smart healthcare services and solutions. The considers apply for the advancement of further smart healthcare  services in the future. It is for this reason that as the healthcare  industry expands, several applications are anticipated to generate a huge volume of data in various forms and sizes. Thus, the enormous and varying data requires a special approach towards the end-to-end delay, bandwidth, latency and other factors. Thus, it becomes highly challenging for current technologies in communication to effectively support complex and sensitive health care applications in the future. Thus, these 5G networks are being planned and implemented to address the multifaceted requirements of the healthcare  applications for IoT. 5G assisted smart healthcare  networks consist of IoT devices which need better network performance and extended cellular connections. There are issues with existing connectivity solutions namely how many IoT devices can be connected, achieving global standardization, optimizing for low power budgets, how many devices to fit into a given area and secure communication. This paper aims to provide an elaborate review of the smart healthcare solutions in IoT assisted by the 5G technology.
