Picotechnologies have strongly impacted detection, imaging, and communication enhancements such as new transistor and processor architectures. The far-reaching diversity of electromagnetic characteristics and applications, classical and quantum a like, is enticing for rapidly establishing computing and communications domains. Innovation in hardware and software must occur to fulfill evolving speed and memory demands. The process of growth on all-optical components, photonic chips, interconnects, and processing firms will introduce light speed, photon coherence, area isolation and enhancement, information-carrying capacity, and wide spectrum into computing with high performance, the internet of things, cloud, fog, and edge computing markets. Future wireless network applications that blend IoT, intelligent edges, and connectivity will assist all industries, including e-health and medical IoT. Internet of Things (IoT) is a young field of research, but it has enormous potential in medicine and healthcare. IoT is employed for various tasks, such as sensor utilization, machine-to-machine communication, etc., but it is behind in the medical field. It encompasses medical IoT applications, sensors, devices, data visualization tools, and AI. Sixth-generation (6G) cellular network technology employs cells to construct ultra-dense networks (UDN) to address increasing capacity and coverage demands. It predicts that only future 6G networks can offer a high-performance connection with numerous connected devices in challenging scenarios such as diverse mobility, energetic environments, and extreme density.
