6G is a sixth-generation telecommunications standard that is presently being developed for wireless communications technologies that support cellular data networks. The ongoing deployment of 5G technology has urged researchers to explore what occurs next. From 2030 onward, 6G is a prospective communication technology that will enable wireless healthcare to become a reality. The current trend in the smart healthcare system has obstacles like risk of failure, security, and privacy. Healthcare will be absolutely AI-driven and reliant on 6G connectivity technologies, transforming our lifestyle perceptions. In order to have access, creative solutions must be introduced to improve our way of life including intelligent wearable devices, hospital-to-home services, intelligent internet of medical thing, quality of life (QoL), and new business strategy. The proposed intelligent healthcare system is classified into three major modules: hospital atmosphere, remote medical care, and disaster retaliation.
TopIntroduction
The latest 5G (Fifth Generation) wireless communication technology is being consistent and brought into play from 2020 across the globe. The 5G technology was framed with a new architecture design contributing three major communication scenarios eMBB (enhanced mobile broadband), mMTC (massive machine-type communications), uRLLC (ultra-reliable and low latency communications even though, 5G transmission communication will not encounter all the requirements in the future of 2030to satisfy the future requirements there is a need to move beyond 5G wireless communication technology. To satisfy the requirements like higher data rate and ultra-high-speed communication. The current implementation of 5G is expanded and upgraded which leads to the development of new 6G (Sixth Generation) wireless communication technology which is an obvious revolution from 2030 onwards.
In day-to-day life the society and organizations are generating a large amount of data, this phenomenon trends to the next decade and revolution of technology which should support intelligence and automation with an excess of new applications and different challenges towards 6G technology.6G technology’s primary goal is with the evolution of Virtual Reality (VR) and Mixed Reality (MR) Services in the future. In 6G wireless communication technology, the desirable future events in 5G technology such as high data rate, connection density, communication reliability, area traffic capacity, end-to-end delay, spectrum and energy efficiency, etc. are the key performance indicators (KPIs) to enhance the performance of 5G technology. The pre-eminent role of newly generated KPIs in 6G wireless communication technology is to support Distributed Artificial Intelligence (DAI).
As discussed in Akyildiz, I. F., Kak, A., &Nie, S (2020)., the following KPIs function are the basic metrics to evaluate the system performance.
System Reliability
This category of KPIs is now mostly concerned with measurements of system throughput. Peak rate, experienced knowledge rate, peak spectral potency, experienced spectral efficiency, most channel bandwidth, space traffic capacity, and affiliation density are some of the phrases utilized. The experienced data rate and spectral efficiency measurements view the metric that should be certain to 95 percent of user locations in this factor.
System Response Time
Along with delay interference, it includes the end-to-end latency statistic. Jitter may be a new KPI for 6G that measures latency fluctuations inside the system that is not present in 5G.
System Management
They usually deal with network management and orchestration criteria such as energy efficiency, dependability, and mobility. We should note that whereas 5G does not identify a target KPI for the energy efficiency indicator, 6G does, with a target of one Tb/J.
We establish the following essential thrusts in particular:
New Radio Style Paradigms and Spectrum Usage
The need for higher knowledge rates and hence wider channel bandwidths will drive the introduction of rate (THz) and sub-THz spectrum into 6G, as 5G ensures the adoption of mmWave spectrum. At the same time, the introduction of additional spectrum bands will necessitate new radio modes capable of sensing and communicating throughout the entire electromagnetic spectrum.
Innovative Network Architectures
The conventional cell-based wireless network design is incapable of meeting the world traffic capacity and affiliation density requirements imposed by 6G. Instead, 6G will integrate communication infrastructure into the environment’s natural materials.
Increasing Intelligence and Automation
Because of strict channel capacity, stability, and delay requirements of 6G, physical network configuration is unfeasible. Rather, network intelligence and automation will take centre stage, assisting in the development of a more autonomous network.
