With the world now starting to look at the future with the next generation of wireless communication technology- 6G, it can only be assured that the world is in the precipice of a technological revolution. Though 5G is yet at the early stage of deployment around the world, the idea of 6G is gradually emerging as the next generation, which is expected to introduce even more enhancements in communications. The future network is expected to offer more enhanced parameters of speed, reliability and coverage than the current one and be very useful for different industries and consumers.
The key technologies which are expected to shape the future of the 6G networks are Reconfigurable Intelligent Surfaces (RIS) and High Altitude Platform Station (HAPS) systems. These are the innovations that will or can revolutionize the implementation of various aspect of information and communication technology especially wireless communications and internet provision to hard to reach and marginalized communities. In this article we will try to understand the importance of such technologies and their implications for the global context.
The Promise of 6G: Innovative Requirements Other Than Speed and Capacity
5G, for instance, has provided great enhancements of data rates and latency, and 6G is expected to extend these improvements. Currently, the plan to bring 6G networks to the public is still at the drawing board and it is expected that these networks are going to be10-100 times faster than the current 5G with a latency of up to 1 microsecond. This implies a continual transfer of data which is crucial for real time operation in areas such as auto mobile industry, telemedicine, and augmented reality among others.
However, it is not simply a matter of time or speed as we’ve previously seen with 5G. It will also relay emphasis on such factors as sustainability, energy and the employment of artificial intelligence in the communication network density. By means of AI, 6G networks will be able to self-optimize as the 5G networks do now, and increase performance based upon analysis of real time data. It will provide a high level of intelligent network management to enrich the users’ experiences, accommodate the high number of machine type communications and provide M2M connection where it is most difficult.
Reconfigurable Intelligent Surfaces (RIS): Some of the concepts that was discussed include: The Future of Wireless Communication
Thus, the Reconfigurable Intelligent Surface (RIS) is emerging as one of the most promising trends in the 6G world. Some of these surfaces can be made from metamaterials which allow them change the characteristic of the electromagnetic field to control the progression of the radio waves. In this way, optimizations can be made to the wireless communications environment to both increase the strength of the signal by focusing it and reduce the amount of interference to the signal and increase the coverage area of the signal.
Once again, one can imagine how the walls, the windows or even the furniture may become the points of communication. It is enough to install RIS which can transform any surface and direct signals to the right area. This capability is especially important in urban areas because the buildings and other constructions interfere with the signals thus resulting in poor coverage and call drops.
Thus, in the practical sense, RIS can truly fashion out ‘smart cities’ with connectivity throughout. For instance, in a crowded populated region / city, the RIS supported structure may guarantee that every part of the city receives a strong and stable wireless signal. It would not only enhance the effectiveness of user service, but also eliminate the necessity of new base stations that would require more energy for their operation thus decreasing the energy consumption of the network.
Further, the target connectivity environment of 5G high-frequency signals is mainly indoors, and RIS can serve as an important help for improving indoor connectivity. When installed inside various structures, there are ways to position the RIS panels to make sure they get that penetration to different areas deep inside structures such as offices, homes and other public places.
High Altitude Platform Station (HAPS) Systems: The title ‘connecting the unconnected
is appropriate for this book because the author seeks to describe how people who have never or hardly interacted with China rapidly become connected with it after engaging in investments in the country.
Although RIS is centered on the improvement of networks that are currently in existence, High Altitude Platform Station (HAPS) systems provide an alernative means of extending the reach. HAPS systems include unmanned aerial vehicles or balloons that HAPS deploys in a system with intended operations in the stratosphere, roughly at 20 kilometers above the surface of the Earth. These platforms can offer coverage over large geographical regions, in areas that it is not feasible to lay down ‘conventional’ cabled infrastructure.
HAPS systems are most suitable in such regions because the absence of structures in such areas has continually been a hindrance to internet connectivity. Thus, the use of HAPS enables internet service providers to provide communities that have been left behind in their current generation with high-speed internet connection. This is important for e-competiveness as well as e-marginalization because the use of access to the internet is now regarded as a human right as well as the most potent tool for development.
Besides, the integration of HAPS systems remains useful in with situation or even disaster response situations. When disasters happen and there is a damage to the land-based systems, HAPS can immediately provide communications services, which will help the emergency agencies tackle issues, while providing help to the affected individuals. They are very useful in crisis situations because of their capability to link large spaces with when little or no delay.
Moreover, HAPS systems can augment the current satellite networks thus, providing more capacity and backup. Satellites are used for coverage over large geographical areas but the disadvantage of satellite links is that the links are usually many kilometres up in the air which leads to high latency as compared to terrestrial networks. Besides, HAPS, flying at a lower altitude than satellites, can offer quicker and more effective communication services which are very useful as an addition to the present satellite covering.
The Road Ahead: Correlating challenges with Opportunities
Despite this, the future of the 6G and all associated technology is very vivid, however there are still a lot of challenges on the way. Such concerns include the ability to establish new standards and policies by which the 6G networks will be deployed. Due to the nature of telecommunication being global, cooperation will be critical to see to it that the 6G implementation is done in a way that is advantageous to all the world’s countries and/or regions.
Another challenge that is associated with 6G is how to connect 6G with the running networks. Since 5G is relatively new, the service providers will have to plan for an upgrade to 6G with a lot of caution to ensure that they integrate the new network in a way that will complement the older generations. Much will need to be devoted to the development of the physical layer for 6G including the hardware and software that is necessary for the higher frequency bands and data rates which are expected with 6G.
The issue of security is also paramount important. The issues become more complex as networks are implemented and become more extensive and interconnected thus the chances of experience a cyber attack are elevated. It will hence be important for the 6G to design security features that would enable the networks to be protected from such threats as well as ensure users’ privacy. This will include solutions as well as the policies that seek to contain the emerging threats in cybersecurity.
However, the problems posed by the evolution to 6G cannot be overlooked since the advantages of this network or communication are evident. With the current era being characterized with rapid adoption of digital technology, the need for faster, reliable and more pervasive networks will continue to rise. 6G and other technologies like RIS and HAPS hold promise in meeting this demand making the world a completely different ball game in terms of living, working, and interacting.
