The potential of 6G technology will become evident because of its intrinsic power to allow immersive smartphone experiences. It opens up multiple opportunities that blur boundaries between physical and online platforms. In other words, 6G technologies will create a collision of material and virtual reality. Work and home will be deeply connected, and people will move freely around for social interaction. According to the latest figures, the global 6G market will accomplish a financial worth of about $1.04 billion in 2028. By 2032, the forecast shows that the industry will reach around $40.99 billion, exhibiting a CAGR of 150.4%.
6G Networks: Lack of Protocols but High Market Potential
Currently, no standards for 6G networks have been created because there is still work to do regarding their power consumption and wireless signal transmission. The U.S. Federal Communications Commission (FCC) has set 95 GHz and 3 THz for initial Research and Development (R&D).
According to the latest research, Finland’s University of Oulu initiated the 6Genesis research project to establish a 6G vision for 2030. The institution has decided to cooperate with Japan’s Beyond 5G Promotion Consortium regarding Finnish 6G Flagship research on 6G networks.
Moreover, South Korea’s Electronics and Telecommunications Research Institute (ETRI) is experimenting with the terahertz frequency band for 6G. In contrast, Samsung plans to invest more than $355 billion into chipset manufacturing to facilitate the progress of 6G architecture.
6G Technologies: A Powerful Cluster of Numerous Networks
Commercialization of 6G technologies is likely a decade away because there is significant work to do. Experts must ponder the technological challenges of delivering higher speed, more storage capacity, and lower latencies than 5G networks.
As 6G networks will trigger the convergence of existing technologies, it will be the network of multiple interfaces. In accordance with Phil Solis, the applications of the 6G network will be beyond marketing because of Orthogonal Frequency-Division Multiple Access (OFDMA) in WiFi 6. It is a technology that supports uplink and downlink communications with several customers with the help of numerous Resource Units (RUs).
As per Paolo Gargini, experts are talking about the hybrid applications of 6G technology, but there is infrastructure transformation required. For instance, there will be a need to install fiber broadband connections to limit the loss of signals during data transmissions at Tera-Hertz (THz) frequencies.
There is another way to improve data transfer rates and control resource consumption. Japan’s telecommunications company NTT’s 6G work comprises the progress and testing of a mobile network that utilizes an end-to-end optical communications architecture called Innovative Optical and Wireless Network (IOWN). The network cluster uses photons for fast data transmissions without transforming data into electrical signals. NTT aims to bring a 100-fold improvement to power use, end-to-end latencies, and transmission capacities compared to traditional approaches.
According to Spirent Douglas, 6G technologies will facilitate the convergence of WiFi and cellular technologies. There can be any software underneath the 6G network, but if there is standardized interoperability, users will have no issues. Nevertheless, the visions for 6G and any standardized approaches are highly likely to transform before their widespread commercial use.
Potential Applications of 6G Technologies
6G networks will transform the world because of their wide applications. According to the experts, its various use cases are below:
In the telecommunication industry, 6G networks will introduce multi-sensory technologies to establish new ways of social connectedness and interact with the environment via all five senses. It means that 6G networks will eradicate physical and time-related limitations through holographic imaging and streamlining human-to-human and human-to-machine connections. Almost all the networks will be AI-driven, facilitating complete digitization.
According to Andreas Roessler, TeraHertz communication (THz), Joint Communication and Sensing (JCAS), AI & ML, Reconfigurable Intelligent Surfaces (RIS), and Visible Light Communication (VLC) are among the type of advancements that will transform the 6G era. JCAS will improve communication via efficient beam management, alignment, and feedback. It will enable new applications — for instance, gesture recognition, vulnerable road user detection, and human-machine interaction.
6G networks will comprise ultra-wideband, low latency, high intelligence, and spatialization. Such factors will facilitate better communication and allow immersive Extended Reality (XR), high-fidelity holograms, and digital replicas without any limitations. Consequently, 6G networks will be constructed while keeping in mind the cloud storage to enable efficient reprogramability.
A powerful motivation behind 6G networks is the upcoming deployment of Connected Robotics and Autonomous Systems (CRAS), including effective drone delivery, self-driving cars, and autonomous robotics. CRAS mandates control system-driven latency requirements and the potential need for Enhanced Mobile Broadband (EMBB) transmissions of High Definition (HD) maps. CRAS is the top-tier use case that requires stringent standards across the latency spectrum; which is absent in 5G.
In accordance with the latest research, identity verification solutions will be extremely important for 6G mesh networking. It implies that the availability of fast data transfers will empower experts to communicate with each other effectively and catch fraud instantly. In this way, it will allow quick local and cross-border communication, enabling law enforcement agencies to conduct efficient criminal investigations.
The need for massive development and intelligent networks are significant factors behind the growth of the Global 6G Market. According to Polese, the arrival of 6G technology will address the issues of 5G networks. The introduction of 6G with higher frequencies for quick data transfers is highly attractive to universities and industries. As per Jornet, there will be enough progress on 6G to make the advancements evident. Thereupon, it will guide further development and finalization of standards.
