6G technology is under R&D phase and many aspects are yet to be defined/ implemented / legalized. Researchers have also been investigating the potential of terahertz waves — microscopic, submillimetre radio waves that exist on the boundary between microwaves and infrared radiation. This will help telecom operators to drastically reduce latency and boost data speeds to as high as 1 tbps.
6G technology is under R&D phase and many aspects are yet to be defined/ implemented / legalized. Researchers have also been investigating the potential of terahertz waves — microscopic, submillimetre radio waves that exist on the boundary between microwaves and infrared radiation. This will help telecom operators to drastically reduce latency and boost data speeds to as high as 1 tbps. 6G technology networks will be able to use higher frequencies than 5G networks, Higher frequencies allow for more data to be transmitted at once resulting in significantly higher capacity and lower latency.
One of the goals of the 6G is to provide internet that supports communications with a latency of one microsecond. This is 1,000 times faster than one-millisecond throughput (or 1/1000th the latency). 6G technology is expected to enable significant advancements in presence technology, imaging, and location awareness. The 6G computational infrastructure, in collaboration with artificial intelligence (AI), will be able to determine the best location for computing to occur, including decisions about data storage, processing, and sharing.
6G has the potential to change the way the human and digital worlds interact. 6G is expected to support virtual reality (VR), augmented reality (AR), metaverse, and AI by 2030. 6G will provide omnipresent wireless intelligence. The 6G research journey is already well underway, with the technology expected to be available commercially early in the 2030s.
What Are The Benefits Or Advantages Of 6G Over 5G?
The higher frequencies of 6G will allow for much faster sampling rates than 5G. They will also have significantly higher throughput and data rates. The use of sub-mm waves (wavelengths less than one millimetre) and frequency selectivity to evaluate the relative electromagnetic absorption rates is expected to advance wireless sensing technology development. Mobile edge computing will be built into all 6G networks, but existing 5G networks will need to be upgraded. By the time 6G networks are deployed, core and edge computing will be more integrated as part of a computation infrastructure framework and combined communications. As 6G technology becomes operational, it could provide numerous benefits. These advantages include improved access to AI capabilities as well as support for advanced mobile devices and systems.
6G is intended to support a greater number of mobile connections than the 5G capacity, which is approximately 10 x 105 per Km2.
6G will transform the healthcare industry by eliminating time and space barriers through guaranteed healthcare workflow optimizations and remote surgery.
Cellular networks have been facing efficiency issues for indoor coverage as the majority of mobile traffic is generated indoors. 6G overcomes these obstacles using femtocells or Distributed Antenna Systems (DASs).
THz frequencies will be used in 6G, which has several advantages. THz waves absorb moisture in the air easily, making them useful for high-speed, short-range wireless communications.
THz provides a narrow beam and better directivity, resulting in secure communication due to its strong anti-interference capability. THz waves can be utilized for space communication to enable lossless transmission between satellites.
6G wireless employs visible lights, which take advantage of LED such as illumination and high-speed data communication
Visible Light Communication (VLCs) does not emit electromagnetic radiation. As a result, it is not susceptible to external EM interference. VLC also contributes to network security.
Additional components, such as the Physical (PHY) layer and Medium Access Control (MAC) layer, will be virtualized in 6G. PHY/MAC implementations currently necessitate dedicated hardware implementations.
Major Challenges Of 6G Wireless
As the technology is still under development, we cannot draw any specific conclusions about the benefits/drawbacks/challenges of 6G until we have a 6G system in place for trial and testing. Some of the expected challenges we come across are listed below:
With a new network architecture 6G employs a cell-free architecture and multi-connectivity. As a result, perfect scheduling is required for seamless mobility and integration of various types of frequencies (THz, VLC, mm wave, sub-6GHz).
Ultra-large-scale antennas are a significant challenge in THz, where high bandwidth and massive quantitative high resolution are required. Processing power is a significant challenge in designing low-power, low-cost 6G devices.
Because 6G wireless technology uses visible light frequencies for some of its communications, the drawbacks of VLC can also be considered drawbacks of 6G wireless technology. Visible light has a wavelength range of 390–700 nm.
A 6G system is required to manage many terminals and networking equipment in a more energy-efficient manner. This necessitates the design of the network and terminal equipment circuitry as well as the communication protocol stack. To meet this demand, energy harvesting strategies are being implemented.

Key Use Cases Of 6G In The Future
The digitalized and programmable physical world: Every physical object, including intelligent machines, humans, and their surroundings, will have a digital representation in the future, and the physical world will be fully programmable and automated. Individually and collectively, the digital representations will manage and process data for prediction and planning in relation to the physical world. Through orchestration, actuation, and reprogramming, the generated insights will have an impact on the physical world.
Internet of senses: The IoTs allows to mix multisensory digital experiences with surroundings and interact with devices, people, and robots as if they were nearby. Visual, haptic, audio, olfactory (smell), and gustatory (taste) sensing and actuation technologies are critical components for realizing digital sensory experiences similar to those experienced in the physical world.
Connected intelligent machines: Intelligent machines that are connected are physical objects and software agents that operate and perform tasks in both the physical and digital realms. In collaborative and aggregate structures, they are linked to applications, users, and each other. As collaborative capabilities advance, the demand for communication capacity and functional capabilities grows exponentially, resulting in new digital and diverse interaction patterns. Furthermore, connected intelligent machines will become increasingly reliant on awareness of both their physical and digital contexts.
6G networks will be extremely complex, necessitating increased deployment time, cost, and management effort. Mobile network operators, on the other hand, expect these networks to be intelligent, self-organizing, and cost-effective in order to reduce operating costs (OPEX). ML and AI are providing pragmatic solutions to many of these challenges, with the potential to completely change the future of wireless network technologies.
