1. What's exactly 6G?

6G (sixth-generation wireless) is the successor to 5G cellular technology. 6G networks will be able to use higher frequencies than 5G networks and provide substantially higher capacity and much lower latency. One of the goals of the 6G internet is to support one microsecond latency communications. This is 1,000 times faster -- or 1/1000th the latency -- than one millisecond throughput.

The 6G technology market is expected to facilitate large improvements in the areas of imaging, presence technology and location awareness. Working in conjunction with artificial intelligence (AI), the 6G computational infrastructure will be able to identify the best place for computing to occur; this includes decisions about data storage, processing and sharing.

It is important to note that 6G is not yet a functioning technology. While some vendors are investing in the next-generation wireless standard, industry specifications for 6G-enabled network products remain years away.

2. Why 6G is gaining importance?
The next-gen tech (6G) will likely be 100 times faster than 5G. The benefits go far beyond speed, however. 6G will be a fully integrated system that allows for instantaneous communications between devices, consumers, and the surrounding environment. 6G-enabled enterprise technologies will transform the way companies process information, communicate, make decisions, and train employees.

3. What's the features of 6G?
6G networks may coexist with 5G for a while and will be a significant improvement over previous generations in several ways. This is because 6G will offer the following differentiated features:

1. The use of new spectrum bands

2. Very high data transfer speeds

3. Ultra-low latency network functions

4. Greater support for machine-to-machine (M2M) connections

5. A focus on energy efficiency

6. Greater network reliability

7. The rise of new architectures

8. The use of AI and ML for optimal connectivity

Communication technology of the sixth generation will decrease user-experienced latency to less than 0.1 milliseconds. Numerous delay-sensitive real-time applications will have better performance and functionality due to this drastic reduction in latency.

Additionally, decreased latency will allow emergency response, remote surgical procedures, and industrial automation. Furthermore, 6G will facilitate the seamless execution of delay-sensitive real-time applications by making the network 100 times more dependable than 5G networks

4. How 6G will work?

The exact working of 6G is not yet known, as the specification is yet to be fully developed, finalized, and released by the ITU. However, depending on previous generations of cellular networks, one can expect several core functionalities. Primarily, 6G will operate by:

  • Making use of free spectrum: A significant portion of 6G research focuses on transmitting data at ultra-high frequencies. Theoretically, 5G can support frequencies up to 100GHz, even though no frequency over 39GHz is currently utilized. For 6G, engineers are attempting to transfer data across waves in the hundreds of gigahertz (GHz) or terahertz (THz) ranges. These waves are minuscule and fragile, yet there remains a massive quantity of unused spectrum that could allow for astonishing data transfer speeds.
  • Improving the efficiency of the free spectrum: Current wireless technologies permit transmission or reception on a specific frequency at the same time. For two-way communication, users may divide their streams as per frequency (Frequency Division Duplex or FDD) or by defining time periods (Time Division Duplex or TDD). 6G might boost the efficiency of current spectrum delivery using sophisticated mathematics to transmit and receive on the same frequency simultaneously.
  • Taking advantage of mesh networking:Mesh networking has been a popular subject for decades, but 5G networks are still primarily based on a hub-and-spoke architecture. Therefore, end-user devices (phones) link to anchor nodes (cell towers), which connect to a backbone. 6G might use machines as amplifiers for one another’s data, allowing each device to expand coverage in addition to using it.
  • Integrating with the “new IP:” A research paper from the Finnish 6G Flagship initiative at the University of Oulu suggests that 6G may use a new variant of the Internet Protocol (IP). It compares a current IP packet inIPv4 or IPv6to regular snail mail, complete with a labeled envelope and text pages. The “new IP” packet would be comparable to a fast-tracked courier package with navigation and priority information conveyed by a courier service.

6G will rely on the selective use of different frequencies to evaluate absorption and adjust wavelengths appropriately. This technique will leverage the fact that atoms and molecules produce and absorb electromagnetic radiation at certain wavelengths, and the emissions and absorption frequencies of any particular material are identical.

5. What's the components of 6G?
The 6G Vector Component Analysis Solution comprises a 4-port PNA-X network analyzer, test set controller, arbitrary waveform generator, and external up and downconverters.

7. How Phase wise development has taken place in cellular technology?

Before delving into 6G, it’s crucial to appreciate the journey of wireless communication. The first mobile phones, known as 0G, were a marvel simply because they were entirely wireless. 1G brought mobile phones to the masses, and 2G sped up communication, introducing text and picture messages. 3G, significantly faster than 2G, laid the foundation for internet-based apps. 4G took it a step further, enabling streaming and multiplayer gaming.

5G, the current marvel, boasts low latency and enables remote machine control and a seamless browsing experience. However, it faces challenges, such as the need for numerous towers due to the use of easily obstructed millimeter waves. This limitation leads to phones frequently switching between 5G and 4G.

Diving into the 6G network

6G, the sixth generation of cellular technology, is poised to redefine wireless communication. While 5G was a significant step towards the Internet of Things (IoT) and industrial automation, the 6G network seeks to seamlessly integrate the digital, physical, and human realms.

Speed and Beyond

6G is expected to tap into previously unexplored radio frequencies, potentially reaching ultra-high levels of 300 gigahertz or even terahertz. This increase allows for more bandwidth and swifter data transmission. One of 6G’s most ambitious targets is achieving a latency of just one microsecond, a vast improvement over 5G’s one millisecond. Such ultra-low latency will be crucial for real-time applications like virtual reality, AI-driven robotics, and autonomous vehicles.


8. What are the applications of 6G?
 
It is essential to identify key business use cases to stimulate the uptake of new technologies. Despite carriers' touting the superior performance that 5G mmWave provides, the mmWave market has yet to take off despite years of 5G's commercialization. The vast majority of 5G build-outs continue to use 5G sub-6 GHz. The reasons? The one reason that most people mention, according to IDTechEx's primary interviews, is the absence of applications that can be only enabled by mmWave and no other technologies. The same question about 6G will be asked: why is it needed?
 
From a consumer's perspective, having a Tbps data link and microsecond level latency but paying a higher subscription fee will probably not be attractive if the applications on their mobile devices are pretty much the same as what they have right now. We've heard a lot about hypes going on metaverse enabling by 5G and 6G, yet, the real-life use cases that can drive widespread adoption are still lacking. However, it should not be forgotten that 6G will have its unique capability in sensing, imaging, precise positioning, and so on. These characteristics will open other business use cases and enable 6G to be used in areas beyond mobile communication, which can further drive advanced digitalization and automation of various industries. For example, using 6G networks to achieve accurate perception and centimeter-level positioning of mobile robots, demonstrating the ability to remotely control mobile robots to pick up and carry various objects. At the same time, this transmission link also carries the high-speed wireless transmission of real-time high-definition video between the mobile robot and the controller, enabling synaesthesia integration. Furthermore, as the spectrum expands beyond 275 GHz, interesting use cases worth highlighting include the use of THz connections as wireless links to replace fiber for data centers, enabling reconfigurable routes and allowing the reduction of the size of server/router racks, and of course, significant cost reduction; and creating one or multiple point-to-point high-speed communication links within a device, enabling faster routing.
