Despite all the interest, 6G is still a technology that is in development and not yet up and running. Governments are sponsoring research into 6G, though, to catch up. According to current estimates, 6G won’t be available for about eight years.
Although nothing is definite, it has been anticipated that the first commercial deployment will occur in 2028 or 2029, followed by a wider spread sometime after 2030. Research into 6G technology is undertaken in numerous nations.
According to some estimates, China and Japan are considerably more likely than the West to deploy a 6G network. However, it may still take some time before this technology becomes a practical reality.
Advantages of 6G Network?
6G will call for a change in how communication networks are designed. Multiple vital requirements must be reconciled: serve the massively growing traffic and the exploding numbers of devices and markets while also accomplishing the highest possible standards regarding performance, energy efficiency, and robust security, enabling sustainable growth in a trustworthy way.
Here are some of the advantages 6G will provide:
1. Artificial Intelligence And Machine Learning
Over the past ten years, AI/ML techniques, particularly deep learning, have multiplied and are now used in various image categorization and computer vision-related fields, from social networks to security.
With the methods in 5G-Advanced, AI/ML will be introduced to many sections of the network at many layers and functions.
6G will unlock the full potential of these technologies. From scheduling at the cell site with self-optimizing networks to beam-forming optimization in the radio layer, they all use AI/ML to deliver better performance at lower complexity.
2. Spectrum Bands
Spectrum is an essential component of radio communication. Every new mobile generation needs a new pioneer spectrum that aids in maximizing the advantages of cutting-edge technology. It will also be crucial to transition the current mobile communication spectrum from the older technology to the new one.
The new groundbreaking spectrum blocks for 6G are projected to be at low bands between 460 and 694 MHz for extreme coverage and sub-THz for peak data rates surpassing 100 Gbps, and mid-bands between 7 and 20 GHz for urban outdoor cells providing greater capacity through extreme MIMO.
3. Sensing Network
The most notable characteristic of 6G would be its capacity to detect things, people, and the surrounding environment. By collecting signals reflecting off objects and identifying their type, shape, relative location, velocity, and possibly even material qualities, the network transforms into a source of situational information.
In combination with other sensing techniques, such a form of sensing can assist in building a “mirror” or digital counterpart of the physical world, extending our sensations to every point the network touches.
Combining this data with AI/ML will make the network more intelligent and offer fresh perspectives from the physical world.
4. Exceptional Connectivity
To meet the needs for extreme connectivity, including sub-millisecond latency, the Ultra-Reliable Low-Latency Communication (URLLC) service, which debuted with 5G, will be improved and refined in 6G. Network stability may be improved through simultaneous transmission, multiple wireless hops, device-to-device connections, and AI/ML.
The experience of real-time video communications, holographic experiences, or even digital twin models updated in real-time through the deployment of video sensors will be improved by improved mobile broadband coupled with decreased latency and excellent reliability.
For example, a body or automobile area network can have hundreds of sensors spread across an area less than 100 meters in size. For the machine system to operate, these sensors must communicate within 100 microseconds and be highly reliable.
5. State-of-the-art Security
