6G Technology: Reshaping the World with the Networks of the Future [EN]
The Future of Technology: What is 6G and What Does It Promise?
Imagine a world where machines are controlled by the mind, driverless cars navigate heavy traffic without accidents, and the internet is a thousand times faster than today. This is the promise of 6G! While 5G has enabled unprecedented speeds and applications, technological advancement never stops, and now we are entering a new era: 6G. Behind this seemingly predictable name lies a technology that could revolutionize the world. But what exactly is 6G?
The Foundations of 6G Technology
Our daily lives are surrounded by an invisible network of data coming from smartphones, TVs, sensors, and other smart technologies. However, previous versions of this network (like 4G) lacked the bandwidth to send complex data. This is changing with 6G. 6G will enable data transmission at ultra-high frequencies. While 5G supports frequencies up to 100 gigahertz (GHz), 6G aims to use technologies like terahertz (THz) waves to transfer data at frequencies ranging from hundreds of gigahertz to terahertz.
A One-Microsecond Latency
Another goal of 6G is to support “one-microsecond latency.” Latency is the delay in the transmission of information from one place to another. 6G will operate with a latency of one microsecond, which is a millionth of a second, meaning near-instantaneous data transfer. This capability opens the door to a new era of possibilities. Significant progress has been made in areas like artificial intelligence, smart sensors, and virtual reality, but these still largely operate separately. 6G will virtually connect all these technologies.
Edge Computing and Smart Sensors
Another technology that 6G will support is edge computing. Until now, most smart technologies have relied on a central processor operating in the virtual cloud. For instance, sensors on roads send traffic or weather data wirelessly to the cloud for a system to process. However, edge computing means these sensors will be smart enough to process data locally without sending it to a central cloud. This will make everything faster and reduce the risk of signal interruptions in critical systems like driverless cars.
A New Era in the Digital World
6G could create a true digital world where your physical presence can work virtually. You could work in a virtual office with digital representations of your colleagues or study at a distant school. 6G will enable virtual interactions with objects because it can transmit the large amounts of data needed to simulate things like touch and sensation very quickly. Companies like Ericsson refer to this as “cyber-physical continuity.”
The Internet of Sensors and Digital Twins
Ericsson aims to create an environment where real virtual experiences come to life in vivid detail through technologies like the “internet of sensors” and next-generation augmented reality glasses. Additionally, digital twin models will be enabled by 6G. These models allow experts to analyze what is happening in the physical world, simulate possible outcomes, anticipate needs, and then act back in the real world.
Uncertainties of the Future
While all these innovations sound exciting, there are still few details about what 6G technology will look like in practice. The International Telecommunication Union (ITU) standardizes wireless communication technologies every ten years, but how 6G will work is still unclear. Most experts estimate that 6G will start to be deployed around 2030, with commercial widespread use by 2032, as companies like Huawei and Ericsson are already laying the groundwork.
Conclusion
6G will not only increase internet speeds but also fundamentally change interactions between the digital and physical worlds. The ability to control machines with the mind, the safe navigation of driverless cars, and experiencing physical sensations in the virtual world are just a few examples of the future that 6G promises. Watching the development of this innovative technology will be a source of great excitement and curiosity in the coming years.
