What is 6G? Crushing 5G no pressure May occur in 2030

5G has already been deployed, so what about 6G? What kind of technology is it? When will it come. Needless to say, in the end 6G will definitely replace 5G, which is not a functional technology and is still in its early stages of research and development. In 2019, Eric Sto Erik Ekudden said in an interview: “It’s a little early to talk about 6G.” “The focus is on 5G at the moment. But Erik Ekudden adds that it’s not early for the mobile industry to study the next generation of technology.

Now that we’ve just started to study 6G, when will it be launched? Erik Ekudden explains that it may be about 10 years before 6G arrives. In September 2019, Huawei founder Ren Zhengfei also told CNBC that 6G is still in its early stages of research and development and will have to wait at least 10 years. Japan’s NTTDoCoMo agrees. In its white paper, published in January 2020, NTTDoCoMo believes that mobile connectivity will evolve at a relatively stable rate, with 3G in the early 2000s, 4G in 2010 and 5G in 2020, so NTTDoCoMo believes that 6G will usher in a golden age by 2030.

How fast is 6G?

Sorry, so far, we don’t know exactly how fast 6G is. The final 5G standard will be developed by THE ITU, which began setting the standard for 5G in 2012 and was recently finalized, known as the IMT-2020 standard.

Although ITU has not yet set a standard for 6G, experts are already speculating about how fast 6G can be. Dr Mahyar Shirvanimoghaddam, of the University of Sydney, believes that 6G can reach speeds of 1TB per second. When we download a Netflix movie in 5G, the next one is only a few seconds, and if we download it in 6G, we can download a movie for 142 hours in a second.

In May 2019, ITU talked about the IMT-2030 standard, which describes a hybrid network, the equivalent of a 5G upgrade, and not a new 6G network.

How 6G will change

Researchers and scientists are saying that 6G will go beyond wired networks, where devices are connected and turned into antennas in the form of decentralized networks that are not controlled by a single network operations center. Because the device is super fast, when 6G arrives, the device’s instant connection to the device becomes possible.

In the 5G era, some applications will become more popular, such as driverless cars, drones, smart cities, and by the age of 6G, they will become more powerful, while 6G will also breed sci-fi applications such as connecting the human brain to computers and greatly enhancing touch control systems. “It’s entirely possible that we can implant wearables, microdevices, and connect the human body in real time, while also supporting human thinking,” ntTDoCoMo said. “

NTTDoCoMo also believes that with the arrival of 6G, some sci-fi scenarios will become a reality, and that induction interfaces will bring the senses to life, making it difficult to distinguish between true and false. By then, low energy consumption will be the focus, and the network will cover the ocean and space.

The most anticipated applications

In 2019, the industry published a report looking at 6G technology, which mentions three of the most promising applications of the 6G era:

– XR

XR technology in the 5G era will still have many limitations, and by the 6G era it will be further developed. A true immersive XR experience requires us to come up with a solution that combines engineering requirements (wireless, computing, storage) with perceived requirements (source human perception, physiological functions). In engineering processes (computing, processing), we take into account the minimum and maximum perceived requirements.


The so-called CRAS is connected robots and autonomous systems, including drone delivery systems, driverless cars, drone fleets, automotive fleets, autonomous robots and so on. CRAS will be one of the most important applications of the 6G era.


BCI is a wireless brain interaction technology. In a medical environment, humans can control prosthesis and nearby computing devices with brain implants, a technique we’ve seen. In the 6G era, wireless brain interfaces and implantation technologies will be further developed to find more applications. At that time, we will communicate with the environment and others through decentralized equipment, some devices on the body, some implants, and some into the surrounding environment.

Any of the above three applications will bring a new revolution to mankind.

Who’s developing 6G?

Like 5G, all big businesses and government agencies are working on 6G, and some are already discussing plans. For example, Japan recently developed a 6G project and met in January 2020 to announce its assistance in developing 6G standards and contributing to research.

In November 2019, a 6G research team was established in China. Finland has also established the 6G Flagship project, which is supported by Nokia, The University of Oulu and other organizations. Standards and other 6G issues will be discussed in Finland in 2019 and again in March 2020.

In South Korea, Samsung and LG have established 6G research and development centers, with SK Telecom, Nokia and Ericsson working together around 6G. Huawei has a research and development center in Canada, where it has already started researching 6G technology, and Ren confirmed that Huawei’s 5G and 6G studies were conducted simultaneously, long before Huawei was working on 6G.

In February 2019, U.S. President Donald Trump said the U.S. should step up its action in 5G and 6G, the sooner the better.


Ultimately, 6G data may be transmitted over very high bands, but the higher the band, the shorter the transmission distance, but the higher the data bandwidth. In other words, the higher the wireless frequency, the more information is transmitted, but the transmission is not as reliable as the low frequency, and the signal is easily blocked.

This is a challenge for 6G communication concept architects, and some solutions have been proposed. “If you want to reach 1Tbps at speed, transceivers have to introduce a whole new architecture, and computing needs to introduce a whole new architecture,” said Matti Latva-aho, a researcher at 6G Flagship. When THz is applied, there are many opportunities in semiconductors, optics, or materials. Technology is getting more complex, and we need an open source platform that uses it to nurture the next generation of hardware and software solutions. “

In essence, 6G requires a new look at technology. At that time, the network will move beyond the traditional base transport architecture and deploy more low-power antennas closer to the user. At this point, each networked device is both the device itself and the antenna. “The concept of the network is a bunch of cables that are connected, and then it fades and the data and semantic connections take over the stage,” explains Roberto Saracco, an Expert at EIT Digital. In hordes of devices, network intelligence will come to the fore. He thinks 6G will run on a real network of devices, and traditional base stations will not be able to meet demand. In the age of 6G, it is not network operators that bring about change to the network, but enterprises. More than that, some core technologies will spread rapidly, such as backscatter, which allows low-energy devices to connect through RF signals.

Satish Dhanasekaran, President of Keysight Technologies Communications Strategy Group, said: “Entering the 6G era, the instant messaging, AR experience will be completely different from today’s, and they will remove barriers to remote communication. “In some applications where people are not endpoints, such as industrial automation, autonomous systems, and large sensor networks, precise timing will be a key feature once 6G arrives. ITU calls this technology “Time Engineered Communications” and 5G’s goal is to keep latency as short as possible, while “Time Engineered Communications” in the 6G era is not the same. It focuses on the precise time of events, such as data transfer.

Roberto Saracco predicts that 6G will be a platform of services, service interactions, powered by parallel networks and decentralized controls; Because of this change, infrastructure owners, IoT device providers, and mobile phone manufacturers will have to adapt to new trends and change themselves.

From a technical point of view, 6G poses great challenges for communications engineers, and many technologies need to be innovated, such as materials science, equipment science, low-energy circuits, data simplification technology, network technology, biotechnology, and communication protocols. These are not the biggest challenges, the biggest challenge is how to manage development, and only then will the final network be resilient, resilient, support ingested application development, and ultimately allow heterogeneous networks to coexist seamlessly. On top of that, there is a challenge to keep large 6G networks stable and continuously transmit data at high speeds with low latency. So the development of 6G requires us to find breakthroughs in basic science and build large, ultra-stable, low-energy communication networks with new solutions.
