China has realized the world's fastest real-time transmission for terahertz wireless communication (THz) which is 10 to 20 times higher than 5G networks, the Purple Mountain Laboratory announced on Tuesday.

With a home-developed 360-430 GHz high-end wireless communication system, the high-tech lab in Nanjing, capital city of east China's Jiangsu Province, has achieved 6G-oriented 100-200 Gbps (gigabits per second) real-time THz.

You Xiaohu, principal investigator of the lab, said that terahertz transmission technologies are fundamental for 6G networks and will be widely used for realizing faster transmissions and in new-type applications such as AR, VR and the metaverse.

Furthermore, terahertz technologies can also be extensively used in communication in space and between satellites and to eventually realize integrated space-earth-sea communication, You added.

A Chinese lab said it has made a breakthrough in next generation mobile communications technology, as the global power struggle over standards-setting in the telecoms industry continues to heat up.

A government-backed institute called Purple Mountain Laboratories said on Wednesday that a research team led by its chief scientist professor You Xiaohu had achieved a sixth generation (6G)-level wireless transmission up to a speed of 206.25 gigabits per second for the first time in a lab environment, according to a statement on its website.

The project was supported by a special government project on 6G and achieved in collaboration with telecoms giant China Mobile and Fudan University.

The speed achieved is a world record for real-time wireless transmission within the terahertz frequency band (300GHz~3THz), which is considered to be the bedrock for future 6G mobile communications, according to the Purple Mountain statement.

6G wireless communication technology will be the successor to current 5G cellular technology, which is still being rolled out across multiple countries. 5G enables data to be transferred at a speed that is 20 times faster than previous standards.

5G was designed to provide faster data rates, ultra-low latency, energy savings, cost reductions, higher system capacity and massive device connectivity, powering new smart services for consumers and an industrial upgrade.

The world has yet to agree on technical standards that would support 6G frequencies, signal modulations and waveforms. 3GPP, a leading global communication standards-setting organisation, has yet to announce a road map for 6G.

Chinese telecoms equipment giant Huawei Technologies Co, which is a leading provider of 5G network equipment, expects 6G tech to enter the market around 2030.

Ericsson, also a leading 5G equipment manufacturer, anticipates that early standards for 6G could be released in 2027, according to a report from Light Reading, an industry research group.

When asked about Huawei’s perspective on 6G, Huawei’s then rotating chairman Xu Zhijun told a press conference in September last year that “we don’t know what 6G is now”, although Huawei hopes to work with the industry to define what 6G is over the next decade.

China has the world’s largest number of 5G base stations. As of November last year, China had built and put into operation about 1.4 million base stations around the country.

However, the roll-out of 5G services has been slow, with the industry still struggling to find a killer application for everyday users due to high development and deployment costs.

CHINESE SCIENTISTS DEVELOP 6G TECHNOLOGY THAT MAY BE USED FOR HYPERSONIC WEAPON COMMUNICATIONS​

Terahertz waves used in 6G communication can penetrate plasma sheaths around model hypersonic vehicles

January 28 2022

Chinese scientists have demonstrated that next-generation terahertz technology could be used for hypersonic vehicle detection and tracking, an advance that can lead to new 6G communication applications for hypersonic missiles.

The new technology, described in the Journal of National University of Defence Technology on Tuesday, could solve some blackout problems that occur when attempting to establish communications with missiles or space vehicles traveling at five times the speed of sound or faster.


Typically, when a near-space hypersonic vehicle – either a spacecraft or a missile – travels through the atmosphere at speeds much faster than the speed of sound, the friction between its surface and the surrounding air forms a plasma sheath, according to scientists.


They said this layer of hot, ionised gas around the vehicle could lead to a communication blackout that may last up to 10 minutes – a problem known as the “black barrier.”

“Plasma sheath formed during the reentry of near-space hypersonic vehicle will interfere [with] the electromagnetic wave detection,” the scientists explain in the study.

In the new research, scientists, including Yao Jianquan from the School of Precision Instruments and Opto-electronics Engineering in China’s Tianjin University, built a laser device that could generate a continuous beam of electromagnetic waves in the terahertz band.


This frequency range between microwave and infrared is also used for next-generation 6G technology, which is expected to revolutionise communications.

Such communications systems get updated almost every decade and are also known as a generation or simply “G.”

In the new study, researchers built a model of a typical near-space vehicle and modelled the distribution of the plasma sheath under different flight conditions during the reentry process.

They also simulated the transmission characteristics of the terahertz electromagenetic wave in the plasma sheath.

Scientists could confirm using imaging experiments in the laboratory environment that high-frequency terahertz waves can penetrate plasma sheath effectively.

The terahertz waves could easily penetrate the plasma sheath produced by a hypersonic weapon at 10 times the speed of sound or even faster “as if the black barrier does not exist,” South China Morning Post reported.

While the commercial rollout of 6G technology is still not expected any time soon due to technical hurdles that still exist, experts said it could offer several new applications, including more accurate indoor positioning, improved automated driving and enhanced in-flight and on-the-move connectivity.

Apart from the advantage of streaming data hundreds of times faster, its higher sensitivity is also expected to allow better transmission of biological information such as data from exhaled breath and glucose levels, allowing the diagnosis of disease and detection of contagions.

However, earlier studies had cautioned that applications in hypersonic vehicles could be more challenging, since terahertz signals, particularly in the lower frequency range, could deteriorate while going through the plasma sheath.

While the new study did not assess the novel technology in an open environment, it suggested communication challenges with hypersonic vehicles can be tackled with better innovation.

“The simulation and experimental results preliminarily prove the potential of terahertz technology for hypersonic vehicle detection, which is of great significance for national defence,” the scientists wrote in the study.
