China has tested a promising network designed to transmit data through the air, the South China Morning Post reports.
Experts from Tsinghua University’s School of Aerospace Engineering, led by Professor Zhang Chao, installed an experimental wireless system at the Beijing Olympic Games complex. During the test they set a speed record for data transfer – files larger than 1 Tbyte were transferred at a distance of about 1 km, and the process itself took less than one second.
This achievement was made possible through the use of high-frequency radio waves, known as millimeter-wave vortices. Scientists believe that the described technology can be used in 6G data transmission. A station based on vortex millimeter waves can simultaneously transmit more than 10,000 high-definition video transmissions.
“We are talking about the introduction of a new physical dimension, which could lead to a whole new world with almost unlimited possibilities,” the scientists stressed. Today, China leads the way in researching potential key technologies for 6G, with 40 percent of the world’s patents relating to sixth-generation communication technologies registered here.
Notably, in 2020, the Japanese company Nippon Telegraph and Telephone used eddy millimeter waves to transmit data at speeds of more than 200 Gbit/s over a distance of up to ten meters.
