China takes a big step towards developing 6G network, satellite Internet

China has made a major development in communications equipment that will help scientists move one step closer to developing a 6G network, the South China Morning Post reports.

According to the Xian Institute research team, scientists announced that they have successfully tested a device mounted on a satellite, capable of transmitting light signals from one place to another without converting them into signals. electrical signal, which acts more or less like a mirror. in optics and precision mechanics, under the auspices of the Chinese Academy of Sciences.

According to the academy, the device known as “space optical switching technology” was launched into orbit by China’s Y7 carrier rocket in August. The academy added that this was the first in China Such a device is tested on satellites.

Once downloaded, the image information carried remains intact without data loss. Switches are an essential part of a communication network, responsible for distributing data to a certain line. For example, when making a phone call, switches ensure that the call is routed to the intended recipient.

Traditional switches convert light signals into digital or simulated data, using electricity as the intermediary. However, the new device directly bypasses this process.

An optical scientist said the conventional photon-electron-photon method has an “electronic congestion” effect, while the optical method can maximize data exchange speed and capacity, China newspaper reported. Morning Post reported. One of the insiders, who is familiar with this test, said such an approach could reduce the cost of building special switching facilities.

According to a Chinese paper published by several team members last year, the device can support 40 gigabits per second of switching capacity, a significant improvement over traditional switching technology.

Developments such as satellite remote sensing, supercomputers involving large volumes of data, and 6G mobile communications are all leading to an increasing need for very high-speed and high-capacity information transmission.

To achieve this, industry experts say the revolutionary network of the future will require a three-way network, connecting communication nodes on the ground with satellites.

“Next-generation communications networks, including 6G, will go far beyond terrestrial connections; it must be a global network of satellite nodes,” the scientist said.
