China tests 6G technology from space

While the beginning of the 6G technology race has barely taken shape, China Mobile - the world's largest network operator - in early February launched a 6G test satellite in low Earth orbit.

This will help reduce latency and transmit data at extremely high speeds, supporting advanced technology applications deployed on Earth.

Currently, 5G networks are the technology prioritized for deployment by most countries around the world. They have significantly improved performance compared to 4G.

China has begun testing 6G technology in space. China Mobile recently launched the world's first satellite dedicated to 6G testing, this information was confirmed by China Daily.

Aiming for 1 Terabit per second throughput

This satellite is located in low Earth orbit (LEO), about 500km from Earth. This is the world's first satellite for 6G testing, by China Mobile in cooperation with the Chinese Academy of Sciences. develop.

The low orbit will promote fast data transmission and reduce latency compared to other satellites, operating 36,000km above us.

The idea is that when the 6G network is deployed, it can fill in the "gaps" on Earth through a satellite system in space - meaning, the 6G network will be usable anywhere. on earth.

From a theoretical perspective, 6G technology promises to be able to transmit speeds of up to 1 Terabit per second (1,000 Gigabits per second) and almost zero latency.

On the other hand, 6G will be especially suited to the Internet of Things - the ability to detect and link multiple connected devices or vehicles within a certain radius.

Even though 6G technology is being tested by China, scientists say it still cannot be commercialized before 2030.

This technology promises data transmission 100 times faster than 5G, as well as latency reduced to less than one millisecond.

6G also helps with lossless data transmission and reduced energy consumption. Besides, 5G technology uses millimeter frequencies of up to 30 gigahertz, 6G will use the terahertz band - said to be suitable for extremely high-speed data transmission.

What is 6G network?

The sixth generation 6G network, following the 5G generation. The specific standards are unknown, but we can completely speculate what characteristics the 6G network will have. According to PCMag, new generations of mobile networks use advanced digital encryption. In addition, 6G network also supports bandwidth, wider coverage and is smarter.

What's different about 6G network?

The difference we can see most clearly is speed. After each generation of mobile networks, speed will be an improved factor and so is the 6G network. The 6th generation mobile network uses more advanced equipment, has larger and more diverse waves. This includes the Extreme High Frequency spectrum providing great speed and capacity. To easily visualize, you can see the speed comparison table between 4G, 5G and 6G networks as follows:
