Tencent Technology News reported on May 6 that according to foreign media reports, a consortium of Japanese companies has successfully created the world's first high-speed 6G wireless device, which can achieve a data transmission speed of 100 Gbps per second within a range of more than 90 meters, which is 20 times faster than the current 5G technology. Such a data transfer speed also means that 5 HD movies can be transmitted wirelessly per second.

According to Statista, this speed is even more than 500 times faster than the average download speed of T-Mobile's 5G phones in the United States. T-Mobile's average 5G speed in the U.S. is only 204.9 Mbps per second, which is still far from the theoretical maximum speed of 5G.

The prototype is the result of a collaboration between major Japanese telecommunications companies such as DOCOMO, NTT, NEC, and Fujitsu.

The latest test data reveals that the device achieves a transmission speed of 100 Gbps per second in the indoor band of 100 GHz, and also shows excellent performance in the outdoor band of 300 GHz. It is worth mentioning that the 300 GHz band is located in the lower part of the electromagnetic spectrum in the infrared light. In their statement, representatives of the Nippon Foundation made it clear that the tests were successfully carried out in the air at altitudes of up to 100 meters.

However, according to the GSM (Global Mobile System) Association, scientists have already begun to build the 6G standard, and the construction of related infrastructure is also in full swing, and it is expected to be officially launched around 2030.

The main difference between 5G and 6G is the frequency band of the electromagnetic spectrum they use. 5G signals are typically transmitted in frequency bands below 6 GHz and extend to frequency bands around 40 GHz, the so-called "mmWave band". And 6G is expected to operate in higher frequency bands, the so-called "sub-terahertz" bands, between 100 GHz and 300 GHz.

While these bands can lead to faster speeds, they also come with challenges such as greater sensitivity to environmental interference and easier signal blockage in indoor environments.

The leap from 4G to 5G has set the stage for a surge in media consumption, while the leap from 5G to 6G promises to usher in a new era of holographic communications and smoother, more realistic virtual reality (VR) and mixed reality (MR) experiences.

However, since 6G relies on higher frequency bands, we need a whole new infrastructure to support signal transmission and amplification, as well as smartphones or VR devices that need to be equipped with 6G antennas. 

In previous tests, scientists had achieved faster 6G speeds, but often only covered shorter distances. For example, another team of scientists in Japan has demonstrated 6G speeds of up to 240 Gbps, but only at a range of 20 meters. (Compiler/Golden Deer)
