The World´s First 6G Technology From Japan
The network is capable of transmitting five HD movies per second and has the potential to revolutionize telecommunications, offering applications ranging from ultra-HD streaming to real-time communication.
Telecommunications Companies
Japanese telecommunications companies, including DOCOMO, NTT Corporation, NEC Corporation and Fujitsu, have announced the development of a 6G wireless device that promises to be 20 times faster than the 5G network.
According to the Engineering Today website, this new device reaches an “impressive speed” of 100 gigabits per second (Gbps) and can operate at distances of up to 100 meters.
Furthermore, it continues, the great innovation of 6G lies in the use of the so-called “sub-terahertz” bands, which vary between 100 and 300 gigahertz (GHz), considerably higher than those used in 5G, which normally do not exceed 40 GHz.
“With the ability to transmit five HD movies per second, 6G has the potential to revolutionize telecommunications, offering applications ranging from ultra-HD streaming to real-time communication in autonomous vehicles, satisfying a growing demand for faster data and connectivity” .
The companies announcing the world’s first 6G reveal that the challenge now is to develop new devices that work efficiently in these higher bands, as they require completely different technologies from those used today.
According to the website, each of the companies involved has brought its expertise to overcome the technical challenges and advance the development of 6G. For example, DOCOMO worked on developing wireless systems for the 100 GHz band, managing to transmit data at 100 Gbps for up to 100 meters; NTT focused on the 300 GHz band, creating a device capable of simulating performance over the same distance; NEC developed a complex active phased array antenna with more than 100 elements, essential for operation in the 100 GHz band; Fujitsu innovated in compound semiconductor technologies, increasing efficiency and signal amplification capacity at the high frequencies involved.
Announcement Contradicts China’s Prediction
According to a report published on June 23, 22, by the Techtudo website, China Mobile, the world’s largest telephone operator, released a technical study that suggested the architecture and design of the 6G network.
China’s forecasts pointed to gains of up to a hundred times compared to the current 5G, as well as greater reliability, with the implementation of the 6G network. However, the Japanese companies’ forecasts are the opposite.
By 2022, according to the news report, China would be leading the race to develop the 6G network, even with huge investments from companies in South Korea, the United States and Japan
