A consortium of Japanese tech giants, including NTT DOCOMO, NTT, NEC and Fujitsu, have revealed the results of their real-world 6G speed tests.
This groundbreaking achievement shows the group's ability to achieve ultra-high-speed data transmission of 100 Gb/s, marking a pivotal moment in the advent of the 6G wireless communications era.
The four companies, which have been working together on the project since 2021, jointly developed a subterahertz 6G device and demonstrated their competence in 100 Gb/s transmissions in the 100 GHz and 300 GHz bands over distances of up to 100 meters. The achievement is exceptionally notable as it is approximately 20 times faster than 5G's current maximum data speed of 4.9 Gb/s.
Setting the 6G standard
Each of the four companies brings particular expertise to the project: DOCOMO developed the wireless equipment capable of handling these enormous data rates, NTT developed a device capable of transmitting 100 Gb/s per channel, NEC contributed a phased array antenna active multi-element amplifier, and Fujitsu showed world-leading efficiency in a high-performance power amplifier.
Despite the obstacles associated with the higher frequencies of the subterahertz band, companies believe that high-capacity wireless communications are possible. Leveraging each company's strengths, they are committed to continuing their collaborative research and development efforts to set the standard for 6G telecommunications.
When 6G eventually becomes widespread, it is expected to support various applications, such as ultra-HD video streaming and real-time control in autonomous vehicles. 6G technology like this could make 100 Gb/s transmission speeds the new norm.
The key assumption for these findings is the undisputed achievement of 100 Gbps transmission at a distance of 100 meters in the 100 GHz and 300 GHz bands, and the achievement of an equivalent isotropic radiation power of 50 dBm. It is important to note that actual data rates may vary depending on the communication environment and network congestion.
