A consortium of Japanese tech giants, including NTT Docomo, NTT, NEC, and Fujitsu, has published the results of their real-world 6G speed tests.
This breakthrough achievement demonstrates the group’s ability to realize ultra-high speed 100Gb/s data transmission, marking a pivotal moment in the advent of the 6G wireless communication era.
The four companies, which have been collaborating on this project since 2021, have jointly developed sub-terahertz 6G devices and demonstrated a transmission capability of 100Gb/s at distances of up to 100 meters in the 100GHz and 300GHz bands, which is approximately 20 times faster than the current maximum 5G data rate of 4.9Gb/s, a highly noteworthy achievement.
Setting 6G standards
Each of the four companies brought its own expertise to the project: Docomo developed radio equipment capable of handling the massive data rates, NTT developed devices capable of transmitting at 100 Gb/s per channel, NEC provided multi-element active phased array antennas, and Fujitsu demonstrated world-class efficiency in high-output power amplifiers.
Although there are challenges associated with the higher frequencies in the sub-terahertz band, the two companies believe it is possible to achieve high-capacity wireless communications, and will continue to work together on research and development, leveraging each company’s strengths, in an effort to establish standard specifications for 6G communications.
When 6G eventually goes mainstream, it is expected to support a variety of applications, such as ultra-high-definition video streaming and real-time control of autonomous vehicles, and 100Gb/s transmission speeds are likely to become the new standard with 6G technology.
The main premise of these results is that 100Gbps transmission can be reliably achieved over a distance of 100 meters in the 100GHz and 300GHz bands, with equivalent isotropic radiated power reaching 50dBm. Please note that the actual data rate may vary depending on the communication environment and network congestion.
