Four firms, namely DOCOMO, NTT Corporation, NEC Corporation, and Fujitsu, formed a consortium for the project. Since 2021, these companies have collaborated on research and development concerning sub-terahertz devices, foreseeing the dawn of the 6G era.
To make high-speed 6G devices possible, the four participating companies each made significant contributions to the advancement of sub-terahertz technology.
DOCOMO conducted thorough analyses of wireless system configurations for 100 GHz telecommunications applications. Subsequently, they engineered wireless transmission equipment capable of delivering data rates of up to 100 Gbps across a 100-meter range.
NTT pursued the development of high-end wireless equipment while concentrating its efforts on 300 GHz devices. Their accomplishment resulted in the development of a top-tier 300 GHz band wireless device that can channel 100 Gbps per channel over 100 meters.
NEC committed its resources to research 100 GHz band-specific wireless system solutions. A complex multi-element active phased array antenna (APAA) with more than 100 antenna elements was created as a result of this project.
Fujitsu focused on developing novel technologies for compound semiconductors. Their work led to innovations that made it possible to amplify signals in the 300 GHz and 100 GHz bands with high efficiency and output.
Notably, with a high-output amplifier, Fujitsu achieved the highest power efficiency in the world, which is essential for increasing communication ranges while lowering power consumption at the same time.
This development of advanced 6G technologies has significant ramifications. The capacity achieved equates to five HD movies that could be streamed wirelessly every second, which opens up a plethora of possible uses for the data transfer speeds.
Experts highlight that possibilities are unlimited when it comes to offering seamless connectivity for future technologies, enabling applications ranging from ultra-HD video streaming to real-time control in autonomous vehicles, as well as increasing communication demands.
