Cutting-Edge Wireless Device Unveiled: 100 Gbps Sub-Terahertz Communication in the Era of 6G

NTT DOCOMO, NTT, NEC, and Fujitsu have collaborated to create a cutting-edge wireless device capable of ultra-high-speed 100 Gbps transmissions in the 100 GHz and 300 GHz sub-terahertz bands. This development is in preparation for the upcoming 6G era.

NEC developed a multi-element active phased array antenna comprising over 100 antenna elements after studying the wireless system configuration for telecommunications in the 100 GHz band. The company focused on enhancing signal amplification through compound semiconductor technologies, resulting in the highest power efficiency in a high-output amplifier for the 100 GHz and 300 GHz bands.

DOCOMO analyzed the wireless system configuration and performance requirements for 100 GHz telecommunications and developed equipment capable of achieving data rates equivalent to 100 Gbps at a distance of 10 meters. The company focused on developing software optimized for these high frequencies to maximize data transmission speeds.

Fujitsu conducted research on compound semiconductor technologies to enhance signal amplification, resulting in the highest power efficiency in a high-output amplifier for the 100 GHz and 300 GHz bands. The company also worked closely with NTT to develop testing equipment that could accurately measure transmission speeds over long distances.

The collaborative efforts of these four companies will continue as they delve deeper into sub-terahertz telecommunications, utilizing their respective strengths to contribute to the standardization of 6G technology.
