Japanese telecommunications companies have recently developed high-speed 6G wireless equipment that can transmit data at 100 Gbps over a distance of 100 meters. The alliance, consisting of DOCOMO, NTT Corporation, NEC Corporation, and Fujitsu, worked together on this device development project in 2021. These companies are collaborating on research and development of near-terahertz devices to pave the way for the 6G era, as reported by Interesting Engineering on May 2.
The significant difference between 5G and 6G lies in the frequency range of the electromagnetic spectrum used by the network. While 5G operates in the sub-6 GHz band and extends into higher millimeter wave bands around 40 GHz, 6G networks will require even higher frequency bands in the near terahertz range, between 100 and 300 GHz. Developing wireless equipment for these sub-terahertz frequencies presented challenges that the companies had to overcome, including establishing performance standards for devices operating in this range.
DOCOMO focused on wireless system configuration analysis for 100 GHz applications, adapting the transmitter to achieve data transmission speeds of up to
