NTT Docomo, INC., NTT Corp., NEC Corp., and Fujitsu Limited jointly announced recently the development of a top-level wireless device capable of ultra-high-speed 100 Gbps transmissions in the 100 GHz and 300 GHz sub-terahertz bands.

The four companies have been jointly conducting R&D on sub-terahertz devices since 2021 in anticipation of the coming 6G era. To date, tests of a jointly developed wireless device have achieved ultra-high-speed 100 Gbps transmissions in the 100 GHz and 300 GHz bands at distances of up to 100 meters. By comparison, 100 Gbps is approximately 20 times faster than the maximum 4.9 Gbps data rate of current 5G networks.
