Four Japanese tech giants, including NTT DOCOMO, NTT, NEC and Fujitsu, have revealed the development of a 6G wireless device capable of ultra-high-speed 100Gbps transmissions in the 100GHz and 300GHz sub-terahertz bands over distances of up to 100 metres.

As a comparison, 100Gbps is approximately 20 times faster than the maximum 4.9Gbps data rate of current 5G networks.

Since 2021, these four tech firms have been working together to conduct R&D on sub-terahertz devices in anticipation of the coming 6G era.

When this era does arrive, wireless networks will need to be able to support diverse applications, from ultra-HD video streaming to real-time control in autonomous vehicles. To achieve this high-capacity wireless communication, the abundant bandwidth available in the sub-terahertz band from 100GHz to 300GHz will need to be exploited.

In order to carry out this 6G test, each of the four companies brought their own particular expertise to the project.
