This technology enables data rates 10 times or more faster than that offered by the fifth-generation mobile networks (5G), expected to appear around 2020. Details of the technology will be presented at the International Solid-State Circuits Conference (ISSCC) 2017 to be held from February 5 to February 9 in San Francisco, California
The THz band is a new and vast frequency resource expected to be used for future ultrahigh-speed wireless communications. The research group has developed a transmitter that achieves a communication speed of 105 gigabits per second using the frequency range from 290 GHz to 315 GHz. This range of frequencies are currently unallocated but fall within the frequency range from 275 GHz to 450 GHz, whose usage is to be discussed at the World Radiocommunication Conference (WRC) 2019 under the International Telecommunication Union Radiocommunication Section (ITU-R).
