Researchers MIEM HSE University has demonstrated the efficient operation of a 6G wireless communication channel at sub-terahertz frequencies for the first time in Russia. The device transmits data at a speed of 12 Gbit/s and maintains signal stability, automatically switching when blocked. The indicators correspond to international 6G standards. A description of some elements of the system is presented in article, published in the electronic press archive arXiv.
Scientists from MIEM HSE have demonstrated the efficient operation of a sixth-generation (6G) data transmission system for the first time in Russia. The experiment confirmed that the system can operate in laboratory conditions while maintaining high data transfer rates and communication stability. The demonstrator used frequencies of 141–148.5 and 151.5–164 GHz, and the data transfer rate reached 12 Gbit/s. These indicators correspond to international standards for communication channels of sixth-generation (6G) and IMT-2030 networks, in particular ETSI GR THz 002 V1.1.1 (March 2024) and the International Telecommunication Union (ITU) ITU-R M.2160.
The main feature of the system is the control of signal distribution in real time. If the signal is blocked, the system automatically switches to another antenna. This makes the connection stable even in difficult conditions. Some of the system components were developed at MIEM HSE and Moscow State Pedagogical University. For example, this is the RIS panel (compliant with ITU-R M.2541-0, May 2024), or frequency-selective surface, which controls the direction of signal transmission, as well as diode detectors that allow the system to operate at subterahertz frequencies.
Currently, the system’s range is limited by the size of the room, but this can be changed by replacing the antennas. The technology can be useful in high-speed communication networks, Internet of Things systems. Scientists plan to use machine learning to improve signal distribution and protection against interference.
“We have shown that the 6G system can reliably transmit data at the required frequencies and speeds. This is an important step for the development of communication technologies. In the future, we will work to make the system even more resilient using machine learning. For example, we plan to teach it to automatically control the signal beam so that the connection remains stable even when users are moving,” the director comments. Research Institute of Telecommunications MIEM HSE Professor Evgeny Kucheryavy.
The development has attracted the interest of telecommunications companies. Options for creating commercial devices that can compete with foreign analogues are already being discussed.
