Humanity needs crazy data transfer speeds

With the development of technology, the need for faster data transfer is increasing, especially with the emergence of augmented reality, “smart” homes and robotic surgeons. 6G generation mobile communications are ready to use the sub-terahertz frequency range and multi-level signal modulation technology to enable high-speed data transmission.

However, the challenge is to reduce crosstalk and phase noise, which can affect the performance of multi-level signal modulation at very high speeds.

Using the power of the VRMB laser, the team from Osaka University tried to solve this problem by amplifying the light using sound waves and creating a precise signal. This innovative approach overcame limitations hindering communication at 300 GHz by significantly reducing phase noise.

Scientists have created a communication system at a frequency of 300 GHz with a signal generator in the receiver and transmitter, which includes digital signal processing (DSP or DSP) to demodulate the signal and increase the data transfer rate.

The remarkable result of this work was the record speed of data transfer 240 Gbit/s on single channelIt has become an important milestone in the worldwide development of COS-based systems. With improvements in channel compression techniques and the development of more sensitive receivers, researchers plan to further increase the data rate, aiming to reach an impressive figure in the future. 1Tbit/s.

The future of mobile communications

The sixth generation of mobile communications promises a 50-fold increase in data transfer speeds and a significant 10-fold reduction in signal latency compared to the previous 5G. A recent achievement by Japanese scientists lays a strong foundation for the future of high-speed wireless communications and will have implications for various technological fields.
