It is estimated that 6G will not be commercialized until 2030 and that the first real use cases for this network could occur between 2026 and 2028. Tsinghua University successfully completed the world’s first W-band vortex electromagnetic wave orbital angular momentum (OAM) 1Tbps high-speed relay transmission demonstration and verification experiment, laying a key technical foundation for OAM technology for future mobile communication applications.
Using millimeter vortex waves, an extremely high-frequency radio waveform, researchers have transmitted 1 terabyte of data in one second over 1 km.
The experimental wireless communication line, installed last month at the Beijing Winter Olympics site, can support more than 10,000 live high-definition video streams simultaneously, the team, led by Professor Zhang Chao of the Department of Aerospace Engineering at Tsinghua University in Beijing, said in a statement.
This technology would support 10,000 live high-definition video streams simultaneously
The benefits are many: latency will be reduced to 0.1ms (it is 1ms for 5G) and download and upload speeds will be multiplied to reach peaks of up to 1,000Gbps.
The problem with these waves, however, is that their size increases with distance and the signal becomes weaker, making high-speed data transmission over long distances difficult. However, the Chinese researchers have developed a solution, namely a transmitter that can create a smaller vortex so that the waves can rotate in three different ways and store more information. They also used a receiver that can receive this data and decode it instantly.
