Race to 6G: Chinese researchers declare data streaming record with whirling radio waves

Experimental wireless line set up in Winter Olympics compound could stream over 10,000 high-definition live video feeds simultaneously, says Beijing research team

‘It is about introducing a new physical dimension, which can lead to a whole new world with almost unlimited possibilities,’ according to 6G researcher

Chinese researchers say they have achieved a record data streaming speed using a revolutionary technology that could help China take the lead in the global race for next-gen wireless communication, or 6G.

Using vortex millimetre waves, a form of extremely high-frequency radio wave with rapidly changing spins, the researchers transmitted 1 terabyte of data over 1km (3,300 feet) in a second.

The experimental wireless communication line, set up in the Beijing Winter Olympics compound last month, could stream more than 10,000 high-definition live video feeds simultaneously, the team led by Professor Zhang Chao, of the school of aerospace engineering at Tsinghua University in Beijing, said in a statement on Thursday.

The vortex waves, unlike anything in radio communication over the last century, added “a new dimension to wireless transmission”, said Zhang and his collaborators from Shanghai Jiao Tong University and China Unicom.

They said the experiment suggested China was “leading the world in research on potential key technologies for 6G”.
