Docomo and Nokia made first live 8K UHD video transmission via 5G


Mobile operator NTT Docomo and Finnish technology company Nokia announced through a press release that they have achieved first wireless real-time transmission of 8K video deploying an experimental 5G network.


The system uses beam-tracking techniques to transmit millimeter wavelength signals at an extremely high frequency of 70GHz. In the trial, 8K video of 48Gbps—a bit rate four times greater than 4K video and 32 times than Full HD—was compressed by the encoder into signals ranging from 145Mbps to 85Mbps and successfully transmitted without delay.


Docomo and Nokia have been collaborating since May 2014 to develop radio access technologies for future 5G mobile networks. Recent achievements include ultra-high-speed data transmission in excess of 2Gbps.
