DOCOMO Tests Real Time 8K Video over 5G with Nokia

NTT DOCOMO successfully tested the real time transmission of 8K video over a 5G communications system.

The trial, which was jointly conducted with Nokia on May 19, employed H.265/HEVC encoding techniques developed by NTT Media Intelligence Laboratories. The trial system used beam-tracking techniques to transmit millimeter wavelength signals at an extremely high frequency of 70GHz.  The 8K video signals were ingested at 48 Gbps — a bit rate four times greater than 4K video and 32 times than Full HD — and then compressed by the encoder into signals ranging from 145 Mbps to 85 Mbps 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 at the Roppongi Hills high-rise complex in Tokyo.

"We are excited to be collaborating with DOCOMO to shape 5G and show how this technology can be used to dramatically enhance the delivery of services such as video. This world's first demonstration is a clear indication of our progressive leadership in 5G. We will continue to leverage our expertise and work with industry leaders including DOCOMO to drive further innovation in the industry," stated Glenn Booth, Vice President and General Manager, 5G Business Line at Nokia.
