The operator and network technology and management vendor claim a world first in transmitting 8K video compressed from 48 Gigabit/s baseband signal down to between 145Mbps to 85Mbps, over fifth generation network, on May 19.
The transmission of ultra-high-resolution 8K video was achieved by a combination of an experimental system jointly developed by DOCOMO and Nokia, and H.265/HEVC encoding techniques developed by NTT Media Intelligence Laboratories. 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 at the Roppongi Hills high-rise complex in Tokyo.
Glenn Booth, till recently working at Nokia's recent acquisition Alcatel Lucent, and now Vice President and General Manager, 5G Business Line at Nokia, said: “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.”
DOCOMO is also working with Ericsson on 5G technology, in this case at 15 Gigaherts where as Nokia uses 70 Gigaherz. In Februari Ericsson and DOCOMO reached an accumalitive throughput of 20 Gigabit/s.
In a joint 5G technologies trial, the companies achieved a cumulative 20Gbps of data throughput in an outdoor environment using the 15GHz frequency band with two simultaneously connected mobile devices of a downlink bit rate of over 10Gbps each, on February 21. The data speed satisfies one of the key requirements for future 5G commercial services.
The companies also succeeded in a separate trial on February 21, data throughput exceeding 10Gbps at a distance of approximately 70 meters from the base station, or about 7 times farther than the distance achieved in a past trial. Moreover, the data transmission exceeding 9Gbps at a distance of about 120 meters from the base station was also succeeded.
5G will use high-frequency bands, which are inclined to experience attenuation in speed and capacity as they travel over long distances.
The trial, which took place at the DOCOMO R&D Center in the city of Yokosuka, Japan, utilized a specification defined jointly by DOCOMO and Ericsson, and an Ericsson 5G Radio Prototype and user devices, in place of mobile phones, from Ericsson.
NTT DOCOMO also led vendors and operators in setting up an open specification for trials using various frequency bands for the next generation of mobile communictaions networks.
NTT DOCOMO, SK Telecom and Verizon have agreed to form a new global initiative, called the 5G Open Trial Specification Alliance. This alliance plans to develop an aligned 5G trial specification that would serve as a common, extendable platform for different 5G trial activity around the world, focused on technical fundamentals and promoting a more inclusive, open, and collaborative approach to the development of 5G trial networks.
The 5G Open Trial Specification Alliance will focus on 5G radio interface trial activities and aims to provide the wireless industry with the ability to test and validate key technical components. Coordination is already underway, with technical trials occurring in the 2016-2018 timeframe.
The development of the trial specification will allow a variety of different industry partners (network vendors, chipset/device vendors, operators, test equipment vendors, etc.) to join and contribute.
The trial specification will be neutral and is not intended to limit on-going standardization discussions and decisions that will be happening in 3GPP. Rather its objective is to provide a common trial platform where different technology components can be trialed and evaluated in order to provide a better understanding of the value and performance of different 5G technologies. This can provide valuable input in the upcoming 3GPP discussions, by complementing simulation studies with real data from different trial deployments.
The trial specification will cover multiple spectrum bands, including bands above and below 6 GHz.
The interest for 5G is very high, and many players are engaging in activities to support the early commercialization and deployment of this next generation technology. The 5G Open Trial Specification Alliance is positive that this initiative will provide a platform to maximize the value of different trial activities around the world, and will provide valuable input from these trials to 3GPP.
So far KT, NTT DOCOMO, SK Telecom, Verizon, as well as some of their key suppliers have committed to this initiative, and other key industry participants are expected to join the alliance in the future. Our trial specification is intended to be in public to accelerate the ecosystem to bring 5G to market.
