NTT DOCOMO, partnering with Ericsson has announced recently that its joint 5G outdoor trial achieved a maximum data transmission speed of over 4.5Gbps using the high-frequency 15GHz spectrum band. This is the first phase of trials designed to pave the way for DOCOMO's deployment of a commercial 5G network by the Tokyo 2020 Olympics and Paralympic Games in July 2020.
According to NTT DOCOMO, a separate indoor 5G trial was conducted with Nokia Networks in December last year to verify beamforming, a technique for more stable high-speed data transmission using exceptionally higher frequencies in the 70GHz band whereby it achieved data transmission rates of above 2Gbps. DOCOMO also announced that it has agreed with its two newest partners, Huawei and Mitsubishi Electric, to conduct technical verifications of emerging 5G mobile communications technologies using various frequency bands, including lower than 6GHz and extremely high frequencies, called millimeter waves. In total, DOCOMO's 5G trials now encompass eight blue-chip mobile technology vendors, also including Alcatel-Lucent, Fujitsu, NEC and Samsung.
Ulf Ewaldsson, SVP & CTO, Ericsson
As an industry leader in telecommunications systems, Ericsson is at the forefront of 5G system definition, research and standardization. One of our key success factors has been to foster industry collaboration at a very early stage, and work with select markets and key customers. Japan is one of the leading countries for high technology research, implementation and adoption, and DOCOMO is one of the leading service providers who have played an instrumental role in shaping previous technology generations. We are proud to be working with DOCOMO in Japan, as one of our lead 5G customers and markets, and are delighted at the demonstrated capabilities of next gen 5G technologies via our joint test bed programme. We look forward to many more milestones and in setting the industry pace and shaping the 5G direction together.
Ryan Ding, Executive Director of Board & President, Products and Solutions, Huawei
5G will be the cornerstone for building a more connected world and transforming our lives and work for decades to come. Realizing a 5G market will require joint efforts spanning different industries and ecosystems, so I am pleased to collaborate with DOCOMO on creating 5G technologies from the early stage. I believe that by working with DOCOMO, we will be able to offer the many benefits of 5G technologies to our customers.
