Nokia Begins Key Tests on 4.5 GHz Band with DOCOMO to Develop 5G Ecosystem in Japan


Nokia has been working with NTT DOCOMO in Japan to develop a 5G ecosystem. The collaboration - which uses the Intel® 5G Mobile Trial Platform - will commence with the key interoperability testing of multi-vendor technology using the 4.5 GHz frequency band.

5G will deliver high speeds and low latency in support of a new generation of broadband applications, meeting new requirements for connecting people and devices, especially in megacities such as Tokyo. Nokia will conduct trials of 5G technology with DOCOMO in the Tokyo metropolitan area throughout 2017, with particular focus on busy tourist, shopping and business locations as well as at key public events hosted by the operator.

The tests will use the Nokia 5G FIRST solution, incorporating the Nokia AirScale base station transmitting over a 5G radio interface to the Intel® 5G Mobile Trial Platform. The companies will test end-to-end applications over the air between the base station and the device on the 4.5GHz frequency band, which is one of the candidate bands for 5G in Japan. The Nokia 5G FIRST solution is based on early-adopters radio specifications that define a common interface to allow equipment from multiple vendors to connect over a 5G radio network.

Nokia is working with industry leaders around the globe to deliver a 5G infrastructure that will meet the massive broadband needs of a variety of industries and applications. This trial is an important milestone for the development of 5G in Japan, which will be one of the first countries in the world to adopt the technology. Furthermore, the initiative is an important step forward in the collaboration of Nokia with NTT DOCOMO, as well as other key technology partners, as they develop a technology that will meet the ever-growing demands of huge numbers of people living in megacities.

A demonstration of the end-to-end tests supporting low-latency 4K video streaming and other 5G applications will be given at the Nokia booth at 5G Tokyo Bay Summit 2017.
