NIT Docomo and Metawave Announce Successful Demonstration of 28Ghz-Band 5G Using World's First Meta-Structure Technology

NTT DOCOMO, Inc., in collaboration with Metawave Corporation, announced the demonstration of a 5G mobile communication system using 28GHz-band 5G, and the world’s first meta-structure reflect-array technology. The world’s first successful demonstration took place in the world in Koto-ku, Tokyo on November 29, 2018. Meta-structures are an artificial medium with optical characteristics developed by arranging structures that are sufficiently small with respect to wavelength in the form of an array. The meta-structure reflector will be exhibited at the “DOCOMO Open House 2018. As a result of this demonstration the communication speed achieved was 560 megabits per second (Mbps) with Metawave’s meta-structures reflect-array in place, compared to 60 Mbps with no reflector. The meta-structures reflector developed by Metawave uses very small structures, compared to the free-space wavelength, that are arranged across the array to have different shapes based on their position within the array. It is possible to arbitrarily design the direction of the reflected wave gain and the shape of the beam (beam-width). Hence, it can be installed on walls of buildings to directly reflect waves in specific directions. As a result, the installation location in any given city is not limited, enabling the area to be expanded in high traffic areas. DOCOMO designed the 5G demonstration trial sites, considering the selection of installation location, beam control direction, etc. In the high-frequency bands used for 5G, it is difficult to expand the coverage area outside the line-of-sight of the base station antenna, and it is expected that industry will utilize the reflection of radio waves as a solution. A metallic reflector is one technique that has been tested, which reflects radio waves. However, this solution requires installation of a metal plate based on the direction of the incident angle of radio waves to control the angle of the reflected wave, which is difficult to install in cities, and is therefore limited to specific usage in the suburbs. In this demonstration, a meta-structure-based reflect-array was installed at the 5G trial site and was tested for covering a 5G area at the foot of a building, where a 5G base station radio was installed and a vehicle equipped with a 5G mobile station was used. As a result, the communication quality was greatly improved in the area where 5G data communication was previously impossible with range extension of about 35 meters. By using the meta-structures reflector, the communication speed improved by 500 Mbps for the vehicle equipped with the 5G mobile station. DOCOMO will continue to research and develop area building technologies using meta-structures in an effort to establish an efficient and flexible area construction method for the 5G area.

NTT DOCOMO, INC. to Set Up Test Lab in Guam for 5G Verifications in 2019

NTT DOCOMO, INC. announced that it will begin operating DOCOMO 5G Open LabTM GUAM as a 5G technology verification center in Guam next spring. The facility, DOCOMO's first overseas verification center, will be available for use by the more than 1,900 partners participating in the DOCOMO 5G Open Partner Program, which provides global businesses and organizations with the latest 5G information, test environments and opportunities for partner workshops. Program partners will be able to connect devices and services free-of-charge to the lab's 5G base and mobile stations and other equipment. Once the test environment is extended to outdoor locations during or after next summer, DOCOMO will also assist partners with their outdoor verifications. DOCOMO 5G Open Lab GUAM will enable partners to conduct fast, cost-effective testing of new services designed for U.S.-market technical and regulatory conditions and implemented in part with outsources devices and technologies. By offering a 5G test environment set up under U.S. conditions, DOCOMO 5G Open Lab GUAM will facilitate prompt, flexible and accurate verifications of equipment, systems and even advanced technologies for applications such as drones and autonomous vehicles. DOCOMO already operates 5G open labs in Tokyo and Osaka, and will launch a third domestic lab in Okinawa, Japan in December 2018. Going forward, DOCOMO will continue collaborating with enterprises and other partners from diverse industries to create innovative 5G services that will be used on DOCOMO's forthcoming 5G commercial network in Japan, which is expected to launch in 2020.
