MIRAIT and METAWAVE conducted indoor demonstration test of ECHO™,a reflector using metamaterial technology for 5G area construction
MIRAIT Corporation (Headquarters: Koto-ku, Tokyo; President: Toshiki Nakayama; hereinafter, MIRAIT) , which
is a Group company of MIRAIT Holdings Corporation, and Metawave Corporation (Headquarters: Palo Alto,California, USA; CEO: Maha Achour, hereinafter Metawave) conducted radio wave propagation experiments in thequasi-millimeter wave band using metamaterial reflectors. They confirmed that the result reached the expected
performance level.
MIRAIT is working to accelerate the technological development of the next-generation 5G mobile communication
system, and emerging enterprise local 5G which will start in earnest in the spring of 2020. Metawave has state-ofthe-art technology in this field, and since last December, and MIRAIT has been evaluating to confirm the practicalityof Metawave’s metamaterial reflectors which are attracting attention as an effective tool for building 5G areas. In
this experiment, basic electromagnetic coupling and radiation characteristics such as the reflectance of themetamaterial reflector were confirmed. From here on, the two companies will confirm the effectiveness ofmetamaterial reflectors in 5G area construction based on a series of processes such as 3D data conversion of indoor
space, radio wave propagation simulation, and reflector design.
MIRAIT has been engaged in the electrical equipment business, software business, and ICT business for many years,
focusing on the construction of fixed communication equipment and mobile network equipment. MIRAIT strives
to provide new solutions that meet the demands of society with the aim of realizing smart offices and smart towns
by strengthening the business base with the engineering skills in each field.
Metawave is a U.S. startup with state-of-the-art technology in the field of developing 5G radar platforms thatenhance the performance of radars used in 5G area expansion and autonomous driving. Metawave ECHO™ passivereflectors enable faster, more efficient 5G and fixed wireless deployments to bring high-speed connectivity tobillions of users as they connect indoors and outdoors around the world.
Based on this experiment, MIRAIT and Metawave will continue to actively accumulate knowledge on the practicalapplication of new technologies for building 5G areas. Both companies aim to creating efficient and detailed areasusing quasi-millimeter waves in 5G, which is expected to be widely used, for building private networks such as
construction sites, logistics / warehouses, stadiums, hotels, office buildings, and the like as well as
telecommunications carriers.
*1 Reflector using metamaterial technology
Metamaterials are artificial materials that behave in response to electromagnet ic waves including light,
which are not found in natural materials. Purpose of applying the metamaterial reflectors for constructing
5G areas using millimeter waves and quasi -millimeter waves is to expand areas (outdoors / indoors) whereotherwise impossible due to the effects of shielding.
*2 ECHO（TM）
ECHO (TM) is a quasi-millimeter wave reflector developed by Metawave, which uses metamaterialtechnology.

*3 Quasi-millimeter wave band
In high-frequency radio, a wavelength band whose wavelength is close to millimeters. The area around 20
GHz to 30 GHz is often called a quasi -millimeter wave. Until now, it has not been used in the field ofmobile communications, so there is room in the fr equency bandwidth, and it is suitable for ultra -highspeed, large-capacity communications. On the other hand, there is a problem that the straightness is higher
than the frequency band used conventionally, and the amount of attenuation due to rainfall or s hielding islarge, but this has been solved by utilizing a reflector using metamaterial technology.
