MIRAIT starts to sell 5G Area Construction Reflector "KLONE™"
applying Metamaterial/Metastrucuture technology
MIRAIT concludes agreement with METAWAVE of the United States of America
on sales of reflector “KLONETM” targeting the deployment of Local 5G WirelessArea Construction Solutions

MIRAIT Corporation(Head Office: Koto-ku Tokyo, President: Toshiki Nakayama) a Group companyof MIRAIT Holdings Corporation,has entered into a license agreement with Metawave Corporation(Headquartered in Palo Alto, California, CEO: Maha Achour, Metawave), a U.S. start-up and adeveloper of Metawave "KLONETM”
technology*2*1

passive reflectors using metamaterial/metastructure, which is attracting attention as an effective tool in "Local 5G Wireless Area

Construction Solution" and started sales on November 20.
1. Practicality of KLONE reflectors in "Local 5G Wireless Area Construction Solution"
In June 2020, as part of its "Local 5G Wireless Area Construction Solution" MIRAIT began providing
support for companies implementing local 5G systems through its construction consultation
services including design, construction, and support for license application. Currently, thequasi-millimeter wave band *3, which is assigned to the local 5G, has the problem of being a blindarea due to the straight propagation of radio waves. To solve this problem, KLONE reflectors realize
efficient and economical wireless area formation.
The KLONE reflector is a product developed by Metawave that uses metamaterial/metastructuretechnology to enable passive beamforming. Since December 2019, in collaboration with Metawave,
MIRAIT has been conducting propagation tests, channel analysis, trial manufacture, andperformance evaluation of KLONE reflectors as passive reflectors in constructing a local 5Gwireless area. The metamaterial/metastructure technology used in the KLONE reflectarray hasreflective properties that are not found in nature and it is expected to be possible to create awireless area that does not take up space, does not feel oppressive, does not consume any power,
does not require permits or licenses, and does not spoil the aesthetics of the area.
2. Future development
MIRAIT will continue to expand and enhance its services of "Local 5G Wireless Area Construction
Solution", and contribute to the formation of efficient and detailed 5G service areas using
quasi-millimeter waves, which are expected to be widely used not only by telecommunications
carriers but also at construction sites, logistics and warehouses, stadiums, hotels, office buildings,

and other facilities aiming to build private networks. In addition to the construction of local 5G
wireless areas, MIRAIT aims to provide comprehensive network construction that combines LPWA
and Wi-Fi.
For many years, MIRAIT has been engaged in the electrical equipment business, software business,
and ICT business, focusing on engineering related to the construction of fixed communications
facilities and mobile network facilities for telecommunications carriers. Based on the engineering
capabilities that have been refined in various fields, MIRAIT aims to provide new solutions that
support a smart society through "Total Engineering & Services".
*1 Reflector applying metamaterial /metastructure technology
Metastructures are structures that behave in response to electromagnetic waves including light, which are notfound in nature. Purpose of applying the metamaterial/metastructure reflectors for constructing 5G areas using
millimeter waves and quasi-millimeter waves is to expand areas (outdoors / indoors) where otherwise
impossible due to the effects of shielding.
*2 KLONETMKLONETM is a quasi-millimeter-wave reflector developed by Metawave, which uses metamaterial/metastructuretechnology.
*3 quasi-millimeter band
Quasi-millimeter wave band in high-frequency radio, a wavelength band whose wavelength is close tomillimeters. The area around 20 GHz to 30 GHz is often called a quasi-millimeter wave. Until now, it has notbeen used in the field of mobile communications, so there is room in the frequency bandwidth, and it is suitablefor ultra -highspeed, large-capacity communications. On the other hand, it is highly linear and there is aproblem that the amount of attenuation due to rainfall or shielding is large, but this has been solved by utilizinga reflector using metamaterial technology.
