we are aiming to build and introduce high quality communication environments into companies andlocal governments in Japan.
On the other hand, in Korea, which is known as a telecommunications superpower, ELUON was
considering entering Japan to take advantage of its experience in developing 5G core network
systems for major telecommunications carriers and building private networks for companies and local
governments and developing/introducing advanced solutions such as providing MEC (standards foredge computing in 5G environments) platform technology. For this reason, ELUON wanted apartnership with a local company with sufficient experience having technical capabilities in the field oftelecommunications to expand telecommunications solutions business and cultivate Japanesemarket.
Under the circumstances, both companies evaluated each other's experience, technologies, andachievements, and confirmed that the goals were the same, and therefore signed the agreement atthe venue of MWC Barcelona, the world's largest event related to mobile communication, wheremobile carriers, device manufacturers, and content providers from all over the world exhibit, as asymbol of the latest technological trends such as 5G and 6G.
