Innovating the industry and pursuing growth

“Innovating the industry.” The strategy of ARTERIA Networks is not to compete with the three major telecommunication carriers on scale, but to continue innovating the industry and growing by providing unique services and detailed solutions.

An example of this is to provide efficient networks in anticipation of IoT (1*) and M2M (2*). ARTERIA Networks will also create new services that utilize its capital, such as the networks it has developed over the years, in response to the growing need for customers wanting to connect to “the cloud”. Also, by fully working with the Marubeni Group, ARTERIA Networks is also considering to provide services out of reach of the three major telecommunication carriers.

Under the keyword “Growth”, ARTERIA Networks will contribute to the development of society through the provision of ICT services.
