MESSAGE
Establishing a New Standard for Infra-Sharing Once Again
Infra-Sharing is currently at a major turning point.
With the promotion of 5G, the spread of AI, and the acceleration of digitalization, the utilization of Infra-Sharing has advanced further, and the roles and services required have transformed into something broader and more sophisticated. While demand continues to expand, new challenges have emerged that we must resolve together with mobile network operators and society at large—such as establishing more efficient network deployment methods and building operational structures that are sustainable for the long term.
As the pioneer of Infra-Sharing in Japan, JTOWER has opened up the market by creating new value.
We are more than just a service provider; we bear the responsibility of ensuring the healthy and continuous growth of this market. While continuing to respond sincerely to diversifying needs, we will further accelerate our commitment to new challenges to raise the industry standard to the next level.
The core of this challenge lies in our commitment to engineering excellence.
Since our founding, we have consistently developed our own sharing equipment in-house. We do this to directly address the detailed needs of mobile network operators and the challenges faced by facility owners.
In the rapidly evolving world of telecommunications, we not only respond quickly to new communication standards but also continue to update performance by introducing advanced technologies. Furthermore, we take an uncompromising approach to improving resource and operational efficiency through measures such as power saving, miniaturization, and the integration of AI in operations.
To deliver superior technology to society, we will continue to hone the "dual wheels" of our core strengths—technology (hardware) and service (software)—while remaining dedicated to being an organization that consistently provides our customers with value that is always one step ahead.
Believing in the potential of Infra-Sharing, JTOWER will forge ahead for the further development of the Japanese telecommunications industry with technological innovation, flexible responsiveness, and unwavering neutrality. We will create a more evolved and new standard for Infra-Sharing once again.
