JTOWER conducts the demonstration project of Indoor 5G Infra-Sharing in Vietnam -Installation and operation of the 5G indoor Infra-Sharing network at retail facilities in Vietnam for the introduction of Japanese 5G technology and experience-

JTOWER Inc. (Representative Director: Atsushi Tanaka, Headquarters: Minato-ku Tokyo) (“JTOWER”), announces that the company has been adopted for the Ministry of Internal Affairs and Communications’ FY2022 demonstration project of indoor Infra-Sharing in the Socialist Republic of Vietnam. In order to introduce Japanese 5G solutions into ASEAN region, JTOWER will conduct the demonstration project of the 5G indoor Infra-Sharing in Vietnam, by utilizing its technology and experience of 5G in Japan, .

■Background of implementation
The Ministry of Internal Affairs and Communications has a mission to expand digital infrastructures and digital technologies to abroad in order to contribute to the global dissemination of safe and secure 5G, which are the foundation of digitization, and to develop an industrial foundation based on 5G..
In Vietnam in particular, the mobile phone penetration rate has grown by more than 100% in line with high economic growth, and demand for mobile communications infrastructure continues to rise. The Vietnamese government announced its policy to grant 5G licenses to mobile network operators in 2023, and therefore further growth in demand for 5G network infrastructures is expected in the future.
In 2020, JTOWER completed the development of multi-carrier sharing equipment compatible with 5G Sub6 frequency band and started its commercial operation from the project of Tokyo Metropolitan Government’s TMG No.1 Building in November 2020, which is the first indoor 5G Infra-Sharing in Japan. JTOWER’s track records of 5G indoor Infra-Sharing has been expanding and the company will utilize its experience into the demonstration project.

■Overview of project
In the demonstration project, JTOWER will build and operate a 5G communications network through Infra-Sharing at a commercial facility in Vietnam with high communications traffic demand to support early deployment of indoor 5G in Vietnam. In addition, the company will provide VR contents utilizing 5G and verify the utilization of large-volume data. With the demonstration project, the company will quantitatively demonstrate the cost-reduction effects by introducing Infra-Sharing, as well as the reduction of electricity, aiming to utilize these effects in the development of 5G in countries around ASEAN that will proceed in the future.
The installation and operation of the demonstration project in Vietnam will be carried out by a JTOWER’s subsidiary in Vietnam, Southern Star Telecommunication Equipment Joint Stock Company, responsible for JTOWER’s Vietnamese business (Chairman and Representative Director: Satoshi Igarashi, Headquarters: Ho Chi Minh City, Vietnam)( “SPN”). Furthermore, KDDI Vietnam Corporation (General Director: Masaya Taguchi, Headquarters: Hanoi City, Vietnam) is responsible for the development and operation of applications for the provision of XR contents. In May 2022, the two companies signed an agreement concerning 5G radio wave measures at commercial facilities in Vietnam, the provision of XR solutions using 5G, and the collaboration in the demonstration project.

JTOWER will further refine the technology, service-quality, and business models that the company has cultivated in Japan’s high-quality telecommunications industry, which boasts the highest quality in the world, and contribute to the digitization of society under the vision of “Infra-Sharing Services from Japan Lead the World”.
