Part 3 Question-and-answer session
In the question-and-answer session, Vice President Uchida, concomitantly Executive Director of the Technology Sector, and other panelists answered the participants' questions.
- I reckon that more base stations will be established for 5G. I would like to know about the operating framework and costs. Also, how do you see the virtualization technology that Rakuten is planning to implement?
In preparation for the full release of 5G, we are promoting the standardization of currently segmented operations as well as the optimization of processes, which is one part of our automation efforts. The increase in the number of base stations will not lead to a simple proportional increase in operating costs.
We believe that the virtualization technology is in line with the modern trend, but will have a number of issues in the attempt to provide a comfortable communications environment. KDDI currently has more than 40 million customers using our services, and we are working meticulously to be able to respond to failures and sudden surges in traffic.
- The international center for operation and maintenance (GNOC) is based in Vietnam. What is the reason for having a center in Vietnam?
We have many personal and corporate customers in Southeast Asia, which is why we wanted to establish an operation and maintenance base in this area. With all things considered around the establishment of a base in Southeast Asia, we decided on Vietnam.
- What is the difference in the operation framework between the IoT global platform and the current network?
The IoT global platform will be an intricate combination of networks around the world. A dedicated operation framework is established in Shinjuku, Tokyo, to promote coordination with overseas partners according the situation in each region.
- I would like to know the scale of the staff operating and maintaining the KDDI network. Additionally, please elaborate on the current competitive environment for the submarine cable business.
While we cannot disclose the specific number, we can say that the staff is made up of a combination of contractors, business partners, and regular KDDI employees and that staffing is revised according to the workload.
Enterprises from different industries entered the submarine cable business for investment purposes, anticipating an explosive increase in demand for traffic. However, nowadays, with improved methods of ensuring sufficient communication capacity, even with some OTT businesses entering the market to ensure sufficient capacity for traffic, the competitive environment remains stable.
