[What is Infrastructure Sharing]
It is possible to share network facilities, which were previously developed independently by each mobile carrier, through infrastructure sharing. Because the costs for equipment, operation, and maintenance can be reduced compared to independent development by mobile carriers, a more efficient network development can be realized. Furthermore, since power consumption, materials, and the number of construction times can be reduced, it also leads to a lower environmental impact.
[About the Indoor Infrastructure Sharing Solution]
In large buildings with a total floor area exceeding 10,000 square meters, there is a high necessity to prepare an indoor mobile signal environment. By utilizing infrastructure sharing for indoor signal environment development, it provides benefits such as space saving, electricity cost reduction, and single point of contact for real estate businesses; reduction of capital investment and operational costs for mobile carriers; and satisfaction improvement through better communication environments for mobile users.
