In addition to considering ways to develop new indoor and outdoor networks and the efficient use of existing towers, the companies will develop an efficient 5G network which will lead to the reduction of capital investments and other costs, power consumption, and installation spaces. Going forward, the companies will aim to realize the early expansion of 5G coverage by promoting Infra-Sharing.
