JTOWER Inc. and KDDI Corporation signed the memorandum on joint study aimed to develop sustainable telecommunications infrastructures in the society with declining population. The two companies will study the measures such as consolidation of telecommunications towers through tower sharing and the replacement of indoor 4G facilities which need to be upgraded with Infra-Sharing facilities, aiming for stable operation and efficient maintenance and management of telecommunications infrastructures. In this joint study, will consider the replacement of KDDI's facilities which need to be upgraded with JTOWER's Indoor Infra-Sharing facilities.

As for outdoors, will study the consolidation of telecommunications towers through tower sharing. In particular, the consolidation of telecommunications towers owned by mobile network operators is expected to not only contribute to the reduction of maintenance and replacement costs, but also to be an effective way of addressing social issues in a declining population society. Will verify and evaluate the economic efficiency and effectiveness of indoor and outdoor Infra-Sharing aiming to realize the full-scale deployment.

JTOWER and KDDI will continue to strengthen collaboration and work to resolve social issues through the promotion of Infra-Sharing.
