TOKYO, JAPAN, November 22, 2021 --- JTOWER Inc. ("JTOWER") and NTT DOCOMO, INC. ("DOCOMO") jointly announced today that they have decided to form a capital and business alliance ("the Capital and Business Alliance") with the aim of strengthening collaboration in the use of Infra-Sharing.

DOCOMO plans to acquire part of JTOWER shares held by NIPPON TELEGRAPH AND TELEPHONE CORPORATION and become a shareholder with 2.5% voting rights in the future.

DOCOMO started using the JTOWER's Infra-Sharing solution (IBS*1) for its 4G network in 2016 and has expanded the use of the solution nationwide. Furthermore, from October 2020, the company started using 5G IBS at the time JTOWER installed 5G IBS in the Tokyo Metropolitan Government as the first 5G Infra-Sharing in Japan, and also began using Smart Poles*2 in the Nishi-Shinjuku area of Tokyo. Both companies have continued to promote the use of Infra-Sharing through these activities.

JTOWER and DOCOMO will use this alliance as an opportunity to strengthen collaboration. 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.

2. Smart Pole: A multi-functional pole with 5G base stations, Wi-Fi, surveillance camera , digital signage, etc.
