Doing a good job in the service guarantee for the 100th anniversary of the founding of the party is not only an important embodiment of the political character of China's iron tower, but also an important test of its combat effectiveness.

    Tower, also known as signal tower, is an important part of the infrastructure of telecom operators. In the early stage, in order to seize the market, the three operators continued to build base stations and other facilities, resulting in many problems such as low utilization of network resources and repeated investment. In 2014, under the leadership of SASAC, together with the Ministry of industry and information technology, the three operators held a coordination meeting to discuss how to make better use of resources and avoid excessive waste of resources. In this case, the Chinese iron tower came into being.

     China's steel transmission line tower, standing on the shoulders of giants, has developed rapidly. In just a few years, it has become the world's largest communication infrastructure operator, with 2.1 million communication iron towers and an asset scale of more than 330 billion yuan.

     More importantly, the iron tower model, born from sharing, relying on shared development and taking "sharing, competition and cooperation" as the core, has gradually realized the transformation from respective construction to overall planning and unified construction, and has developed rapidly in the direction of intensification, scale, specialization and efficiency. According to the data, by the end of 2020, China's iron towers had increased the total number of iron tower sites used by telecom enterprises by 1.3 times, helped build the world's largest and best quality 4G / 5G network, and significantly increased the sharing level of new iron towers from 14.3% to 80%, which is equivalent to building 840000 less iron towers, saving 150.5 billion yuan of industrial investment, and fully demonstrating the effectiveness of the reform.

     "China's iron towers shoulder important missions and responsibilities in the construction of new infrastructure." Liu Guofeng, deputy general manager of China iron tower Co., Ltd., said when attending the 2021 world telecommunication and information society day conference on May 17, 2021 that China iron tower is expanding the social sharing articles in an all-round way.
