C114讯 9月28日消息（张海龙）在2018年中国国际信息通信展览会同期举行的“深入推进网络提速降费 加快培育经济发展新动能”论坛上，中国铁塔副总经理顾晓敏表示，“一旦5G发牌后，中国铁塔在两到三年时间内就可助力运营商建设一张覆盖全国的5G网络，并通过充分利用的现有的站址和社会资源方式，大幅的降低投资成本。相信中国铁塔通过共享大幅降低投资，为绿色发展、美丽中国建设、网络强国以及提速降费做出应有的贡献。”

三年实现铁塔总量翻倍

顾晓敏介绍，中国铁塔的组建就是为了推进电信体制改革，解决通信重复建设的问题，从而实现让4G网络规模部署加速。

截止到目前，中国铁塔投资达到1500亿元，满足三家铁塔建设需求192万个，推动4G网络快速规模部署。2014年，三大运营商给中国铁塔注入144.2万个铁塔。自2015年运营以来，中国铁塔满足三大运营商塔类建设需求192万个，助力三大运营商站址规模接近翻番。

同时，高铁、地铁以及大型场馆的网络建设也是是由中国铁塔承担。三年多来，中国铁塔建设高铁项目77个，总覆盖里程13700公里，跟高铁建设基本实现同步规划、同步设计、同步施工，实现高开通之日便可实现网络信号全覆盖；完成地铁项目96个，总的覆盖里程达到2200公里。大型场馆3.9万个，覆盖超10亿平方米面积。在进行这些场景覆盖时，中国铁塔既节省建设成本，又提高网速，解决干扰问题，也提高了通信质量。

顾晓敏表示，“通过一家建设，三家使用，能共享、不新建，新建的进行共享方式，共享率由过去不足20%迅速提升了70%。这也得到了三大运营商的大力支持。中国铁塔与三家运营商的密切配合才有了今天70%以上的共享率。中国铁塔统计，铁塔重复建设减少64万个，节约投资1148亿元。”

同时，中国铁塔特别注意向西部地区倾斜，缩小数字鸿沟，在新建的铁塔站址当中农村及乡镇站址达到70%，三年多来总投资规模达到840亿元，这让西部12个省的站址增长高于全国平均水平。

经过三年运营，中国铁塔在今年8月8日成功在港交所主板上市，融资达到76亿美金，成为所有央企当中IPO规模最大的一次，也创下近三年融资规模新高。

创新发展降低行业总成本

在提升共享率的同时，中国铁塔还十分重视创新发展降低行业总成本。顾晓敏表示，经过三年多发展，中国铁塔探索形成了“共享竞合”的铁塔模式，有利支撑和保障了网络强国和提速降费的战略实施。通过共享利用、节约发展极大提升行业整体收益。三年多来，铁塔的共享折扣在不断优惠，今年初，中国铁塔又加大共享折扣，如加深比例的优惠，到今年初，三大运营商租金已经减少40亿元。

在创新上，中国铁塔采用一级架构，通过物联网方式对190万个站址进行管控，效率大大提升，同时节省了维护的成本。现在中国铁塔的15000名员工，人均管理站址数达到125座，远超于美国铁塔公司人均30座的水平。

中国铁塔通过电商化的采购，有效的来降低采购的成本。中国铁塔还通过精准的资产运营来提高效率效益，中国铁塔借鉴美国铁塔公司的管理模式，“一个站址，一张损益表”，从建设成本，最后得出利润，能够清楚明白的知道每个站最终的效益水平，有利于中国铁塔为三大运营商不断降低成本，从而实现租金下降。

同时，中国铁塔还通过共享社会资源降低建设成本。目前，中国铁塔跟两大电网公司，通过利用电力塔的合作，减少了投资，直接把降低的投资成本让利于三大运营商。中国铁塔跟公路、公安合作，把路灯杆资源共享给三大运营商，利用社会塔资源降低投资成本，最终给三大运营商实实在在的优惠。

面向5G未来，中国铁塔将持续的深化共享，实现5G又快又好建设。顾晓敏表示，“一旦5G发牌后，中国铁塔在两到三年时间内就可助力运营商建设一张覆盖全国的5G网络，并通过充分利用的现有的站址和社会资源方式，大幅的降低投资成本。”

C114 News September 28 (Zhang Hailong) In the same period of the China International Information and Communication Exhibition held in 2018 "in-depth promotion of network speed-up and reduction of fees to accelerate the cultivation of new momentum of economic development" forum, China's deputy general manager Gu Xiaomin said, "once the 5G license, China's iron tower in two to three years to help the operation of the time. Businessmen build a nationwide 5G network, and greatly reduce investment costs by making full use of existing sites and social resources. It is believed that the China Tower will make due contributions to green development, beautiful China's construction, network power and speed up and reduce fees by sharply reducing investment.

Three years to double the total iron tower

Gu Xiaomin introduced that the establishment of China Tower is to promote the reform of the telecommunications system, to solve the problem of repeated construction of telecommunications, so as to speed up the deployment of 4G network scale.

Up to now, China's investment in iron towers has reached 150 billion yuan, meeting the construction needs of three towers of 1.92 million, and promoting the rapid deployment of 4G networks on a large scale. In 2014, the three operators injected 1 million 442 thousand towers into China's tower. Since its operation in 2015, China's towers have met the needs of 1.92 million towers for the three operators, helping nearly double the size of the three operators'stations.

At the same time, the network construction of high-speed rail, subway and large venues is also undertaken by the Chinese tower. Over the past three years, China has built 77 high-speed railway projects with a total coverage of 13700 km, and basically achieved synchronous planning, design and construction with the construction of high-speed railway, so as to achieve full coverage of network signals on the day of high-speed opening; 96 metro projects have been completed, with a total coverage of 2200 km. There are 39 thousand large venues covering over 1 billion square meters.  While covering these scenarios, the China Tower not only saves construction costs, but also increases network speed, solves interference problems and improves communication quality.

Gu Xiaomin said, "through the construction of one, three use, can share, not new, new way of sharing, sharing rate from less than 20% in the past rapidly increased by 70%.  This has also been strongly supported by the three operators. The close cooperation between China's tower and three operators has gained more than 70% share today.  Statistics of China's Tower show that the tower's redundant construction has been reduced by 640 thousand and the investment has been saved by 114 billion 800 million yuan.

At the same time, China's iron tower pays special attention to tilting to the western region and narrowing the digital divide. Among the new iron tower sites, 70% of the rural and township stations are located, and the total investment in the past three years has reached 84 billion yuan, which makes the growth of the stations in 12 western provinces higher than the National average.

After three years of operation, the China Tower successfully listed on the main board of the Hong Kong Stock Exchange on August 8 this year, raising $7.6 billion, making it the largest IPO of all central enterprises, and a record high in financing scale in the past three years.

Innovative development to reduce total industry cost

While enhancing the sharing rate, the Chinese tower also attaches great importance to innovation and development, reducing the total cost of the industry. Gu Xiaomin said that after more than three years of development, China's iron tower has explored and formed a "shared competing" iron tower model, which is conducive to supporting and ensuring the implementation of the strategy of network power and accelerated fee reduction. Through sharing, utilization and saving development, we can greatly enhance the overall revenue of the industry. Shared discounts for the towers have been on the rise for more than three years. Earlier this year, China's towers increased their share discounts, such as deepening the proportion of discounts. By the beginning of this year, the three operators'rents had been reduced by 4 billion yuan.

Innovatively, the China Tower uses a first-class structure to manage and control 1.9 million stations through the Internet of Things, which greatly improves efficiency and saves maintenance costs. At present, the number of management stations per capita for the 15,000 employees of the China Tower has reached 125, far exceeding the level of 30 per capita of the United States Tower Corporation.

Through the procurement of electricity suppliers, the Chinese tower effectively reduces the cost of procurement. China Tower also improves efficiency through precise asset operation. China Tower draws lessons from American Tower Company's management model of "one site, one profit and loss statement". From the construction cost, we can get the profit finally. We can clearly know the final benefit level of each station, which is beneficial for China Tower to be the three largest operators. Reduce costs and reduce rents.

At the same time, the Chinese tower also reduces the construction cost through sharing social resources. At present, China Tower and the two major power grid companies, through the use of power tower cooperation, reduce investment, directly reduce the cost of investment to benefit the three major operators. China Tower cooperates with highway and public security to share the lamppost resources to the three major operators, and uses the social tower resources to reduce investment costs, and finally gives the three operators substantial preferential treatment.

Facing the future of 5G, the Chinese tower will continue to deepen sharing and realize 5G construction quickly and well. "Once the 5G license is issued, the tower will help operators build a nationwide 5G network in two to three years and substantially reduce investment costs by making full use of existing sites and social resources," Gu said.
