    China Tower: Deepen resource sharing to meet the deployment of 5G rapid economy scale

    作为移动通信基础设施建设运营的“国家队”“主力军”,中国铁塔成立五年多来不断深化共享,全力支撑行业快速经济地建设移动宽带网络,取得显著成效。截至目前,中国铁塔累计完成铁塔基站建设项目197.9万个,承建室内分布总覆盖面积超19亿平方米,覆盖高铁总里程超1.8万公里、地铁总里程超3100公里,三家电信企业使用的站址数量较中国铁塔成立之初翻了一倍;新建铁塔共享率从14%提升到近80%,相当于少建铁塔72万座,节约了约1300亿元投资和3.7万亩土地等社会资源,促进了城市美化和两型社会建设。
    As the "national team" and "main force" of mobile communication infrastructure construction operation, China Tower has been deepening sharing for more than five years, and has made great efforts to support the rapid economic construction of mobile broadband networks in the industry, with remarkable results. Up to now, China's tower has completed a total of 1.979 million station construction projects, the total indoor distribution area of more than 1.9 billion square meters, covering the total mileage of high-speed rail more than 18,000 kilometers, the total mileage of the subway more than 3100 kilometers. The number of three telecommunications enterprises used more than doubled the number of sites used at the beginning of the establishment of china's tower. The sharing rate of new towers has been increased from 14% to nearly 80%, which is equivalent to 720,000 fewer construction towers, saving about 130 billion yuan in investment and 37,000 mu of land and other social resources, and promoting urban beautification and two-type social construction.

    5G与4G相比,频率高、设备功耗大,要实现同等的网络覆盖质量,基站数量将是4G的数倍,对网络规划、基站选址、设施建设、电力保障等都提出了更高要求,投资规模十分巨大,还面临密集站址对城市市容景观带来影响的问题。
    Compared with 4G, the frequency is high and the equipment power consumption is large. To achieve the same network coverage quality, the number of base stations will be several times of 4G. The network planning, base station location, facilities construction, power security, etc. will put forward higher requirements. The scale of investment is very large, but also face the problem of dense site impact on the urban landscape.

    室内是5G的主要应用场景,室内场景的应用占比越来越高。据统计,4G业务中有70%的应用发生在室内场景,业界预测未来5G超过85%的业务将发生在室内场景,无源室分将是5G室内覆盖的主流方案。目前,在2G/3G/4G网络中,90%以上的室内覆盖都采用无源室分技术,建设成本和后期运营维护成本都更低。面向5G室分共享,中国铁塔提供了完善的低成本无源室分共享方案,支持三家电信企业2G/3G/4G/5G全频段共享接入,适应楼宇与隧道、新建与改造全场景需求,可最大化节省三家电信企业5G室分建设成本。以地铁场景为例,地铁是5G室内覆盖的首发场景,中国铁塔联合三家电信企业和产业链合作伙伴,在郑州、石家庄、济南地铁隧道开展了5G覆盖试验,采用了中国铁塔研发的5G新型漏缆等创新产品,3.5GHz高频段覆盖距离可达600米以上,在国际上率先实现了5G高频段与现有4G同等覆盖距离,实现了4G、5G信源同点位安装,大幅减少5G基站信源投资和配套投资。
    Indoor is the main application scene of 5G, indoor scene application proportion is getting higher and higher. According to statistics, 70% of the applications in 4G business occur in indoor scenes, the industry predicts that the future 5G more than 85% of the business will occur in the indoor scene, passive room division will be 5G indoor coverage of the mainstream program. At present, in 2G/3G/4G network, more than 90% of indoor coverage is using passive room separation technology, construction costs and post-operation maintenance costs are lower. For 5G room sharing, China Tower provides a perfect low-cost passive room sharing scheme, supporting three telecommunications enterprises 2G/3G/4G/5G full band sharing access, adapting to building and tunnel, new construction and transformation of the full scene needs, can maximize the savings of three telecommunications enterprises 5G room sub-construction costs. Take the subway scene as an example, the subway is the first scene of 5G indoor coverage, China Tower joint three telecommunications enterprises and industrial chain partners, in Zhengzhou, Shijiazhuang, Jinan subway tunnel carried out 5G coverage test, the use of China Tower research and development of 5G new leakage cable and other innovative products, 3.5GHz high frequency band coverage distance of up to 600 meters, the first in the international community to achieve 5G high frequency band and the existing 4G equivalent coverage distance, to achieve 4G, 5G source of the same point installation, significantly reduce the 5G base station source investment and supporting investment. 

    针对5G设备功耗大等难题,中国铁塔坚持创新驱动发展,提出市电削峰等电源配套解决方案,对于电力引入费高、引电周期长的部分站点可实现市电免改造,有效降低了改造成本,缩短了建设周期。中国铁塔还推出新型基站用开关电源及蓄电池合路器产品,增强5G电源建设的灵活性和扩展性,可实现按需扩容。
    In view of the difficult problems such as the power consumption of 5G equipments, China's tower adheres to the innovation-driven development, puts forward power supply supporting solutions such as electric cutting peak, and can realize the conversion of electricity-free some sites with high power introduction and long power generation cycle, effectively reducing the cost of transformation and shortening the construction cycle.
    China Tower also introduced a new type of base station switching power supply and battery joint ertoum products, to enhance the 5G power supply construction flexibility and expansion, can achieve on-demand expansion.
