Introduction: 5G is the commanding height of the new round of information technology revolution, and the layout of 5G must first be constructed for large-scale communication base stations. Adding a communication base station to the existing power tower (rod) to save infrastructure resources is the original intention of this "shared movement."
"No. 12 shared iron tower, the power line is in good condition, and the communication base station is not disturbed." At the beginning of this month, on the 12th tower of the 110 kilovolt car line 2 in Yichang City, Hubei Province, workers installed mobile communication on the transmission tower. Carrier's 5G test base station.
Today, a "shared tower" like this is blossoming everywhere. 5G is the commanding height of the new round of information technology revolution, and the layout of 5G first requires the construction of large-scale communication base stations. Adding a communication base station to the existing power tower (rod) to save infrastructure resources is the original intention of this "shared movement."
On July 18, 2014, China Railway Tower Co., Ltd. (hereinafter referred to as China Tower), initiated by China Mobile, China Unicom and China Telecom, was listed. Not long ago, the company submitted a listing application to the Hong Kong Stock Exchange. The "Iron Tower for Sharing" has ushered in a new stage of development after more than three years of establishment.
Sharing cooperation, power tower resources can meet 5G layout needs
The frequent landing of the “Twin Tower Sharing†initiative has been interpreted as the key action of China's reserve 5G site resources. The application for the listing of China Tower pointed out that the development of new technologies has spawned a new round of large-scale networking needs. By 2022, the number of 5G base stations in the Chinese market is expected to reach approximately 2.432 million.
Previously, when signing with State Grid Co., Ltd. (hereinafter referred to as State Grid) and China Southern Power Grid Co., Ltd. (hereinafter referred to as China Southern Power Grid), China Railway Tower Chairman, Party Secretary and General Manager Qi Jilu said that the number of 5G base stations in the future will be Several times of 4G, the grid company has tens of millions of tower resources, and a considerable part can meet the requirements of communication equipment mounting. The cooperation between the two parties can quickly meet the needs of 5G network deployment.
Lu Tingjie, a professor and doctoral supervisor at the School of Economics and Management of Beijing University of Posts and Telecommunications, said: "5G construction requires a large amount of tower resources. If new towers are built according to traditional practices, it is very likely that there will be a phenomenon of pavement poles and chaos. Tower (rod), and supporting power security, which provides very good resource conditions for 5G deployment. In the future, the gradual popularization of 'shared towers' will have a profound impact on 5G."
With the addition of more “shared towersâ€, problems such as weak wireless signal coverage in some areas of communication infrastructure construction will also be effectively solved.
Power tower to change communication tower, saving land and reducing investment cost
As the State Grid and China Southern Power Grid signed a strategic cooperation agreement with China Tower, the “Power Tower†and “Communication Tower†began to be openly shared across the country.
According to the data provided by China Tower, at present, China has built 49 large base stations and 356 small and micro stations using 110 kV, 220 kV and 380 kV high-voltage power towers. The sharing rate of new communication towers nationwide is 14.3%. It quickly rose to 70.4%, which is equivalent to the construction of 603,000 towers and the investment of 107.3 billion yuan.
Li Qingkui, chairman and party secretary of China Southern Power Grid, said that “shared towers†​​can improve resource utilization and realize the extension of power towers for power companies. For social public resources, “one tower (pole) can be used effectively†Land resources and avoid redundant construction.
According to the statistics of China Railway Tower, the average cost of building a ground communication tower is 142,000 yuan, covering an area of ​​about 30 square meters. According to the preliminary calculation of China Southern Power Grid, Yunnan Power Grid, which is the first to promote “shared towersâ€, can share 5,308 towers between 2018 and 2020, which will save nearly 55,700 square meters of land resources and reduce the redundant construction cost by 319 million yuan.
There is no precedent in China, and the opening of the tower resources requires government guidance.
There is no precedent in China for the installation of communication base station equipment on power towers (rods), especially high-voltage transmission towers. Therefore, whether the "shared tower" has potential safety hazards, whether telecommunications and communication services affect each other, etc. become a social concern.
According to the technical experts of Yunnan Power Grid: "The electromagnetic waves on the power tower have no effect on the communication base station, and the communication base station has no impact on the power consumption of the power tower after the power tower is attached."
The relevant person in charge of Yunnan Power Grid stated that the power tower is a high-rise structure and the state has strict grounding requirements for such facilities. In addition, considering the safety factor, in the design process, the base station's abutment position can ensure that there is no electric shock accident and that the equipment can reach the communication requirements.
“'Twin Tower Sharing' breaks the barriers of the two industries of telecommunications and telecommunications. This model of revitalizing stock resources and doing 'subtraction' has realized resource sharing and belongs to the real shared economy.†Lu Tingjie suggested that relevant government departments should introduce The policy documents clearly support, actively guide, and help coordinate the open sharing and integration of public resources of existing social towers.
