At the infrastructure level, energy, power, transportation and other infrastructure, urban and industrial infrastructure will gradually become the main battlefield of 5g construction in the future.
The investment cost of 5g network construction will be much higher than that of 4G era. Wu Hequan, academician of the Chinese Academy of engineering, said that China's 4G network construction took six to seven years, with an investment of about 700 billion yuan to 800 billion yuan. 5g construction cycle may be longer than 4G. If the annual investment intensity remains unchanged, after 8 to 10 years, the investment is more than 100 million yuan, and 5g network can be built.
According to the calculation by the analysis department of communication industry of China construction investment, it is predicted that the number of 5g base stations will be twice that of 4G in the future, and the investment of operators in 5g network construction may reach 1.23 trillion yuan, an increase of 68% over 4G investment.
So, where is the cost of 5g network construction higher than 4G network construction? Wang Zhiqin, vice president of China Academy of information and communication, said that the frequency of 3.5GHz and 4.9ghz obtained by the three major operators will double the number of base stations compared with 1.8GHz in the 4G era. 5g will not only cover mobile Internet scenarios, but also further deepen to industrial application scenarios such as factories. The number of base stations has increased to some extent.
5g bandwidth is about 5 times that of 4G, and the application of large-scale antenna technology will bring a significant increase in energy consumption. Yan Binfeng, director of the technical committee of China Unicom Research Institute, said that the electricity charge for 5g equipment is expected to be more than three times that of 4G. In the past two years, China's electricity price has been reduced by 10% respectively. If the electricity price is reduced from 10% discount to 30% discount in 2020, it is expected to reduce the electricity price by 70 billion yuan.
In addition, 5g network construction also faces the problems of difficulty and expensive admission. Dou Li, President of China Tower Research Institute, said that the indoor distribution system of 5g network is mostly reconstructed in 2G, 3G and 4G stock scenarios, but there are deficiencies in the appropriate installation location and computer room, unlike a series of measures that can be taken for new facilities. In addition, there are also problems of high cost and difficulty in admission.
In the face of high construction costs, operators are in short supply. On the one hand, China's 4G network investment has not yet recovered its cost; on the other hand, in the first half of 2019, the revenue of the three major operators declined collectively, and the investment pressure increased.
On September 9 this year, China Unicom and China Telecom signed the 5g Network Co Construction and sharing framework cooperation agreement. The two operators took out different 5g frequencies allocated by the government to jointly build an access network. This will help to reduce the cost of network construction and operation and maintenance.
According to the previously disclosed plan, in 2019,China MobileMore than 50000 base stations are built in more than 50 cities, 40000 base stations are built in 50 cities by China Telecom, and 40000 base stations are built in more than 40 cities by China Unicom. By 2020, there will be large-scale investment in 5g network from three major telecom operators.
Electric charge is the most expensive part in 5g operation. At present, Shanxi and Jiangxi give support and preferential treatment to commercial electric power operation. Wang Zhiqin said that the power consumption of the base station is relatively large. It is suggested that 5g base station should use direct power supply as much as possible to reduce the power supply mode. After calculation, the price of direct power supply mode will be half lower than that of power supply mode. At the same time, he hopes that the government will have some price concessions in power consumption.
Shu Huaying, a professor at Beijing University of Posts and telecommunications, suggested opening up public resources such as buildings and public land to ensure 5g network construction. In addition, it is suggested to establish 5g investment and construction fund to promote 5g infrastructure construction by means of financial means and low interest rate.
