 Energy consumption has become a barrier to the popularization of 5g, and the three operators will close 5g base stations in a specific period of time


There are many reasons for the excessive power consumption of 5g base station. First of all, 5g has a large bandwidth. The wireless data rate of 5g is 100 times that of 4G, and more data can be transmitted in the same time. According to the law of conservation of energy, this will inevitably lead to a significant increase in the power consumption of 5g base station compared with 4G.

Secondly, the 5g frequency band is too high. At present, the mainstream frequency band of 5g is 3.5GHz, while the mainstream frequency band of 4G is 1.8GHz, and 2G is as low as 900MHz. It is known by the industry that the higher the frequency band, the smaller the coverage of base station, which leads to the construction density of 5g base station is much higher than that of 2G and 4G. It is generally believed that the density of 5g base station is at least 1.5 times higher than that of 4G.

As a result, the construction cost of 5g network is much higher than that of 4G network, and the operation cost of 5g is too high. The investment cost and operation cost of 5g are too high, which brings great pressure to operators.

The construction cost and operation cost of 5g network have increased significantly, but the profit of operators is declining. The performance in 2019 shows that China Mobiles net profit has decreased by 9.5% year-on-year, while that of China Telecom has decreased by 3.3%. Although China Unicom has made a rise in net profit, its net profit is only one-third of that of China Mobile.

The net profit of China Mobile and China Telecom has declined, and the net profit margin of China Unicom is too low, which makes the three operators have to take measures to control the cost. Judging from the current choices of the three operators, they clearly believe that the energy consumption of 5g base station is one of the costs that should be saved.

5g mobile phone market also showed some unfavorable signs. The sales volume of 5g mobile phones in July was lower than that in June, which showed that although the price of 5g mobile phones was falling rapidly, it failed to effectively promote the sales of 5g mobile phones. Users hesitated to purchase 5g mobile phones.

All of these conditions have an impact on the development of 5g, and energy consumption is undoubtedly a major factor affecting the development of 5g. 5g consumes a lot of energy, leading to the construction progress of 5g base stations of the three operators is far lower than that of 4G. Operators choice of closing 5g base stations in idle hours will affect consumers choice of 5g services.
