Do 5G communication base stations have multi-objective cooperative optimization?
This paper develops a method to consider the multi-objective cooperative optimization operation of 5G communication base stations and Active Distribution Network (ADN) and constructs a description model for the operational flexibility of 5G communication base stations.
Why are micro base stations important in 5G planning?
Micro base stations, on the other hand, are smaller and more flexible, allowing them to supplement the peripheral communication that cannot be covered by macro stations, thereby improving communication quality and capacity. Therefore, micro stations play a critical role in 5G planning.
How much power does a micro base station use?
The power consumption of a single macro base station is approximately 5 kW, whereas a Pico Cell requires only about 10 W (Bolla et al., 2012; Deruyck et al., 2014; Hu & Yi, 2014). Deploying multiple micro base stations to cover the blind spots of a macro base station will reduce power consumption during operation, thereby reducing carbon emissions.
