Huawei, Ericsson, and Nokia collectively hold ~80% of the worldwide 4G/5G base station market, while NEC and Fujitsu together hold under 1.5% global market share. That leaves Japan's network equipment vendors structurally disadvantaged on both scale and pricing power.
1. Introduction In recent years, with the widespread deployment of 5 G technology, global communication data traffic has experienced rapid growth, leading to an increase in the construction and operational scale of communication base stations (Dangi et al., 2021, Ahmad et al., 2024).
Model of Base Station Power System The key equipment in 5G base stations are the baseband unit (BBU) and active antenna unit (AAU), both of which are direct current loads. The power of AAU contributes to roughly 80% of the overall communication system power and is highly dependent on the communication volume .
However, the construction and operation of 5 G base stations face significant energy consumption challenges. Under full-load conditions, the power consumption of 5 G base stations is approximately 3–4 times that of 4 G base stations, which has a notable impact on energy consumption and environmental concerns (Zhang et al., 2020, Feng et al., 2012).
In today''s 5G era, the energy efficiency (EE) of cellular base stations is crucial for sustainable communication. Recognizing this, Mobile Network Operators are actively prioritizing EE for both network maintenance and
