Japan had over 100,000 active 5G base stations by 2023 Japan's 5G network is expanding rapidly, with over 100,000 active base stations by 2023. The country has taken a strategic approach, focusing on major urban centers first and gradually expanding to rural areas.
In data collected between July 2022 and June 2024, China was reported to have had around 3.5 million 5G base stations installed across the country, with Chinese mobile operators investing heavily in 5G infrastructure. By comparison, the European Union had around 460,000 thousand base stations, while the United States had approximately 175,000.
They help fill coverage gaps, improve network reliability, and handle high data traffic. In cities, more than 60% of 5G base stations are small cells, placed on rooftops, lampposts, and building facades. These mini base stations are crucial for delivering consistent 5G speeds in crowded areas like stadiums, shopping malls, and business districts.
The 5G baseband unit is responsible for NR baseband protocol processing, including the entire user plane (UP) and control plane (CP) protocol processing functions, and provides the backhaul interface (NG interface) with the core network and the interconnection interface between base stations (Xn interface ).
In this paper, we thoroughly study the base station control problem in 5G ultra-dense networks and propose an innovative MAPPO algorithm. The algorithm significantly reduces the overall power consumption of the system by optimizing inter-base station collaboration and interference management while guaranteeing user QoS.
The limited penetration capability of millimeter waves necessitates the deployment of significantly more 5G base stations (the next generation Node B, gNB) than their 4G counterparts to ensure network coverage . Notably, the power consumption of a gNB is very high, up to 3–4 times of the power consumption of a 4G base stations (BSs).
However, the selection of 5G base station locations is also influenced by local terrain and population distribution, and obstacles such as streets, buildings, and trees can significantly impact signal propagation.
Comparison results of 5G base station optimization in general urban areas. As shown in Table 11, the algorithm proposed in this topic reduces the site construction cost by at least 13 %, improves the coverage by at least 5.4 %, and reduces the number of base stations by at least 17.6 % compared to other algorithms.
Meanwhile, mobile networks offering speeds of 300 Mbps were available to 60% of households in about 1% of Finland's land area. 5G base stations, which numbered almost 3,000 in total, could be found in 109 municipalities. At the same time, 100 Mbps 4G networks covered 17% of the land area and 93% of households.
Major road networks are also among the first areas to receive new mobile network technologies. In late 2020, 100 Mbps 5G networks covered 17% of Finland's main roads and highways and 18% of the railway network, while 100 Mbps 4G coverage was available on 57% of both networks.
The country has a competitive telecommunications market dominated by three key players: Elisa, Telia, and DNA. Elisa held the largest share of revenue from fixed-line, mobile, TV, and radio operations, at 37 percent in 2023. Telia Finland, part of Telia Company since 2017, followed closely, while DNA held 23 percent of the market.
The 5G market in Finland is dominated by three key players, Elisa, Telia, and DNA. The coverage of 5G in the country is challenged by a vast contrast between urban and rural areas.
5G networks divide coverage areas into smaller zones called cells, enabling devices to connect to local base stations via radio. Each station connects to the broader telephone network and the Internet through high-speed optical fiber or wireless backhaul.
Major suppliers of 5G radio and core systems included Altiostar, Cisco Systems, Datang Telecom/Fiberhome, Ericsson, Huawei, Nokia, Qualcomm, Samsung, and ZTE. Huawei was estimated to hold about 70 percent of global 5G base stations by 2023.

The marketing of non-5G services refers to the promotion of enhanced 4G networks that are presented as precursors or equivalents to 5G. Some mobile network operators marketed upgraded 4G technologies using terms that suggested 5G capability.
