It consists of antennas, transceivers, and digital processing units that transmit and receive radio signals between user devices and the network. 5G base stations operate on various frequency bands, including sub-6 GHz and mmWave, to deliver ultra-low latency, high data throughput, and enhanced capacity.
5G technology is revolutionizing connectivity, and the manufacturers of 5G equipment are leading this transformation. From modems and base stations to RAN, antenna arrays, and core networks, these companies are providing cutting-edge solutions. Leading vendors are offering innovative products to enhance network speed, coverage, and efficiency.
The 5G Radio Access Network (RAN) is the interface between user devices and the 5G core network. It comprises base stations and small cells that manage radio communications, enabling ultra-fast data transfer and low-latency connections.
The 5G core supports advanced features such as network slicing, which allows the creation of virtual networks tailored for specific applications like IoT, AR/VR, or autonomous vehicles. It also enhances security, reliability, and energy efficiency, enabling seamless connectivity for billions of devices globally.
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.
In 5G, base stations are known as gNB, where the “g” stands for next Generation. The Mobile Core is a bundle of functionality (conventionally packaged as one or more devices) that serves several purposes. Provides Internet (IP) connectivity for both data and voice services. Ensures this connectivity fulfills the promised QoS requirements.
5G Base Stations: Compared to 4G base stations, 5G brings higher data throughput and power density, significantly increasing heat generation. Therefore, the performance requirements for thermal materials are much higher. ● Small/Micro Base Stations: These base stations are compact, with limited space, making thermal design more challenging.
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.
2027 master plan – a second 'Set Sail' 5G expansion plan aims for 85% 5G penetration and 75% of network traffic on 5G. The total number of 5G base stations in China reached 4.486 million as of the end of May (2025), according to data released by the country's Ministry of Industry and Information Technology (MIIT).
Mobile operators in China are ramping up 5G and 5G-A rollouts, with the former now at 4.5 million cell sites and the latter in 300 cities; a new 2027 roadmap will see 75% of mobile data in the country on 5G networks. 5G on 5M sites – China has over 4.486 million 5G sites; 5G now comprises more than 35% of total mobile base stations.
China Mobile, the world's largest mobile carrier in terms of subscribers, had previously outlined plans to deploy 340,000 additional 5G base stations in 2025. With these new 5G deployments, China Mobile's total 5G base stations will reach nearly 2.8 million by the end of 2025.
