5G Base Station Architecture
Uncover the intricate world of 5G Base Station Architecture, from gNode B to NGAP signaling. Dive into flexible network deployment options.
5G base stations operate by using multiple input and multiple output (MIMO) antennas to send and receive more data simultaneously compared to previous generations of mobile networks. They are designed to handle the increased data traffic and provide higher speeds by operating in higher frequency bands, such as the millimeter-wave spectrum.
There are great differences between 5G and 4G base stations in a number of areas, which together empower 5G to offer better speeds, lower latency, and higher connection density. The differences are reflected in the following areas: 5G base stations adopt a more flexible architecture that supports network slicing and virtualization technologies.
The differences are reflected in the following areas: 5G base stations adopt a more flexible architecture that supports network slicing and virtualization technologies. Network slicing can make the network dynamically adjust resource allocation according to the demands of different services, improving the flexibility and efficiency of the network.
While 4G base stations typically have fewer antenna ports, 5G base stations support massive MIMO technology and are capable of having up to 100 ports. That is to say, with the same array, more antennas could be installed and more users could be served simultaneously with increased network capacity.
Compared with 4G networks, 5G not only increases power consumption by more than three times, but also doubles the demand for 5G base stations due to the attenuation of coverage. Therefore, for operators, 5G base stations The high power consumption has even become the primary reason for restricting 5G network construction.
From the perspective of equipment architecture, 5G base stations can be divided into different architectures such as BBU-AAU, CU-DU-AAU, BBU-RRU-Antenna, CU-DU-RRU-Antenna, and integrated gNB.
