Discussion on the coverage of 5G antenna

News 1946

With the rapid development of 5G technology, people have a high degree of concern about its coverage range, signal stability, and transmission speed. In particular, the coverage range of 5G antennas is directly related to the accessibility of network services and user experience. Today, we will delve into the coverage range of 5G antennas.

The main technical differences between 5G antennas and 4G antennas. The higher frequency band used in 5G means that the transmission distance of 5G signals is shorter than that of 4G signals, and the penetration ability is also relatively weak. 5G networks require denser base station deployments and more advanced antenna technology to ensure coverage.

The factors that affect the coverage area of 5G antennas mainly include the following:

1. Frequency band selection: 5G uses two main frequency bands: millimeter wave (mmWave) and sub-6GHz. The millimeter wave band can provide higher data transmission rates, but has a short propagation distance and is easily blocked by obstacles such as buildings; while the sub-6GHz band has a wide coverage area, but the rate is relatively low. The choice of different frequency bands has a direct impact on coverage.

2. Antenna technology: 5G uses Massive MIMO (massive multiple input multiple output) technology, which can serve more users at the same time and improve spectral efficiency. At the same time, beamforming technology can concentrate signal energy to send it in a specific direction, enhancing the strength of the received signal and thus expanding the effective coverage area.

3. Base station density: Due to the attenuation characteristics of 5G signals, to achieve widespread coverage, it is necessary to increase the number of base stations. The smaller the distance between base stations, the fewer blind areas there are for coverage, and the better the user experience.

Environmental factors: High-rise buildings in cities, topographical relief in mountainous areas, and other natural and man-made obstacles can affect the propagation of 5G signals. Therefore, the actual coverage range varies depending on regional differences.

5. Terminal devices: 5G devices (such as mobile phones, tablets, etc.) in the hands of users can also affect the coverage effect. The higher the receiving sensitivity of the device, the better it can maintain connectivity in a weak signal environment.

After understanding these factors, we can draw some conclusions about the coverage area of 5G antennas:

- In urban centers and densely populated areas, the coverage of 5G will be more ideal due to the dense deployment of base stations. However, in suburban or rural areas, due to the large spacing between base stations, uneven coverage may occur.

- In indoor environments, especially in large buildings, signal coverage needs to be enhanced through indoor distribution systems (such as small base stations, repeaters, etc.).

- In the application of high-frequency millimeter waves, straight-line line-of-sight propagation is particularly important, so it is necessary to consider the layout of buildings and obstacles and plan the location and direction of antennas reasonably.
