Abstract
Millimeter-wave (mmW) communication has great potential in expanding channel capacity, increasing transmission rates, enhancing anti-interference capabilities, and reducing delay. Therefore, it has been the subject of much attention and research, and it has been adopted as a core technology of 5G. So far, researchers have experimentally verified that high throughput can be achieved with 5G mmWs. However, compared to those of traditional medium- and low-frequency base stations, the propagation characteristics of mmWs have caused link instability and interference problems in large-scale networks, which brings new challenges to the industrial capability of the mmW band and puts forward new requirements for the performance evaluation of mmW base stations. In this paper, based on the signal characteristics of the mmW band and applicable scenarios of mmW base stations, a performance evaluation method for mmW base stations in commercial networks is comprehensively presented. Using the evaluation system described in this paper, we conduct measurements on commercial mmW base stations, evaluate the performance of these stations, and provide comprehensive guidance for their design and actual deployment.

Summary
As an important part of the global fifth-generation (5G) spectrum strategy, the millimeter-wave (mmW) band has the advantages of large bandwidth and low delay and is an important future direction for the development of mobile communication technology [1], [2]. The deployment of mmW base stations should focus on short-range hotspot coverage to provide higher data rates to meet the demand for extremely fast user experience rates and large system capacity in hotspot areas, such as those deployed in large stadiums, airports, and public squares. This type of scenario involves little or no obstruction, high user density, and large traffic demand. MmW base stations need to be deployed in scenarios with rich reflection paths, such as commercial streets and office buildings.
