Performance and Measurement Analysis of a Commercial 5G Millimeter-Wave Network

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.

5G Campus Networks: A First Measurement Study

“…Generally, measurements conducted in testbeds built from prototype equipment are a critical step in the research and development of complex engineering systems, such as 5G communication systems [23]- [27]. To date, 5G testbed measurements have primarily focused on characteristics of the physical layer of the 5G communication system, such as 5G electromagnetic field exposure [28], 5G radio coverage evaluation [29], and similar 5G physical layer aspects [30]- [37]. Another set of testbed studies have focused on 5G aspects related to multi-access edge computing (MEC), i.e., the paradigm of integrating computing capabilities into the 5G communication network infrastructure and operation, e.g., for in-network computation processing [38]- [40] and in-network re-coding of communication data packets [41]- [43].…”

Adaptive simulation of digital signal transmission

“…However, more advanced algorithms also introduce additional challenges. When compared to traditional medium and low-frequency base stations, the propagation characteristics of millimeter waves have engendered issues of link instability and interference in expansive networks [7]. For instance, the transition from 8QAM to 16QAM, 64QAM, or even higher coding introduces enhanced transmission rates but concurrently jeopardizes signal stability.…”

Passive intelligent reflecting surfaces based on reflectarray panels to enhance 5G millimeter-wave coverage

“…A close consideration has been given to the signal propagation conditions in the mm-wave bands, which are more adverse than those in the sub-6 GHz bands, due to the higher path loss and larger sensitivity to blockage [3, 4]. In outdoor scenarios, the presence of high buildings or other structures in the surroundings of a 5G base station (BS) may result in blind zones (with poor coverage) [5]. In the case of indoor scenarios, walls and glass panels can easily block mm-wave signals, producing link instability and coverage problems if the mobile users are not in direct line of sight from the BS [6].…”
