Abstract

With the development of 5G communication technology, millimeter-wave (mmWave) communication has become crucial for enhancing 5G network performance due to its characteristics of high frequency bands and large bandwidth. This study aims to explore in depth the applications and challenges of mmWave communication technology in 5G, providing theoretical foundations and technical support for optimizing 5G networks. By analyzing the principles of mmWave communication technology and integrating them with the features of 5G network architecture, this research employs a combination of theoretical derivation and simulation experiments to investigate the potential applications of mmWave communication technology in high-speed data transmission and low-latency communication. The findings indicate that mmWave communication technology can significantly increase the data transmission rate and spectral efficiency of 5G networks, demonstrating excellent performance in scenarios such as hotspot area coverage and high-density user access. However, mmWave communication also encounters issues like significant propagation loss and weak penetration capability, which limit its broad application. To address these challenges, this study proposes improving the propagation characteristics of mmWave signals through techniques such as intelligent reflecting surfaces and large-scale antenna arrays, which represents one of the innovations of this research. Additionally, a channel model suitable for mmWave communication has been constructed, offering a reference fr amework for subsequent studies, which is also one of the main contributions.
