With the rapid development of wireless communication technologies, millimeter-wave (mmWave) communication has become a crucial research direction for next-generation wireless networks due to its abundant spectrum resources and high-bandwidth transmission capabilities. This paper focuses on the applications and challenges of mmWave communication in wireless networks, aiming to explore its key technologies and potential issues in practical deployment. By integrating theoretical analysis with simulation validation, this study delves into the application scenarios of mmWave communication in 5G and future 6G networks, including high-speed mobile communication, Internet of Things connectivity, and intelligent transportation systems, while systematically investigating aspects such as propagation characteristics, channel modeling, and beamforming techniques. The findings indicate that mmWave communication can significantly enhance network capacity and data transmission rates; however, it also encounters challenges such as severe signal attenuation, weak penetration capability, and complex hardware implementation. To address these challenges, this paper proposes an mmWave signal enhancement scheme based on intelligent reflecting surfaces, effectively mitigating signal propagation loss, and experimentally verifies its feasibility and superiority. Additionally, an adaptive beam management algorithm is designed, substantially improving beam alignment accuracy and communication stability. In summary, this study not only reveals the immense potential of mmWave communication in wireless networks but also provides new insights and technical support for resolving critical issues in its practical applications, laying a theoretical foundation for the optimized design of future mmWave communication systems.
