An Overview of Wireless Communication Propagation Models
Year: 2025
Type: article
Abstract: Wireless communication has become an essential pillar of modern technological advancements, supporting diverse applications such as telecommunications, smart cities, and autonomous systems. At the heart of these systems lies radio wave propagation, which governs how signals travel between transmitters and receivers. The study traces the historical development of propagation modeling, from foundational theories established by Maxwell and Hertz to modern computational approaches that address the complexities of urban and indoor environments. Key propagation phenomena, including reflection, diffraction, and scattering, are examined, along with classification criteria such as large-scale, medium-scale, and small-scale fading. The manuscript further investigates the utilization of models such as the Free Space Model, Okumura-Hata Model, and Ray Tracing Model in enhancing base station configurations, satellite communication, and other essential systems. In addressing future challenges, the paper identifies terahertz communication as a focal point, emphasizing the impact of water molecule interactions on signal attenuation. Emerging trends, including millimeter-wave frequencies, terahertz signal attenuation, and dynamic conditions, are also discussed.
