This thesis examines methods to enhance the realism of signal strength simulations in a Radio Access Network (RAN) test environment by identifying and analyzing factors that influence signal strength in actual RAN settings. The study addresses different attenuation impacts using three technical reports: 3GPP TR 38.901 for path loss in various area scenarios, ITU-R P.838 for rain attenuation, and ITU-R P.840 for cloud and fog attenuation effects. This thesis also considers inter-cell interference as a proof of concept to understand its impact on signal quality. Key findings indicate that path loss substantially affects signal strength, significantly influenced by frequency, distance between transmitter and receiver, and the environmental context (e.g., rural or urban). Although rain and cloud attenuation also affect signal strength, their impact is minor but increases with higher frequencies. This thesis enriches our understanding of more accurately simulating signal strength in RAN environments by focusing on path loss, rain, cloud attenuation, and inter-cell interference. This work lays a foundation for subsequent studies to expand upon, particularly in integrating diverse attenuation factors, thereby driving forward the precision and reliability of future RAN simulations.
