Abstract

This study explores how different materials affect signal transmission in 5G networks, specifically in the 28 GHz spectrum known as Frequency Range 2 (FR2). Using an anechoic chamber, the research measures Reference Signal Received Power (RSRP), Signal to Noise Ratio (SNR), Throughput, and Block Error Ratio (BLER) with and without obstacles like wood, glass, and metal at various angles. The goal is to gain a thorough understanding of how materials impact signal strength in 5G FR2 networks, in order to improve propagation models. The study presents results on physical and network metrics based on the angle of the User Equipment (UE), showing that the 5G FR2 network is resilient against dielectric, wood, and glass obstacles, but sensitive to conductive materials. This research helps in designing networks that can handle high throughput demands, identifies challenges in signal propagation, assesses penetration loss in building materials, and contributes to refining path loss models for better network performance.
