A Comprehensive Study on Statistical Channel Modeling for Outdoor to Indoor (O2I) Penetration Concern of 5G mmWave Access Networks

As wireless communication continues to evolve, the exploration of millimeter-wave (mmWave) frequencies has emerged as a promising avenue for achieving unprecedented data rates and ultra-low latency. This paper delivers a statistical comprehensive analysis of outdoor-to-indoor (O2I) penetration loss in mmWave communication scenarios. The study illustrates directional power delay profiles and uncovers intricate O2I loss patterns across a spectrum of frequencies and diverse scenarios. In the pursuit of a robust understanding, we conduct simulations to discern the interactions between antenna orientation, frequency, and signal propagation. More significantly, our analysis of O2I penetration loss at different azimuth and elevation angles sheds light on the critical interplay between building materials, obstructions, and signal attenuation. The implications of this study resonate with real-world applications, such as network deployment and coverage optimization.
