An Empirical Approach to Omnidirectional Path Loss and Line-of-sight Probability Models at 18 GHz for 5G Networks

Performance study of path loss models at 14, 18, and 22 GHz in an indoor corridor environment for wireless communications

“…6 represents the floor plan of the indoor corridor environment adopted. More information about these measurement campaigns can be found in [1], [19], [20].…”

“…Furthermore, the penetration loss through solid materials significantly affects the mmWave frequency spectrum [3], [17]. Hence, accurate understanding and characterization of behaviors of the mmWave frequency bands in numerous indoor and outdoor environments and scenarios are fundamental for performance analysis and reliable deployment of the 5 cellular systems [13], [15], [18], [19].…”

“…Accurate path loss models are essential for indoor corridor environments in the candidate mmWave regime for applications in future generation communication systems [20]. The 5 networks will rely on the LOS probability in terms of the coverage capability in indoor corridor environments [19].…”

“…Omnidirectional path loss models and LOS probability based on real measured data were presented in [19] for an indoor corridor environment at 18 frequency band where the transmitting and receiving antennas had no obstacle between them and pointed toward each other with alignment on boresight (i.e., LOS scenario). The study compared two empirical path loss models, i.e., the CI and DS models.…”

A Brief Review of Path Loss Models for mmWave Channels

“…Measurements were performed using a directional horn antenna, then based on the comparison of CI and FI path loss models they suggest that CI model is more suitable in the outdoor semicorridor environment then FI model. Another measurement method was used in [30] within the band of 18 GHz. By using a horn antenna radiation, the omnidirectional path loss synthesis has been confirmed, then in the measured data, the dual slope (DS) and CI path loss models were structured.…”
