This research aims to develop accurate path loss models for outdoor millimeter-wave propagation across multiple frequency bands.
Analyzed outdoor mmWave propagation at 28, 38, 66, 71, and 90 GHz using ray tracing simulations.
Examined path loss models in both line of sight (LOS) and non-line of sight (NLOS) conditions.
Focused on urban locations in Istanbul, Turkey.
Path loss exponents ranged from 2.35 to 2.86 in LOS and 2.54 to 3.3 in NLOS, with standard deviation of 3–11.79 dB.
The Floating Intercept (FI) model performed best in LOS conditions.
Angular analysis revealed significant variation in angles of arrival, indicating stronger multipath dispersion at lower frequencies.
