Modelado de las pérdidas de propagación en un escenario de oficinas en bandas de milimétricas

[EN] In this conference contribution, we present millimeter-wave (mmWave) propagation measurements for an office environment from 25 to 40 GHz and investigate the path loss using the most common empirical models proposed in WINNER-II and adopted by the 3GPP: the single-frequency floating-intercept (FI) model, the single-frequency close-in (CI) free space reference distance model, the multi-frequency alphabeta-gamma (ABG) model and the close-in free space reference distance with frequency path loss exponent (CIF). Both line-ofsight (LOS) and obstructed-LOS (OLOS) propagation conditions have been considered. The mean value of the model parameters, and their 95 % confidence intervals, have been derived using regression and optimization techniques.
