Path Loss Measurements in Indoor Corridor at 18 GHz: LoS and NLoS Scenarios at Multiple Receiver Heights

This dataset contains large-scale path loss measurements collected in an indoor corridor environment at 18 GHz. Measurements were conducted under both line-of-sight (LoS) and non-line-of-sight (NLoS) conditions, where NLoS is defined by a 90° corner junction between two corridor segments. The dataset comprises six CSV files organized by propagation condition and receiver height (0.61 m, 1.30 m, and 1.91 m above floor level). Each file contains two columns: distance_m (horizontal Manhattan distance in meters) and path_loss_db (measured path loss in dB). Data were collected using narrowband equipment and directional horn antennas.
