The purpose of the study is to characterize the channel at 28 GHz for 5G communications system in line-of-sight (𝐿𝑂𝑆) corridors environment. Measurement campaigns were conducted to measure the wireless signal of received signal strength at three different construction of straight corridors, narrow, wide and open corridors. The large-scale path loss models are developed using the closed-in reference distance (𝐶𝐼) and floating – intercept (𝐹𝐼) modelling approaches. Besides contributing path loss (𝑃𝐿) models at 28 GHz for different corridors dimension, the result found in this work discovered the breakpoint distance (𝑑𝑏𝑝) of radio propagation is seen varies differently at those corridors. PLE in CI model, open corridor significantly exaggerates of 1.92 compared to the narrow and wide corridor of 1.60 and 1.83 PLEs respectively. The lower than freespace (PLE is 2) in the corridors, attributes to the waveguide phenomenon within the corridors.en-US5GRadio propagationPath loss modelsCorridorstext::journal::journal article8696461
