This paper presents the large-scale parameters of narrowband multipath channel propagation of corridor environments for the fifth generation (5G) communications system. The measurements were conducted on narrow, wide and open corridor structure in Universiti Teknologi Malaysia (UTM) Kuala Lumpur campus, Malaysia. Measurements campaign are conducted at 6.5 GHz and 10.2 GHz , and path loss exponents (PLEs) and shadow fading are extracted using linear-least-square regression fitting from measured received-signal-strength (RSS) . Furthermore, the results measurements campaign is modeled using well-known closein reference distance (CI) and floating-intercept (FI) models. The result found in this work discovered the breakpoint distances (bps) of radio propagation are seen varies differently at those corridors for diverse frequencies.
