In this paper, we analyze a 28 GHz suburban channel using a hybrid ray-tracing simulation. Hybrid ray-tracing technique is a combination of image method and shooting-and-bouncing rays (SBR) method. The SBR method finds a rough propagation path and the image method predicts the exact propagation path. The hybrid ray-tracing simulation is compared with a measurement campaign conducted in Wolpyeong-dong, Daejeon, Korea, and its performance is verified. The transmitter is placed on a 29m building; the heights of the other buildings are between 10m and 12m. Based on a reasonable agreement between the results of ray-tracing and the measurement results, five streets of Wolpyeong-dong were analyzed using ray-tracing simulation. The path loss, power delay profile, root mean square delay spread, angle of arrival and angular spread were obtained.
