Abstract :
An efficient approach to revealing the propagation characteristics for broadband mobile services in the 5-GHz microwave band is to utilize the existing 2-GHz band propagation data accumulated by many researchers. This paper presents the height variation characteristics at 5.2-GHz compared with that at 2.2-GHz in a residential area based on experiments and theoretical analysis. Propagation measurements were carried out using the dual band antenna at 5.2-GHz and 2.2-GHz, and the measured results were compared. Furthermore, this paper compares the measured results with the calculated results using a two-dimensional (2D) ray-tracing approach based on geometric optics (GO) and the uniform geometrical theory of diffraction (UTD)
