Abstract :
Wideband channel characteristics associated with UHF wave propagation within a shopping mall in urban areas are presented in this paper. Impulse responses, decay rate of multipath components as well as the root-mean-square (RMS) delay spread obtained from wideband sounding are studied for both the same level propagation and the inter-level propagation. Due to the enclosed structure of the shopping mall, multipath components are mainly resulted from multiple reflections within the building and therefore they decay linearly for both test scenarios. Moreover, the delay spread value obtained from the measurements is within 100 ns, therefore, the usable bandwidth is sufficient for video communication.
