Azimuth, Elevation, and Delay of Signals at Mobile Station Site

Abstract

We analyzed channel sounder measurements at 890MHz in a dense urban environment where the receiver was located at the mobile station site. The joint information of delay, azimuth and elevation allows a thorough study of the main propagation mechanisms. There is a clear indication that street canyons dominate propagation in a dense urban environment, but scatterers all around the mobile station contribute to the power delay profile. For the macrocells investigated, there is a considerable over-the-roof propagation. Our results corroborate the hypothesis of multiple reflections/diffractions in urban macro cells.
