High-rate access in outdoor urban areas using extremely high frequency (EHF) bands, known as millimeterwave (mmWave) spectrum, requires a dense deployment of wireless small cells in order to provide continuous coverage to serve bandwidth-hungry users. At the same time, to be able to collect a sufficient amount of data for constructing detailed EHF propagation models, a considerable number of various landscape maps across different scenarios has to be considered. This letter develops a shoot-and-bounce ray (SBR) based methodology capable of characterizing the mmWave propagation in urban outdoor conditions. In particular, our methodology aims to capture a large number of small cells within accurate, real city maps and then to utilize an algorithm of automatic transmitter placement. Hence, our contribution is to provide with a suitable tool that is able to handle massive ray-based simulations within a reasonable time frame. In particular, we demonstrate and verify that a shift from simulating 3D to evaluating 2D environments significantly reduces computation time while only slightly decreasing the simulation accuracy.
