Abstract-In this paper, we focus on multipath channel characteristics of low-height antenna links for mobile to mobile communications in urban street grid environments. We present a wideband MIMO channel sounder and antennas used to measure multipath channel characteristics at 3.7GHz frequency band and the result of calibration test to evaluate a system performance before field measurement. We carried out a channel measurement campaign in urban street grid environments in Seoul, Korea. The results of multipath characteristics from collected data in field measurement are compared with the conventional ITU-R channel model parameters in terms of r.m.s delay spread, and angular spread of arrival and departure.

“…The deterministic models in this report use ray-tracing methods (for 3-D models) and vertical plane diffraction methods (for 2-D models) to predict RF propagation. Ray-tracing methods are considered relatively accurate and computationally fast compared to other propagation methods (Yun and Iskander 2015;Lu, et al 2010). Specifically, these models use Remcom Wireless InSight (WI) software:…”

Newly developed radio-frequency propagation models estimate signal strength, signal coverage, and bit error rates to support mission planning for robotic platforms operating in urban areas. This study involved highfidelity modeling on a graphics processing unit workstation and included full three-dimensional analysis of reflection, transmission, and diffraction propagation effects within urban landscapes. Real-time propagation modeling is made possible using an application programming interface (API) with simpler, faster models whose output can, in principle, be used for mission planning or platform performance assessment within a virtual scene. This report presents the results of two test cases-within a virtual rendering of the U.S. Army Cold Region Research and Engineering Laboratory campus and within a fabricated dense urban scene-to demonstrate the ability to generate high-fidelity radio-frequency propagation models from building and terrain data derived from (1) LiDAR (Light Detection and Ranging) and digital elevation models and (2) Virtual Autonomous Navigation Environment (VANE) scenes. This report outlines steps necessary to produce lower fidelity, higher speed models using the API and discusses how the API could interface with existing virtual environments and mission-planning tools.

In this paper, we investigate multipath azimuthal distribution characteristics between terminals considering for mobile-to-mobile communication scenarios in urban street canyon environments. We carried out channel measurement campaigns on 3.7GHz frequency band at three sites in Seoul, Korea. The root mean square (r.m.s.) angular spread characteristics are analyzed with results of their distribution and cumulative density function (CDF) in line of sight (LoS) and non-LoS (NLoS) case respectively.
