Efficient site-specific mobile-mobile urban propagation modeling is critical to a variety of applications, including spectrum management, spectrum and communications systems planning, and dynamic spectrum access policy development. Currently popular RF urban propagation models do not specifically consider the impact of actual urban environments and do not address mobile-to-mobile propagation scenarios. To address this, we implemented Urban Propagation Model (UPM) to predict path loss taking into account actual building geometry for each path with minimal time and computational complexity. In this paper we report the result of UPM validation that compared measurement taken in a representative urban environment with UPM path loss predictions. The results show that for this set of measurement, the UPM calculations are within a 5 dB standard deviation and 8 dB root mean square error.
