For predictions of vehicle to vehicle communications, convoy communications, and Improvised Electronic Device (IED) detection/defense operations, Remcom's Wireless InSite Real Time (RT) module provides a very rapid propagation prediction capability in urban environments. Previous models are either empirical and inaccurate but fast, or deterministic and high-fidelity but slow. The RT Module takes the best of both; it is deterministic and provides higher-fidelity results than empirical models and is much faster than full physics-based models, returning a point-to-point result in milliseconds. It is free of the spatial limits of empirical models. This paper will show how the Wireless InSite Real Time Module can be used to provide accurate communication and jamming predictions for mission planning tools in near real time. The RT module allows user-defined mobile objects to be placed into the urban scene and rapidly repositioned without expensive reloading of geometry. The C++ API permits developers to quickly integrate the RT capability into their Tactical Decision Aids (TDA's) and other graphical visualization tools.
