We describe a scalable method for predicting radio channel path-loss in cluttered environments. The method is designed for constructing path-loss look-up tables that can be integrated with a mobile wireless network simulation. The proposed simulation technique is a much simplified version of the transmission line matrix method; the simplifications allow for an event based simulation using a coarse spatial grid. This, in turn, makes it possible to roughly approximate site specific radio channel path-loss on a scale that is suitable for simulating wireless LANs. Two validation studies demonstrate the utility of the proposed approach.
