There are general models and deterministic models of propagation characteristics in indoor and outdoor environments in wireless communication applications. The deterministic Site-specific models are based on ray tracing. The deterministic prediction method provides path loss and field strength by reflection of imaging methods and uniform theory of diffraction (UTD). We present approaches to the extended method for deterministic ray-based propagation prediction method. Research is underway on the application of deterministic and stochastic hybrid models as an extension of radio propagation model. We are also considering the experimental results of a ray tracing algorithm that adds a diffuse scattering method for indoor propagation environment modeling. The real material properties will be measured for four frequency bands and apply it to the ray-based analysis method which considers direct, reflection, and diffraction path. This deterministic methods for large scale parameters combine stochastic method for small scale parameters of propagation model.
