A method () and simulation tool () having enhanced accuracy and speed for simulation using ray launching in a mixed environment () by using adaptive ray expansion mechanisms can include a memory () coupled to a processor (). The processor can select () a target area within the mixed environment and modify () the propagation properties of the adaptive ray expansion mechanisms according to characteristics classified for the target area. The processor can further classify characteristics for the target area by transmitting and reflecting rays for indoor building regions and for outdoor building regions. The number of bounces or a power level threshold assigned to a transmitted ray is a function of the environment where it propagates. The simulation tool can determine the target area or a region of interest by using a global positioning service device () externally attached to a device performing functions of the simulation tool.

Method and apparatus for enhancing the accuracy and speed of a ray launching simulation tool

A system () and method () for improving Radio Frequency (RF) Antenna Simulation is provided. The method can include determining () a proximity of an antenna () to a scattering structure (), determining () a switching distance to the scattering structure that establishes when to switch the antenna on () and off () from a composite antenna pattern to a free space antenna pattern, and predicting RF coverage of the antenna responsive to the switching. The switching distance can be a function of a material type and a surface geometry of the scattering structure and a wavelength of the antenna. The method can also include evaluating a sensory mismatch in the antenna, and using a composite antenna pattern corresponding to the sensory mismatch.
