摘要： A method (10 or 500) and system (200) for simulating and improving accuracy of empirical propagation models for radio frequency coverage can include a display (210) and a processor (202) coupled to the display. The processor can be operable to input (502 and 504) low-resolution data and high-resolution data, select (506) an area of interest being simulated for empirical propagation models, and classify (508) receivers as belonging to a predetermined type of object. If a receiver in the area of interest is a low resolution object, then normal losses can be applied (510). If a receiver in the area of interest is a high resolution object, then losses specific to the high resolution object can be applied (512). If a receiver is classified as being inside a building, then the processor can further compute (516) a median power for a location of the receiver and add in-building penetration losses.

摘要： A method (600) and simulation tool (200) having enhanced accuracy and speed for simulation using ray launching in a mixed environment (20) by using adaptive ray expansion mechanisms can include a memory (204) coupled to a processor (202). The processor can select (602) a target area within the mixed environment and modify (604) 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 (230) externally attached to a device performing functions of the simulation tool.

摘要： A method (20 or 500) and system (200) for method for computing wireless signal diffraction in a three-dimensional space can include the steps of selecting at least a source point, finding (19) sinkpoints that fail to have a line-of-sight path to the source point and storing the sinkpoints found, placing (21) diffraction points on all edges of a three-dimensional geometry, and building (24) a visibility matrix based on weighted paths for all source points and all sink points. The method can further include applying (25) a path finding algorithm on the visibility matrix for each sink point to all source points and storing store optimal paths for each source point to all sink points if they exist. The method can further include determining (23) if a last source point is selected before building the visibility matrix.

摘要： A system (100) and method (400) for improving Radio Frequency (RF) Antenna Simulation is provided. The method can include determining (402) a proximity of an antenna (250) to a scattering structure (210), determining (410) a switching distance to the scattering structure that establishes when to switch the antenna on (416) and off (418) 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.

The method can define (14) the low resolution database and identify (18) the higher resolution setting. The method can also save (26) a composite resolution database. The method can use an aerial image and its pixilation to create a higher resolution image by interpolation to form a higher resolution image.
