Abstract
A method and apparatus for modeling radio propagation is provided. In the method, when a wall having a thickness is modeled as a line having no thickness, an error in a shade area is minimized by considering the thickness of a wall while maintaining simplicity in a ray-tracing method.
Claims8
A radio propagation modeling method using a ray-tracing method, the radio propagation modeling method comprising:
- determining the position of a transmitter with respect to an obstacle in a radio propagation modeling area;
- predicting a shade area, generated by a radio wave output from the transmitter, based on a horizontal linear length of the obstacle;
- and
- correcting the shade area considering the thickness of the obstacle.
