Abstract

The embodiment of the invention provides an electromagnetic wave propagation path ray-tracing method, device and system. The method comprises the steps of determining an effective plane of a signal sending point according to a preset effective plane selection radius; for each ray sent by the signal sending point, detecting an intersection point between the ray and the effective plane along the direction of the ray; and determining a next path direction of the ray, until the ray arrives at a receiving area of a receiving point or the accumulated reflection equivalent of the path of the ray passing the effective intersection point is more than the preset maximum reflection equivalent, if the intersection point exists between the ray and the effective plane and the accumulated reflection equivalent of the path of the ray passing the effective intersection point is not more than the preset maximum reflection equivalent. Through application of the embodiment of the method, the device and the system, the complexity of the calculation process in the path ray-tracing process is reduced, the high-efficiency and accurate electromagnetic wave propagation path simulation is realized, and the electromagnetic wave propagation characteristic in an observed wireless network can be obtained.
