The embodiment of the invention provides a field intensity prediction method and device and computer equipment. The method comprises the following steps: acquiring coordinate information of a target measurement point in a target area, inputting the coordinate information into a corrected ray tracking field intensity prediction model, and obtaining the receiving field intensity of the target measurement point output by the ray tracking field intensity prediction model. Thus, in the model correction process, the influence of propagation parameters and scene parameters is considered, so that thereceiving field intensity of the target measurement point output by the ray tracking field intensity prediction model based on multipath information correction can be accurately obtained, the physicalsignificance is clearer, the application deployment range is more appropriate, and the robustness is higher.
Description
technical field [0001] The present application relates to the field of mobile communication technology, in particular to a field strength prediction method, device and computer equipment. Background technique [0002] The coverage prediction and interference prediction of radio wave propagation are not only the basis of wireless network base station deployment planning, but also the premise of accurately optimizing the problems existing in the existing network. At the same time, ray tracing is a technology widely used in mobile communication and personal communication environment to predict radio wave propagation characteristics, which can be used to identify all possible ray paths between transceivers in multipath signals. [0003] However, the existing field strength prediction model based on ray-tracing technology relies on scene information, which has not been accurately measured during the deployment and planning of wireless network base stations, which will lead to the...
