Abstract

The invention provides a wireless intelligent propagation method based on a Cost231-Hata model. The model is based on application of a 5G network and assistance of wireless LET network data, and provides a wireless propagation model which is established in different environments and under the influence of various external factors and is high in stability. According to the model, engineering parameters, map parameters and self-searched features in LET data are analyzed; the average signal received power (RSRP) of the model is predicted; detailed division of loss of a transmission path is considered; a more comprehensive transmission path loss is adopted and is composed of a free space loss Ls and a diffraction and scattering loss Lms of a roof to a street, a back propagation neural networkis constructed to predict RSRP at different geographic positions, and the coverage intensity of wireless signals in a new environment can be accurately predicted through the model, so that the networkconstruction cost is reduced, and meanwhile the network construction efficiency is improved.

Description

technical field [0001] The invention relates to a wireless intelligent propagation method based on the Cost231-Hata model, which is convenient for using the model to accurately predict the coverage strength of wireless signals in a new environment. Background technique [0002] Nowadays, artificial intelligence has been pushed into a strong position, and both industry insiders and other companies are chasing it crazily. At the same time, the topic of 5G is no longer a theory that exists on paper, but a silent one. Voice appears in the field of artificial intelligence, and has achieved outstanding progress, and its applications around the world are constantly expanding. [0003] In the field of 5G applications, the three major communication operators are competing to deploy 5G networks. In this application, the most critical aspect is the rational selection of base station sites within the coverage area. Secondly, the deployment of base stations to meet the needs of users co...
