Mobile phone base station signal coverage range simulation method based on Thiessen polygon

Abstract

The invention relates to the technical field of signal simulation, and particularly relates to a mobile phone base station signal coverage range simulation method based on a Thiessen polygon. The method comprises steps: multiple scattered points are generated on map data, whether the scattered points are intersected with habitable buildings in the map data is judged, and a habitable area of each scattered point is recorded; a home base station of each scattered point is found out, and the habitable area corresponding to each home base station is counted; the habitable area is divided by a recognized resident population, and the per-capita living space is obtained; the weight of the base station is acquired according to the per-capita living space; in combination with the weight of each base station, the new home base station of each scattered point is acquired again; the per-capita living space of the new home base station is judged, and the vector data information is obtained; and the vector data information is converted according to a sequence to obtain the base station coverage range after correction. The operation is simple, the obtained base station coverage range data are accurate, and the popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of signal simulation, in particular to a method for simulating the signal coverage range of a mobile phone base station based on Thiessen polygons. Background technique [0002] With the development of science and technology, today's society has entered the era of big data; in today's society, mobile phone data is often used to accurately simulate people's residences, and the data obtained is conducive to researchers' in-depth understanding of various social situations; and based on In the accurate simulation method of residence based on mobile phone data, it is a commonly used method at present to use the signal coverage of mobile phone base stations to simulate the residential area of ​​the number of residents identified by the base station. The determination of the signal coverage of mobile phone base stations can be calculated by professional software such as KATHREIN of Catherine Company, ATOLL AIRCOM o...

Problems solved by technology

These two methods have their own advantages and disadvantages: the coverage of each base station can be calculated more accurately through professional calculation software, but the operation of professional software requires more parameters to be input into the software, such as antenna height and signal transmission power. , azimuth, downtilt, etc., have more background knowledge requirements for the communication industry, so it generally needs to be done by professionals

Its advantage is that the operation is relatively simple, and the coverage of the cell phone base station signal can be obtained only by taking the location of the cell phone base station as an input parameter; but its disadvantage is that because the Thiessen polygon only considers the geometric properties of the base station location, it does not consider Base station coverage is affected by factors in actual use, such as population density, so the simulation accuracy is not as high as the simulation results of professional software
