Abstract

The invention provides a method for realizing wireless communication network frequency planning based on a GIS system, comprising: step 1: using geographic data, station data, and available frequencies provided by the GIS module as calculation parameters to obtain preliminary results of model prediction; step 2: Perform frequency planning according to the preliminary results of the model prediction, and obtain the frequency planning results; Step 3: Conduct electromagnetic coverage analysis according to the preliminary results of the model prediction, and output the coverage analysis image; Step 4: Perform link connectivity analysis according to the preliminary results of the model prediction, and output the link Analyze images. The present invention is based on the GIS system, introduces geographical information into the planning process, applies the ITU-R P.1546 propagation model to predict the communication effect of each site at different frequencies under the actual geographical environment, and finally selects the frequency that meets the communication requirements as the planning result.

Description

technical field [0001] The invention relates to radio wave propagation prediction technology, in particular to a method for realizing frequency planning of a wireless communication network based on a GIS system, in particular to ultrashort wave propagation prediction technology. Background technique [0002] The working frequency band of the ultrashort wave radio station is 30-87.975MHz. The electromagnetic wave diffraction ability in this frequency band is weak, and it is greatly affected by the topography, which is a typical line-of-sight transmission. [0003] However, in the traditional frequency planning scheme, the planning process still mainly relies on manual allocation, and does not consider the influence of topography. The software only provides the user with a man-machine interface, and the user manually plans the frequency information of the communication network according to his own experience. During the planning process, users need to do a lot of manual opera...
