Abstract

The invention discloses a transmission environment dividing method based on existing network test data, which comprises the steps of: acquiring existing network engineering parameters and existing network test data; carrying out correction test on the traditional transmission model by using a planning simulation tool on the basis of the existing network engineering parameters and the existing network test data, obtaining a transmission model of each cell / site / region; and based on the transmission model of each cell / site / region, classifying the transmission environment of the planning region. The invention also discloses a transmission environment dividing device based on the existing network test data, which comprises an existing network data acquiring module, a transmission model correction module and a transmission environment classifying module. The method and the device can realize that the transmission environment of the planning region is divided by testing and correcting the transmission model.

Description

technical field [0001] The present invention relates to network planning and design in the field of wireless communication, in particular to a propagation environment division method and device based on live network test data, which can be applied to the planning and design of new networks or expanded networks. Background technique [0002] In the traditional mode, in the planning and design of wireless networks, it is necessary to select some typical sites to organize propagation model correction tests, and then apply the propagation models obtained by these typical site tests and corrections to relevant sites for simulation, and evaluate the planning and design scheme based on the simulation results. reasonableness, to determine whether adjustments are required. [0003] The final solution of planning and design is largely affected by the simulation effect; and the simulation effect is also subject to the propagation model selected by each cell. It can be seen that the ty...
