Cell Coverage Estimation in Wireless Network Design System

摘要

1. Technical field to which the invention described in the claims belongs;The present invention relates to a cell coverage estimation method in a wireless network design system.;2. Technical Challenges to be Solved by the Invention;In order to improve the calculation speed of a radio wave analysis function implemented in a radio network design system, the present invention estimates cell coverage beforehand by using LOS (Line Of Sight), or estimates cell coverage in all bins corresponding to each radial A cell coverage estimation method that roughly estimates the cell coverage by calculating the received signal power only for the minimum number of bins necessary for the cell coverage calculation using an arbitrary search technique such as a half search technique instead of calculating the received signal power The purpose is to provide.;3. The point of the solution of the invention;The present invention includes a first step of searching for a line of sight (LOS) path for all radials by reading information about the terrain; A second step of finding a service area by connecting all the LOS points searched; And a third step of outputting the obtained service area, so that the service range can be estimated in a shorter time when the base station is located.;4. Important Uses of the Invention;The present invention is used in a wireless network design system.
