METHOD OF ESTIMATING CELL COVERAGE IN THE WIRELESS-NETWORK DESIGN SYSTEM

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a cell coverage estimation method in a wireless network design system.;2. The technical problem to be solved by the invention;According to the present invention, in order to improve the calculation speed of the radio wave analysis function implemented in the wireless network design system, the cell coverage may be roughly estimated in advance using LOS (Line Of Sight), or may be applied to all bins corresponding to each radial. Cell coverage estimation method that estimates the cell coverage in advance by calculating the received signal power only for the minimum bins needed for cell coverage calculation using arbitrary search techniques such as binary search scheme, etc. The purpose is to provide;3. Summary of Solution to Invention;The present invention includes a first step of reading information about a terrain and searching for a line of sight (LOS) path for all radials; A second step of concatenating all discovered LOS points to obtain a service area; And a third step of outputting the obtained service area, so that the service range can be estimated within a shorter time in setting the location of the base station.;4. Important uses of the invention;The present invention is used in a wireless network design system.
