Title: Method of creating tilt map for wireless network planning system
Inventor: CHO GYEONG SEON
IPC: H04B7/26
Filed: 2002-04-24
Abstract: PURPOSE: A method for generating a tilt map in a cell planning system is provided to use a minimal tilt in a region after a diffraction point according to diffraction properties of propagation, and to generate the tilt map during diffraction, thereby exactly analyzing the propagation. CONSTITUTION: A cell planning system sets the number of maximum cells, stores a minimal tilt, and initializes the minimal tilt with a positive unlimited value(601). The system calculates tilts from the first cell(602), and compares the calculated value with the minimal tilt(603). If the calculated value is smaller than the minimal value, the system inserts a newly calculated tilt value(604). If the calculated value is not smaller, the system sets the minimal value to a tile value from a current position(604). The system repeats the process until a final cell(606).
