Apparatus and method for estimating cell coverage using interference model
First Claim
1. An apparatus for estimating a cell coverage, which estimates a cell coverage according to the output of a base station and a propagation loss, the apparatus comprising:
- a terrain data processor for dividing an area for calculation of the coverage into pixels of a predetermined size;
a traffic calculator for estimating a traffic volume by the respective pixels;
a forward coverage estimator for calculating path loss information according to the pixel-based traffic volume and a predetermined traffic carrying capacity of the base station and determining a forward link capacity and a forward coverage; and
a backward coverage estimator for calculating a same-cell interference and an adjacent-cell interference using the path loss information between the base stations and determining a backward link capacity and a backward coverage.

Abstract
An apparatus and method for estimating a cell coverage includes: a terrain data processor for dividing an area for calculation of the coverage into pixels of a size; a traffic calculator for estimating a traffic volume by the pixels; a forward coverage estimator for calculating path loss information according to the pixel-based traffic volume and a traffic carrying capacity of the base station and determining a forward link capacity and a forward coverage; and a backward coverage estimator for calculating a same-cell interference and an adjacent-cell interference using the path loss information between the base stations and determining a backward link capacity and a backward coverage, thus determining a cell coverage approximating the actual coverage by including a same-cell interference and an adjacent-cell interference.
