Abstract:
A method for assigning an area of transmission to a plurality of sector base stations in order to provide a total number of said sector base stations required in an actual working environment, said method comprising the steps of:(a) calculating a ratio of the coverage area of a sector base station to an omni base station, wherein the antenna gain of said omni base station and said sector base station is identical and wherein the coverage area of said sector base station is calculated by determining a radius of a horizontal beamwidth for each antenna angle to yield a maximum allowable path loss; calculating a circle area for each antenna angle using said determined radius and dividing said each calculated circle by 360, and summing up said each calculated circle area for said each antenna angle; (b) calculating an area of transmission for said omni base station having handover area according to the following equation: Somni=3Ã—32Ã—R2,wherein R represents a cell radius;(c) multiplying said calculated ratio in step (a) and said area in step (b) to determine said area of transmission for said sector base station having handover area; and, (d) assigning said area determined in step (c) to each of said plurality of sector base stations.
