Title:
METHOD AND DEVICE FOR ESTIMATING AP POSITION USING A MAP OF A WIRELESS LAN RADIO ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2012/005465
Kind Code:
A2
Abstract:
An embodiment of the present invention relates to a method and device for estimating AP position using a map of a wireless LAN radio environment. The device for estimating AP position using a weighted average of the signal intensity includes: a filtering unit generating a filtering radio map, which selects only data having the same MAC address in the map of a connected wireless LAN radio environment; a grid cell dividing unit generating a grid radio map which divides the filtering radio map into arbitrary grid cells; a unit for mapping a coordinate representative value which calculates the center value from each grid cell constituting the grid radio map and mapping each center value into each grid cell with a coordinate representative value; a unit for mapping a representative value for the signal intensity which calculates the same on the basis of the data in each grid cell and maps each representative value of the signal intensity into each grid cell with the same; a unit for selecting the weighting value which selects the same corresponding to a range to which the intensity of the reception signal of the representative value of the signal intensity also corresponds; and a unit for estimating position which estimates the position information of AP having the same MAC address on the basis of at least one of the following: coordinate representative value, the representative value of the signal intensity, and the weighting value.
