摘要：
Provided is a fingerprint database generating method and device for wireless location. Signal strength is estimated by using access points on a numerical map, position coordinates of grid points, and a radio wave attenuation model so as to generate a fingerprint database. A simulation error is computed based on actual survey data measured in the real space, and the estimated signal strength is corrected by using the computed simulation error to thus generate a fingerprint database.
