INDOOR WIRELESS POSITIONING SYSTEM AND INDOOR WIRELESS POSITIONING METHOD

摘要

Provided are an indoor wireless positioning system and method capable of more accurately performing indoor wireless positioning by predicting signal attenuation due to a floor or wall within a multi-floor building. The indoor wireless positioning method includes calculating floor loss information of a floor on which the user terminal is located within the building, a higher floor, and a lower floor, calculating the floor on which the user terminal is located by comparing the calculated floor loss information to pre-stored previous floor loss information, calculating information about wall loss in the floor on which the user terminal is located, and acquiring position information on a horizontal plane of the user terminal according to received signal strength of the user terminal and the information about the wall loss. When the position of the user terminal is detected, detection accuracy is improved and more efficient wireless positioning is possible.
