Abstract:
1. A method of measuring a location of a communication terminal, the method comprising: storing location coordinates of a plurality of access points and a location coordinate of a lamp in a storage unit; receiving from the communication terminal identity information that identifies nearby access points from among the plurality of access points and identity information that identifies the lamp; extracting a location coordinate of each of the nearby access points from the storage unit, and calculating the location of the communication terminal using the extracted location coordinates; and correcting the calculated location using the location coordinate of the lamp, as a final location coordinate of the communication terminal, wherein the correcting comprises: selecting a correction ratio based on a number of extracted location coordinates; and determining a location coordinate where a straight line connecting a calculated location coordinate and the location coordinate of the lamp is divided into the correction ratio, as the final location coordinate of the communication terminal.
