Mobile terminal, method of computing absolute coordinates of wireless AP by mobile terminal, and system of computing absolute coordinates of wireless AP using mobile terminal

摘要

A mobile terminal capable of receiving a radio signal from a wireless access point (AP) and a method of computing absolute coordinates of a wireless AP thereof are provided. The mobile terminal includes: a main body; a location information unit mounted in the main body and collecting absolute coordinates of the main body; a wireless communication unit computing relative distance information between an external wireless access point (AP) and the main body by using radio signals transmitted and received between the wireless AP and the main body; a detection unit detecting relative coordinates of the main body by using the distance information and relative coordinates of the wireless AP; and a controller computing absolute coordinates of the wireless AP.
