Abstract
Provided is a method of measuring a terminal position using a tag and a terminal thereof. A first terminal measures a first position by reading a tag having a predetermined position, and a position change is continuously detected using a sensor to measure a changed second position. When the first terminal or a second terminal wirelessly communicates each other, communication power strength is gradually changed, minimum communication power strength capable of communicating is measured, and the first or second terminal measures a third position of the second terminal based on the second position in consideration of a communication range according to the minimum communication power strength. As a result, it is possible to accurately determine a terminal position.
