identifying a characteristic of the moving object associated with signal loss in the area; and
identifying a propagation characteristic of a signal transmitted between the first position and the second position based on the characteristic of the moving object,
wherein the characteristic of the moving object is associated with at least one of a size, a material, or a moving pattern of the moving object.

2. The method of claim 1 , further comprising:
identifying a three-dimensional object associated with the signal loss according to the characteristic of the moving object; and
identifying the propagation characteristic of the signal transmitted between the first position and the second position based on the three-dimensional object.

3. The method of claim 1 , wherein the characteristic of the moving object is associated with at least one of a speed of the moving object and a number of objects that have passed on the area per unit time.
