A method of performing an operation related to a second device, performed by a first device, via near field wireless communication, and an apparatus therefore. When a signal for wireless communication is received from the second device, the method includes calibrating the strength of the received signal; comparing the strength of the calibrated signal with operation signal information that is a result of calibrating a range of strengths of signals which are for the wireless communication and which are received from the second device moving between a plurality of points set to be within a predetermined distance from the first device; and as a result of the comparison, selectively performing the operation related to the second device.
