A method to determine an optimum receiving device, which receives a signal outputted from a separate device through wireless communication, among a plurality of communication devices two-dimensionally arranged on a two dimensional diffusive signal-transmission board, the plurality of communication devices being configured to communicate with each other using a two dimensional diffusive signal-transmission technology, the method includes first selecting a first plurality of receiving devices, of which received signal intensities are to be measured, among the plurality of communication devices, first measuring the received signal intensities of the first plurality of receiving devices, first comparing the received signal intensities of the first plurality of receiving devices, second selecting a second plurality of receiving devices based on the results of the first comparing the received signal intensities, second measuring the received signal intensities of the second plurality of receiving devices, second comparing the received signal intensities of the second plurality of receiving devices, and determining the optimum receiving device based on the results of the second comparing the received signal intensities.
