Wireless communication system

A wireless communication system comprising:

• a plurality of wireless communication devices each including a display unit;
• and
• an information terminal device configured to perform wireless communication with each of the plurality of wireless communication devices,
• wherein the information terminal device includes
• a field intensity calculation unit configured to determine a field intensity of each of the plurality of wireless communication devices,
• a communication device selection unit configured to select at least one wireless communication device of the plurality of wireless communication devices based on each field intensity determined by the field intensity calculation unit,
• a terminal display unit configured to display identification information of the at least one wireless communication device selected by the communication device selection unit,
• a terminal input unit configured to specify one wireless communication device based on the identification information displayed on the terminal display unit, and
• a terminal wireless communication unit configured to perform data communication with the wireless communication device specified on the terminal input unit,
• wherein the communication device selection unit selects the wireless communication device with a largest field intensity among the plurality of wireless communication devices,
• the terminal input unit is configured to receive a rejection operation of rejecting specification of the wireless communication device selected by the communication selection unit, and
• the communication device selection unit is configured to select, when the rejection operation is received by the terminal input unit, the wireless communication device, of which the field intensity is next largest to the field intensity of the wireless communication device that is selected immediately previously.
