1. A wireless communication system comprising:
a first communication module; and
at least one second communication module wirelessly connected to the first communication module,
wherein the first communication module is wirelessly connected to the second communication module to which driving power is applied from a same power source as that of the first communication module,
wherein the first communication module is wirelessly connected to the second communication module after performing identification based on identification data including real time clock (RTC) data generated by real time clock (RTC) modules of the first and second communication modules, the real time clock data modules being simultaneously applied with the driving power from the same power source, and
wherein the identification is performed by reading out time information from the real time clock (RTC) data of the second communication module and identifying whether the real time clock (RTC) data is within an error margin of time information of the first communication module.
