Disclosed is an air conditioner system comprising at least one outdoor unit and a plurality of indoor units. The plurality of units may be grouped into one or more groups. A wireless communication module may be provided at each of the plurality of units and configured to perform wireless communication using a Sub-GHz frequency band. The wireless communication module may include an encoder configured to encode a predetermined signal, a modulator configured to modulate the encoded signal according to Orthogonal Frequency Division Multiplexing (OFDM) using multiple subcarriers, at least one antenna having an antenna pattern formed on a Printed Circuit Board (PCB), and configured to output a signal based on the modulated signal, a demodulator configured to demodulate a signal received at the at least one antenna, according to the OFDM, and a decoder configured to decode the demodulated signal. Accordingly, a high-quality wireless communication environment may be implemented.
