Abstract
The present invention discloses an apparatus and method for avoiding mutual interference between wireless communication systems. A measurement unit measures the strength of a signal received through a channel to be used in a transmission slot for a switching time of a reception mode and a transmission mode. A judgment unit compares the strength of the received signal with the strength of a reference signal, and judges data transmission. A control unit outputs a signal for performing a transmission operation of the data according to the judgment of the judgment unit. The wireless communication system transmits the data according to the input signal from the control unit. The data transmission is decided by confirming the state of the transmission slot, thereby avoiding collision with a communication apparatus using a frequency identical to a frequency of the channel of the transmission slot.
