ABSTRACT:
A wireless communication system includes a repeater and a terminal device. The terminal device is connected to the repeater via a wireless communication channel. The terminal device includes a first section for converting a first electric signal into a first wireless signal, and transmitting the first wireless signal toward the repeater along the wireless communication channel. The terminal device includes a second section for receiving a second wireless signal from the repeater via the wireless communication channel, and converting the second wireless signal into a second electric signal. The terminal device includes a third section for deciding whether or not the first electric signal and the second electric signal are equal to each other to detect whether or not a signal collision occurs on the wireless communication channel.
