PURPOSE:To attain low power consumption, miniaturization, and the improvement of throughput by receiving and detecting a control signal and an identification code from a base station by a terminal station, and modulating and reflecting data from the base station based on a detection result. CONSTITUTION:This system is composed in such a way that a local area network(LAN) for radio forms one network with the base station 11 connected to an external communication line 10 and the terminal station 12(12a-12c), and a radio unit 13(13a-13c) is connected to the terminal station 12, thereby, the transfer of the data by radio can be performed between the base station 11. The base station 11 generates and transmits a connection signal to inquire the presence/absence of the transmission request of the data and the identification codes of the terminal stations 12a-12c to the terminal stations 12a-12c according to sequence decided in advance, and the terminal stations 12a-12c receive and detect the connection signal and the identification number transmitted from the base station 11, and after that, modulate and reflect the data sent from the base station 11 based on the detection result. |
