ABSTRACT:
A radio data communication device that can perform a packet communication with the packet configuration suitable for transmission of a large volume of data in packet communications utilizing a low rate transmission mode and a high rate transmission mode. The transmitter side transmits packets only in a low rate mode or in a high rate mode after transmission in a low rate mode or only in a high rate mode. The receiver side simultaneously demodulates packets in the low rate mode and the high rate mode to detect the synchronous signal for each mode and judges whether or not in which mode the data has been transmitted, thus selecting the successive receive mode.
