Abstract

Method of data communication by radio and arrangement therefor, for which prupose use is made of a standardized series interface (1) which, amongst other things, handles standardized TD (Transmitted Data), RD (Received Data), DCD (Data Carrier Detect) and RTS (Request To Send) signals, a transmitter (6), a receiver (7), and a common antenna (9) with a change-over switch (8). The crystal oscillator of the transmitter is modulated directly with the TD signal of the series interface following voltage/frequency conversion. The carrier wave and the level of the MF signal of the receiver (7) are detected in order to obtain the DCD signal of the series interface (1). The level of the LF signal of the receiver (7) is detected and is filtered depending on the received DCD signal and its own RTS signal in order to obtain the RD signal of the series interface (1).
