The invention relates to an arrangement for optimizing the data transmission
over a bidirectional radio channel. According to the invention, the digital data
to be transmitted according to a data transmission protocol is divided into individual
data packets in each of two transmitting/receiving stations. In each transmitting/receiving
station, the number and/or priority and/or type (e.g. information, control characters,
repeat blocks) of the data packets generated by the data transmission protocol
of the higher level and transmitted to the respective transmitter of the station
is determined (data packet identifications). According to the data packet identifications,
the data transmission protocol is then selected in at least one of the stations
in accordance with an optimum utilization of the radio channel capacity.
