    摘要: In a method for qualification of a frequency channel in a wire-free communication system, data is transmitted on different frequency channels by means of an adaptive frequency hopping method. The transmission and reception are carried out in time slots using a time slot method which is based on the radio standard. In order to qualify the transmission quality of the frequency channels, data packet error rates and/or bit error rates and the field strength of the received data signal are measured, and the measured field strength is compared with a threshold value field strength in order to make a selection decision.

    摘要: A packet-oriented mobile radio transmission system takes account of a packet utilization level that indicates how much of the maximum amount of payload information that can be transmitted is used for transmission. Such packet utilization level is a function of the packet type. A packet type that is suitable in the respective reception conditions is selected at the receiving end as a function of a variable that is characteristic of the integrity of the received data, and of the packet utilization level. At the transmission end, the packet type is switched as a function of the selection result.
