ABSTRACT:
In a method for qualification of the transmission quality of a frequency channel in a wire-free communication system that has two or more frequency channels, units in the system communicate via the frequency channels. Data is transmitted in time slots in a time pattern using a time slot method. The influence of possible interference sources is determined in a measurement time slot in which no data is received, in that the field strength is measured at the frequencies of two or more frequency channels, and the field strength information is used for qualification decisions relating to the frequency channels.
