Channel qualification for an adaptive frequency hopping method by means of bit or packet error rate measurement and simultaneous field strength measurement

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.
