Abstract

Devices (1,2) for use in frequency hopping systems (3) for frequency hopping through frequencies of a sequence of frequencies get a better overall performance by introducing selectors (4) for selecting the sequence from a number of sequences, which number of sequences comprises a first sequence and a second sequence, which first sequence is longer than the second sequence. Generators (7) generate the first and second sequences. Monitors (5) monitor channels in use and controllers (6) control the selectors (4) for, in a first mode, selecting the first sequence and for, in a second mode, selecting the second sequence in dependence of a monitoring result. Modifiers (8) modify the second sequence. The second sequence may form a subset of the first sequence. This all results in an increased overall quality and a reduced power consumption.
