In a wireless communications system which hops from frequency to frequency, rather than hopping according to a fixed dwell interval and a pre-determined pseudo-random hop sequence, a quality-based frequency hopping methodology is defined in which a new frequency is hopped to when the channel quality on the current frequency degrades based on the measured value or values of one or more predetermined metrics that are associated with channel quality. When triggered to hop to a next frequency, the hop-to-frequency may be the next frequency in the pseudo-random hop sequence known to both the transmitter and receiver or, in order to improve the reliability of communications, may be determined based on channel quality measurements on different potential hop-to-frequencies.
