1. A method of channel hopping in a radio communications systems wherein channel hopping is effected between channels for connections between a base station and at least one mobile station in the radio communications system, and wherein the connections are subjected to signal attenuation and interference, said method comprising the steps of:

  • generating a signal attenuation parameter for the respective connections, wherein said signal attenuation parameter corresponds to the extent by which a desired signal has been attenuated when it is transmitted from a transmitter until it is received by a receiver;

    generating a channel quality parameter for the respective channels;

    generating at least one channel hop sequence for the respective connections, wherein a channel hop sequence includes a number of channels between which the connection hops, and wherein a channel hop sequence is generated in accordance with the signal attenuation parameter of the connections and the channel quality parameter of said channels, wherein the better a connection is with regard to the signal attenuation parameter, the poorer the channels will be with regard to the channel quality parameter in the channel hop sequence for that connection;

    allocating the channel to a respective hop sequence list in the base station and in the mobile stations; and

    channel hopping between the channels in the channel that have been allocated to the hop sequence lists when communicating by radio on the connections between the base station and the mobile stations.
