Patent ID: 8711899

Claim:
A method for determining a set of frequencies which may be used in a frequency plane, for the transmission of information between at least two radio transceivers of a same network operating with frequency hopping, the method comprising: determining an initial set of frequencies which may be used, each frequency of the initial set having a variable quantity with a value below a comparison threshold; monitoring first and second portions of the frequency plane, the first monitored portion including the set of the frequencies which may be used, determined at the end of the previous determination step, the second monitored portion including frequencies not belonging to the set of the frequencies which may be used, determined at the end of the previous determination step; and subsequently determining a new set of frequencies which may be used associated with at least one of the monitored portions, each frequency of the new set having a variable quantity with a value below a comparison threshold associated with this subsequent determination step, wherein a step of monitoring the first and second portions and the subsequent determination step are performed automatically by a transceiver, wherein the subsequent determination step associated with the first monitored portion has a first comparison threshold and in that the subsequent determination step associated with the second monitored portion has a second comparison threshold with a value distinct from that of the first comparison threshold, wherein a frequency of the first monitored portion is suppressed from the new set of frequencies which may be used only when the value of its variable quantity is greater than the first threshold during a plurality of successive measurements.
