Method for selecting operating frequency channels in a wireless communication system

A method for selecting operating frequency channels for a network communicating data over a shared medium, the network being configured to communicate within a frequency range, the method comprising:

• i) dividing the frequency range into a plurality of frequency channels (f1-fn), each frequency channel defining predetermined frequency parameters;
• ii) dividing data to be communicated over the network into sequences (FS), each sequence having a plurality of positions (SP1-SPm);
• iii) regularly scanning the frequency range to identify interfering frequencies within the frequency range generated by interfering networks operating within the shared medium;
• iv) assigning a frequency channel (fk) to each position (SPi) within a current sequence based on the interfering frequencies identified in step iii), whereby the use of interfering frequencies is limited;
• defining a default frequency channel, having default frequency parameters, for each position in the current sequence;
• v) primarily selecting the frequency channel (fk) assigned to a position (SPi) in the current sequence in step iv) to be the default frequency channel, if the identified interfering frequencies in step iii) are non-overlapping with the default frequency parametersand
• vi) secondarily selecting the frequency channel (fk) assigned to a position (SPi) in the current sequence in step iv) to be a non-default frequency channel if the identified interfering frequencies in step iii) are non-overlapping with the frequency parameters of the non-default frequency channel.
