1. A method of establishing a set of piconets comprising:
generating a set of codes, wherein each code corresponds to a sequence of dwell times and bands, wherein the sequence includes at least one group of dwell times;
assigning codes to the piconets in the set of piconets, wherein:
each piconet in the set of piconets has a unique code compared to the other piconets in the set of piconets, wherein the unique code is a member of the set of codes; and
during a time span, any two different piconets in the set of piconets are capable of using one or more same bands for a collective time for each group of dwell times, no longer than the longest dwell time within such group of dwell times; and
substituting an extra band for an existing band, wherein before substituting, the unique codes do not correspond to the extra band.
