Patent ID: 8363694

Claim:
A method comprising: partitioning, at a first access point, a set of hopping carrier frequencies into disjoint sets including a first set and a second set such that a frequency correlation between a first hopping carrier frequency of the first set and a second hopping carrier frequency of the second set is approximately zero, wherein the first set includes odd frequencies of the set but excludes even frequencies of the set, and wherein the second set includes the even frequencies of the set but excludes the odd frequencies; generating at least one copy of a signal, the signal comprising a plurality of time division multiple access frames, the at least one copy of the signal having a fixed delay and a random phase relative to the signal; and when the first access point is operating in a first operating mode, transmitting the signal and the at least one copy of the signal using selected hopping carrier frequencies from the first and second sets such that a time division multiple access frame is sent using the first hopping carrier frequency from the first set and an adjacent second frame is sent using the second hopping carrier frequency from the second set, wherein, when the first access point is operating in the first operating mode, transmitting the signal and the at least one copy of the signal includes transmitting even framers of the plurality of time division multiple access frames using frequencies of the first set and odd frames of the plurality of time division multiple access frames using frequencies of the second set while a second access point transmits even time division multiple access frames using the frequencies of the second set and odd time division multiple access frames using the frequencies of the first set.
