CDMA: Direct Sequence (DS) vs. Frequency Hopping (FH)
	n FH has potentially less total interference: – ratio of intracell-to-intercell interference is two to one – no intracell interference in FH case n no power control necessary to ensure all signals are received at base with equal strength n external jamming potentially handled more gracefully by FH n DS requires contiguous wide band, FH spectrum does not have to be contiguous n FH has somewhat more complex radio control
