IS-2000 is the second generation of
CDMA digital cellular, an extension of
IS-95. It is also known as
CDMA-2000.
The main differences between IS-95 and IS-2000 are: the use of a pilot on the IS-2000 reverse link to permit the use of coherent modulation, and 64 more traffic channels on the forward link that are orthogonal to the original set.
