WebGold sequences are in useful in non-orthogonal CDMA. (CDMA 2000 is mostly an orthogonal CDMA system) Gold sequences have only three cross-correlation peaks, which tend to get less important as the length of the code increases. They also have a single auto-correlation peak at zero, just like ordinary PN sequences.
