CDMA rose to become one of the two competing communication standards in the world today by resorting to extensive randomization which insures that the underlying hardware will operate at maximum efficiency, expressed through randomized throughput, which then is decoded for each user as if he or she were the only ones with messages carried through. By compressing data to its randomized equivalent, its size is minimized, and its communication optimized. Unrandomized data is less efficient in transport, and slower in transaction. Come to think about it, every conversation, video, website flowing into your Verizon phone is not only digitized (every system does that), it is randomized: the contents bits are XORed with a pseudo-random stream, to generate a pseudo-random output, which is subsequently de-randomized at the receiving end.

The setup is the same as in cryptography: pattern is randomized to be handled efficiently, and is de-randomized at the receiving end where the pattern shows up again. Randomness is rising in modern communication!
