CDMA is actually a digital cellular technology that uses spread spectrum techniques to allow multiple end users to share the exact same frequency band, allowing more efficient use of the readily available spectrum.

DSSS is Direct Sequence Spread Spectrum System which can be a spread spectrum approach by which the data to be transmitted is encoded making use of spreading code and acquired after which decoded utilizing the exact same code.

In case the 3GPP2 doc you are looking for won't seem in any with the lists higher than, it should be beneath progress. Paperwork nearing the ultimate phases of the development procedure are explained to generally be going through validation and verification "V and V".

HSPA provides major advancements in data speeds, permitting end users to obtain and upload data far more promptly than with past 3G systems.
