3 GPP . (3rd Generation Partnership Project) is a partnership in mobile phone technology which was established in December of 1998 . This cooperation is between ETSI ( Europe ), ARIB / TTC ( Japan ), CCSA ( China ), ATIS ( North America ) and TTA ( South Korea ).

One of its most important features has been HSDPA (High Speed downlink packet access). HSDPA represents an advance in WCDMA to achieve higher data transmission speeds. It will allow updating the existing architecture to launch high-speed services with a minimum investment.
The 3GPP identifies three phases in the evolution of HSDPA:
- First, “Basic HSDPA”, defined in Release 5 that allows typical data rates of 10.8Mbit / s (maximum of 14.4Mbit / s).
- The second phase incorporates intelligent antennas and HSUPA and the third phase already contemplates the combination of OFDM and MIMO. This phase, developed in the RAN LTE study group, predicts data transmission rates of 100 Mbps in the downlink through the use of multiple antennas with spatial multiplexing.
The objective of 3GPP is to extend to the entire planet third-generation 3G applications (mobile phone) with ITU’s IMT-2000 system specifications. 3GPP systems are based on the evolution of GSM systems , now commonly known as UMTS systems . 3GPP can be confused with 3GPP2 whose standard is based on IS-95 technology, commonly known as CDMA2000.
