3rd Generation Partnership Project (3GPP) is a partnership mobile technology, which was established in in December 1998. This cooperation is between ETSI (Europe), ARIB / TTC (Japan), CCSA (China), ATIS (North America) and TTA (Korea South).
One of its most important features has been introduced HSDPA (High Speed Downlink Packet Access). HSDPA represents an advance in WCDMA for higher data transmission speeds. allow update the existing architecture to launch high-speed services with minimal investment. 3GPP has identified three phases in the evolution HSDPA. First, "basic HSDPA," defined in the release 5 which allows data rates typical of 10.8Mbit / s (maximum 14.4Mbit / s). The second phase includes HSUPA smart antennas and the third phase and includes the combination of OFDM and MIMO. This phase developed in the LTE RAN study group, predicts data transmission rates 100 Mbps on the downlink using multiple antennas with spatial multiplexing.
