The 3rd Generation Partnership Project (3GPP) standardized wireless technology Long Term Evolution (LTE). 3GPP is a consortium of several institutes.
The project also defines standards for other mobile technologies such as HSPA. In December 2009, the Release 9 followed as the second standard, which contained LTE after the year before the release had 8 defines first LTE.
Four independent antennas
LTE Release 9 help you reach computationally up to 326.4 Mbit/s for receiving data (download) and up to 86.4 Mbit/s for sending data (upload).
Compared to 172.8Mbit/s download, which can be reached with Release 8, the theoretical speed was almost doubled. These Technologies make it more possible. As with Release 8, a 16-fold quadrature amplitude modulation (QAM) is used, a technology that enables more data to be carried on a shaft.
In addition, up to 20 MHz frequency bandwidth used. However, Release 9 is used in contrast to its predecessor up to four independent antennas at the transmitter as the receiver; the same send or receive data. This technology is called MIMO (Multiple Input Multiple Output).
