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 Release 10, LTE advanced is outlined, 9 expansion of LTE in Release 8 and Release 10 was introduced in 2009 as a proposal and completed in 2011.
100 Megahertz needed
The first 4th generation wireless technology, LTE advanced theoretically reaches up to 1 gigabit per second (GB/S) for receiving data (download) and up to 500 megabit per second (Mbit/S) for sending data.
Just like LTE in Release 8 and 9 uses LTE advanced is a 16-fold quadrature amplitude modulation (QAM), a technology that allows more data to be transported on a wave.
In contrast to the previous technologies, LTE advanced 100 Megahertz is used to frequency bandwidth, which can be summarized from independent frequency bands. This is necessary, because no operator called integrated 100 MHz of LTE frequencies into his own. This frequency bandwidth is shared by eight independent antennas, which must be installed at the transmitter as at the receiver. This technology is referred to 8 x 8 MIMO (Multiple Input Multiple Output).
