The LTE technology as specified within 3GPP Release 8 was first commercially deployed by the end of 2009. Since then, the number of commercial networks is strongly increasing around the globe and LTE has become the fastest developing mobile system technology. Like all cellular technologies, LTE is continuously worked on in terms of improvements. 3GPP groups added technology components into so called "releases". Initial enhancements were included in the 3GPP Release 9, followed by more significant improvements in 3GPP Release 10, also known as LTE-Advanced. Beyond Release 10, a number of different market terms have been used. However 3GPP reaffirmed that the naming for the technology family and its evolution continues to be covered by the term LTE-Advanced. i.e. LTE-Advanced remains the correct description for specifications defined from Release 10 onwards, including 3GPP Release 12. This white paper summarizes improvements specified in 3GPP Release 11.
