Initiated in 2004, the Long Term Evolution (LTE) project focused on enhancing the Universal Terrestrial Radio Access (UTRA) and optimizing 3GPP’s radio access architecture.
Targets were to have average user throughput of three- to four-times the Release 6 HSDPA levels in the Downlink (100Mbps), and two to three times the HSUPA levels in the Uplink (50Mbps).
In 2007, the LTE of the 3rd generation radio access technology – "E UTRA" – progressed from the feasibility study stage to the first issue of approved Technical Specifications. By the end of 2008, these specifications will be sufficiently stable for commercial implementation.
