LTEOver View3GPP EvolutionRelease 99 (Mar. 2000): UMTS/WCDMARel-5 (Mar. 2002): HSDPARel-6 (Mar. 2005): HSUPARel-7 (2007): DL MIMO, optimized real-time services (VoIP, gaming, )Long Term Evolution (LTE) 3GPP work on the Evolution of Mobile System started in November 2004. Standardized in the form of Rel-8. Spec finalized and approved in January 2008.LTE-Advanced study phase in progress.

Page 3LTE Background IntroductionWhat is LTELTE (Long Term Evolution) is known as the evolution of radio access technology conducted by 3GPP. The radio access network will evolve to E-UTRAN (Evolved UMTS Terrestrial Radio Access Network), and the correlated core network will evolved to SAE (System Architecture Evolution).

What can LTE doFlexible bandwidth configuration: supporting 1.4MHz, 3MHz, 5MHz, 10Mhz, 15Mhz and 20MHzPeak date rate (within 20MHz bandwidth): 100Mbps for downlink and 50Mbps for uplinkTime delay:
