Overview of 3GPP Lont Term Evolution - 1365 Words

An Introduction of Overview of 3GPP LTE (Long Term Evolution) Long Term Evolution (LTE) is 4G wireless communications standard radio platform technologies that allow operators to achieve higher peak throughputs than HSPA+ in higher spectrum bandwidth. LTE was developed by the 3rd Generation Partnership Project (3GPP), and this began in 2004, with an official LTE work item started in 2006 and a completed 3GPP Release 8 specification in March 2009. Initial deployments of LTE began in late 2009, and it is part of the GSM evolutionary path for mobile broadband, following EDGE, UMTS, HSPA (HSDPA and HSUPA combined) and HSPA Evolution (HSPA+). Although HSPA and its evolution are strongly positioned to be the dominant mobile data technology for the next decade, the 3GPP family of standards must evolve toward the future. HSPA+ will provide the stepping-stone to LTE for many operators. The overall objective for LTE is to provide an extremely high performance radio-access technology that offers full vehicular speed mobility and that can readily coexist with HSPA and earlier networks. Because of scalable bandwidth, operators will be able to easily migrate from their networks and users from HSPA to LTE over time. LTE assumes a full Internet Protocol (IP) network architecture and is designed to support voice in the packet domain. It incorporates top-of-the-line radio techniques to achieve performance levels beyond what will be practical with CDMA approaches, particularly in larger
