Welcome to LTE Encyclopedia; your one stop resource for all   information   related to the 3GPP  LTE standard
3GPP  Long   Term   Evolution  (LTE),  is  the  latest standard   in   the   mobile network technology tree that produced the GSM/EDGE  and  UMTS/HSxPA network technologies.  It   is   a   project   of  the 3rd Generation Partnership Project (3GPP),   operating   under a name trademarked   by one of the   associations   within   the partnership ,     the   European     Telecommunications Standards Institute.

LTE Systems Overview

Long Term Evolution (LTE) is the  latest step in  moving forward   from the cellular  3G  services  ( e.g.   GSM to UMTS to HSPA to LTE or CDMA to LTE). LTE is based on   standards    developed    by   the   3rd   Generation Partnership Project (3GPP).  LTE may also be  referred more   formally   as  Evolved   UMTS   Terrestrial  Radio Access (E-UTRA) and Evolved UMTS  Terrestrial  Radio Access  Network   (E-UTRAN).    Even   though   3GPP created   standards   for   GSM/UMTS   family, the LTE standards are completely new, with exceptions where it made sense. The following are the main objectives for LTE.
  • Increased downlink and uplink peak data rates.
  • Scalable bandwidth
  • Improved spectral efficiency
  • All IP network
  • A standard’s based interface that can support a multitude of user types.

LTE networks are intended to bridge the functional data exchange   gap   between   very  high  data  rate   fixed wireless   Local   Area   Networks  (LAN)  and very high mobility cellular networks.
