LTE is based on the 2G GSM / EDGE and 3G UMTS / HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks.
LTE Mobile communicates with just one base station and one cell at a time and there are following two main functions supported by eNB: The eBN sends and receives radio transmissions to all the mobiles using the analogue and digital signal processing functions of the LTE air interface.
Much of the LTE standard addresses the upgrading of 3G UMTS to what will eventually be 4G mobile communications technology. A large amount of the work is aimed at simplifying the architecture of the system, as it transitions from the existing UMTS circuit + packet switching combined network to an all-IP flat architecture system.
Users can start a call or transfer of data in an area using an LTE standard, and, should coverage be unavailable, continue the operation without any action on their part using GSM/ GPRS or W-CDMA-based UMTS or even 3GPP2 networks such as cdmaOne or CDMA2000. Uplink and downlink Carrier aggregation. Packet-switched radio interface.
