LTE stands for Long Term Evolution,
commonly known as 4G. Mainly it is deployed for High speed data for mobile
phone users with minimal latency less than 5ms. Standard specification is
given by 3GPP(3rd Generation Partnership Project) from release 8 onwards, later
releases standardize for LTE Advanced. LTE
supports wide range of carrier bandwidth from 1.4MHz to 20MHz used by IMT(International
Mobile Telecommunication) system, and supports both mode of duplex
TDD(Time Division Duplex) and FDD(Frequency Division Duplex). LTE network completely based on Packet Switching system, not much rely on circuit switching connection oriented protocols, So this makes it very cost effective and easy to deploy with other existing networks. Even LTE architecture is very simple and comprehensive and designed to support a maximum downlink speed of 300Mbps and maximum uplink speed of 70-75Mbps and promised to enhance up to 1Gbps.
Based on its
internal architecture and QoS supported, It provides dedicated services like
Real time voice/video streaming, real time gaming, high speed data transfer,
Emergency calling system, IMS based calling, High speed browsing and addition
features like MBMS.
