LTE - Long Term Evolution

Hi All,

     Today, Lets discuss something about the Latest Technology, LTE (Long Term Evolution)

Its a standard for Wireless Communication of High-Speed Data for Mobile Phones and Data Terminals.

The Increase in Usage of Mobile Data Transmission & New Mobile Application such as MMOG (Multi-Media Online Gaming), Mobile TV, Web 2.0, Streaming Contents, Voice-Over-IP (VOIP), have Motivated the 3rd Generation Partnership Project (3GPP) to work on LTE.

The Goal of LTE was to Increase the Capacity & Speed of Wireless Data Networks, Provide Low Latency (delay), Packet Optimized Radio-Access Technology, Supports Flexible Bandwidth using new Digital Signal Processing Techniques and Modulations.

It Supports Scalable Carrier Bandwidths, from 1.4 MHz to 20 MHz and,
Supports both Frequency Division Duplexing (FDD) & Time-Division Duplexing (TDD).

In FDD, Uplink & Downlink Transmission used Different Frequency, while
In TDD, Uplink & Downlink use the Same Carrier (Frequency) & are Separated in Time.

It Redesign & Simplifies the Network Architecture to an IP-based System with significantly reduced Data Transfer Latency.

Its Specification Provides Downlink Peak Rates of 300 Mbit/s, Uplink Peak Rates of 75 Mbit/s.

Advantage :-
  • High Throughput - High Data Rate Transfer can be achieved in both Uplink & Downlink Transmission.
  • Low Latency - Time required to connect to the Network is very less i.e. is in range of few Hundred Milliseconds.
  • Improvement in User Experience - Optimized Signaling for Connection Establishment, Other Air Interface & Mobility Management.
  • Simple Architecture - All Interface between Nodes are IP-based, which Reduces the Operating Cost, & Provides Easy Maintenance.
QoS (Quality of Service) - It supports Hard QoS, with end-to-end quality of service and Guaranteed Bit Rate (GBR) for Radio Bearers. 
Various levels of QoS can be applied to LTE traffic for different applications.

More Updates will be Updated Soon, till than HaPpPpPYyyyy Reading.
