LTE | Long Term Evolution

What is LTE | Long Term Evolution?
LTE | Long Term Evolution is A communication standart wireless high-level data access based on GSM / EDGE and UMTS / HSPA where there was an increase in capacity and speed using a new modulation technique.

The format was first proposed LTE by NTT DoCoMo of Japan and has been adopted as an international standart. LTE service was first opened by the company TeliaSonera in Stochholm and Oslo on December 14, 2009. United States and Japan in 2010.

LTE network are expected to release first deployed globally in the next year as natural evolution of several 2G and 3G systems, including global system for mobile communications (GSM) and UMTS, 3GPP, and 3GPP2.

LTE network is to increase the capacity and speed of wireless data networks using techniques DSP (Digital Signal Processing) and modulation are developed.

As a high-level technology, LTE is capable of fetching up to speeds of up to 300 Mbps and 75Mbps upload. LTE supports scalable carrier bandwidth, and supports frequency division duplexing (FDD) and time division duplex (TDD).

LTE network architecture is a flat IP architecture based network, called the Evolved Packet Core (EPC), which is designedto replace the GPRS Core Network and support the seamless exchange for voice and data compared with earlier network technologies exist such as GSM, UMTS, and CDMA 2000 .

Excess LTE network:
  • Download rates up to 299.6 Mbit/s with upload rates 75.4 Mbit/s on user equipment category.
  • Improved support for mobility.
  • Support for all frequency bands currently used by the IMT system by ITU-R.
  • Support for MBSFN, this feature can provide services such as Mobile TV using LTE infrastructure, and is a competitor to DVB-H service-based TV broadcasting.
