LTE AdvancedFrom Wikipedia, the free encyclopediaLTE Advancedis
amobile communication standardand a major enhancement of theLong
Term Evolution(LTE) standard. It was formally submitted as a
candidate4Gsystem toITU-Tin late 2009 as meeting the requirements
of theIMT-Advancedstandard, and was standardized by the3rd
Generation Partnership Project(3GPP) in March 2011 as 3GPP Release
10.[1]Contents[hide] 1Background 2Proposals 3Timeframe and

notes)Background[edit]TheLTEformat was first proposed byNTT
DoCoMoofJapanand has been adopted as the international
standard.[2]LTE standardization has matured to a state where
changes in the specification are limited to corrections andbug
fixes. The first commercial services were launched
inSwedenandNorwayin December 2009[3]followed by the United States
and Japan in 2010. More LTE networks were deployed globally during
2010 as a natural evolution of several 2G and 3G systems,
includingGlobal system for mobile communications(GSM) andUniversal
Mobile Telecommunications System(UMTS) (3GPPas well as3GPP2).The
work by3GPPto define a4Gcandidate radio interface technology
started in Release 9 with the study phase for LTE-Advanced. Being
described as a3.9G(beyond 3G but pre-4G), the first release of LTE
did not meet the requirements for4G(also calledIMT Advancedas
defined by theInternational Telecommunication Union) such as peak
data rates up to 1Gb/s. The ITU has invited the submission of
candidate Radio Interface Technologies (RITs) following their
requirements in a circular letter, 3GPP Technical Report (TR)
36.913, "Requirements for Further Advancements
forE-UTRA(LTE-Advanced)."[4]These are based on ITU's requirements
for4Gand on operators own requirements for advanced LTE. Major
technical considerations include the following: Continual
improvement to the LTE radio technology and architecture Scenarios
and performance requirements for working with legacy radio
technologies Backward compatibility of LTE-Advanced with LTE. An
LTE terminal should be able to work in an LTE-Advanced network and
vice versa. Any exceptions will be considered by3GPP. Consideration
of recentWorld Radiocommunication Conference(WRC-07) decisions
regarding frequency bands to ensure that LTE-Advanced accommodates
the geographically available spectrum for channels above 20MHz.
Also, specifications must recognize those parts of the world in
which wideband channels are not available.Likewise, 'WiMAX 2',
802.16m, has been approved by ITU as theIMT Advancedfamily. WiMAX 2
is designed to be backward compatible with WiMAX 1 devices. Most
vendors now support conversion of 'pre-4G', pre-advanced versions
and some support software upgrades of base station equipment from
3G.The mobile communication industry and standards organizations
have therefore started work on 4G access technologies, such as LTE
Advanced. At a workshop in April 2008 in China, 3GPP agreed the
plans for work on Long Term Evolution (LTE).[5]A first set of
specifications were approved in June 2008.[6]Besides the peak data
rate 1Gb/sas defined by the ITU-R, it also targets faster switching
between power states and improved performance at the cell edge.
Detailed proposals are being studied within theworking
groups.Proposals[edit]The target of 3GPP LTE Advanced is to reach
and surpass theITUrequirements. LTE Advanced should be compatible
with first release LTE equipment, and should share frequency bands
with first release LTE. In the feasibility study for LTE
Advanced,3GPPdetermined that LTE Advanced would meet
theITU-Rrequirements for4G. The results of the study are published
in3GPPTechnical Report (TR) 36.912.[7]One of the important LTE
Advanced benefits is the ability to take advantage of advanced
topology networks; optimized heterogeneous networks with a mix of
macrocells with low power nodes such aspicocells,femtocellsand new
relay nodes. The next significant performance leap in wireless
networks will come from making the most of topology, and brings the
network closer to the user by adding many of these low power nodes
LTE Advanced further improves the capacity and coverage, and
ensures user fairness. LTE Advanced also introduces multicarrier to
be able to use ultra wide bandwidth, up to 100MHz of spectrum
supporting very high data rates.In the research phase many
proposals have been studied as candidates for LTE Advanced (LTE-A)
technologies. The proposals could roughly be categorized into:[8]
Support for relay node base stations Coordinated multipoint (CoMP)
transmission and reception UE Dual TX antenna solutions
forSU-MIMOand diversityMIMO, commonly referred to as 2x2 MIMO
Scalable systembandwidthexceeding 20MHz, up to 100MHz Carrier
aggregation of contiguous and non-contiguous spectrum allocations
Local area optimization ofair interface Nomadic / Local Area
network and mobility solutions Flexiblespectrum usage Cognitive
radio Automatic and autonomous network configuration and operation
Support of autonomous network and device test, measurement tied to
network management and optimization Enhancedprecodingandforward
error correction Interference management and suppression Asymmetric
bandwidth assignment forFDD HybridOFDMAandSC-FDMAin uplink UL/DL
intereNBcoordinated MIMO SONs, Self Organizing Networks
methodologiesWithin the range of system development, LTE-Advanced
and WiMAX 2, can use up to 8x8 MIMO and 128 QAM in downlink
direction. Example performance: 100MHz aggregated bandwidth,
LTE-Advanced provides almost 3.3Gbit peak download rates per sector
of the base station under ideal conditions. Advanced network
architectures combined with distributed and collaborative smart
antenna technologies provide several years road map of commercial
enhancements.A summary of a study carried out in 3GPP can be found
in TR36.912.[9]Timeframe and introduction of additional
features[edit]Original standardization work for LTE-Advanced was
done as part of 3GPP Release 10, which was frozen in April 2011.
Trials were based on pre-release equipment. Major vendors support
software upgrades to later versions and ongoing improvements.In
order to improve the quality of service for users in hotspots and
on cell edges, heterogenous networks (HetNet) are formed of a
mixture of macro-, pico- and femto base stations serving
corresponding-size areas. Frozen in December 2012, 3GPP Release
11[10]concentrates on better support of HetNet. Coordinated
Multi-Point operation (CoMP) is a key feature of Release 11 in
order to support such network structures. Whereas users located at
a cell edge in homogenous networks suffer from decreasing signal
strength compounded by neighbor cell interference, CoMP is designed
to enable use of a neighboring cell to also transmit the same
signal as the serving cell, enhancing quality of service on the
perimeter of a serving cell. In-device Co-existence (IDC) is
another topic addressed in Release 11. IDC features are designed to
ameliorate disturbances within the user equipment caused between
LTE/LTE-A and the various other radio subsystems such as WiFi,
Bluetooth, and the GPS receiver. Further enhancements for MIMO such
as 4x4 configuration for the uplink were standardized.The higher
number of cells in HetNet results in user equipment changing the
serving cell more frequently when in motion. The ongoing work on
LTE-Advanced[11]in Release 12, amongst other areas, concentrates on
addressing issues that come about when users move through HetNet,
such as frequent hand-overs between cells.Technology

Devices[edit]Main article:List of devices with LTE AdvancedAt
the time of its launch in 2007, LTE-A didn't have compatibility
with anySmartphone, but only with a small amount of 4G LTE Routers.
The first LTE-A capable mobile phone or tablet, wouldn't arrive
until late 2013. While no phone is capable of 1 Gbit/s+, there are
phones that can reach 300 Mbit/s to 500 Mbit/s under ideal
conditions. Requirements are that the device must either have 3GB+
ofRAM, a 32-bitQuad core/Octacore processor, and multiple 4G-LTE
antennas or a 64-bitDualcore/Quad coreprocessor with 1GB+ of RAM
and at least two 4G-LTE antennas.ManufacturerNameMax Download
