Maharsh Shah, M.S in Telecommunications, Southern Methodist University The evolution of 3G technologies and system into 4G evolution is driven by the development and creation of latest and upgraded services for the mobile devices, and is enabled by this similar advancement for the respective mobile systems. The development of LTE and LTE-Advanced technologies, with Advanced specifying the only difference between LTE release 10 /LTE Advanced and ITU/IMT-Advanced. The work on developing these technologies- LTE and LTE Advanced is performed as an ongoing continuous task within the 3GPP, the same organization the developed the first 3G system namely WCDMA and HSPA. The process for defining IMT Advanced was set by ITU-R WP5D(Working†¦show more content†¦The Release 10 of LTE is the version that is approved by the ITU-R as an IMT Advanced technology and so is called LTE-Advanced. Release 10 of the LTE that came out in March 2011 included carrier aggregation, enhanced downlink MIMO, uplink MIMO, enhanced ICIC and advanced relays. Following the Release 10 came the Release 11 that incorporated enhanced carrier aggregation and additional intra-band carrier aggregation. In 2008 the work associated with IMT-Advanced within the ITU-R circulated the detailed requirements and process via a circular letter. For 3GPP, LTE advanced is not a new technology but is an evolutionary step in the ongoing development of LTE. To reach the IMT Advanced standards, wider bandwidth by aggregation of various multiple carriers and evolved use of advanced antenna techniques in both downlink and uplink are the two main phenomenon added in the Release 10 of LTE. Th e transmission scheme used for this technology is called OFDM (Orthogonal Frequency Division Multiplexing) which is also prevalent in other radio-access technologies like WiMax and DVB broadcasting technologies. The work on LTE started in the late 2004 with the aim of providing new radio access technology that focused on packet switched data. The tasks include user/system, throughput, peak data rates, spectral efficiency and user plane latency. ITU defined a set of requirements for IMT Advanced which include support for aShow MoreRelatedThe Human Heart Is A Muscular Organ That Provides A Continuous Blood Circulation1837 Words   |  8 PagesTechnique:-[3] Fig:5 SD1: dispersion (standard deviation) of points perpendicular to the axis of line of identity SD2: dispersion (standard deviation) of points along the axis of line of identity SDRR: standard deviation of the RR intervals SDSD: standard deviation of the successive differences of the RR intervals WHAT ARE THE ADVANTAGES OF POINCARE PLOTTING? ï‚ § Simple visualization tool ï‚ § Outlier (ectopic beat or artifact) identifier ï‚ § Possible insights into short term and long termRead MoreMarketing Plan for Milk Tea7890 Words   |  32 Pageshttp://www.geocities.com/hello_tai_tai/bubbletea.html.
