An acronym for L ong T erm E volution, LTE is a 4G wireless communications standard developed by the 3rd Generation Partnership Project (3GPP) that's designed to provide up to 10x thespeeds of 3G networks for mobiledevices such as smartphones , tablets , netbooks , notebooks and wireless hotspots. 4G technologies are designed to provide IP -based voice, data and multimedia streaming at speeds of at least 100 Mbit per second and up to as fast as 1 GBit per second. 4G LTE is one of several competing 4G standards along with Ultra Mobile Broadband ( UMB ) and WiMax (IEEE 802.16). The leading cellular providers have started to deploy 4G technologies, with Verizon and AT&T launching 4G LTE networks and Sprint utilizing its new 4G WiMax network. In terms of mobile devices, many newer Android-based smartphones are 4G LTE capable, and both the iPhone 5 and the iPad 3 are expected to have built-in 4G LTE capabilities when released in the second half of 2012.

4G LTE refers to the evolved version of LTE that is being developed by 3GPP to meet or exceed the requirements of the International Telecommunication Union (ITU) for a true fourth generation radio-communication standard known as IMT-Advanced. 4G LTE, whose project name is LTE-Advanced, is being specified initially in Release 10 of the 3GPP standard, with a functional freeze targeted for March 2011. The 4G LTE standard will continue to be developed in subsequent releases. In October 2009, the 3GPP Partners formally submitted LTE-Advanced to the ITU as a candidate for 4G IMT-Advanced1. The certified technology specifications for IMT-Advanced are expected to be published in early 20112.

The certified technology specifications for IMT-Advanced are expected to be published in early 20112. Key ITU requirements for IMT-Advanced that 4G LTE will support include the following3: A high degree of common functionality worldwide while retaining the flexibility to support a wide range of local services and applications in a cost-efficient manner Compatibility of services within IMT and with fixed networks Capability for interworking with other radio systems High quality mobile services User equipment suitable for worldwide use User-friendly applications, services, and equipment Worldwide roaming capability Enhanced peak data rates to support advanced mobile services and applications (100 Mbps for high mobility and 1 Gbps for low mobility) 3GPP cites an additional reason to align 4G LTE with IMT-Advanced: IMT-conformant systems will be candidates for any new spectrum bands identified by the WRC-07 (World Radiocommunication Conference). 4

4G- * 4th generation of mobile communications * LTE- (Long Term Evolution) are 3GPP specifications for mobile broadband networks. 4G Technology is basically the extension in the 3G technology with more bandwidth and services offers in the 3G. Long Term Evolution (LTE) is a radio platform technology that will allow operators to achieve even higher peak throughputs than HSPA+ in higher spectrum bandwidth.

4G 4G, known as 4th generation of mobile communications, and LTE (Long Term Evolution) are 3GPP specifications for mobile broadband networks. ITU considers IMT-Advanced (International Mobile Telecommunication) technologies as true 4G standards. As per the official definition, IMT-Advanced should be able to deliver peak download speeds of 1Gbps in stationary environments, while 100Mbps in high mobile environments. Initially, ITU completed the assessment of 6 candidate’s wireless mobile broadband standards for official 4G standard. Finally, 2 technologies, LTE Advanced and WirelessMAN-Advanced are accorded the official designation of IMT-Advanced. Even though, LTE Advanced is considered as true 4G standard, ITU also allowed to use HSPA+,WiMax and LTE as 4th generation technologies. As per the IMT-Advanced specification peak spectral efficiency should be 15bps/Hz for downlink and 6.75bps/Hz for uplink. This spectral efficiency and other IMT-Advanced requirements are achieved by 3GPP Release 10 (LTE-Advanced). LTE LTE was initiated with the 3GPP Release 8 (Freeze in March 2008), and further evolved in 9 and 10 releases. High spectral efficiency is one of the key features of LTE which was achieved using Orthogonal Frequency Division Multiple Access (OFDMA) with 64-QAM (Quadrature Amplitude Modulation) technique. Use of MIMO (Multiple Input Multiple Output) antenna techniques is another key point which improved the spectral efficiency of LTE to 15bps/Hz. LTE should be able to support up to 300Mbps downlink and 75Mbps in uplink as per the 3GPP specification. Architecture of LTE is much simpler and flat when compared with the previous 3GPP releases. eNode-B directly connects with System Architecture Evolution Gateway (SAE-GW) for data transfer, while it connects with Mobile Management Entity (MME) for signaling as per the LTE architecture. This simple eUTRAN architecture allows better utilization of resources, which ultimately ends up with OPEX and CAPEX savings to the service provider

4G is short for Fourth (4th) Generation Technology. 4G Technology is basically the extension in the 3G technology with more bandwidth and services offers in the 3G. But at this time nobody exactly knows the true 4G definition.The expectation for the 4G technology is basically the high quality audio/video streaming over end to end Internet Protocol. Long Term Evolution (LTE) is a radio platform technology that will allow operators to achieve even higher peak throughputs than HSPA+ in higher spectrum bandwidth. Work on LTE began at 3GPP in 2004, with an official LTE work item started in 2006 and a completed 3GPP..

4g is the fastest network build till now bt launched in India In telecommunications, 4G is the fourth generation of cellular wireless standards. It is a successor to the 3G and 2G families of standards. In 2009, the ITU-R organization specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G standards, setting peak speed requirements for 4G service at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users).[1] A 4G system is expected to provide a comprehensive and secure all-IP based mobile broadband solution to laptop computer wireless modems, smartphones, and other mobile devices. Facilities such as ultra-broadband Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users. Pre-4G technologies such as mobile WiMAX and first-release Long term evolution (LTE) have been on the market since 2006[2] and 2009[3][4][5] respectively, and though often branded as 4G in marketing materials, the current versions of these technologies provide downstream peak bitrates of 144 Mbit/s and 100 Mbit/s respectively, and do consequently not fulfill the original ITU-R requirements of data rates approximately up to 1 Gbit/s for 4G systems.

4G, known as 4th generation of mobile communications, and LTE (Long Term Evolution) are 3GPP specifications for mobile broadband networks. Different eras of mobile communication are categorized into generations such as 1G, 2G, 3G, and 4G, where each generation has a number of technologies such as LTE. ITU (International Telecommunication Union) considers LTE-Advanced as the true 4G standard, while it also accepts LTE as a 4G standard.

it is better and faster than 3g.
Posted: 05-09-2011 @ 21:21:16
there is no such thing as real 4G in the US. they're just trying to confuse you with all the different acronyms. LTE is faster than 3G but is not 4G. They label it was 4G LTE just so the general public understands it's faster than 3G.
