Long Term Evolution (LTE) is a 4G wireless broadband technology developed by the Third Generation Partnership Project (3GPP), an industry trade group. 3GPP engineers named the technology "Long-Term Evolution" because it represents the next step (4G) in a progression From GSM, a standard 2G, to UMTS, 3G technologies based on GSM. LTE provides significantly higher peak data rates with a potential of 100 Mbps downstream and 30 Mbps upstream, reduced latency, scalable bandwidth capacity and compatibility with existing GSM and UMTS technology. Future developments could yield a maximum throughput of the order of 300 Mbps.
The upper layers of LTE are based on TCP / IP, which will probably result in a total IP network similar to the current state of the cable communications. LTE will support mixed data, voice, video and messaging traffic. LTE uses OFDM (Orthogonal Frequency Division Multiplexing) and, in later versions, a Multiple Input Multiple Output (MIMO) antenna technology similar to that used in the IEEE 802.11n Wireless Local Area Network (WLAN) standard. The higher signal-to-noise ratio (SNR) in the MIMO-enabled receiver, together with OFDM, provides better coverage and performance, especially in dense urban areas.
LTE is scheduled to be commercially released in 2010 by Verizon Wireless and AT & T Wireless. T-Mobile and Alltel have also announced plans to build 4G capabilities based on LTE. These networks will compete with Clearwire WiMAX for both corporate and consumer broadband wireless customers. Outside the US telecommunications market, GSM is the dominant mobile standard, with more than 80% of the world's cell phone users. As a result, HSDPA and then LTE are the likely wireless broadband technologies of choice for most users. Nortel and other infrastructure providers are focusing significant research and development efforts on building LTE base stations to meet expected demand. When deployed, LTE has the potential to bring ubiquitous computing to a global audience, with a wire experience for mobile users around the world.

LTE is a 4G wireless communications standard developed by the 3rd Generation Partnership Project (3GPP) designed to provide up to 10 times the speed of 3G networks for mobile devices such as smartphones, tablets, netbooks, notebooks and wireless hotspots. 4G technologies are designed to provide IP-based voice, data and multimedia transmission at speeds of at least 100 Mbit per second and up to 1 GBit per second.
4G LTE is one of several 4G standards competing along with Ultra Mobile Broadband (UMB) and WiMax (IEEE 802.16). Leading cellular providers have begun implementing 4G technologies, with Verizon and AT & T launching 4G LTE and Sprint networks using their new WiMax 4G network. As for mobile devices, many new Android-based smartphones are compatible with 4G LTE and both the iPhone 5 and iPad 3 are expected to have integrated LTE 4G capabilities when they are released in the second half of 2012.
