Long Term Evolution

3GPP Long Term Evolution, or simply LTE, is a high-speed wireless data packet communication standard for mobile phones that is a further evolution of HSDPA. Together with HSPA+, an evolved standard of HSDPA, it is called a 3.9G wireless communication standard.
It is based on Release 8, a wireless high-speed data packet access standard finalized in December 2008 by 3GPP (3rd Generation Partnership Project), the standards body for 3G asynchronous mobile communication technology. Using its core technologies OFDM and MIMO, it can communicate more than 12 times faster than HSDPA. The maximum download speed is 173Mbps (based on 2x2 MIMO).
LTE is a step toward 4th-generation wireless technology (4G), designed to increase the capacity and speed of mobile phone networks. Where the current generation of mobile communication is generally known as 3G (3rd generation), LTE is marketed as 4G. Compared with the specifications set by the standards body, LTE is 3.9G because it does not fully satisfy the IMT-Advanced 4G requirements. Verizon Wireless and AT&T Mobility in the US, along with several global carriers, announced plans to switch their networks to LTE starting in 2009.
In South Korea in particular, as of September 2013 all three carriers, KT, SK Telecom, and LG U+, provide LTE service nationwide.
The first commercial service was launched by the operator TeliaSonera in Stockholm, Sweden and Oslo, Norway on December 14, 2009.

In South Korea in particular, as of March 2012 LG U+ alone provides service covering every region of the country with the world's first complete nationwide LTE network, and as of July 2012 South Korea's SK Telecom also provides LTE service over a complete nationwide network. KT provides service with coverage of 84 cities and is building coverage for all regions of the country.
LTE Advanced
LTE Advanced is a full-fledged 4th-generation mobile communication system that succeeds Long Term Evolution (LTE), a 3.9G mobile communication technology. It is defined with a maximum stationary transmission speed of 1 Gbps downlink and 500 Mbps uplink. As yet (May 2013), no carrier has commercialized LTE Advanced. KT announced commercialization around July 2013 and SKT around September. Existing LTE devices and LTE Advanced are not compatible.
