What is 4G LTE?

It stands for Long Term Evolution, commonly called as 4G LTE. It is a wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies. It has increase the capacity and speed using a different radio interface together with core network improvements.

4G LTE is has speed up to 10x faster than 3G.2, that gives you clear, crisp video streaming and it's faster than ever before. You can also download music, apps, and games in an instant.

4G LTE was first introduced in public by TeliaSonera in Stockholm and Oslo on December 14, 2009.

Carriers are now upgrading their networks to LTE with both GSM/UMTS networks and CDMA2000 networks like Verizon Wireless. Verizon Wireless launched the first large-scale LTE network in North America in 2010, and au by KDDI in Japan have announced they will migrate to LTE.
In India Airtel offered the LTE services in April 2012. LTE is believe to become the first truly global mobile phone standard, although the different LTE frequencies and bands used in different countries will mean that only multi-band phones will be able to use LTE in all countries where it is supported.

Companies market LTE as 4G wireless service, LTE (as documented in the 3GPP Release 8 and 9 document series) does not satisfy the technical requirements the 3GPP consortium has adopted for its new standard generation, and which were originally set forth by the ITU-R organization in its IMT-Advanced specification. However, due to marketing pressures and the significant advancements that WIMAX, HSPA+ and LTE bring to the original 3G technologies, ITU later decided that LTE together with the aforementioned technologies can be called 4G technologies. The LTE Advanced standard formally satisfies the ITU-R requirements to be considered IMT-Advanced.And to differentiate LTE Advanced and WiMAX-Advanced from current 4G technologies, ITU has defined them as "True 4G".
