LTE Advanced is a mobile communication standard. It is currently being standardized by the 3rd Generation Partnership Project (3GPP) as a major enhancement of 3GPP Long Term Evolution. LTE (Long Term Evolution) standardization has come to a mature state by now where changes in the specification are limited to corrections and bug fixes.

LTE mobile communication systems are expected to be deployed from 2010 onwards as a natural evolution of Global system for mobile communications (GSM) and Universal Mobile Telecommunications System (UMTS). Being defined as 3G technology LTE does not meet the requirements for 4G also called IMT Advanced as defined by the International Telecommunication Union such as peak data rates up to 1 Gbit/s. The ITU has invited the submission of candidate Radio Interface Technologies (RITs) following their requirements as mentioned in a circular letter.

The mobile communication industry and standardization organizations have therefore started to work on 4G access technologies such as LTE Advanced. At a workshop in April 2008 in China 3GPP agreed the plans for future work on Long Term Evolution (LTE) A first set of 3GPP requirements on LTE Advanced has been approved in June 2008. Besides the peak data rate 1 Gbit/s that fully supports the 4G requirements as defined by the ITU-R, it also targets faster switching between power states and improved performance at the cell edge.

Detailed proposals are being studied within the working groups.
