In the feasibility study for LTE Advanced, 3GPP determined that LTE Advanced would meet the ITU-R requirements for 4G. LTE Advanced should be compatible with first release LTE equipment, and should share frequency bands with first release LTE. The target of 3GPP LTE Advanced is to reach and surpass the ITU requirements. 3 First technology demonstrations and field trials.2 Timeframe and introduction of additional features.Such networks are often described as ‘Gigabit LTE networks’ mirroring a term that is also used in the fixed broadband industry. Three technologies from the LTE-Advanced tool-kit – carrier aggregation, 4x4 MIMO and 256QAM modulation in the downlink – if used together and with sufficient aggregated bandwidth, can deliver maximum peak downlink speeds approaching, or even exceeding, 1 Gbit/s. Detailed proposals are being studied within the working groups. Besides the peak data rate 1 Gb/s as defined by the ITU-R, it also targets faster switching between power states and improved performance at the cell edge. A first set of specifications were approved in June 2008. At a workshop in April 2008 in China, 3GPP agreed the plans for work on Long Term Evolution (LTE). The mobile communication industry and standards organizations have therefore started work on 4G access technologies, such as LTE Advanced.

Most vendors now support conversion of 'pre-4G', pre-advanced versions and some support software upgrades of base station equipment from 3G. WiMAX 2 is designed to be backward compatible with WiMAX 1 devices. Likewise, ' WiMAX 2', 802.16m, has been approved by ITU as the IMT Advanced family. Also, specifications must recognize those parts of the world in which wideband channels are not available. Consideration of recent World Radiocommunication Conference (WRC-07) decisions regarding frequency bands to ensure that LTE-Advanced accommodates the geographically available spectrum for channels above 20 MHz.Any exceptions will be considered by 3GPP. An LTE terminal should be able to work in an LTE-Advanced network and vice versa. Backward compatibility of LTE-Advanced with LTE.Scenarios and performance requirements for working with legacy radio technologies.Continual improvement to the LTE radio technology and architecture.Major technical considerations include the following: The ITU has invited the submission of candidate Radio Interface Technologies (RITs) following their requirements in a circular letter, 3GPP Technical Report (TR) 36.913, 'Requirements for Further Advancements for E-UTRA (LTE-Advanced).' These are based on ITU's requirements for 4G and on operators’ own requirements for advanced LTE. Being described as a 3.9G (beyond 3G but pre-4G), the first release of LTE did 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 Gb/s. The work by 3GPP to define a 4G candidate radio interface technology started in Release 9 with the study phase for LTE-Advanced. More LTE networks were deployed globally during 2010 as a natural evolution of several 2G and 3G systems, including Global system for mobile communications (GSM) and Universal Mobile Telecommunications System (UMTS) in the 3GPP family as well as CDMA2000 in the 3GPP2 family. The first commercial services were launched in Sweden and Norway in December 2009 followed by the United States and Japan in 2010. LTE standardization has matured to a state where changes in the specification are limited to corrections and bug fixes. The LTE+ format was first proposed by NTT DoCoMo of Japan and has been adopted as the international standard. Cellular network standards and generation timeline.
