4G” is the term used to refer to the forthcoming "Fourth Generation" of mobile wireless services that is currently being defined by the International Telecommunication Union (ITU). Its Radiocommunication Sector (ITU-R) is in the process of establishing an agreed and globally accepted definition of 4G wireless systems using the name IMT-Advanced. Current 3G systems were established through ITU’s previous project on International Mobile Telecommunications 2000 (IMT-2000).
As background for this project, ITU published a document, “Recommendation ITU-R M.1645: Framework and overall objectives of the future development of IMT-2000 and systems beyond IMT-2000.”
The IMT-Advanced project schedule shows the requirements and evaluation criteria published in 2008 with submissions to occur through 2009. In Release 10, 3GPP will address the IMT-Advanced requirements in a version of LTE, called LTE-Advanced, for which specifications could become available in 2011. WiMAX will address the IMT-Advanced requirements in a version called Mobile WiMAX 2.0, to be specified in IEEE 802.16m. Such a 4G family, in adherence to the principles defined for acceptance into this ITU process, is globally recognized to be one that can grow to include all aspects of a marketplace arriving beyond 2010, thus complementing and building upon an expanding and maturing 3G business
