摘要：The use of Information and Communication Technology (ICT) services, such as mobile phones and the Internet, continues to grow worldwide and Trends show explosive bandwidth growth of the Internet at large and for mobile broadband networks in particular. This is, consequently, driving the need for continued innovations in wireless data technologies to provide more capacity and higher quality of service. The International Telecommunications Union (ITU) has coined the term International Mobile Telecommunications-Advanced (IMT-Advanced) to identify mobile systems whose capabilities go beyond those of IMT-2000. Some of the key features of IMT-Advanced will be; Worldwide functionality & roaming, Compatibility of services, Interworking with other radio access systems and Enhanced peak data rates to support advanced services and applications (100 Mbit/s for high and 1 Gbit/s for low mobility). The IMT-Advanced systems will support low to high mobility applications and wide range of data rates, in accordance with service demands in multiuser environment. This paper provides a brief insight in to the IMT-Advanced standards and its key requirements which will be a pathway to next generation of wireless communication or 4G and te
