Mobile Broad Band and the Multi-Network Path to 4G

This paper the field of wireless broadband multimedia communications is given following two lines: on one side evolution in Second and Third creation of mobile communications, on the additional face development of multimedia data road and rail network. These two evolutions will merge in to a new concept of communications: the Mobile Broadband Systems, or fourth creation (4G) of mobile multimedia communications The survey of mobile IT medium (in the year 2005-06) was separated into five categories of terminals, transport, service platform, applications as fine as functions to respond to social and environmental requirements. This paper presents an overall idea of the 4G features framework and combination of mobile communication .The features of 4G systems can be summarized with one word integration .The 4G systems are about impeccably integrating terminals networks and applications to convince the user needs. The 4G-infrastructure machinist will mix more than a few technologies, each of which has its optimal usage. The connections to one of them will result in a real time trade of, which will offer the user the best possible service. An approximate of 6 billion users at the end of 2006 justifies the study and research for the 4G systems.
