In the following part we discuss why the next, large step of development was needed in the middle of the first decade after the millenium, at a time when the 3rd generation (UMTS, and its optimizations like HSPA) had not yet taken on full speed, and the bulk of mobile communication was still voice. We state the the driving factors and requirements formulated for an evolution, and list the limitations encountered with the legacy systems. In order to provide the reader with the baseline of the evolution we present condensed views of the main tracks in standardization of mobile and fixed networks. The chapter is concluded with snapshots on standardization history and operator commitments for future deployment of the Evolved 3GPP system.
