Visualization Analysis on Key Technologies of Technical Evolution - In the Field of 3G Mobile Communication

Abstract:

Taking the patent literature in the field of the 3G mobile communication in Derwent Innovation Index (DII) as the research object, this paper utilizes CiteSpace and Σ index to conduct analysis on key technologies of technical evolution in the 3G mobile communication system. Then, the key technologies from 1994 to 2009 are separated into four periods. Next, interpretations are formulated to study these key technologies represented by Derwent manual codes. Finally, this paper illustrates the key technologies and their main evolutional paths in different periods.
