An Overview on the Universal Mobile Telecommunications Systems

Abstract

In this paper it is presented the main types of Universal Mobile Telecommunications Systems (UMTS) technologies with their evolution over time. Also the main characteristics of UMTS technology are analyzed, including the new features for each of them. A statistical study on the interest in the academic world by publishing scientific articles in the field is shown at the end of this paper as well. This analysis was done based on two types of database: (1) indexed database - Science Direct; (2) the database of open access - Google Scholar. If Google Scholar Academic results represent the scientific material of any scientific quality level related to UMTS technology, the analysis of the Science Direct database gives a clear picture of high- level scientific publications and highly topical.
