An overview of third-generation wireless personal communications is presented, and the challenges to meet its demands are examined.Abstract:
An overview of third-generation wireless personal communications is presented, and the challenges to meet its demands are examined. At the ITU level, the third generation is known as IMT-2000. In Europe, the third generation of wireless personal communications is known as UMTS. Special attention has been paid in giving a brief description of the research and development, standardization, and regulatory activities. The UMTS terrestrial radio access (UTRA) concept is presented. The different ACTS projects involved in making UMTS a success are introduced.read more
