Abstract:
The third generation mobile communication system, UMTS has recently been developed by ETSI with the target to provide a wide bandwidth mobile service capable of transmitting speech or data at rates upto 2.048 Mbit/s, utilizing spread spectrum technology COMA. UMTS is one of the premier's 3G technologies that is gaining promrnence and is predicted to dominate the global market. In this thesis report, the critical issue has been taken to provide scenarios and analysis within the UMTS Radio Access Network (UTRAN) and Core Network (CN) based on ATM backbone, along with the insight interoperability between UMTS networks and Internet Protocol (IP) based external service networks. The thesis report covers the steps for introducing the UMTS technology. IT ALSO identifies the technologies, which will likely be required for UMTS continuing evolution to create a single, seamless mass medium that will combine the reach, quality and emotion of information with the needs of the network user. Increased agility for multimedia services including those offered on the Internet and other third party sources is what people are looking for. The challenge is deriving multiple data streams, at extremely high transfer rates, accessible any where through out the world irrespective of the point of home subscription. Adequate access to the spectrum is a key requirement for the development and enhancement of the Universal Mobile Telecommunication System, UMTS. This thesis report focuses on the spectrum for a global UMTS/ IMT -2000 systems in order to estimate the future terrestrial spectrum requirement in next years. A number of different environments have been taken into a generic traffic model, which can be seen as being usable for many countries in the world including Pakistan with varying the demographical data. The thesis report is aimed at being of interest to all concerned would-wide. especially in Pakistan, involved in.the future development of the Mobile telecommunication industry.
