UMTS, The Fundamentals

UMTS (Universal cellular Telecommunication process) is the 3rd iteration telecommunications approach in keeping with WCDMA. WCDMA (Wideband Code department a number of entry) is the radio interface for UMTS. WCDMA is characterized by means of use of a much wider band than CDMA. It has extra merits of excessive move price, and elevated approach skill and verbal exchange caliber by way of statistical multiplexing, and so forth.

The deployment of International Mobile Telecommunications-2000 (IMT-2000) networks has started in several countries, and high-speed multimedia services are currently being provided and further developed. However, even at this introductory stage of 3G systems, enhancement activities have already started on a global scale. In fact, for several years already there have been active discussions and exchange of visions about systems beyond IMT-2000, commonly referred to as the fourth generation, or 4G for short, in various forums and organizations as well as in the open literature.

Today the existing mobile subscriber base is huge, around one-quarter of the world’s population. Such an impressive figure speaks by itself in terms of potential for an explosive growth in traffic. Even though 4G is approached from a user-centric perspective, rapidly changing technology trends need to be taken into account when developing future scenarios. 4 Global revenues from mobile voice and data communications (only 3G). categories: (1) system-related technologies, (2) access network and radio interface, (3) utilization of spectrum, (4) mobile terminals, and (5) applications.

2 User Needs and Trends Users will expect new dynamic and flexible applications and services that are ubiquitous and available across a range of devices, possibly using a single subscription (or a single identity, number, or address) to access any network. Adaptable communication systems offering customized and ubiquitous services based on diverse individual needs will require flexibility in the technology in order to satisfy multiple demands simultaneously. To satisfy users, work has already begun on the convergence of telecommunication services such as digital broadcasting and commercial wireless services.
