	UMTS: Universal Mobile Telecommunications Systems
		Current wireless or mobile systems, despite their evolution, are still constrained in terms of the data rate they can offer and their flexibility to manipulate complex, yet user-friendly multimedia services.
		The system seeks to build on and extend the capability of today’s mobile, cordless, and satellite technologies by providing increased capacity and data capability as well as a far greater range of services using an innovative radio access scheme and an enhanced, evolving core network (Struthers, 1998).
		The system will be a member of a new family of mobile telecommunications systems being developed by the ITU for deployment across the world.

	Evolution of Mobile Telecommunications Toward U
		In Europe, the European Telecommunications Standards Institute (ETSI) is looking for the definition of a Universal Mobile Telecommunications System (UMTS); parallel standardization activities on a worldwide level are undertaken within the International Telecommunications Union (ITU) under the banner of Future Public Land Mobile Telecommunication System (FPLMTS)/International Mobile Telecommunications in the Year 2000 (IMT-2000).
		This means that the evolution of existing (mobile) communications systems toward UMTS requires the early integration of IN and B-ISDN principles as well as the evolution of the current radio interfaces toward the target UMTS radio interface.
		The previous section indicated that the evolution from any existing telecommunications system toward UMTS requires a big investment and that only a partial set of the target UMTS capabilities could be provided in the short to medium term.

	UMTS Technical Details
		UMTS is above 2G mobile systems for its potential to support 2Mbit/s data rates from the outset.
		UMTS is conceived as a global system, comprising both terrestrial and satellite components.
		In practical implementations, UMTS terminals might be unable to operate at the highest data rates at all times, and in remote or heavily congested areas system services might only support lower rates due to radio propagation constraints or economic reasons.

	IEC
		The first systems offering mobile telephone service (car phone) were introduced in the late 1940s in the United States and in the early 1950s in Europe.
		The introduction of cellular systems in the late 1970s and early 1980s represented a quantum leap in mobile communication (especially in capacity and mobility).
		As previously mentioned, IMT stands for International Mobile Telecommunications, and “2000” represents both the scheduled year for initial trial systems and the frequency range of 2000 MHz (WARC’92: 1885—2025 MHz and 2110—2200 MHz).
