		UMTS has the support of many major telecommunications operators and manufacturers because it represents a unique opportunity to create a mass market for highly personalised and user friendly mobile access to the Information Society.
		UMTS seeks to build on and extend the capability of today’s mobile, cordless and satellite technologies by providing increased capacity, data capability and a far greater range of services using an innovative radio access scheme and an enhanced, evolving core network.
		For the commercial and technical success of UMTS, and to meet its 2002 launch deadline, a number of steps are being undertaken by manufacturers, standards bodies, operators and regulators around the world:

		UMTS is the dominant 3G solution being developed, representing an evolution from the GSM network standards, interoperating with a GSM core network.
		UMTS will use a wideband CDMA technology for transmission, and a more efficient modulation than GSM.
		UMTS also implements an ATM infrastructure for the wireline interface, using both AAL2 and AAL5 adaptations; AAL2 for real-time traffic and AAL5 for data and signaling.

	UMTS: Universal Mobile Telecommunications Systems
		UMTS terminals will exist in a world of multiple standards that will enable operators to offer maximum capacity and coverage to their user base by combining UTRA with second- or third-generation standards.
		UMTS is also being designed to offer data rate on demand, where the network reacts flexibly to a user’s demands based upon his or her profile and the current status of the network.
		UMTS must be capable of co-existing and working with existing second-generation mobile communications technologies so that operators can choose to reuse their existing infrastructure assets and expertise.

	What is UMTS? - a definition from Whatis.com - see also: Universal Mobile Telecommunications Service
		UMTS offers a consistent set of services to mobile computer and phone users, no matter where they are located in the world.
		Once UMTS is fully available, computer and phone users can be constantly attached to the Internet wherever they travel and, as they roam, will have the same set of capabilities.
		UMTS may allow the Virtual Home Environment (VHE) to fully develop, where a roaming user can have the same services to either at home, in the office or in the field through a combination of transparent terrestrial and satellite connections.

	UMTS Communication FINAL E (Site not responding. Last check: )
		The UMTS Forum suggested that existing operators should not be excluded from bidding for UMTS licenses, because of the huge investment costs required for UMTS, whilst a number of GSM operators staked a claim to the automatic grant of UMTS licences, in order to allow users to benefit from their skills and experience.
		UMTS is viewed as a crucial test to Europe's competitiveness, both for the mobile communications industry and because of the importance of mobile communications for economic players at large.
		The Commission supports the UMTS standardisation efforts undertaken so far by ETSI, calls for all interested parties to contribute to this process and welcomes the fact that standards development is being led by the private sector and that a consensus seems to be developing on the issue of the core network.

	UMTS FAQ
		UMTS was developed mainly for countries with GSM networks, because these countries have agreed to free new frequency ranges for UMTS networks.
		UMTS Forum represents the opinions and views of the telecommunication industry and operators and GSM Associates is a mobile operator organisation.
		UMTS specifications do not have any special interface planned for other mobile networks, but all telephone networks can be connected to UMTS core network with standard S7 (or other) signalling system using E1s or T1s.

	UMTS
		UMTS itself is a standard developed initially for European markets in mind but is rapidly becoming a globally adopted standard (amongst others).
		Having said this, building a UMTS network is still an expensive option, and there are also a number of technologies which aim to extend existing 2G infrastructure and in the process reduce the overall cost of implementing a service that will provide data transfer rates that are competitive with the full standards.
		UMTS basically uses the same idea (this occurred mainly for the sake for backwards compatibility) except that it adds extended functionality.

	World Wide Words: UMTS
		UMTS is being developed by a consortium that includes Sony, Alcatel, Motorola, Italtel, Bosch, Nortel and Siemens.
		By 2005, the Department of Trade and Industry hopes, UMTS will be fully operational, enabling consumers to have a single handset that could act as both a home and mobile telephone with a single number, multimedia capabilities and world roaming.
		UMTS could take the penetration of mobile phones up to as much as 60 per cent of the UK population, compared with around 15 per cent now, according to ABN Amro.

	Integration of UMTS and B-ISDN - is it possible or desirable?
		UMTS is envisaged as providing the infrastructure needed to support a wide range of multimedia digital services, or teleservices [CHEU94], requiring channel bit-rates of less than the UMTS upper ceiling of 2 Mbits/second, as allocated to it in the World Administrative Radio Conference (WARC) '92 bands.
		Interoperability between UMTS and ISDN in some fashion will be necessary to support the interoperability between the fixed and mobile networks that users have already come to expect with existing mobile networks, and to meet the expectation of consistency of fixed/mobile service provision laid out in the initial RACE vision.
		For example, a UMTS handover can be handled as a multi-party call, where the cell the mobile is moving to is added to the call as a new party, and the old cell is dropped as a party leaving the call, using ADD(_party) and DROP (_party) primitives.

	UMTS TDD Alliance :: Technology
		UMTS TDD Solutions have been shown to support peak downlink sector capacities of up to 12Mbps and average capacities per sector that are more than 3 times higher than any other commercial mobile platform.
		UMTS TDD is one of 3 alternative air-interface (physical layer) standards of UMTS, which all share higher layer protocol stack and core network / back office architecture.
		The UMTS TDD standard is inherently designed to support N=1 reuse (a single frequency network) in response to network operators in the IMT 2000 3G band, which are only allocated a single TDD channel.

	UMTS-WLAN
		UMTS has been endorsed by major standards bodies and manufacturers and was the planned standard for mobile users around the world by 2002, but has been delayed doe to various problems (EU 2002).
		UMTS is conceived as a multi-function, multi-service, multi-application digital mobile system that will provide personal communications at rates ranging from 144 kbps up to 2 Mbps according to the specific environment, will support universal roaming, and will provide for broadband multimedia services.
		Both in the case of UMTS and WLAN there are a number of actors or players that are involved in the development and deployment activities, including network operators, equipment vendors, third party service providers and end-users along with policy-makers at other stakeholder nationally and internationally.

	3g-generation: What is 3G ?
		UMTS (Universal Mobile Telecommunications System) is a so-called "third-generation (3G)," broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to and possibly higher than 2 megabits per second (Mbps), offering a consistent set of services to mobile computer and phone users no matter where they are located in the world.
		Once UMTS is fully implemented, computer and phone users can be constantly attached to the Internet as they travel and, as they roaming service, have the same set of capabilities no matter where they travel to.
		UMTS promises to realize the Virtual Home Environment in which a roaming user can have the same services to which the user is accustomed when at home or in the office, through a combination of transparent terrestrial and satellite connections.
