	Universal Mobile Telecommunications System - Wikipedia, the free encyclopedia
		Universal Mobile Telecommunications System (UMTS) is one of the third-generation (3G) mobile phone technologies.
		Precursors to 3G are 2G mobile telephony systems, such as GSM, CDMA, PDC, PHS and other 2G technologies deployed in different countries.
		Marketing material for UMTS has emphasised the possibility of mobile videoconferencing, although experience in Japan and elsewhere has shown that user demand for Video calls is not very high.

		Universal Mobile Telecommunications System (UMTS) is a European 3rd generation mobile phone system.
		UMTS and other similar 3rd generation systems are targeted to be compliant to IMT-2000 family, where the same terminal equipment could be used around the world with the second generation systems.
		The frequency bands allocated to the 3rd generation systems are 1885–2025 MHz and 2110–2200 MHz.

		Mobile telecoms Universal Mobile Telephone System: the technology standard to be used in third generation (3G) mobile phones (as expected to roll-out in Japan in late 2000, Europe in 2001 and the US in 2002), and which will permit a very high speed (384Kbs) data connection to the Internet.
		Universal Mobile Telecommunications System. A technology considered to be the next generation of GSM. It allows for wireless data transmissions to mobile units -- usually for Internet applications. Faster than GPRS, it supports transfer rates up to 2 Mbps. See also GSM and GPRS.

		In systems using the code division multiple access (CDMA) method, in a downlink from a radio network subsystem to user equipment, different users use the same code tree in which the spreading codes used in the system are arranged mutually orthogonally.
		In present mobile telephone systems, the data transmission rates used for both speech and data have been relatively low, and it has been possible to keep the resource problem under control.
		In new mobile telephone systems, the data transmission rates used will be considerably higher than in the present systems due to the wireless remote use of various computer applications.

		Universal Mobile Telephone System or UMTS is one of the third generation (3G) mobile phone technologies.
		However, this is still much greater than the 9600 bps of a single GSM error-corrected data channel, and offers the first prospect of practical inexpensive access to the World Wide Web on a mobile device.
		There exists other proposals for the ITU-IMT2000 requirements for 3G systems besides UMTS like: CDMA2000 proposed under the American IS standards including 1xEVDO (up to 2 MBps data only), 1xEVDV (greater than 2 MBps with voice support)and other proprietary systems including iBurst from Arraycom, Flarion and wCDMA-TDD (IPWireless).

	ABSTRACT
		A mobile, radio communication system is composed of fixed base-stations[1][4] and mobile handsets or terminals.
		It was preceded by the first generation NMT mobile telephone network, and the second generation of GSM.
		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.

		This spectrum efficient method contrasts sharply with earlier mobile systems that used a high powered, centrally located transmitter, to communicate with high powered car mounted mobiles on a small number of frequenices, channels which were then monopolized and not re-used over a wide area.
		IMTS or the Improved Mobile Telephone System equipment (and its variants) may still be around in certain countries, not the United States, serving isolated and rural areas not well covered by cellular.
		Time division systems are now being regarded as legacy technologies, older methods that must be accommodated in the short term future, but ones which are not the future itself.

	United States Patent Application: 0040198365
		When the mobile terminal user transitions from the first access node to the second access node, the user receives service in accordance with a secondary PDP context activated by the mobile terminal user.
		Indeed, even the proposed "Universal Mobile Telecommunications System 3GPP" standard for advanced packet radio service through wireless telephony networks, as is well known in the art, will not afford a QoS level as high as present-day wireless LAN networks.
		In practice, the mobile terminal user 16 will initially establish the secondary PDP context in the same manner in which the primary PDP context is established as described with respect to FIG.

		Today GSM is the largest system for mobile communications in the world, and exist on all continents.
		Within the next ten years, the UMTS (Universal Mobile Telephone System) is expected to become the dominant mobile system all over the world.
		Since GSM is the worlds largest system for mobile communication today and also lay the foundation for the future UMTS, it is important to recognize the need to study the methods and tools for forensic analysis of the GSM system.

	Equalisation Schemes for Digital Mobile Communications (Site not responding. Last check: 2007-10-18)
		Many radio channels, and especially the mobile communication channel, are subject to dispersion due to multipath propagation.
		Further, advanced digital cellular systems use coded modulation techniques to increase capacity and reliability, but the performance of these may be severely affected by the multipath channel.
		The work has concentrated on the mobile radio channel, and has developed a simulation model of the channel based on that recommended by COST 207 for use in the specifications of the digital mobile radio system GSM.

		Mobile communication technology has evolved along a logical path, from simple first-generation analogue products designed for business use to second generation digital wireless telecommunication system for residential and business environments.
		In addition to the capacity bottleneck, the utility of first-generation analogue systems was diminished by the proliferation of incompatible standards in Europe.
		The development of PCS is a global movement, which evolves from the existing second-generation mobile networks to allow new services to be established as well as to facilitate the steady improvement of the existing networks.

		The big difference with cellular telephones is the wide range of the low powered cell phones (transmission & reception) and certain telephone protocols that eliminate the need to say "over" and "out".
