    The design and development of UMTS will be influenced, to some degree, by the outcome and conclusions generated by the RACE II CODIT project. The paper points out the spectrum requirements of the CODIT system concept and then compares those requirements with the spectrum identified for UMTS. The paper then discusses whether high bit rate data services require new spectrum and whether this leads to... View full abstract»

    Mobility and personal communications is Area 4 of seven principal areas of research identified in the ACTS Programme under the European 4th Framework umbrella. The budget allocated for Area 4 substantially exceeds that available previously in RACE I and II, but preparation of the workplan for this element of ACTS exposed significant differences of view among contributors to the “Task” ...

  • Co-channel interference suppression for TDMA mobile radio systems

    Publication Year: 1994, Page(s):9/1 - 9/6

    A technique is described that enables a signal to be detected in the presence of high levels of like-modulated co-channel interference. In land mobile radio systems the extent to which a receiver can tolerate co-channel interference is one factor limiting the traffic carrying capacity of a network. Consequently any technique that enables the receiver to operate at lower signal to interference rati... View full abstract»

  • Cash on delivery-mobile consumer management goes back to basics

    Publication Year: 1994, Page(s):6/1 - 6/6

    Personal mobile services are becoming ever more sophisticated but the mechanisms of obtaining payment for those services are still built around customer accounts and consumer credit, two concepts that bring their own issues of risk and management overhead. Given sufficient bandwidth, imagination and entrepreneurism it is not difficult to envisage a future of mobile consumers accessing information,... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (348 KB)

    The Universal Mobile Telecommunications System (UMTS), is an European standards development within the framework of the ITU's Future Public Land Mobile Telephone System (FLMTS) initiative, now known as IMT-2000 (International Mobile Telecommunications at 2000 MHz). It is intended to support a wide range of services, with terminal mobility being a prime requirement. However, UMTS must not only be f... View full abstract»

    The seeds of Third Generation Mobile Systems (TGMS) as represented by the Universal Mobile Telecommunication System (UMTS) and Future Public Land Mobile Telecommunication Systems (FPLMTS) were sown in 1986 with the parallel activities of Project R2029 of the European RACE Definition Phase in the first Framework Programme and the establishment of the global Interim Working Party 8/13 (IWP 8/13) on ...

    The use of adaptive antennas in mobile communications base stations is discussed. They offer the potential of increased spectrum efficiency, extended range coverage and higher rate of frequency reuse. To further advance the use of adaptive antennas in mobile communications, an EC RACE project (R2108), code named TSUNAMI has been set-up. The paper presents an overview on this project together with ... View full abstract»

  • The U.K. LINK personal communications programme: downlink design for a DS-CDMA field trial system

    Publication Year: 1994, Page(s):7/1 - 7/6
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (380 KB)

    DS-CDMA is a candidate air interface for the next generation of mobile radio systems and as such has been the focus of a great deal of attention. There are many contentious issues relating to its performance and implementation and the worldwide debate continues over which access technique is the most suitable to take mobile radio into the 21st Century. In the paper, a DS-CDMA field trial system is... View full abstract»

  • Review of European activities concerned with defining the satellite component of UMTS

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (280 KB)

    The Universal Mobile Telecommunications System (UMTS) will predominantly be a terrestrial mobile system, however, it is envisaged that a satellite component will also be required. Bearing this in mind, two major European projects, COST 227 and SAINT, are currently in the process of defining a satellite component of UMTS. This paper summarises the key results of both projects, comparing and contras... View full abstract»

  • The migration towards UMTS

    Publication Year: 1994, Page(s):2/1 - 2/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (184 KB)

    The work programme of ETSI currently shows UMTS start of service around 2000 with all conformance specifications complete by late 1998. These short timescales require manufacturers, operators and regulators to be clear on the ways in which the system can be deployed as a commercially viable business. To understand the factors that will affect the commercial deployment of UMTS, it is of benefit to ... View full abstract»

  • Adaptive antennas for frequency re-use in every cell of a GSM network

    Publication Year: 1994, Page(s):11/1 - 11/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (384 KB)

    The capacity of cellular radio networks can be considerably increased if carriers are reused in every cell. The paper shows how a well-known technique (an adaptive antenna) can, together with other techniques, be used to combat the resulting co-channel interference to make this possible. Adaptive antennas have been employed in military systems for many years as a countermeasure for deliberate, hig... View full abstract»
