    Multi-standard software definable radios (SDR) which are capable of operation according to a variety of different mobile radio standards represent an extremely powerful tool for evolution towards future third-generation cellular systems. An approach based on the use of a fixed-bandwidth analogue front-end for the implementation of a wideband digital SDR receiver was introduced by Karimi and Friedr... View full abstract»

    The development of dual-band dual-mode D-AMPS/AMPS mobile handsets and radio stations has added pressure on GSM service providers to follow similar technology breakthroughs as a first step towards UMTS/FPLMTS. A frequency agile device accommodating both GSM standard frequency bands would serve more than 25 million GSM subscribers, with expectations as high as 100 millions subscribers by the year 2...

    The evolution of handset technology is likely to present a range of multi-mode terminals in the future which, in turn, can support a range of services. However, at the current time few options for cordless/cellular handsets and services are available. The GSM/DECT has been the dominant multi-mode terminal technology to date. This paper highlighted the economic factors against GSM/DECT and those in... View full abstract»

    As mobile communications grow rapidly new frequency bands are being used. At the same time the mobile service providers are trying to equip end users with new terminals which bring additional benefits from operating at more than one frequency band. First commercial hand held portable terminals that can operate at two bands have also appeared on the market. Nevertheless the design of dual band hand... View full abstract»

    Software radio has been recognised as the next major leap forward in mobile communications, particularly in the light of the many existing worldwide air interface standards and wide range of future proposals for UMTS. The European Commission has recognised that fact and a major international project has been underway to explore the many issues involved in making a practical terminal. The ACTS FIRS...

    Multi-standard software-definable radios which are capable of operation according to a variety of different mobile radio standards represent an extremely powerful tool for evolution towards future third-generation cellular systems. This is particularly the case in Europe where the emergence of advanced UMTS air-interfaces needs to be accompanied with some degree of backward compatibility with the ... View full abstract»
