  • The Year of Globalisation for Cdmaone™ by Perry Laforge, Executive Director, COMA Development Group, USA
    The Year of Globalisation for cdmaOne™ by Perry LaForge, Executive Director, COMA Development Group, USA Abstract The adoption rate, of cdmaOne™ has been the fastest of any wireless technology to date. It is already used in more than 30 countries around the world, serving over 7.8 million customers on five continents. The prediction is that by the year 2000 there will be about 60 million Wireless Local Loop (WLL) subscribers around the world, which represents 15% of the global mobile market, and growing to 200 million subscribers by 2005. Here, Mr. Perry LaForge of the COMA Development Group explains why he believes 1998 is the year of globalisation for the technology. The adoption rate of cdmaOne has been the fastest of any technology to date, and its adoption by major high growth wireless markets around the globe will continue to fuel subscriber growth and improve worldwide economies of scale. CDMA in Europe The unique, inherent advantages of cdmaOne, such as superior voice quality, longer battery life, and unexcelled call capacity have prompted enthusiasm for the technology even in Europe, where competing standards have historically dominated the marketplace. Nowhere is this demonstrated more clearly than the preliminary results of a field trial conducted in the UK by Vodafone Ltd. and QUALCOMM, Inc. The trial successfully displayed the technical feasibility of cdmaOne-Global System for Mobile Communications (GSM) integration, while maintaining cdmaOne over-the-air performance. Elsewhere in Europe, cdmaOne fixed wireless networks are being adopted in Poland, Ukraine and Russia. Customer Satisfaction In North America, where the competition from other digital technologies is most intense, cdmaOne has emerged as the dominant wireless standard.

  • Long Term Evolution (LTE) & Ultra-Mobile Broadband (UMB)
    Long Term Evolution (LTE) & Ultra-Mobile Broadband (UMB) Technologies for Broadband Wireless Access Subharthi Paul [email protected] (A survey paper written under guidance of Prof. Raj Jain) Download Abstract The evolution of wireless telephone technologies can be discretely grouped into various generations based on the level of maturity of the underlying technology. The classification into generations is not standardized on any given metrics or parameters and as such does not represent a strict demarcation. However, it represents a perspective which is commonly agreed upon, both by industry and academia, and hence conceived to be an unwritten standard. At this time, there are two major efforts towards the development of the next generation - "4G" wireless access technology. The 3GPP or 3rd Generation Partnership project (brand named as Long Term Evolution) is the name of the 4G efforts being undertaken in Europe and the 3GPP2 or 3rd Generation Partnership project 2 (brand named as Ultra Mobile Broadband) is the 4G effort of North America and parts of Asia. This survey tries to present an evolutionary and objective sketch to the development efforts of these technologies that mark the future of wide area broadband wireless access technologies.

    The GSMA spectrum primer series The spectrum policy dictionary 1 2 The spectrum policy dictionary These handbooks provide a general introduction to mobile spectrum, how it is managed and the challenge posed by rapidly growing data usage. They have been designed for readers who don’t have a technical background in the subject. While this is only a very brief introduction to the subject, these handbooks should hopefully provide a useful overview. 4 The titles in this series are: Introducing radio spectrum Introducing spectrum management Managing spectrum for growing data The spectrum policy dictionary 5 1G The first generation of ‘cellular’ mobile phone systems used in the late 1970s until the early 1990s. These analogue-based systems were replaced by 2G digital mobile systems - most notably GSM. Examples include AMPS (Advanced Mobile Phone System), NMTS (Nordic Telecommunication System) and TACS (Total Access Communications). 2G The second generation of ‘cellular’ mobile phone systems which appeared in the 1990s were the first to employ digital coding. The vast majority of 2G mobile networks around the world use GSM technology. However, there are other 2G systems including D-AMPs, PDC, iDEN and most notably cdmaOne which continues to be used by some operators around the world. 2.5G see GPRS 2.75G see EDGE 3G The third generation of ‘cellular’ mobile phone systems were the first to be designed from the outset to support high speed data services as well as voice. The most dominant system used is WCDMA which was deployed by the operators which previously used GSM. However, other systems are used including CDMA2000 (largely by operators that previously used cdmaOne) and the Chinese system TD-SCDMA.
