Slide 3 Leading Standards CDMA2000 1X IMT-2000 W-CDMA Slide 4 What is CDMA? • Code Division Multiple Access (CDMA) is a digital wireless technology that was pioneered and commercially developed by QUALCOMM. • CDMA works by converting speech into digital information, which is then transmitted as a radio signal over a wireless network. • Using a unique code to distinguish each different call, CDMA enables many more people to share the airwaves at the same time - without static, cross-talk or interference.

  • 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.

For the past several years, mobile data traffic such as internet access, the downloading of music and video communication has been nearly tripling every year. With the popularity of smartphones, mobile data traffic will increase 200 times in the 7 to 8 years upto 2020.There are high expectations that Long Term Evolution (LTE) which is known as 3.9G wireless system will be a new service platform that can support a huge amount of mobile data traffic. This paper describes the features, technology and network architecture of LTE & also provides an overview of next generation telecommunication network LTE, which is started commercially in December 2010 in Japan (started by DOCOMO), realizing high speed wireless access. It also outlines the further trends towards a further speed increase. Keywords-Circuit Switching, GSM, HSPA, LTE, Packet Switching, WiMAX I.
