Analogue technologies were dominant in the cellular market up to 1997, when their global market share was exceeded by that of 2G digital technologies. The last 10 years have seen a phenomenal growth of the cellular penetration worldwide, which has defined the shape of the 2G technologies global market share as displayed in figure 1.
Today, the convergence of 2G technologies towards the 3G evolution path is relatively clear. The entities that are representing and driving the evolution of 2G technologies have endorsed the 3G/UMTS evolution path:
• The GSM Association, representative of the GSM operators worldwide, is a market representative of the 3rd Generation Partnership Project (3GPP) and fully supports 3G/UMTS evolution path.
• 3G Americas, a wireless industry association dedicated to the Americas, supports the seamless deployment of GSM, GPRS, EDGE and UMTS throughout the Americas and fully endorses the migration of TDMA operators to the GSM family of technologies. The transition from TDMA to GSM technologies for operators is helped by the GAIT standard functionality (GSM, ANSI-136, Interoperability Team) that enables interoperability between TDMA and GSM technologies.
• In Japan, the two most important PDC operators (NTT DoCoMo and J-Phone), which on October 1st, 2001 covered 75.7% of the Japanese subscriber base, have selected UMTS WCDMA technology for their 3G evolution.
The alternative 3G evolution path to UMTS is the one endorsed by the CDMA Development Group (CDG), which supports an evolution to 3G based on cdmaOne technology. cdmaOne was initially developed in the United States and soon adopted in other regions. Figure 2 shows the market share cdmaOne technology holds in different global regions. Although cdmaOne has been introduced in most of the regions worldwide, only in America, especially in the United States, and to some extent in Asia Pacific, fundamentally in Korea, has it developed an important momentum.
Additionally, many current cdmaOne operators are analysing the possible migration paths to UMTS. Such migration can be done through the migration to GERAN (GSM/EDGE) with the later integration of UTRAN (WCDMA) or it can be done through the direct introduction of UTRAN. This last option is however dependent on the cellular operator licensed bandwidth, since WCDMA technology is currently not supported in the 800 MHz band, the future availability of dual mode cdmaOne/WCDMA terminals and the integration effectiveness of the technologies.
