Source: CDMA CAPACITY AND QUALITY OPTIMIZATION Chapter CDMA Now and in the Future In August 2002, Sprint PCS activated the first third-generation (3G) cdma2000 1x net- work across the United States. Yesterday, service was briefly unavailable in San Antonio, Texas, probably as the base station was switched over. For the first time, 3G code divi- sion multiple access (CDMA) is a reality across an entire large national network. Tech- nically, it appears sound. Will it demonstrate the 50 to 100 percent increase in call ca- pacity expected? How much of that call capacity improvement will be realized before customers are using cdma2000 cellular telephones? Will customers have enough interest in data services to make them profitable? These major questions face the industry as a whole and face each company as the market reaches saturation and the industry moves out of its initial growth phase and into its mature, competitive phase. Growth will become more a matter of market share than a matter of attracting new customers to the industry. There are a host of minor questions as well. In the first section of this chapter, "CDMA Now," we will look at these issues across the globe. In the second section, we will look at some of the challenges and opportunities CDMA faces in the future. 49.1 CDMA Now CDMA faces different market challenges and different technical challenges in each p
