will also be to a more mobile community. In fact, the study indicates that by 2005, more wireless devices will be used for the Internet than PCs on the Net, as shown in Figure 2-3. This form of growth is again a driver that will force the rapid deployment by carriers and manufacturers alike. The GPRS Story The GPRS is a new service that provides actual packet radio access for GSM and Time Division Multiple Access (TDMA) users alike. The main benefits of GPRS are that it reserves radio resources only when data is PCs on Internet WAP Handsets Cellular Subscribers Downloaded from Digital Engineering Library @ McGraw-Hill (www.digitalengineeringlibrary.com) Copyright © 2004 The McGraw-Hil Companies.

Figure 2-4 is a basic stepping-stone description of the GPRS story. The increased functionality expected from GPRS will decrease the incremental costs to provide the data services, which will increase the pen- etration of the data services, among the consumers and business users alike. Additionally, GPRS will improve the quality of data services measured in terms of reliability, response time, and features available. Unique applica- tions will be developed in the future that will attract the broad base of mobile users and enable the individual providers to offer differentiated ser- vices. One way that GPRS improves upon the capacity capabilities of the network suppliers is to share the same radio resources among all mobile stations in a cell, thus providing effective use of scarce resources.
