Today no one doubts that the introduction of GSM represented a revolution in mobilecommunications. As this book goes to press, there are more than 773 million GSM usersworldwide and the number is growing by the minute. This revolution, which has takenplace over the last 12 years, has had an enormous impact on our daily lives. Mobiletelephony has changed the way we communicate and the way we do business. Friendsand colleagues can be reached almost anywhere at any time, we are no longer tied todesk-top machines for e-mails and faxes, and the mobiles themselves are replacing notonly telephones but also dictaphones, personal organizers and phone books.‘Convergence’ has been the buzzword in recent years. The above is just the beginningand GPRS is the key. As multifunction mobile devices replace cellphones, PDAs andnotebook PCs, there will be an ever increasing demand for bandwidth. Home Internetusers are used to the level of service offered by 64 kbits−1 ISDN or the higher ratesoffered by the various DSL services. These users will increasingly demand the same levelof service from their mobiles, and as the volume of users goes up, content and serviceproviders will respond and the network operators will have to provide the capacity.Originally, 3G was seen as the means to satisfy the demand for bandwidth and GPRSwas viewed by many simply as a stepping stone on the way from narrowband GSM towideband UMTS. However, the worldwide delay in 3G rollout has led to GPRS beingseen in a different light, particularly with the development of E-GPRS. The promise oflow-cost reliable mobile Internet access has led to many operators implementing GPRS,but, whereas GSM was seen as a communications technology, GPRS is seen more asan enabling technology. The ability to run an application on a mobile device that cansend and receive packet data at high speed makes possible such things as mobile Internet,remote device control, multi-player gaming, location-dependent information services, andm-commerce.GPRS will continue to change the way we live, just as GSM has already done.
