Meaning for players
Operators For cellular operators, upgrading networks to some architecture that can handle packet-based applications means investments but also several commercial opportunities. Operators face the difficult question of network choices in the next couple of years. Some form of packet networking capability is needed in advance of the third generation, but there seems to be no agreement within the players in the operating business, how and when the infrastructure investment should take place. In addition, the target market and the potential user groups of the new services enabled by packet-switched networks are not clear. One view is that investing in GPRS will help operators learn about new applications, services and user requirements for the third-generation as well as accommodate users to the coming new services. The implementation of GPRS requires changes in the operators' network equipment in the base stations and base station controllers. It means making modifications to the core network: new routers need to be added so that traffic can be passed efficiently and the radio network needs to be modified in a way that it works both in a packet-oriented and circuit-oriented way. Good news for the operators is that GPRS is being designed to work within the existing GSM infrastructure. It means that GPRS coverage can be introduced quickly. GSM is the most advanced cellular system for the implementation of packet switched data transmission. GPRS will permit more efficient use of the network than circuit radio data, since packet architecture offers higher speeds and better use of the radio resource. It also gives a chance for operators to try new charging methods, that is, charging by data volume instead of duration, which may lead to offering lower tariffs for users. Terminal Vendors
