GPRS is the first technology to introduce packet switching to the world of mobile communications in a meaningful, large-scale context. As such, it adds two major, equally important, elements, viz., (i) packet switching over the air interface and (ii) enhancements to the core to support packet switching on a GSM network.
Implementing packet switching over a highly unreliable and time-varying channel, such as is typical in today’s wireless communications, is not an easy task. In this GPRS Training – General Packet Radio Service Training course, you will learn how GPRS tackles this problem and achieves a reasonable performance using packet switching over the air interface. You will also learn the new interfaces that were necessary for the fixed portion of the network to support an end-to-end packet-switched service. We will not be shy about highlighting the shortcomings of GPRS, some of them quite serious. We will go on to learn which of these shortcomings can be mitigated (along with how that’s done) and which are unsolvable within the framework of GPRS.
