Introduction to GSM and GPRS
With the continuing role out of 5G, the second generation technologies of GSM and GPRS still play an important part in the global communication landscape. In this short course, we aim to provide a comprehensive introduction into the two systems and in so doing, explain how they support circuit switched voice and packet switched data traffic. Mobility is discussed in addition to reviewing how roaming is supported for both GSM and GPRS.
