Introduction to GSM and GPRS

As we move towards the launch 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. Finally, GPRS will be discussed in light of the rise of the Internet of Things and the modifications that have been introduced to support machine to machine based communications.
