Abstract
Since the mid-1990s, however, the importance of the Internet has been constantly increasing. GPRS, the General Packet Radio Service, enhanced the Global System for Mobile Communications (GSM) standard to transport data in an efficient manner and enabled wireless devices to access the Internet. With Enhanced Datarates for GSM Evolution (EDGE), further additions were specified to improve speed and latency. This chapter discusses the advantages and disadvantages of GPRS and EDGE compared to data transmission in classic GSM and fixed-line networks. It focuses on how GPRS and EDGE have been standardized and implemented. GPRS shares a number of channels with GSM to initially request for the assignment of resources. To send packet-switched data over existing GSM networks, GPRS was designed as a packet-switched addition to the circuit-switched GSM network. GSM uses timeslots on the air interface to transfer data between subscribers and the network.
