The Global System for Mobile Communication (GSM), General Packet Radio Service (GPRS) and Enhanced Data Rate for Global Evolution (EDGE) are the most dominant mobile wireless technologies. In GSM the air interface supports circuit-switched connections for voice and low data-rate services. Access to Packet data networks became possible with GPRS and EDGE which also apply the packet-switching paradigm to the air interface of GSM. This course provides the details of the Layer 1 procedures and technology features in GSM, GPRS and EDGE, taking a handset-centric point of view. After a detailed look at the GSM air interface, we go on to show how the Layer 1 features of GPRS and EDGE builds on the GSM technology to make efficient use of the air interface for access to data services.
Learning Objectives
After completing this course, the student will be able to: • Describe the GSM, GPRS and EDGE technologies and their relationship to other wireless networks • Explain the channel and frame structures in GSM, GPRS and EDGE • Describe details of Layer 1 operations for GSM/EGPRS such as multi-frame structure, burst formats and synchronization • List the Layer 1 features used in all three technologies such as AMR, power control and frequency hopping • Describe the modulation and coding schemes in GPRS-EDGE • Explain how link adaptation is done for voice in GSM and for packet data in GPRS and EDGE
Intended Audience
This course is intended for those seeking a detailed understanding of the GSM, GPRS and EDGE Air Interface. This includes those in a design, test, systems engineering, sales engineering, network engineering, or verification role.
