EGPRS Operations - 3 days
This course builds upon our course GPRS Operations and provides the attendee with a thorough grasp of the principles and practice of EGPRS Operations.
Day 1
Introduction
The differences between GPRS and EGPRS. Modifications to the GPRS Protocol Stack.
Modulation
GMSK in GSM, GPRS and EGPRS. The principles of GMSK, continuous phase shift as FSK, required bandwidth, available customer data rates.
8-PSK in EDGE and EGPRS. Limited continuous phase shift as FSK, required bandwidth, available customer data rates.
An Introduction to data flow through the EGPRS Protocol Stack.
Data flow for Modulation and Coding Systems 1-6
Data flow for Modulation and Coding Systems 7
Data flow for Modulation and Coding Systems 8-9
Recognizing burst types, modulation types and Coding and puncturing types.
New RR Information and Commands for EGPRS Operations
SI for EGPRS
