Couse Overview

The course after discussing the GSM functional overview, explores signal transmission process in GSM along with the basic telecommunications services provided by GSM networks. Then course goes on to discuss, signal propagation and transmission concepts in GSM networks and transmission impairments and countermeasures, concept of channels in GSM. The course deals with fixed transmission design aspects of GSM access and core networks. Link engineering and cell planning is discussed in details and a number of practical cases are analyzed to grasp the engineering steps involved towards the deployment of a functional GSM network.

Through the course, the emphasis is on developing a really sound understanding of the GSM design principles through worked solutions based on real network deployments. The course also looks into the deployment of GPRS as an overlay over an existing GSM network, engineering design considerations and migration paths towards third generation mobile systems.

Key Benefits
