RF Cellular Networks
GSM (Global System for Mobile Communication)
Duration: 2 Days

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

This two-day course is developed to offer telecommunications professionals a sound understanding of GSM technology and to discuss major engineering steps involved when planning and deploying GSM networks. Also the course objectives are to investigates GSM (2G) possible migration paths towards 3G and analyze the impacts of GPRS over GSM in terms of coverage, capacity and enhanced services.


Basic knowledge of radio communication.

Who should attend

Telecommunications professionals requiring sound understanding of functional and, operational of GSM technology along with GSM network design and planning.
