Description
This course provides a comprehensive understanding of mobile train radio communication systems used in Railways, with a special focus on VHF communication and GSM-R technology. It is designed to equip students and railway professionals with both theoretical knowledge and practical insights required for safe, reliable, and efficient railway operations.The course begins with an overview of the present scenario of train radio communication on Railways, highlighting the need for mobile and emergency communication in day-to-day operations. It then covers VHF mobile radio communication, including its applications, modes of operation, frequency allocation, operational guidelines, installation practices, maintenance procedures, testing requirements, and failure reporting.Students are introduced to the fundamentals of cellular mobile communication systems, such as cellular geometry, clustering, and frequency reuse, followed by an in-depth study of GSM technology. Topics include GSM architecture, network elements, radio interfaces, logical channels, digital transmission, call management, and handover processes.A major part of the course is dedicated to GSM-R (Global System for Mobile Communications - Railway). Learners will study GSM-R applications in railway operations, emergency communication, shunting, maintenance, signaling support, and train diagnostics. The course explains GSM-R network architecture, quality requirements, special railway features such as functional addressing, location-dependent addressing, eMLPP, VGCS, and VBS, as well as implementation options and system planning.The course also provides practical exposure to GSM-R BSS equipment, including BTS, BSC, TRAU, Radio Commander, LMT, and various GSM-R mobile terminals such as cab radios and handhelds.By the end of this course, learners will be able to understand, operate, maintain, and analyze railway mobile communication systems, making them well-prepared for roles in Signal & Telecommunication engineering, railway operations, maintenance, and safety-critical communication environments within Railways.
