GSM-R (GSM-Railway) Training

The objective of the GSM-R Training & Certification program is to provide participants with a comprehensive understanding of GSM-R technology, its network architecture, and railway-specific functionalities. The course covers key concepts such as signaling protocols, mobility management, and the integration of GSM-R in railway communication systems. Participants will gain in-depth knowledge of EIRENE specifications, Advanced Speech Call Items (ASCI), and operational procedures necessary for maintaining and optimizing GSM-R networks. This training is designed to equip telecom engineers, railway professionals, and network operators with the skills required to ensure reliable and efficient railway communication services.

Training Code: NES_SK_1279

Duration: 40 Hrs/ 4 Weeks / Customized

Mode: Corporate (Instructor Led - Online / Offline / Onsite), Individual (Instructor Led - Online / Offline)
