GSM-R stands for Global System for Mobile Communications-Railway, a digital communication system for railways:
- Purpose
GSM-R is a secure, reliable, and mobile system that provides voice and data services for railway operations. It’s used by drivers and signallers to communicate with each other, and is a sub-system of the European Rail Traffic Management System (ERTMS).
- Benefits
GSM-R improves safety, performance, and passenger experience. It also helps to create a more sustainable and digitally-enabled railway network.
- Features
GSM-R offers a variety of features, including:
-
Functional Addressing: An alias system for calling someone registered on the GSM-R network
-
Location Dependent Addressing: A routing system for calling the most appropriate controller based on the train’s current position
-
Shunting Mode: A mode for when users are working on the tracks
-
Performance
GSM-R is designed to perform at speeds up to 500 km/h (310 mph) without any communication loss. However, its maximum transmission rate is only 9.6 kbit/s, which is too low for real-time applications or emergency communication.
