GSM-Railway is a wireless communication system developed specifically for railway communication. GSM-R technology was developed in an EU-funded MORANE (Mobile Radio for Railways Networks in Europe ) project. The project's goal is to develop a uniform digital radio system for European railroad traffic. GSM-R is a platform for voice and data communications as well as for traffic control system.

With AJA's GSM-R handheld ORP100 and radio mobile module UX800, the railway communication will tremendously enhance between ground personnel and in-train staff.

GSM-R is currently being introduced as the European standard for railway communications and is already in commercial use in several European countries. Several countries outside of Europe, e.g. China and India , decided already for GSM-R as their railway communication system. This allows for a single international communication standard for train communication and also improves interoperability between the various railway companies at international level.
