To ensure the reliability of the urban transit system in the future, SYTRAL required a digital data radio network that transmits, above all, GPS and operating data of the vehicles. In 2006, Hytera Mobilfunk GmbH, formerly known as Rohde & Schwarz Professional Mobile Radio GmbH, received the order to implement a particularly powerful and expandable TETRA system.
