Hytera Mobilfunk has won a contract to upgrade the existing TETRA radio system for the Leipziger Verkehrsbetriebe Group in Germany. Leipziger Verkehrsbetriebe operates 13 tram system lines and 61 bus lines for the local public transport service in the Leipzig metropolitan area, carrying roughly 135 million passengers every year
The deal is part of a wider contract being undertaken by general contractor Trapeze Group, in cooperation with systems integrator company Comtechnik Funk, to upgrade the existing communication system and install a state-of-the-art operational control system.
Hytera Mobilfunk will enlarge the current TETRA radio system with the addition of a redundant switching node and three DIB-500 R4.1 TETRA radio base stations, including an outdoor base station for use in a railway station.
The TETRA radio system is integrated through its own multifunctional A-CAPI interface into the existing ITCS infrastructure. Along with the radio system, Hytera Mobilfunk is also responsible for the project management, planning, configuration, commissioning and the documentation.
The new solution is designed to modernise communication between trams and buses and the control room, as well as to upgrade the electronic passenger information displays.
The TETRA radio system will be used to transmit the passenger and connection information in real time to the trams and buses, where it will be shown on the existing multifunctional displays inside the transportation vehicles.
The TETRA radio system will also continue to be used for communication between the drivers and the control room, as well as for the road and trackside displays at the tram and bus stops.
The new communication system will provide passengers with better services including shorter journey times and improved information, while also enhancing the level of travelling comfort. The project will be funded with money from the European Regional Development Fund (ERDF) and the Free State of Saxony.
