Hytera Upgrades Würzburg Tramway’s Radio System with IP-based TETRA Technology

Hytera, a world leading solution provider of Professional Mobile Radio communications, upgraded the existing radio infrastructure of Würzburger Straßenbahn GmbH with latest DIB-R5 compact base stations and IP-based Tetra technology enabling data communication of streetcars and buses on top of voice communication.

A redundantly designed IPN of the latest DIB-R5 base station which provides the software-based routing function centrally in the radio system has created a fail-safe network in Würzburg. The IPN redundancy also works to protect the voice recorder operated within the IP Node equipment rack from failures as well.

Application partner Trapeze took over the set-up of the Intermodal Transport Control System (ITCS) over the ACAPI interface provided by Hytera. The ITCS system is responsible for all communication between the control room, trains and buses and therefore plays the role of lifeline among all state-of-the-art transport companies. 

Udo Freyberg, project manager at Hytera Mobilfunk GmbH, says, "We are delighted that Würzburg Tramway has once again placed its trust in us for this upgrade and we look forward to more positive collaboration in the future."
