From 2019, Airbus will embark on the modernization of the PMR (Professional Mobile Radio) network of the Berliner Verkehrsbetriebe (BVG) public transport company. By 2020, the PMR provider will have overhauled the network infrastructure and converted the system to Internet protocol (IP).
Airbus has also concluded a service agreement with the BVG until 2025. Airbus will provide the Berlin-based company with advice and support over the course of the modernization process. The entire contractual package also comprises, alongside the technical retrofitting, the supply of the latest technology, such as an IP-based switch and an in-service maintenance and service provision.
Communicate More Securely
The partners have also agreed to the possibility of progressively expanding the network with other base stations and to run these using the simulcast technology. Simulcast, also called Single Frequency Network, allows all base stations to transmit on the same frequency. This means that signals can be propagated very well over large areas.
With the upgraded Tetrapol network, drivers and the control centre will be able to react more efficiently to all kinds of situations
Since the network was rolled out in 2001, Airbus has partnered with BVG and, with its modern radio technology, it will make a further important contribution to the efficient running of Berlin's bus traffic. With the upgraded Tetrapol network, drivers and the control centre will be able to react more efficiently to all kinds of situations and to communicate more securely.
Safe Transport System
The modernization also implies an increase in the system’s capacity so that it can transmit even greater volumes of data. For approximately 2,100 radio users at the BVG, the Tetrapol network was made even more robust and user-friendly.
A total of around 14,600 people work for the BVG and its subsidiaries to provide an environmentally friendly, reliable and safe transport system for more than a billion travellers each year. To coordinate the complex bus traffic in Berlin, the company built the Airbus Tetrapol network around nine base stations. Buses run on more than 150 lines over a catchment area of approximately 1000 km². The BVG also operates night buses on more than 60 lines, along with 22 tramway lines.
