Berlin Bus Company Upgrades Tetrapol Network
Tuesday, November 20, 2018 | Comments

In 2019, Airbus will begin modernizing the professional mobile radio (PMR) network of the Berlin-based Berliner Verkehrsbetriebe (BVG) public transport company. By 2020, the Tetrapol provider will have overhauled the network infrastructure and converted the system to IP technology.

Airbus has also concluded a service agreement with the BVG until 2025. Airbus will provide the company with advice and support during the upgrade 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.

The partners have also agreed to the possibility of expanding the network with other base stations and running these using simulcast technology. Simulcast allows all base stations to transmit on the same frequency, allowing signals to be propagated well across large areas.

Since the network was rolled out in 2001, Airbus has partnered with BVG and the upgrade will contribute to the efficient running of Berlin's bus traffic. The modernization also increases the system’s capacity so that it can transmit even greater volumes of data. For about 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 transport for more than 1 billion travellers each year. To coordinate the complex bus traffic in Berlin, the company built the Tetrapol network around nine base stations. Buses run on more than 150 lines over a catchment area of about 1,000 square kilometers. The BVG also operates night buses on more than 60 lines, along with 22 tramway lines.
