These services can be based on a dedicated broadband network, on commercial services with a Secure Mobile Virtual Network Operator (MVNO), or on a combination of the two. The use of TETRA/Tetrapol can continue while mobile broadband services are introduced. That is why a hybrid network is the better - and also a more cost-effective - approach. Let’s be real - it would be risky to replace an existing capable radio communications network with an alternative that does not necessarily meet the critical requirements. This has led many to ask, what is the best strategy for the broadband evolution? Would you like to comment on this story? Find our comments system below.There are several options for radio network owners and operators to introduce broadband services. The BVG also operates night buses on more than 60 lines, along with 22 tramway lines. Buses run on more than 150 lines over a catchment area of about 1,000 square kilometers. To coordinate the complex bus traffic in Berlin, the company built the Tetrapol network around nine base stations.
For about 2,100 radio users at the BVG, the Tetrapol network was made even more robust and user-friendly.Ī total of around 14,600 people work for the BVG and its subsidiaries to provide transport for more than 1 billion travellers each year. The modernization also increases the system’s capacity so that it can transmit even greater volumes of data. 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. Simulcast allows all base stations to transmit on the same frequency, allowing signals to be propagated well across large areas. The partners have also agreed to the possibility of expanding the network with other base stations and running these using simulcast technology.
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. Airbus will provide the company with advice and support during the upgrade process. Airbus has also concluded a service agreement with the BVG until 2025.
