Specialization in Public Transport
TRONTEQ’s focus is entirely on public transport. As a result, we want to offer this industry the maximum benefit from Ethernet technology. In other words, our greatest ambition is to develop products that make it easier for mass transit operators to digitize their vehicle fleets over IP networks. To achieve this, we value dialog and exchange with you, our customers. On the one hand, we provide you with advice and support. On the other hand, we listen to your pain points and wishes, which are the driving force behind our product development. Because we want to get better and better and offer our numerous customers ever smarter solutions – tailored to the needs of the public transport industry.
Specialization in Ethernet switches

Ethernet technology stands for the simplification of complex processes through networking. Numerous industries benefit from this, including the public transport sector. Ethernet switches are the basis of every network – they fulfill the function of links between the network participants. Since they play a fundamental role, their characteristics are all the more important.

With the ROQSTAR product series, we have created various Ethernet switches for use in public transport that combine the durability of a rock (ROQ) with the extraordinary qualities of a star. Our ROQSTARs interconnect IP-based components within a network in public transport buses and streetcars. And because they have been specially developed for public transport, they also have other advantages that simplify installation and operation in the vehicle. And they are getting better at it. Because TRONTEQ develops switches with the aim of pushing forward the digital transformation of public transport.

Compliance With All Relevant Norms And Standards

From fire protection to interoperability – ROQSTAR Ethernet switches meet all norms and standards for public transport vehicles. All our devices bear the UN E-mark (E1) and are thus approved for use in road vehicles. ROQSTAR Gigabit Switches also meet the requirements for installation in rail vehicles. These can be recognized by the EN 50155 mark. 

With its membership in the international organization for interoperability in public transport ITxPT, TRONTEQ has committed itself to offering only devices that comply with firmly defined technical standards. Not only is the compatibility of our Ethernet switches ensured – we are also committed to standardizing IP communication in public transport instead of being dependent on proprietary and vendor-specific software.
