Connectivity

SBDist

Current radio systems are optimized with regard to capacity and range. However, certain applications of wireless systems require fast and reliable communication over short distances. The challenge of these systems is to manage with a minimum time delay (latency) while at the same time being very reliable and insensitive to interference.

In the course of the project "Sichere und latenzarme Breitbandübertragung über kurze Distanzen " (SBDist), a new wireless technology is to be developed allowing a reliable and fast transmission of large data volumes between moving units over a distance of a few meters. For this purpose, various methods are combined which optimally exploit the available radio channel. Suitable antenna systems are combined with innovative modulation and coding techniques to meet the increased demands for latency, signal fluctuation and noise immunity.

The radio system to be developed shall be used in a wide range of applications: for example, in the communication between individual passenger train wagons of Deutsche Bahn. For this purpose, a demonstration system is developed, which shows the new possibilities under realistic operating conditions. The project is accompanied by further associated partners, which can supplement the requirements of the railway as well as transfer the concept to the operation of commercial vehicles. This ensures that the new wireless technology is geared to the needs of real application fields.

The project investigates control processes in industrial applications, which are robust and allow only an extremely small latency. In future, data can be exchanged reliably and safely between moving units, machines or machine parts. The results can also be used in other fields of application, e.g. in the communication between tractor and semi-trailer or machinery in agriculture. This provides a flexible and robust alternative for cable and plug-in connections that are susceptible to error and wear in demanding applications.
