A robust and fast radio connection for safety-relevant applications
NTStarEcho is a Bluetooth® Low Energy (BLE)-based system architecture for safety-relevant applications with a rating of up to SIL 3.The innovative wireless network characteristic with cooperating echo nodes and a flexible communication protocol enables a uniquely robust wireless communication with a minimum of latency.
Thanks to complete scalability and variable performance optimisation, e.g. an adjustment of the latency, redundancy and energy consumption to meet specific demands, the NTStarEcho is perfectly suited for a wide range of applications, for example in robotics, industrial automation, control of medical devices or in the field of autonomous vehicles.

NTStarEcho is based on a redundant star typology. The transmission of messages between the network participants (device nodes) is implemented via a defined number of echo nodes. This procedure enables variability in the planning of the energy consumption, latency and transmission reliability (redundancy). For example, by increasing the amount of connected echo nodes, the latency is reduced and the transmission reliability is increased – at the same time, the energy consumption for device nodes is increased.
The NTStarEcho architecture can be set using a variety of different readily available BLE components. Use of the NewTec component NTSecureNode BLE 100 enables – in addition to a fast realisation and optional monitoring of essential room parameters – a high level of information security and a functional safety rating of up to SIL 3.
The system architecture offers high availability levels in connection with NewTec components. System failures due to losses of connection are as good as gone.
