We are experts for Ultra-Available Time-Critical Wireless Technology. Our major product is a communication layer/protocol we call EchoRing™.
EchoRing™ leverages cooperative communication primitives to achieve ultra-reliable performance, while a token-passing scheme allows for guaranteed medium access in a decentralized fashion. EchoRing™ operates on top of different physical layer transmission schemes, and therefore scales to different delay requirements. Further aspects of the technology comprise interference detection and avoidance, the identification of critical communication states (to vacate the used channel swiftly) as well as integrated security features.
In recent years, the wireless networking research community has intensified efforts to deal with so-called machine-to-machine type (M2M) application scenarios. These scenarios differ from traditional human-based application scenarios, as in the case of M2M embedded devices are autonomously communicating in order to fulfill control tasks in the environment. Therefore, latency, reliability and scalability of the communication processes are becoming very important in contrast to more traditional performance metrics like throughput and spectral efficiency.
Application scenarios in M2M also relate to communication within highly integrated technological products, rather than between such systems. This refers for example to the control data traffic within planes, light-passenger cars and commercial vehicles, and the communication among them and its vicinity in the context of vehicle to anything (v-to-x). Very high quality standards (safety and security) must be fulfilled here, leading to the fact that by today this data traffic is conveyed over inflexible, costly, and heavy copper harnesses.
The above is especially true for industrial IoT / Industry4.0 scenarios in the case of critical communication, as cables are neither a practicable nor economically feasible option to connect the billions of devices those ideas are based on.
The EchoRing™ communication layer runs on selected commercial-of-the-shelf (COTS) radio hardware components – which renders it flexible and easy to integrate, and especially competitive. This also means that existing wireless hardware components might be reused to create a high-class radio network.
And EchoRing™’s performance grows stronger with every new generation of wireless technology.
