    Precision measurement of the application-dependent current consumption of a wireless transceiver chip in the time and frequency domain
    (Copernicus Publishing, 2022-06-13) ; ;
    Modern production concepts generate a demand for reliable, energy-efficient, fast, and secure wireless communication solutions. Therefore, the current consumption should not increase substantially due to additional cryptographic operations. This paper shows a principle current measurement method that is exemplary of a transceiver for the IO-Link Wireless protocol. Low-pass filtering and single-sided amplitude spectrum analysis are used to evaluate the main information of the current measurement. An uncertainty estimation is realized using statistical measurement data and considering the measurement setup in order to approximate the combined standard uncertainty. The results show that the current consumption only increases slightly when using additional cryptographic operations. This can be measured with acceptable uncertainty.

    Study of a Safe and Secure Ecosystem based on IO-Link Wireless and a 5G Campus Network
    Wireless networks support highly flexible manufacturing processes and are recognized as a crucial pillar towards the digitization of industrial production (automation). While 5G is currently being marketed as universal solution for future wireless communication, high density of sensor and actuator nodes in industrial manufacturing environments with respect to latency times and reliability, still represents an enormous technical challenge. In the field of production automation standards, IO-Link Wireless (IOLW) is already in operation offering energy-efficient and cost-effective solutions, even with battery-powered smart sensor devices. In this paper, the deterministic ultra-reliable low-latency communication (URLLC) features of 5G are combined with the outstanding performance characteristics of IOLW with respect to robustness and latency to realize even highly demanding safety applications in industrial environments.
