Novel wireless systems are often first evaluated by simulation, before prototypes are tested and the concepts are standardized. In order to ensure relevant simulation results, the wireless channel has to be modelled properly and application oriented. Currently, only few considerable industrial channel models are available. The IEEE 802.15.4a model is the most commonly used. CM 7 applies for LOS modelling...
Wireless technologies gain importance in various fields of industrial communication as they facilitate control and data acquisition tasks. In this context, Parallel Sequence Spread Spectrum (PSSS) is a promising new approach. The parametrization of a PSSS system is very flexible and thus can be precisely adapted to the application's requirements. Independent of the PSSS parametrization, the transmission...
Communication in industrial applications like factory automation (FA) demands very low latency combined with high reliability. Since state of the art wireless technologies are not entirely fulfilling FA requirements, novel approaches are being developed.
Industry 4.0 is a subject of current relevance which targets detailed information acquisition from industrial production processes. Wireless communication to ease this acquisition process is highly interesting but suffers today from problems of low reliability, high latency and small flexibility. ParSec addresses these subjects by investigating an innovative, CDMA based approach with very low latency...
Communication in industrial applications like wireless factory automation demands high reliability and low latency. Due to the fact that state of the art wireless sensor networks do not entirely fulfill the high requirements, new approaches have to be developed. An ultra-wideband system in combination with a MAC protocol for time-critical applications seems to be a promising approach. This paper introduces...
Communication in industrial applications like wireless factory automation demands high reliability and low latency. Since state of the art wireless sensor networks do not entirely meet the high requirements, new approaches have to be developed. An ultra-wideband system in combination with a suitable MAC protocol seems to be a promising approach. The proposed ultra-wideband system already provides...
