Towards a reliable and high-speed wireless complement to TTEthernet

TTEthernet is a general purpose communication infrastructure for applications with real-time and/or fault-tolerance requirements. It is based on Ethernet as standardized by the IEEE and allows the integration of mixed-criticality applications in a single physical network. However, currently TTEthernet only operates in wired network settings. With growing industrial demand of the design freedom that comes with wireless communication solutions we are interested in extending TTEthernet to a wireless communication paradigm. In this paper we review the state of the art in deterministic wireless communication approaches. We deduce quality criteria for wireless networks from industrial use cases and outline candidates for a wireless complement to wired TTEthernet.
