“…The PDA technique we analyze here is called Timed Duplicate Deferral (TDD). A similar solution, not coupled with early termination, was proposed in [23]. TDD is much simpler than the Dynamic Duplicate Deferral (DDD) technique presented in [17], as its operation does not rely on any indication provided at runtime by the MAC layer.…”

Seamless redundancy layered atop Wi-Fi has been shown able to tangibly increase communication quality, hence offering industry-grade reliability. However, it also implies much higher network traffic, which is often unbearable as the wireless spectrum is a shared and scarce resource. To deal with this drawback the Wi-Red proposal includes suitable duplication avoidance mechanisms, which reduce spectrum consumption by preventing transmission on air of inessential frame duplicates.In this paper, the ability of such mechanisms to save wireless bandwidth is experimentally evaluated. To this purpose, specific post-analysis techniques have been defined, which permit to carry out such an assessment on a simple testbed that relies on plain redundancy and do not require any changes to the adapters' firmware. As results show, spectrum consumption decreases noticeably without communication quality is impaired. Further saving can be obtained if a slight worsening is tolerated for latencies.

The industrial wireless automation sector exhibitsa huge market growth in the last years. Today, many applicationsalready use wireless technologies. However, the existingwireless solutions do not yet offer sufficient performance withrespect to real-time and reliability requirements, particularlyfor closed-loop control applications. As a result, low latencywireless communication technologies will bridge the gap andcan become a key factor for the wide-spread penetration ofwireless in industrial communication systems. It is therefore themain goal of this paper to provide a comprehensive overviewon requirements, current solutions, and challenges as well asopportunities for future wireless industrial systems. Thereby,presented requirement figures, analysis results, and performanceevaluations are based on numerous practical examples fromindustry
