Wireless TSN Tests and Use Case Demonstrations with Wi-Fi White Paper

Jun 13, 2024

Wireless connectivity enables mobility, provides scalable connectivity, and reduces the wiring costs. With the advances in wireless technologies, including Wi-Fi and 5G, a growing number of use cases have emerged that can benefit from low deterministic latency with high reliability enabled by TSN (Time-Sensitive Networking) features over wireless. Wireless use cases and requirements are discussed in the Avnu Wireless TSN MRD [1]. To support these stringent applications TSN features that enable accurate time synchronization, low latency, and high reliability with determinism are extended to both Wi-Fi and 5G. Avnu Alliance has been developing test specifications for TSN features over Wi-Fi (802.11) and 5G. This document provides an overview of the main features, use cases and initial test results demonstrating the feasibility of TSN over Wi-Fi links. Work on 5G systems with TSN capabilities is ongoing, TSN over 5G tests are expected to be covered in future publications.

AVNU Alliance members have been working on wireless TSN capabilities over Wi-Fi and 5G. This report provides a few examples of Wi-Fi TSN capabilities and experiments that demonstrate the feasibility of TSN features such as 802.1AS and 802.1Qbv over 802.11. The Wireless TSN working group has been working on test specifications for both Wi-Fi and 5G systems towards the certification program. Avnu has been hosting Plugfest events where members bring their implementations to test interoperability and conformance to TSN specifications.
