Wired real-time network deployments based on time-sensitive networking (TSN) are becoming increasingly popular in several application fields including industrial automation and the automotive area. This is to a great extent due to the scheduled traffic (ST; IEEE 802.1Qbv), a TSN mechanism that precisely triggers transmissions at pre-defined instants from a set of independent hardware queues. Unfortunately, the wireless counterparts based on IEEE 802.11 (Wi-Fi) currently lack standardized or functional solutions that would be able to fulfill strict real-time requirements. This work proposes the use of ST over IEEE 802.11, taking advantage of an existing but overlooked mechanism from commercial off-the-shelf (COTS) equipment. An extensive set of tests, spanning different implementation configurations, traffic patterns, and levels of interference evaluates the proposal in terms of reliability and delivery delays and serves as a proof of concept. The tests also evaluate the much-needed clock synchronization quality of an out-of-the-box software-only implementation of the precision time protocol (PTP) due to its relevance in enabling ST.
