Wireless TSN: PTP Time Synchronization over IEEE802.11

Lecture electronica Conferences > Wireless Congress > Session 10: Technology

11:30-11:55 h | Virtual

The introduction of industry 4.0 increased the need for a global solution for real-time communications. Time Sensitive Network (TSN) is currently the best candidate to fulfill this requirement since it is standardized and based on the conventional Ethernet technology. This means, TSN is essentially a wired solution. However, the industrial market largely makes use of wireless communications as well. Therefore, the demand for a real-time wireless network that satisfy both determinism and mobility requirements is increasing and pushing toward wireless TSN. Whether it is wired or wireless, the main element for TSN is time synchronization. This presentation discusses the process of time synchronization over IEEE 802.11 (WLAN). First, we present the standard time synchronization method described in IEEE 802.1AS which is based on a profile of the Precision Time Protocol (PTP) and called generalized PTP (gPTP). Afterwards, we describe an innovative method used as an alternative way to achieve highly precise synchronization accuracy over WLAN. Finally, this discussion is concluded by showing some measurement results obtained from different time synchronization tests performed in our labs.
