  Short time after the official launch of WiFi 6, IEEE 802.11 working groups
are already designing its successor in the wireless local area network (WLAN)
ecosystem: WiFi 7. With the IEEE 802.11be amendment as one of its main
constituent parts, future WiFi 7 aims to include time-sensitive networking
(TSN) capabilities to support low latency and ultra reliability in
license-exempt spectrum bands. This article first introduces the key features
of IEEE 802.11be, which are then used as the basis to discuss how TSN
functionalities could be implemented in WiFi 7. Finally, benefits and
requirements of the most representative low-latency use cases for WiFi 7 are
reviewed.
