Time-Sensitive Networking in IEEE 802.11be: On the Way to Low-latency\n WiFi 7

Abstract

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