Use of WLANs based on IEEE 802.11 technology continues to grow and diversify over many market segments including residential, enterprise, industrial. More stringent requirements are emerging to meet the demands of new applications (e.g. augmented and virtual reality, proximity ranging and sensing) both in terms of throughput, latency bounds and accuracy. The very large bandwidth available in the unlicensed bands between 42 GHz and 71 GHz, combined with the widely used 2.4, 5 and 6 GHz bands, is a great opportunity to help meet these requirements even in the densest environments. Enabling non-standalone operation in the unlicensed bands between 42 GHz and 71 GHz in a cost-effective manner is required so that many devices can benefit from it.
This amendment defines standardized modifications to both the IEEE Std 802.11 Physical Layer (PHY) and the IEEE Std 802.11 Medium Access Control (MAC) that allows Wireless Local Area Network (WLAN) non-standalone operation in unlicensed bands between 42 GHz and 71 GHz using single-user (SU) OFDM based transmissions. The amendment requires that an 802.11 device supporting this amendment also supports at least one of the 2.4 GHz to 7.25 GHz (sub-7 GHz) unlicensed bands. The amendment expands the multi-link operation defined in the sub-7 GHz band specifications to support non-standalone operation in the unlicensed bands between 42 GHz and 71 GHz.
This amendment on PHY and MAC operation in unlicensed bands between 42 GHz and 71 GHz, leverages or reuses existing PHY and MAC specifications defined for the operation in sub-7 GHz bands, e.g. SU transmission PPDU format and MAC frames, and defines bandwidth modes operating in non-overlapping channels.
This amendment provides coexistence mechanisms with legacy IEEE 802.11 devices operating in the unlicensed bands between 42 GHz and 71 GHz.
The Task Group s kickoff meeting was held on 26 February 2025. For details, please refer to the meeting agenda.
The next meeting is scheduled in the 2025 March plenary.
