What is WiFi 8 UHR standard 802.11bn ?
As on 2024, when IEEE 802.11be task group is at the stage of completion of standardizing wifi-7 standard, IEEE 802.11 WG has starded introduction of next generation wifi-8 standard. Ultra High Reliability (UHR) study group, is actively engaged in formulating a Project Authorization Request (PAR) for the forthcoming major Wi-Fi release, Wi-Fi 8
The 802.11 WG will investigate Physical layer and MAC layer technologies to improve reliability of WLAN connectivity, reduce latencies, increase manageability, increase throughput including at different SNR levels and reduce device level power consumption.
The joint interworking of multi-link operation and spatial-domain multi-AP coordination can help to achieve ultrahigh reliability in WiFi-8 network.
Refer difference between WiFi 7 and WiFi 8 >> WLAN standards.
Following features have been planned to be incorporated in WiFi 8 technology based devices.
These are the key features planned to be added in WiFi-8.

Benefits or advantages of WiFi 8
Following are the benefits or advantages of WiFi 8:
➨It offers Seamless Connectivity via Distributed Multi-link Operation (MLO).
➨It supports mmwave bands in addition to 2.4 GHz, 5 GHz and 6 GHz supported in wifi-7 and hence
offers abundant spectrum. Moreover it can provide Gbps data rates which is faster than traditional
microwave and RF spectrum.
➨It controls worst case delay using AP coordination.
➨Due to higher channel bandwidth and 8K QAM OFDMA modulation ,
it can offer higher data transfer rate of about 100 Gbps in comparison to previous wifi-7 standard.
➨It improves reliability of WLAN connectivity by reducing latencies.
Conclusion : WiFi 8, officially known as IEEE 802.11bn, brings significant advancements to wireless networking with
notable benefits and key features.
With a focus on higher modulation 8K QAM, mmwave spectrum allocation and reliability,
WiFi 8 supports multi-gigabit speeds, making it well-suited for bandwidth-intensive applications.
Overall, WiFi 8 represents a substantial leap forward in wireless communication, offering a more robust and reliable
connectivity solution for evolving digital ecosystems.
