Do folks know if this increases the number of channels available for Wi-Fi 6e over 6GHz in the US, or does that require additional process?

- makiftasova 2y agoLooks like it does not allow new channels for 6 GHz Wi-Fi. 802.11be (Wi-Fi 7) already covers full range of FCC's allowed frequency range. IEEE committee may add new channels in 802.11bn (expected to be ratified around 2028, and commercial name will be Wi-Fi 8) but it also looks like a low probably, considering both 802.11ax (Wi-Fi 6/ Wi-Fi 6e) and 802.11be (Wi-Fi 7) mostly focuses on reducing the interference between different networks by reducing the collision, instead of widening the spectrum (BSS coloring, Flexible Channel Utilization etc.)
- tradertef 2y agoYes and no. It increases the number of "VLP" channels. 6GHz has 3 modes of operation: 1) VLP: can now happen in 1200 MHz (5925 MHz to 7125 MHz); previously it was only 850 MHz. Very Low Power: 25 mW (14 dBm) power.. with -5 dBm/MHz PSD, indoor and outdoor usage. Think of short range use-cases like smartphone to laptop or smartphone to earbuds/ARVR. 2) LPI: already allowed in full 1200 MHz Low Power Indoor: 1W (30 dBm) power with 5 dBm/MHz PSD (clients are 6 dB lower); only indoor usage. Think of your home router. 3) SP: allowed in 850 MHz; no plan to expand AFAIK Standard Power: 4W (36 dBm) power with 23 dBm/MHz PSD (clients are 6 dB lower); indoor or outdoor usage. Requires Aautomated Frequency Coordination; send your location to cloud, cloud tell you which channels area available. Think of enterprise or high power routers; outdoor point to point links (WISP) So, this new regulation is only for VLP and will result in more (especially 320 MHz) channels. No change to the most common usage of Wi-Fi (Router to Laptop/PC).
