802.11v PHYs
Does 802.11v define a new PHY layer?
No — 802.11v is primarily a Wireless Network Management amendment built on existing PHY layers. :contentReference[oaicite:0]{index=0}
Which PHYs are compatible with 802.11v?
All standard IEEE 802.11 PHYs (a, b, g, n, ac, ax, etc.) can be used with 802.11v features. :contentReference[oaicite:1]{index=1}
How does 802.11v interact with radio measurements at PHY?
802.11v extends radio measurement capabilities, allowing the MAC/management layers to request PHY‑level metrics (e.g. channel load, signal strength). :contentReference[oaicite:2]{index=2}
Do 802.11v features change modulation or coding schemes?
No, 802.11v does not alter modulation or coding schemes — those remain governed by the PHY standard in use.
Can 802.11v affect how the PHY chooses data rates?
Indirectly — by providing better network context (via management/measurement), it may help devices choose better APs or channels, which influences achievable PHY rates.
Is PHY header format changed by 802.11v?
No, the PHY header and preamble formats remain as defined by the base PHY; 802.11v does not modify PHY framing.
Do 802.11v measurement frames require special PHY timing?
Measurements must respect PHY timing constraints (e.g. sample durations), but 802.11v does not add new timing rules at the PHY level.
How does 802.11v support channel load reporting at PHY?
Clients or APs report metrics (e.g. busy time, interference) based on PHY observations, conveyed via 802.11v management frames.
Does 802.11v support new frequency bands via PHY?
No — 802.11v works with whatever bands the underlying PHY supports (e.g. 2.4 GHz, 5 GHz, 6 GHz).
Can 802.11v be used over 6 GHz (Wi-Fi 6E) PHYs?
Yes, provided the device’s PHY supports 6 GHz, 802.11v functionality should be transparent over it.
Does 802.11v require PHY changes to support measurements?
No hardware-level changes are required; it leverages existing PHY measurement capabilities.
How are PHY metrics integrated in 802.11v decision processes?
PHY metrics like RSSI, signal-to-noise ratio, channel utilization are sent in measurement reports for higher-layer management decisions.
Are PHY error metrics (e.g. bit error rate) reportable via 802.11v?
Potentially, yes — if the device tracks such metrics, 802.11v can carry them in measurement reports.
Does 802.11v influence PHY’s channel scanning behavior?
It may guide the scanning schedule or selection via management hints, but scanning methods are still PHY-driven.
Can 802.11v help with PHY-based interference mitigation?
Indirectly — by reporting channel conditions and facilitating client transitions away from interfered channels.
Does 802.11v add new PHY fields in the payload?
No — 802.11v keeps PHY payload structures intact; all 802.11v data is in the MAC/management portion.
Is there any PHY‑level overhead introduced by 802.11v?
Only minimal, due to slightly larger management frames, but PHY framing overhead remains unchanged.
How is PHY link quality used in 802.11v transitions?
Link quality measurements from PHY inform BSS Transition decisions via 802.11v IEs.
Does 802.11v affect PHY’s rate fallback behavior?
No — fallback logic is local to PHY/MAC rate control; 802.11v only assists in network-level decisions.
Where is 802.11v’s PHY support defined officially?
In the IEEE 802.11v-2011 amendment documentation, which extends both MAC and PHY for Wireless Network Management. :contentReference[oaicite:3]{index=3}
