List of PPDUs Supported in 802.11v
Does 802.11v define new PPDU formats?
No, 802.11v uses existing PPDU formats defined by the underlying PHY standard (e.g., 802.11n/ac/ax).
What is a PPDU in 802.11 networks?
A PPDU is the unit of data transmitted over the physical medium, including preamble, header, and payload.
Does 802.11v require changes to PHY headers or modulation?
No, it does not change modulation schemes or physical headers.
How are 802.11v management frames transmitted?
They are encapsulated in standard MAC frames, which are then sent using the regular PPDU format.
Do 802.11v features affect preamble structure?
No, preamble structure remains defined by the underlying PHY layer and is unaffected by 802.11v.
What PHY layers are compatible with 802.11v PPDU use?
All standardized PHYs (a/b/g/n/ac/ax) support 802.11v without PPDU modification.
Is a new preamble used for 802.11v functions?
No, the same preambles used by the PHY standard are used for 802.11v frames.
Are 802.11v messages encrypted inside PPDUs?
If encryption is enabled at the MAC layer (e.g., WPA2/3), the payload within the PPDU can be encrypted.
Can 802.11v use both 2.4 GHz and 5 GHz PPDU formats?
Yes, 802.11v operates over any band supported by the PHY, using the respective PPDU format.
Is there a PPDU distinction between 802.11v and legacy traffic?
No, all traffic—whether related to 802.11v or not—uses the same PPDU formats.
Does 802.11v affect the duration field in PPDUs?
No, duration and other physical-level parameters are governed by the PHY and MAC framing.
Can 802.11v PPDU payloads carry control information?
Yes, MAC-layer control frames (e.g., BSS Transition Management) are encapsulated in standard PPDUs.
How does 802.11v coexist with legacy PPDU devices?
Seamlessly, because no changes are made to PPDU formats or PHY-layer signaling.
Are beamforming and MU-MIMO affected by 802.11v?
No, these are PHY features unaffected by 802.11v, though better AP selection may improve performance.
Can 802.11v frames be prioritized at the PPDU level?
Prioritization happens at the MAC layer using QoS; the PPDU just carries the result.
How does the 802.11v feature BSS Transition use PPDUs?
The transition management frames are encapsulated in MAC frames, transmitted via standard PPDUs.
Are 802.11v messages affected by channel bandwidth at the PPDU level?
Only in terms of PHY capabilities; 802.11v messages follow the rules of the chosen bandwidth.
Do 802.11v-enabled devices need PHY changes to handle PPDUs?
No, they use existing PHY implementations without any modification.
Does 802.11v use any special signaling at the PPDU level?
No, all signaling for 802.11v occurs at MAC and management frame levels.
Why doesn’t 802.11v require new PPDU types?
Because it’s a MAC layer enhancement—it relies on existing physical infrastructure and formats.
