802.11aq Physical Rates

What are the supported physical data rates in IEEE 802.11aq?

802.11aq supports multiple physical data rates inherited from underlying 802.11 standards like 802.11ax, including rates from a few Mbps up to several Gbps depending on band and channel width.

How does 802.11aq determine which physical rate to use?

Rate adaptation algorithms dynamically select the optimal physical rate based on signal quality and channel conditions.

Does 802.11aq support OFDMA for physical rate improvement?

Yes, 802.11aq leverages OFDMA from 802.11ax to improve efficiency and physical layer throughput.

What modulation schemes are used to achieve different physical rates in 802.11aq?

Modulation schemes include BPSK, QPSK, 16-QAM, 64-QAM, 256-QAM, and up to 1024-QAM depending on the PHY version.

How does channel bandwidth affect physical rates in 802.11aq?

Wider channels (e.g., 40 MHz, 80 MHz, 160 MHz) enable higher physical rates due to increased data capacity.

Are physical rates fixed or adaptive in 802.11aq?

They are adaptive; the device selects the best rate to balance speed and reliability.

How is physical rate information conveyed in 802.11aq packets?

Rate information is specified in the SIGNAL field of the PHY header.

Can 802.11aq devices operate at legacy rates?

Yes, to maintain backward compatibility with older devices.

What role do coding rates play in physical rate determination?

Coding rates (e.g., 1/2, 3/4) affect error correction and thus the effective physical data rate.

Does 802.11aq support MIMO to increase physical rates?

Yes, multiple-input multiple-output (MIMO) techniques are used to boost data throughput.

How do environmental factors influence physical rates in 802.11aq?

Signal interference, distance, and obstacles can reduce the achievable physical rate.

Are physical rates symmetrical for transmit and receive in 802.11aq?

Not necessarily; transmit and receive rates can differ based on channel conditions.

What is the maximum physical rate achievable with 802.11aq?

Depending on the PHY version (e.g., 802.11ax), rates can reach several Gbps with the highest modulation and channel width.

How does 802.11aq handle physical rate selection during handoff?

The device re-evaluates link quality and may adjust rates to maintain optimal throughput.

Is rate adaptation standardized in 802.11aq?

Rate adaptation mechanisms follow underlying 802.11 PHY standards, but 802.11aq does not mandate a specific algorithm.

How does power control relate to physical rates in 802.11aq?

Adjusting transmit power helps maintain link quality, indirectly influencing achievable rates.

Do physical rates affect battery consumption in 802.11aq devices?

Higher physical rates can reduce transmission time and thus save battery, but require better signal conditions.

Can 802.11aq physical rates be manually configured?

Typically no; devices use automatic rate adaptation for best performance.
