802.11ak Packet Formats
What are packet formats in 802.11ak?
Packet formats define the structure of data and management frames used for communication and control.
How does 802.11ak extend traditional 802.11 packet formats?
It introduces new fields and subfields to support precise timing, scheduling, and multi-link operation.
Are new frame types introduced in 802.11ak packet formats?
Yes, 802.11ak adds specialized action frames for scheduling, resource allocation, and link management.
What is the role of the multi-link element in 802.11ak packets?
It carries information about multiple links and their scheduling parameters within a single frame.
How are timing and synchronization details encoded in packets?
Through dedicated TLV (Type-Length-Value) fields in management and action frames.
Does 802.11ak maintain backward compatibility in packet formats?
Yes, it preserves legacy fields while extending formats to support new capabilities.
What frame categories are enhanced by 802.11ak?
Management frames, control frames, and action frames receive extensions for new features.
How are scheduled service periods represented in packet formats?
Specific elements indicate start times, durations, and conditions for scheduled transmissions.
What are the key TLV fields introduced in 802.11ak packets?
Fields for timing synchronization, multi-link info, resource assignment, and link quality metrics.
How does 802.11ak packet format support multi-link operation?
By embedding link-specific identifiers and parameters to coordinate concurrent transmissions.
Are QoS parameters included in 802.11ak packet formats?
Yes, enhanced QoS elements help prioritize time-sensitive traffic within scheduled windows.
How does 802.11ak handle error detection in packets?
Standard CRC and checksum methods are maintained, ensuring data integrity.
Do packet formats specify power-saving information?
Yes, power management fields indicate scheduled sleep and wake times.
How are link measurement results carried in 802.11ak packets?
Measurement reports are formatted with TLVs describing signal strength, noise, and errors.
Are there size constraints for 802.11ak packets?
Packet sizes remain within legacy limits but can include extended information via optional fields.
How does 802.11ak handle packet fragmentation?
Fragmentation and reassembly follow standard 802.11 rules, ensuring compatibility.
Can 802.11ak packets be encrypted?
Yes, security protocols like WPA3 operate over the extended packet formats.
Where can detailed 802.11ak packet format specifications be found?
In the IEEE 802.11ak amendment document and related technical resources.
How do 802.11ak packet formats improve Wi-Fi determinism?
By embedding scheduling and timing info directly into frames, enabling predictable transmissions.
