802.11ad Packet Formats

What is the general structure of an 802.11ad packet?

An 802.11ad packet consists of a Physical Layer Convergence Protocol (PLCP) preamble, a header, and a MAC Protocol Data Unit (MPDU) payload carrying the actual data.

How does the 802.11ad packet format differ from 802.11a?

802.11ad uses Single Carrier (SC) and OFDM modulations at 60 GHz with specialized preambles for synchronization and beamforming, differing from the OFDM-based 802.11a at 5 GHz.

What are the key fields in the 802.11ad MAC frame?

Key fields include Frame Control, Duration/ID, Address fields (source, destination), Sequence Control, QoS control, and Frame Check Sequence (FCS).

Does 802.11ad support QoS and security in its packet formats?

Yes, 802.11ad packets include QoS control fields and support encryption and authentication protocols similar to other 802.11 standards.

What modulation schemes are used for the payload in 802.11ad packets?

Both Single Carrier and OFDM modulations are used, depending on the rate and conditions, with data rates up to 7 Gbps.

How does 802.11ad handle frame fragmentation?

Similar to other 802.11 standards, 802.11ad supports fragmentation and reassembly to handle large packets efficiently over the wireless medium.

Are control and management frames different in 802.11ad packet formats?

Yes, control frames like ACK, RTS, CTS and management frames like Beacon and Association Request have specific formats but share common header fields.

Where can I find detailed specifications of 802.11ad packet formats?

Detailed format specifications are defined in the IEEE 802.11ad standard document (IEEE 802.11-2012 and amendments).
