The wrap up of a three part series on wireless frames. In previous episodes, I discussed Management and Control frames. Within those episodes I mentioned the frame subtypes contained in each of those frames.

This episode is about Data frames and the data frame subtypes. There are fifteen data frame subtypes which I will briefly go over in the podcast episode.

Data Frames

* Data

* Data + CF-Ack

* Data + CF-Poll

* Data + CF-Ack + CF-Poll

* Null

* CF-Ack (no data)

* CF-Poll (no data)

* CF-Ack + CF-Poll

* QoS Data

* QoS Data + CF-Ack

* QoS Data + CF-Poll

* QoS Data + CF-Ack + CF-Poll

* QoS Null (no data)

* QoS CF-Poll (no data)

* QoS CF-Ack + CF-Poll (no data)

The data frame image above highlights the frame type, shown as data, the subtype as a QoS data frame. The image also shows the additional QoS Control field that is part of the data frame because of the subtype that it is (QoS).
