Summary: <br> 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.<br> 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.<br> Data Frames<br> <br> * Data<br> * Data + CF-Ack<br> * Data + CF-Poll<br> * Data + CF-Ack + CF-Poll<br> * Null<br> * CF-Ack (no data)<br> * CF-Poll (no data)<br> * CF-Ack + CF-Poll<br> * QoS Data<br> * QoS Data + CF-Ack<br> * QoS Data + CF-Poll<br> * QoS Data + CF-Ack + CF-Poll<br> * QoS Null (no data)<br> * QoS CF-Poll (no data)<br> * QoS CF-Ack + CF-Poll (no data)<br> <br> 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).<br> This Week In Wireless<br> CWAP-402 will launches June 28th, 2016 replacing the current PW0-270. Last day to take PW0-270 is June 27th, 2016. Study guide will be available end of May 2016. You can register for the webinar outlining whats new in the CWAP exam which occurs on <a href="https://www.cwnp.com/freeresources/it-webinars/" title="CWNP Webinars">April 21st</a><br>
