Description: This is the last part of the Wi-Fi MAC header videos. It talks about the sequence control field, packet body and the Frame Check Sum (FCS) present in the packet. IEEE 802.11 standard divides the frames in to 3 types viz. Management frames, Control frames and Data frames. Every type has its own subtypes e.g. management frames has subtypes like beacon, probe request, probe response, action management frames etc. or control subtypes are like RTS, CTS, ack etc. This video explains different types and subtypes, how to apply simple filter in wireshark for separating these types and subtype and at the end demonstrates a wireless packet in wireshark with different MAC headers. This video series is a tutorial for IEEE 802.11 protocol suite, commonly knows as Wi-Fi. In this video series, you will find videos explaining the basic 802.11 standard and their other amendments like 802.11a, 802.11g, 80211h, 802.11i, 802.11w, 802.11n, 802.11e etc. There are videos dedicated to security in wifi protocols, the different packets and state machine of 802.11 protocol and many more such things. We have tried to make this video series more interactive than just informative. You will find lots of discussions over the issues in 802.11 and justification for many small features in 802.11. Feel free to pose your own problems in the comment section and we will try to capture them in next videos. This section is currently under construction, so keep watching for new content.Links <p> 1. <span class="SpellE">Wi-Fi alliance Home Page</p> <p> 2. IEEE 802.11 wiki page </p>
