Description: This video is a part of IEEE 802.11 (Wi-Fi) basics tutorial video series. IEEE 802.11 is a wireless extension for the MAC layer of OSI model. The basic function of the access point is to translate the wired frames to wireless frames and vice versa. Wired medium was confined to the machines physically present on that subnet only, but due to the very nature of the wireless packets Media Access Control (MAC) layer should be capable of avoiding collisions and it should provide the security. This video explains different field of IEEE 802.11 MAC layer in detail. It explains the Frame Control word and its sub fields like versions, type, subtype, protected field etc and their usage. The wireless addresses and their sequence is the most confusing part of the wireless MAC packet. This video explains lucidly the importance of the sequence and correlation between to-ds and from-ds fields and the MAC address and logic behind it.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>
