Expert Series Webcast: 802.11 Frames: An In-Depth Overview Webcast
August 26, 2014
I cover a number of advanced topics on the 802.11 protocol and walk you through the different types of 802.11 frames and their purpose. I show how a packet turns into a frame; how that frame turns into bits; and, lastly, how the bits get modulated into the air.
You have heard that Wi-Fi is half duplex, right? Let's tackle the complex discussion of CSMA-CA and break down Layer 1 Carrier Sense and Layer 2 Network Allocation Vector, explaining how both work in concert to make sure of a lower probability that two or more stations will not transmit at the same time. I also give a status of my All Wi-Fi office (AWO) with Cisco 3700 802.11ac access points.
You just deployed Cisco 802.11ac access points, and you want to sniff frames? No problem. I share my real-world experience sniffing 802.11ac frames with Wildpacket OmniPeek directly from Cisco 3700s.
If you design, deploy, or manage a Wi-Fi network, do not miss this session.
