During the live event, Wi-Fi subject matter expert George Stefanick will cover a number of advanced topics on the 802.11 protocol. George will walk you through the different types of 802.11 frames and their purpose. He will 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? George will tackle the complex discussion of CSMA-CA. He will 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. He will also give a status of his all Wi-Fi office with Cisco 3700 802.11ac access points.

You just deployed Cisco 802.11ac access points, and you want to sniff frames? No problem. George will share his 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.
