Upcoming LIVE Expert Webcast: 802.11 Frames: An In-Depth Overview, with George Stefanick

Please join us on Tuesday, August 26, 2014 at 10 a.m. PDT San Francisco (UTC -7 hours) for this live, interactive event. This corresponds to 1 p.m. EDT New York (UTC -4 hours), 6 p.m. London (BST UTC +1), or 7 p.m. Paris (CEST UTC +2).

During this 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.
