Wide Channel Contention

How does Wi-Fi contention work when the channel width is greater than 20 MHz? We encounter AP’s operating with wide channels all the time, so it’s important to know what contention looks like on those channels. Jim Vajda, CWNE #183, will introduce you to all the differences in channel access across the PHY’s and across different channel widths. 

Topics we'll cover:

• Everyday 20 MHz EDCA
• 802.11n 40 MHz channel access
• 802.11ac 40/80/160 MHz channel access
• 802.11ax 40/80/160 MHz channel access
• Implications for design
