How a Single Frame Gets Transmitted on the RF Medium

Since Wi-Fi is invisible, many think of it as Ethernet without the wires. In reality, there is a LOT of complexity in order for a single frame to be transmitted over the Radio Frequency medium. In this episode with special guest Keith Parsons, we'll discuss the various amounts of overhead and why this is useful in Wireless LAN communications.

Topics include:

- Single data frame exchange.

- The limitations of 802.11.

- The Wireless to Wired boundary.

- Real use cases. 

Wi-Fi Channel Utilization 101

Organizations spend millions of dollars on their wireless networks, but very few people understand how they really work. Understanding Wi-Fi channel utilization will help you troubleshoot and diagnose wireless issues faster. 

On this episode, we'll put you in the know by covering:

- Basics of Wi-Fi channels

- Co-channel interference 

- Channel planning 

- Channel utilization 

- Real use cases

- And more!
