Transmitting a Single Frame Across the RF Medium from Keith R. Parsons

In his Ignite Talk, Keith R. Parsons delves into the intricate process of transmitting a single frame of data across a wireless access point, emphasizing the significant overhead involved. He explains that while factors like channel width and modulation coding schemes (MCS) can affect the payload portion of the transmission, the majority of the process is dominated by protocol overhead, including arbitration time, preambles, and control frames like RTS and CTS. Parsons highlights that even with advancements such as wider channels in Wi-Fi 7, the overall transmission time for a single frame remains largely unchanged because the overhead components stay constant. He encourages the audience to use tools like Garamond’s calculator to visualize these dynamics and understand that improvements in data rates primarily impact the payload, not the total transmission time.
