Wi-Fi in Slow Motion: The Nanosecond Timeline | PRG 26

We talk about Wi-Fi in terms such as RSSI and Mbps. But what's actually happening when you stream a video, download a file or send an email?

Let's take a look inside that second of communication between your client and the AP. This talk takes a single second of 802.11 activity from an AP, a couple of clients and a noisy neighbour network on an overlapping channel, and dissects it.

We’ll look at what happens in a second, and zoom in through milliseconds, microseconds and nanoseconds to understand the intricacies of this wonderful technology. Expect all sorts of Inter Frame Spacings, A-MPDU aggregations and OFDM symbols!
