WLAN Analysis with Wireshark (802.11 Radio Information, Part 3)

Let's continue to get exposure on other sub-fields within 802.11 Radio Information, where we can refer to the below diagram for illustration.

Data Rate: The wireless transmit rate is the speed that data is being transmitted from an AP to a wireless device.
The maximum data rate for 802.11a (5 GHz) is 54 Mbps, 802.11b (2.4 GHz) is 11 Mbps, 802.11g (2.4 GHz), 54 Mbps, and 802.11ac can be up to 1,300 Mbps.

The below diagram is a collection of frames, in 802.11a, where you can see the data rate being displayed include 6, 9, 24 Mbps.

Within the very same Wireshark capture file, we also are able to realize 802.11ac frames, where the date rate stays pretty much the same, 780 Mbps, in the underneath diagram.

Quiz Review:

• For 802.11n connections, what is the maximum wireless transmit rate?
• According to below diagram, the Data Rate is only 1 Mbps, but the Wireshark capture does not have "Phy type" subfield, what would be a possible and smart guess on "Phy type" being utilized?
