Some important physical layer values you need to be aware of are channel, data rate, and signal strength. It is important to get an understanding of the physical layer of the capture before diving into the capture to analyze the upper layers. Know the differences between every type of “area network.Unlike wired packet analysis, the wireless physical layer is more complex. Heating, ventilation, and air conditioning
