The network overview is a quick stop to look through the BSSIDs the device connected to during the test. The 'subnets' can be expanded for each SSID to show some key details for each AP
The Wi-Fi comparison shows some high level statistics which, again, are useful for identifying if the network overall is performing as expected.
The AP with the longest and shortest duration are identified to help understand where most of the time is spent during roaming
The highest and lowest signal APs are show to help discover if an AP is weaker than is should be
The Signal Power Distribution is a histogram which identifies whether the network, on the whole, was within the desired design thresholds for signal power
The secondary power distribution is an estimate of the neighbours power histogram and identifies whether there is healthy secondary coverage - particularly needed for good voice roaming
