Abstract: In an example, a wireless client station detects a first signal emitted by a first wireless access point and a second signal emitted by a second wireless access point. The wireless client station extracts a first set of data indicative of the signal strength and network congestion of the first wireless access point and a second set of data indicative of the signal strength and network congestion of the second wireless access point.
