We also show variations over time for both RSSI (middle) and throughput (bottom). The labeled numbers correspond to the location waypoints on top. Notice that RSSI tends to dip suddenly during a handoff. The best performing algorithms immediately switch to another AP with higher RSSI. In contrast, notice that aggressive disassociations experiences two lengthy periods without connectivity that we see corresponds to RSSI lingering at levels of low RSSI. This is a result of poor AP selection from noisy scans.
