Very useful for testing Ghz bands

Our router works in both the 2.4 Ghz and 5Ghz ranges. With over 200 units in our building, the 2.4 Ghz range essentially gets crowded and has interference (Ive forgotten the technical name for it) causing the effective Mbps rate to slow. With Speedtest, Ive verified that the 5Ghz band is effectively twice as fast as the 2.4.
