Number of APs

This visualization shows how many APs cover the given area.  An area is considered covered if the signal is strong enough for the clients to communicate with the AP. In many WLANs, multiple AP coverage is an important requirement that ensures uninterrupted connectivity, load balancing, and seamless roaming. If this requirement exists in your WLAN, you can use this visualization to make sure that AP coverage areas sufficiently overlap.

As in the AP Coverage Areas visualization, the definition of “strong enough” is rather subjective because certain signal strength might be sufficient for low data rates, but insufficient for the high data rates required for such applications as VoIP. Additionally, 802.11 adapters vary in sensitivity, and some adapters might be able to provide good connectivity in zones where other adapters fail to connect altogether. The Visualization Settings panel (located on the Options tab of the right-side panel) offers the Area is considered covered if signal strength is at least setting, which defines the AP coverage area based on the minimum signal strength. If the signal strength is below the specified level, the area is considered to be not covered.

Double-clicking on the Number of APs legend on the status bar allows you to configure the color scheme.
