This visualization shows the signal strength map (also called
measured in dBm. Signal strength is one of the most important
factors that influence WLAN performance, as in the areas with low
signal, establishing a reliable and high-throughput link between
the AP and client devices is impossible. Signal level is shown for
the AP that has the strongest signal in the given map area among
the APs selected for analysis. You can deselect one or several of
the selected APs to see the signal level of less strong
A signal level above -60 dBm is considered excellent. Levels
between -60 and -85 dBm are mediocre, and levels below -85 dBm
provide only marginal connectivity. Signal strength is affected by
the distance from the AP, AP output power, type and direction of
antenna, and, most importantly, physical obstructions, such as
walls, doors, windows, and their material.
Double-clicking on the signal level legend on the status bar allows
you to configure the color scheme and change its value
When low signal areas are discovered, the following solutions are
Change AP locations: You should minimize the number of obstructions
between the AP and the low signal zone. Additionally, the material
of the obstructions plays an important role; for example, the
attenuation factor of a brick wall far exceeds that of a cubicle
wall or window.
Add more APs: Sometimes repositioning APs does not provide the
desired effect, and the option becomes installing additional APs in
the problematic areas.
Use a different antenna: A high-gain antenna (if your AP supports
the use of such antennae) redirects radio signal in the desired
direction, thereby increasing the signal level in some zones and
decreasing it in the others.
Increase output power: Some APs allow for the adjustment of the
transmission power. However, for most, the maximum power is already
set as the default factory setting.
