Signal Level
This visualization shows the signal strength map (also called the coverage map) measured in dBm.
Signal strength is one of the most important factors that influence WLAN performance, as in theareas with low signal, establishing a reliable and high-throughput link between the AP and client
devices is impossible.

Signal-to-Noise Ratio
This visualization shows the signal-to-noise ratio (SNR) measured in dB. SNR is a measure to quantify
by how much the signal level exceeds the noise level. Noise is generated by non-802.11 sources ofradio waves (this includes 802.11 frames damaged during propagation). In low SNR zones, client
devices may not be able to communicate with APs.

Signal-to-Interference Ratio
This visualization shows the signal-to-interference ratio (SIR) measured in dB. SIR is a measure toquantify by how much the signal level of an AP (interfered AP) exceeds the interference level. Theinterfering signal is the signal being transmitted by other APs (interfering APs) that may or may notbelong to your WLAN and that use the same or one of the adjacent 802.11 channels. In low SIRzones, client devices may experience low throughput.

AP Coverage Areas
This visualization shows the areas covered by the APs. An area is considered covered if the signal isstrong enough for the clients to communicate to the AP. Coverage areas are color-coded: For eachAP, a small colored square is shown next to the AP icon. The corresponding color is used to display
the coverage area contour or fill.

Number of APs
This visualization shows how many APs cover the given area. An area is considered covered if thesignal 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, andseamless roaming.

Expected PHY Rate
The physical layer (PHY) rate is the speed at which client devices communicate with the AP. Whenyou move a computer connected to the AP within the WLAN coverage area, the adapter properties
dialog in Windows displays the varying connection speed, which may be as high as 450 or 300 Mbps
when you are close to the AP or as low as 1 Mbps when you are 50 meters away from it. The
displayed speed is the PHY rate.

Frame Format
This visualization shows what format of 802.11 frames is being used: Non-HT (a legacy format usedby 802.11 a/b/g equipment that is not based on the latest 802.11n standard), HT-mixed (a newformat introduced in the 802.11n standard that uses a protection mechanism that allows 802.11n
devices to coexist with legacy 802.11 a/b/g devices), or HT-Greenfield (a new format introduced in
the 802.11n standard that assumes that there are no legacy 802.11 a/b/g stations around).

This visualization shows what requirements set by the user are met. The zones where therequirement is not met are marked with the corresponding legend color. If more than one
requirement is not met, only one color will be used.
