Actual 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. Thedisplayed speed is the actual PHY rate at which the client was connected to the AP during an activesurvey.

TCP Upstream Rate
This visualization shows the TCP upstream throughput measured in Megabits per second. This is theamount of useful information that is delivered per second to the application layer protocol from theclient to the server, i.e., upstream. This value does not include protocol overhead.

TCP Downstream Rate
This visualization shows the TCP downstream throughput measured in Megabits per second. This isthe amount of useful information that is delivered per second to the application layer protocol fromthe server to the client, i.e., downstream. This value does not include protocol overhead.

UDP Upstream Rate
This visualization shows the UDP upstream throughput measured in Megabits per second. This is theamount of useful information that is delivered per second to the application layer protocol from theclient to the server, i.e., upstream. This value does not include protocol overhead.

UDP Downstream Rate
This visualization shows the UDP downstream throughput measured in Megabits per second. This is
the amount of useful information that is delivered per second to the application layer protocol fromthe server to the client, i.e., downstream. This value does not include protocol overhead.

UDP Upstream Loss
This visualization shows the UDP loss that is calculated as the percentage of data that was lost
during transmission from the client to the server, i.e., upstream.

UDP Downstream Loss
This visualization shows the UDP loss that is calculated as the percentage of data that was lost
during transmission from the server to the client, i.e., downstream. In a WLAN, high UDP
downstream loss values are normal, because the server on the wired side can typically send far
more packets per second than the AP can transmit to the client.

Round-trip Time
This visualization shows the round-trip time (RTT) measured in milliseconds. RTT is the length oftime it takes for a data packet to be sent from the client to the server and back.

Associated AP
This visualization shows to which AP the client was associated during an active survey. This makes it
possible to analyze client roaming behavior.

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