A MAC address is a hardware address that uniquely identifies each node of
a network.
• Idle —The amount of time this WLAN client has remained inactive.
A WLAN client is considered to be inactive when it is not receiving or
transmitting data.
• Rate —The negotiated data rate. Actual transfer rates can vary depending on
overhead.
The data transmission rate is measured in megabits per second (Mbps). The
value should fall within the range of the advertised rate set for the mode in
use on the access point. For example, 6 to 54 Mbps for 802.11a.
The reported rate is the speed of the last packet transmitted from the AP to
the client. This value can vary within the advertised rate set based on the
signal quality between the AP and client and the rate at which broadcast or
multicast frames are sent. When the AP sends a broadcast frame to a STA
using the default rates, then the field will report 1 Mbit/sec for 2.4Ghz radios
and 6 Mbit/sec for 5 GHz radios. Clients that are idle are most likely to report
the low default rates.
• Signal —The strength of the radio frequency (RF) signal the WLAN client
receives from the access point. The measure is known as Received Signal
Strength Indication (RSSI), and is a value between 0 and 100.
• Receive Total —The number of total packets received by the WLAN client
during the current session.
• Transmit Total —The number of total packets transmitted to the WLAN client
during this session.
• Error Rate —The percentage of time frames are dropped during
transmission on this access point.
