Table 7-5 System Status Wireless attributes
Attribute Meaning
Link Status Current status of the wireless link. A state of ‘Up’ on a green
background indicates that a point-to-point link is established.
Any status on a yellow background indicates that the wireless
link is not established.
Whenever the Link Status is not ‘Up’, a yellow warning
triangle is displayed on the navigation bar. For more
information, refer to Managing link status and alerts on pag
e
7-15.
MAC Address MAC address of the radio interface of this unit.
Channel Width Width of the wireless channel, either 20 MHz or 40 MHz. This
is set in the Installation Wizard; see Step 2: Wireless
co
nfiguration on page 6-17.
Current Channel The channel (MHz) in which this link operates. This is set in
the Installation Wizard; see Step 2: Wireless configuration on
page 6-17.
Extended Channel The extended channel (MHz). This only applies when Channel
Width is 40 MHz.
Transmit Power The maximum, mean, minimum and latest measurements of
Transmit Power (dBm). See Diagnostics calculated over time
on page 7-23.
Receive Power The maximum, mean, minimum and latest measurements of
Receive Power (dBm). See Diagnostics calculated over time
on page 7-23.
Vector Error The maximum, mean, minimum and latest measurements of
Vector Error (dB). See Diagnostics calculated over time on
page 7-23.
The ve
ctor error measurement compares the In-phase /
Quadrature (IQ) modulation characteristics to an ideal signal
to determine the composite error vector magnitude.
Vector Error is expected to range from -2 dB (NLOS link
operating at sensitivity limit on BPSK 0.50) to –27 dB (short
LOS link running 64QAM 0.83). These are approximate
values.
