When the airFiber AF-5 operates in a DFS country, it
performs a Channel Availability Check (CAC) before
operating. The rules vary by country and frequency, but in
general:
•
FCC domains
If the airFiber AF-5 operates in the DFS
band (5.4 GHz band), then the following rule applies:
• If the
TX
and
RX Frequencies
are the same, then the
airFiber AF-5 performs a 60-second check on the
Master
only.
• If the
TX
and
RX Frequencies
are different, then the
airFiber AF-5 performs a 60-second check on both the
Master
and
Slave
.
•
ETSI domains
For most frequencies, the airFiber AF-5
performs a 60-second check on the
Master
and
Slave
;
however, if it operates in the 5600-5650 MHz range, then
the airFiber AF-5 performs a 10-minute check.
While the airFiber AF-5 is performing this check, the
RF
Link Status
displays
DFS CAC
, and the
RF Link Timeout
is
displayed.
If radar is detected, the
RF Link Status
displays
RADAR
Detected
, and the
RF Link Timeout
is displayed.
RF Link Timeout
(Available only if the
RF Link Status
is
DFS CAC
or
RADAR Detected
.) During the
DFS CAC
or
RADAR
Detected
state, the
RF Link Timeout
counts down the time
remaining before the airFiber AF-5 can move to the next
RF link state.
Link Name
Displays the name of your link.
Security
AES-128 is enabled at all times.
Version
Displays the airFiber Configuration Interface
software version.
Uptime
This is the total time the device has been running
since the latest reboot (when the device was powered up)
or software upgrade. The time is displayed in days, hours,
minutes, and seconds.
Link Uptime
This is the total time the airFiber link has
been continuously operational. The time is displayed in
days, hours, minutes, and seconds.
Remote MAC
Displays the Management Ethernet MAC
address of the remote airFiber AF-5.
Remote IP
Displays the Management Ethernet IP address
of the remote airFiber AF-5.
Date
Displays the current system date and time. The
date and time are displayed in YEAR-MONTH-DAY
HOURS:MINUTES:SECONDS format. The system date and
time is retrieved from the Internet using NTP (Network
Time Protocol). The NTP Client is enabled by default on
the
Services
tab. The airFiber AF-5 doesn’t have an internal
clock, and the date and time may be inaccurate if the
NTP Client is disabled or the device isn’t connected to the
Internet.
Duplex
Displays
Full Duplex
or
Half Duplex
. Full-duplex
mode allows communication in both directions
simultaneously. Half-duplex mode allows communication
in one direction at a time, alternating between
transmission and reception.
TX Frequency
Displays the current transmit frequency.
The airFiber AF-5 uses the radio frequency specified to
transmit data.
RX Frequency
Displays the current receive frequency.
The airFiber AF-5 uses the radio frequency specified to
receive data.
Channel Width
Size of the channel in MHz.
Regulatory Domain
Displays the regulatory domain
(
FCC/IC
,
ETSI
, or
Other
), as determined by country
selection.
MGMT MAC
Displays the MAC address of the
Management
port.
MGMT
Displays the speed and duplex of the
Management
port.
DATA
Displays the speed and duplex of the
Data
port.
Chain 0/1 Signal Strength
Displays the absolute power
level (in dBm) of the received signal for each chain.
The software calculates the proper signal strength based
on the measured distance and power levels, and then it
scales the
Signal Strength
bar graphs so that when the link
is aimed correctly, the bar graphs are full-scale. If the bar
graphs are not full-scale, then they indicate that your link
is not optimally aimed.
Remote Chain 0/1 Signal Strength
Displays the absolute
power level (in dBm) of the received signal for each chain
of the remote airFiber AF-5. The bar graphs will display as
full-scale once the link is aimed correctly.
Local Modulation Rate
Displays the modulation rate:
• 10x (1024QAM MIMO)
• 8x (256QAM MIMO)
• 6x (64QAM MIMO)
• 4x (16QAM MIMO)
• 2x (QPSK MIMO)
• 1x (½ Rate QPSK xRT)
• ¼x (¼ Rate QPSK xRT)
If
Automatic Rate Adaptation
is enabled on the
Wireless
tab, then
Local Modulation Rate
displays the current speed
in use and depends on the
Maximum Modulation Rate
specified on the
Wireless
tab and current link conditions.
