Chapter 4: Main Tab airFiber ® AF5/AF5U User Guide
Ubiquiti Networks, Inc.
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.
