Ubiquiti Networks, Inc.
When the AF-5X 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 AF-5X 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
AF-5X performs a 60-second check on the Master only.
• If the TX and RX Frequencies are different, then the
AF-5X performs a 60-second check on both the Master
and Slave.
• ETSI domains For most frequencies, the AF-5X
performs a 60-second check on the Master and Slave;
however, if it operates in the 5600-5650 MHz range, then
the AF-5X performs a 10-minute check.
While the AF-5X 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 AF-5X 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 AF-5X.
Remote IP Displays the Management Ethernet IP address
of the remote AF-5X.
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 AF-5X 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.
Frequency Displays the current frequency. The AF-5X
uses the radio frequency specified to transmit and
receive data.
Channel Width Size of the channel in MHz.
Duty Cycle Displays the duty cycle.
Regulatory Domain Displays the regulatory domain
(FCC/IC, ETSI, or Other), as determined by country
selection.
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 AF-5X. The bar graphs will display as full-
scale once the link is aimed correctly.
Local Modulation Rate Displays the modulation rate:
• 8x (256QAM MIMO)
• 6x (64QAM MIMO)
• 4x (16QAM MIMO)
• 2x (QPSK MIMO)
• 1x (½ Rate QPSK xRT
™ *)
• ¼x (¼ Rate QPSK xRT)
*xtreme Range Technology
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.
Remote Modulation Rate Displays the modulation rate
of the remote AF-5X:
• 8x (256QAM MIMO)
• 6x (64QAM MIMO)
• 4x (16QAM MIMO)
• 2x (QPSK MIMO)
• 1x (½ Rate QPSK xRT)
• ¼x (¼ Rate QPSK xRT)
TX Capacity Displays the potential TX throughput,
how much the AF-5X can send, after accounting for the
modulation and error rates.
RX Capacity Displays the potential RX throughput, how
much the AF-5X can receive, after accounting for the
modulation and error rates.
TX Power (EIRP) Displays the current average transmit
output power (in dBm) of the AF-5X.
Note: If “(Limited)” is displayed, then the transmit
output power has been limited to a value less than
the selected value, to comply with regulatory region
requirements. For a list of maximum output power
values by country and region, refer to “Frequency
Ranges and Power Levels per Country/Region” on
page 41.
