The following applies to the AF-5X only:
When the AF-5X operates in a DFS country and within a
valid DFS band for that 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 a DFS band
(5.2 GHz or 5.4 GHz band), the AF‑5X performs a
60-second check on the
Master only.
-
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 AirFiber X radio 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 X radio.
Remote IP
Displays the Management Ethernet IP address
of the remote airFiber X radio.
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 X radio 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
(Available if split frequencies are not enabled.)
Displays the current frequency. The AirFiber X radio uses
the radio frequency specified to transmit and receive data.
TX Frequency
(Available if split frequencies are enabled.)
Displays the frequency that the airFiber X radio uses to
transmit data.
RX Frequency
(Available if split frequencies are enabled.)
Displays the frequency that the airFiber X radio uses to
receive data.
Channel Width
Size of the channel in MHz.
Frame Length
Displays the currently configured frame
length of the radio:
2.0ms
,
2.5ms
,
4.0ms
, or
5ms
. Longer
frame lengths result in higher throughput for a given
configuration, but also result in slightly higher latency.
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 (Actual/Ideal)
Displays the actual and ideal
power levels (in dBm) of the received signal for each chain.
The actual number indicates the current RX signal
strength. The ideal number is the RX signal strength of a
perfectly aligned link. These two numbers indicate exactly
how many dB out of alignment the system is.
When the link is aimed correctly, the bar graphs are full-
scale. If the bar graphs are not full-scale, they indicate that
your link is not optimally aimed.
Rem Chain 0/1 (Actual/Ideal)
Displays the actual and
ideal power levels (in dBm) of the received signal for each
chain of the remote airFiber X radio. 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 airFiber X radio:
• 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 airFiber X radio can send, after accounting for
the modulation and error rates.
