DFS Antenna Gain : Enter the gain (dBm) for the system antenna.
It is important that the DFS Antenna Gain matches the actual antenna gain.
If the DFS Antenna Gain is set higher than the true antenna gain, the system is less
sensitive to detecting interference, and is not operating in compliance with the
UK/ETSI standard. If the DFS Antenna Gain is set lower than the true antenna
gain, the system is more sensitive to interference and this may result in false DFS
triggers.
Note: This hardware-enabled feature is not available on the AN-50.
Tx Power [dBm] : (see Max. RF Power [dBm])
ATPC Enable : Check this box to enable the ATPC function. The master-end
system automatically adjusts the Tx level of both the
master unit
and
remote-end unit
to optimize the system performance.
Note: This hardware-enabled feature is not available on the AN-50.
Adaptive Modulation : Check this box to enable adaptive modulation mode.
It is recommended to use adaptive modulation mode when using Ethernet only
traffic. When enabled, the system can automatically change the modulation
scheme to the highest possible order, based on measured RF performance. Adjust
the modulation scheme by setting the Uncoded Burst Rate parameter. If packet
errors exceed one in one million, the system automatically steps down to the
modulation scheme to maintain the wireless link.
PTP mode only.
Modulation Reduction Level : This manual setting specifies how many levels to
drop the modulation during re-transmission of erroneous wireless packets. The
level can be set from 0-7, with 2 being the recommended value. This setting is
valid only when Adaptive Modulation
is disabled.
Uncoded Burst Rate [Mb/s] : Select the desired uncoded burst rate for the link.
Master Mode : Check this box to enable the system to operate as the sector
controller. Each link is comprised of a sector controller and one or more
subscribers. The sector controller establishes and manages the bi-directional data
link with each AN-50e subscriber. The subscriber receives and sends data under
the control of the sector controller.
Important: Only one system in a wireless link must be set for Master mode.
Software Version : Select the version of system software to load at reset. The
system includes memory to hold two independent system software images. See
Upload Software Section 3.7: for additional details.
Encryption Enable : Check this box to enable over-the-air encryption.
If encryption is enabled, no Ethernet packets can be transferred unless encryption
is enabled on both the local and subscriber terminals.
Encryption Key : Enter the MAC address of the subscriber as the over-the-air data
encryption key. No Ethernet packets can be transferred unless the correct
encryption is entered at both the sector controller and subscribers.
Link Length Mode : Select the mode for determining the distance of the wireless
link. See Link Length.
