Attribute
Meaning
Channel Width
Width (MHz) of the radio channel used by this link. The selection
depends upon the frequency variant and country of operation.
This can only be updated at the Master unit.
Channel Selection
The channel (MHz) in which this link operates. This can only be
updated at the Master unit.
If Channel Width is set to 40 MHz, then each tick box selects two
20 MHz channels: the first is Current Channel and the second is
Extended Channel.
If the system designer has provided a list of channels that may
interfere with TDWR radars, ensure they are unselected.
Antenna Gain
Gain (dBi) of the antenna that is connected to this unit. See
FCC
and IC approved antennas
on page
2-30
.
Cable Loss
Loss (dB) in the RF cable between the ODU and the antenna.
If there is a significant difference in length of the antenna
cables for the two antenna ports, then enter the average
value.
Maximum Power
Level
The maximum power (dBm) at which the unit will transmit.
The highest value in the list is automatically constrained to be
within regulatory limts, based on the values entered in
Antenna Gain and Cable Loss.
Use Fixed Rate
Modulation
If this option is selected, then adaptive modulation is disabled:
the unit transmits data on the selected Modulation Mode only.
If this option is not selected, then adaptive modulation is enabled:
the unit transmits data on the best possible Modulation Mode, up
to and including the selected one. This means that the modulation
mode used is 'capped' at rate shown in the Modulation Mode
attribute.
Modulation Mode
When ‘Use Fixed Rate Modulation’ is selected, this control sets
the modulation mode to use.
When adaptive modulation is selected, this control sets the
maximum modulation mode used by the system.
Enable Dual
Payload
This controls whether the link takes advantage of the channel
condition to increase the link throughput. If not selected, the
robustness of the link is improved.
