Scheduling Cycle
: Enter the period of the traffic scheduling cycle.
Important
:
You
MUST
reboot the RDL-3000 after changing this parameter.
As a general guide, a short scheduling cycle provides lower latency and a long
scheduling cycle provides greater efficiency for packet processing. Latency and
efficiency are also affected by other factors (packet rate, packet size, etc).
Fixed Frame
: Enable or disable fixed frame mode. System requires reboot following
changes to this parameter. Fixed frame operation requires GPS to be active and
synchronized. When Fixed Frame mode is disabled, the RDL-3000 operates in variable
frame mode and the GPS signal synchronizes the system DCXO.
Disabled
( ): System automatically adjusts the wireless frame size.
Enabled
( ): Wireless frame size is fixed at operator selection.
Important
:
You
MUST
reboot the RDL-3000 after changing this parameter.
Frame Size [ms]
: (SC only) Valid only when fixed frame mode is enabled. Restricted to
10 ms. System requires reboot following changes to this parameter.
Downlink Ratio [%]
: (SC only) Valid only when fixed frame mode is enabled. Restricted
to 50%. System requires reboot following changes to this parameter.
GPS Antenna Type
: Set the mode of operation for the GPS antenna.
Passive
: The GPS antenna port is configured for a passive type GPS antenna (does
not require a bias voltage).
Active
: The GPS antenna post is configured for an active type GPS antenna (e.g.,
antenna enclosure includes a built-in amplifier). A bias voltage is supplied on the
center conductor of the GPS antenna connector.
Notes:
1.
A system reboot is required to activate changes to this setting when running
software v2.23/2.25 Update 5 or higher.
2. Use the 'Passive' setting for deployments where the sector antennas and systems
include integrated GPS antennas.
i) Sector antenna with integrated GPS antenna (check antenna datasheet).
ii) RAS-Elite series nomadic platform (integrated GPS antenna).
2. Use the 'Active' setting for deployments where a stand-alone GPS antenna kit is
used (e.g., 3K-GPS-ANT):
i) All Redline UHF sector antennas.
ii) Sector antennas that do not include integrated GPS (check antenna datasheet).
iii) Redline RAS B-100 series nomadic platform.
Antenna Alignment Buzzer Enable
: (SS only) Audible antenna alignment tool.
Disabled
( ): The antenna alignment tool is disabled (no sound).
Enabled
( ): The antenna alignment tool is active. Faster repetition rates of the
sound indicate a stronger signal is being received from the remote-end transmitter.
Cyclic Prefix
: Select the cyclic prefix size (1/4 or 1/8) for this sector. This setting must
match on the sector controller and all subscribers in the sector. Refer to the following
tables. You
MUST
reboot the RDL-3000 after changing this parameter
Important
: Cyclic prefix 1/8 is recommended for use only with 10 and 20 MHz channels.
Radio Mode
: Select the operational mode for the RF transmitters.
