TR-WMX-3.5 Betriebsanleitung für Teilnehmergeräte
Parameter
Choose This Setting
CP Size
Sets the cyclic prefix size, which helps mitigate multipath-
induced signal degradation. Choices are 1/4, 1/8, 1/16
(
default
), or 1/32. This setting should match the CP setting of
the base station to which the device is connecting.
Secondary Management Connection Support
Confirm that the default setting (Secondary Management
Support) is selected. If not, select it.
Initial Ranging Burst Inverting
Confirm that the default setting (Software Auto) is selected. If
not, select it.
Adaptive Modulation (DBPC)
Confirm that the default setting (Auto using CINR thresholds)
is selected. If not, select it.
Frequency (KHz)
Sets the frequency, in kHz. Range is 3400000 – 3600000 in
increments of 250. Default is 3450000 (3.45 GHz).
Initial Delay Correction Value
Confirm that the default setting (0) is selected. If not, select it.
Max TX Power (dBm)
This value should match the TR-WMX-3.5 antenna.
Examples:
•
TR-WMX-3.5-14: specify a value that is 14db less than
the max EIRP setting. If the max EIRP setting is 30dBm,
for example, set Max Tx Power to 16dBm.
•
TR-WMX-3.5-17: specify a value that is 17db less than
the max EIRP setting. If the max EIRP setting is 30dBm,
for example, set Max Tx Power to 13dBm.
•
TR-WMX-3.5-20: specify a value that is 20db less than
the max EIRP setting. If the max EIRP setting is 30dBm,
for example, set Max Tx Power to 10dBm.
The Max Tx Power value cannot exceed 20dBm. Default
setting is 20.
Note: When setting the Max Tx Power value, do not exceed
the max EIRP allowed by your license. When adding the
values for Tx Antenna Gain and Max Tx Power, the sum of
these values must equal or be less than the max EIRP that
your license allows. The gain of the internal antenna is 17dB,
requiring the Max Tx Power to be set to (max EIRP – 17).
Min Tx Power (dBm)
Confirm that the default setting (-10) is selected. If not, select
it.
Rx Antenna Gain (1/4dB step)
Confirm that the default setting (0) is selected. If not, select it.
Tx Antenna Gain (1/4dB step)
Confirm that the default setting (0) is selected. If not, select it.

Parameters in Figure 1-10
MAC Message Strict Checking
Confirm that the default setting (Disable) is selected. If not,
select it.
Pack Enable for Primary CID
Confirm that the default setting (Enable) is selected. If not,
select it.
Fragment Enable for Primary CID
Confirm that the default setting (Enable) is selected. If not,
select it.
Tx Overrun Fix
Confirm that the default setting (Disable) is selected. If not,
select it.
