Air Interface Parameters
Layer 1 - General
Field Name Values Description
RFS
Active or Passive Specifies whether the RFS has active or passive circuitry.
Gps Offset
0 This is the GPS timing offset to apply to the BTS in order
of chips (2.5us). The GPS offset must be different for
each BTS sharing the same frequency so they do not
interfere with each other.
Sync Scale
0.1125 The scale setting applied to the transmitted
synchronization signal.
Acc Scale
0.0557 The scale setting applied to the Access Channel.
Tcc Scale
0.0197 The scale setting applied to the Traffic Channel.
Max Scale
0.2516 The maximum allowable scale setting for each of the
above scales: Sync, ACC, TCC.
Rx Sensitivity (-
dBm)
100.0 The target Receiver sensitivity for each antenna. This
target is used during full calibration. If it is changed, full
calibration must be performed for it to take effect.
Antenna Power
(dBm)
30.0 The target antenna power for each antenna. This target is
used during full calibration.
Cal Cable Loss (dB)
0.0 Entered in the EMS during commissioning as one of
several inputs for performing full calibration. This value
is the measured calibration cable loss. If it is changed,
full calibration must be performed for it to take effect.
Cal Backplane Loss
(dB)
5.0 Calibration Backplane Loss (dB)
Cal Total Loss (dB)
0.0 Displays the total calibration loss, calculated from the
values in Cal Cable Loss and Cal Backplane Loss fields.
Synthesizer Tx Gain
Displays the Transmitter gain setting for the Synthesizer
used during calibration. This field is a result that is
automatically returned from full calibration.
Synthesizer Rx Gain
Displays the Receiver gain setting for the Synthesizer
used during calibration. This field is a result that is
automatically returned from full calibration.
Synthesizer Sc Gain
Displays the Loopback gain setting for the Synthesizer
used during calibration. This field is a result that is
automatically returned from full calibration.
Synthesizer Level
Displays the power level of the Synthesizer.
