2.3.1 General Parameters
Radio Band (GHz) A read-only display of the radio band of the unit.
Current Operating
Frequency (MHz)
A read-only display of the current operating frequency of the device.
For details on setting frequenies, refer to the Air Interface Frequency
page.
Maximum Number Of
Associations Limit
Applicable only for AU. A read-only display of the maximum number
of SUs that can associate with the AU.
For a regular AU, the Maximum Number Of Association Limit is 512
when data encrypyion is disabled and 124 when data encryption is
enabled. For AUS the Maximum Number Of Association Limit is 8.
Maximum Number Of
Associations
Applicable only for AU. The Maximum Number Of Associations
parameter defines the maximum number of SUs that can become
associated with the AU, while still guaranteeing the required quality of
service to customers.
Available values range from 0 to 512 for a regular AU (0 to 124 when
data encryption is enabled), 0 to 8 for AUS.
Note that for a regular AU the Maximum Number Of Associations
must be set to a value of 124 or lower to enable data encryption. As
long as data encryption is enabled, the Maximum Number Of
Associations cannot be set to a value higher than 124.
Antenna Gain (dB) The Antenna Gain parameter enables to define the net gain of a
detached antenna. The configured gain should take into account the
attenuation of the cable connecting the antenna to the unit. The
Antenna Gain is important especially in countries where there is a
limit on the EIRP allowed for the unit; where the maximum allowed
value for the Transmit Power parameters cannot exceed the value of
(EIRP - Antenna Gain). The EIRP is defined in the selected
Sub-Band.
In certain units with an integral antenna the Antenna Gain is not
configurable, and it is available as a read-only display of the net gain
of the inegral antenna.
The range (in dBi) is from 0 to either 50 or Regulation Maximum EIRP
+ 10 (the lowest of the two values). If Regulation Maximum RIRP is
No Limit, than the highest limit is 50). A value of "Don't Care"
(presented as -2) means that the actual value is not important since
there is no limitation on the EIRP in the Country Code being used by
the unit. A value of "Not Set Yet" (presented as -1) means that the unit
will not transmit until the actual value is configured. Once a value is
configured, it is not possible to reconfigure the unit to either "Don't
Care" or "Not Set Yet".
