BreezeACCESS 4900 124 System Manual
This feature can be used during maintenance or testing to avoid transmissions
using undesired parameters.
The parameter is available only when managing the unit from its Ethernet port.
The default is On.
4.2.6.2.8 Antenna Gain
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 cases when there is a limit on the EIRP allowed for the unit; the
maximum allowed value for the Transmit Power parameters cannot exceed the
value of (EIRP - Antenna Gain), where the EIRP is defined in the selected
Sub-Band.
In certain units with an integral antenna the Antenna Gain is not available as a
configurable parameter. However, it is available as a read-only parameter in the
applicable "Show" menus.
The lower limit for the Antenna Gain parameter is 0 (dBi). The upper limit for the
Antenna Gain is Regulation Max EIRP + 10 in dBi (since the minimum Tx Power is
-10dBm), up to a maximum of 50 (dBi). If Regulation Max EIRP is No Limit, the
upper limit is 50 (dBi). A value of "Don't Care" means that the actual value is not
important. A value of "Not Set Yet" means that the unit will not transmit until the
actual value (in the range 0 to 50) is configured. The unit can be configured to
"Don't Care" or "Not Set Yet" only in factory (when upgraded to SW version 2.0
from a lower version it will be set automatically to one of these options). Once a
value is configured, it is not possible to reconfigure the unit to either "Don't Care"
or "Not Set Yet".
The default value depends on unit type. In SUs with integral antenna it is set to
21 (read only). The default value for AUs that are supplied with a detached
antenna is in accordance with the antenna's gain. In units supplied without an
antenna the default is typically "Not Set Yet".
4.2.6.2.9 Cell Distance Parameters (AU only)
The higher the distance of an SU from the AU that is serving it, the higher the time
it takes for messages sent by one of them to reach the other. To ensure
appropriate services to all SUs regardless of their distance from the AU while
maintaining a high overall performance level, two parameters should be adapted
to the distances of SUs from the serving AU:
 The time that a unit waits for a response message before retransmission (ACK
timeout) should take into account the round trip propagation delay between
