Operation 214
4. Adjust the optimal RSSI that must be reached when the beams are close to the central region, as
shown in Figure 233 .
Figure 233:
The optional RSSI alignment
The RSSI time series must be close to the Link planner's predicted RSSI (the receive level when
aligning, as shown in
Figure 234 ), with an error of +/-5dB. Consider the following points when
adjusting the optional RSSI:
l
If the time series reporting RSSI is more than 10dB from that of the Link Planner’s expected
RSSI, then the device has been aligned incorrectly and is being picked up by the sidelobes
or spurious beams.
l
If a cell is highlighted and the time series reporting RSSI is more than 10dB off the expected
RSSI, then it is necessary to sweep beyond the current position of both azimuth and
elevation, in turn to ride past the sidelobes.
