Troubleshooting – 157
8.2.2 Checking the installation requirements
8.2.2.1 Checking the network infrastructure
If the link is not established after the installation on site, make sure that the devices were not damaged during
shipping, check the integrity of the network infrastructure, the cables and the power supplies.
8.2.2.2 Checking the installation requirements
Check if the suspension height, azimuth and elevation of the antenna match with the values obtained
from

. Make sure that the obstacles on the path profile are not higher than those specified during the
planning phase.

8.2.2.3 Interference detection
Web interface
Using the built-in Spectrum Analyzer tool, scan the air on both sides of the link to make sure there is no interference
that could corrupt the signal on the device's operating frequency and on the adjacent frequencies.The current
modulation (bit rate) will be selected by the device depending on the carrier to interference and noise ratio
(CINR).To operate at higher modulations, the CINR parameter must be greater or equal to 28 dB.To get accurate
information about the frequency, hover the mouse cursor over it.The pop-up window below provides information
about frequency, noise level (in dBm), maximum signal level (Max RSSI), average signal level (Average RSSI).The
"High RSSI" indicator allows to estimate the number of signal sources. If the value differs significantly from the
average RSSI, then there are several interference sources.The indicators show the signal level in dB, while the
signal in dBm is indicated in parentheses.
NOTE
It is recommended to run the spectrum scanning simultaneously on both devices to avoid a
misrepresentation due to the signal received from the remote device.
