Corrective ActionPossible CauseIndication
• Visually inspect cables/connectors
• Sweep cable
• Change cable/connectors
Bad cable
• Bench test the radio to confirm configuration
• Reconfigure radio
Incorrect radio configuration
• Check LOS for obstacles such as trees
• Change alignement of antenna to take advantage
of beneficial multipath signals
• Increase antenna height to obtain clearance
• Move antenna to better location or remove
obstacle if possible
No Fresnel zone clearance or
severe NLOS
• Perform RSSI test to determine fade margin
• Check for obstacles in RF path
• Check for interference
• Point antenna in different directions to take ad-
vantage of beneficial multipaths
• Reposition LibraPlus or antenna to establish
better LOS
• Replace LibraPlus and perform bench test
Signal strength too lowHigh packet loss
• Change center frequency
• Increase RF power
• Change polarization of antennas
• Get separation or change physical location of
antenna
Interference
• Determine if ambient operating temperature is
too high or low
• Increase or reduce ambient temperature
