My link normally performs well, but from time to time it gets shaky. What could be the reason for that?

My link normally performs well, but from time to time it gets shaky. What could be the reason for that?

Possible reason Suggested action
Tidal waves (link mounted over water and antennae are not moving) –         Use narrow-beam antennae (less multipath fading, better link budget)

–         Use narrower channels (20MHz rather than 40-80MHz)

–         Monitor link trend in Repeatit’s cloud service

Tidal waves (link mounted over water and antennae are moving since they are mounted on a boat etc.) –         User wider beam antennae (23dBi etc.)

–         Consider configuring a multipoint system (requires an extra non-Repeatit box behind the client links to steer traffic right)

Link signal quality (RSSI) drops –         Is the link configured over water? If yes, see above.

–         Check the cloud management system to figure out when the RSSI dropped. Can it be related to some specific event (e.g. someone climbed the mast the same day)?

–         Did it drop on both sides of the link or just one? Did it drop for both antenna chains or just one? Collect information and contact your support if nothing of the above helps.

Link performance goes down –         Check the signal strength (RSSI bars) on both sides of the link. If they are all over 23-25dB it is normally ok.

–         Check the PHY Errors rate and Checksum Errors rate on both sides. If it has gone up on one of the sides, it could indicate interference from some other system. Perform a spectrum scan and look for another channel.
