Does rainy weather affects operating mikrotiks? I have noted
with a lot of concern whenever it's raining, most of my back hauls
links have crazy latencies. When sunny, same links are perfect.
Any idea?????

Rain will affect all microwave links.
The trick is to have enough margin to account for such events.

What are your signal strengths and SNR?

My signal is -70dbm on both mikrotiks. Kindly explained what
you meant by enough margin please.

Thanks

Hi David,

Here in Australia rain definately affects DSL connections. It's actually so bad that you can hear the crackle on the phoneline when it rains. It definately affects upstream and downstream data speeds.

SNR = Signal to noise ratio.
Signal-to-noise ratio compares the level of a desired signal to the level of background noise. The higher the ratio, the less obtrusive the background noise is

A goal would be to maintain all your backhauls with 20db or more Signal to noise.

What's the distance on your link and frequency you're using? You will get some rain fade, and it's measured per mile...so the longer the link the more rain fade you will suffer. What's the difference in signal on a clear day vs. rainy. I'm assuming -70 is "sunny weather". What is it during the rain? In any case "crazy" latency shouldn't be occuring if the shot is engineered properly. As was previously noted, measure the noise floor at both ends and make sure that received signal is at least 20db better. If you're running your links horizontally polarized, try flipping one to vertical and watch it during the next storm. Also, during these rain storms is it windy...and if so how's the vibration protection on your antenna?
