Does the condition of the air (Humidity, temp ect.) affect wireless performance?

Question

It seems that I lose my wi-fi connection more often when humid. I have asked a person who works for Raytheon on radar systems. He says no, however I feel that he may be a bit rusty on this subject.

I'm talking about indoor wi-fi by the way

Answer 1

Weather has a lot to do with it. it's the same as wireless systems. In bad weather wireless computer network is very slow.

Answer 2

Your friend from Raytheon gave you a practical response. In other words, there is really no noticable effect on indoor wifi. Even outdoors the apread spectrum stuff tends to be negligably effected by humidy or even rain - a bit more defraction perhaps, adding a bit more noise to your SNR (signal-to-noise) ratio, but not much of an issue. And certainly no real concerns over tropospheric ducting and the like.

Answer 3

There are a lot of things that affect signals of all types, one of them can be static build up in the air and some types of weather can also.

Humidity may have an affect, and if you say it happens mainly when it is humid then it is very possible I would think.

Answer 4

Humidity means proportion of water molecules in air.When this is high radio waves collide with them causing energy loss.Waves that r sent 2 submarines shud pass through water hence they r AM waves having less freq & more wl.But the signals in W/l Commn r opposite(FM).There is much loss of energy in humid n rainy climates.Temperature has not much effect on w/l.
